Keyboard Shortcuts in the SoftLayer Customer Portal

I’m excited to introduce a new feature in the SoftLayer customer portal: Keyboard shortcuts!

Keyboard shortcuts give you quick access to the most commonly used features by simply typing a few characters. For those who prefer never having to reach for the mouse to navigate an application, you should find these handy additions quite helpful.

After you log into the Customer Portal, type “?” (shift + forward slash) on any page, and you'll see a full list of available keyboard shortcuts:

Keyboard Shortcuts

On the Keyboard Shortcuts help page, you have the option to enable or disable the functionality based on your preference. Keyboard shortcuts are enabled by default. Disabling this feature will turn off all keyboard shortcuts except the “?” shortcut so that you can access the enable/disable feature preference in the future if you change your mind. This preference is stored in a cookie in your browser, so changing computers or deleting your cookie will re-enable the feature.

The shortcuts are grouped into three sets: Global, Tabs, and Grids.

Keyboard Shortcuts

Global Navigation

You have the ability to navigate to any page in our application by typing in the respective position number in the menu combined with dashes (-). For example, typing 1-5-2 will open Support (1) > Help (5) > Portal Tour (2).

Use the “go to” key combinations to jump to a new location from anywhere in the portal. For example, type (g) and (d) to visit the Device List. Typing (g) and (u) allows you to access the list of portal users, and (g) and (t) takes you to view tickets. If you want to add a new ticket from anywhere in the portal, type (+) and (t). It’s that simple.

Keyboard Shortcuts

Tabs

Many of the pages within the portal have tabs that appear just above the main content of the page. These tabs often allow content to be filtered, or provide access to additional features related to the page topic. Each tab can be accessed by using a simple two-keystroke combination, such as (t) then (f) to reveal the Filter tab on the page.

Keyboard Shortcuts

Grids

Whenever a page contains a grid — a tabular listing — you can now perform common operations from the keyboard. Jump quickly from page to page (first/last or next/previous) or refresh the grid contents with a single keystroke.

Keyboard Shortcuts

Please give this new feature a try for yourself! We welcome your feedback. Please let us know if you would like to have us implement any other keyboard shortcuts in the future.

New App Release: SoftLayer Mobile for Windows 8.1

Today, the SoftLayer development team is launching a new platform accessibility tool for SoftLayer customers who want to easily manage their infrastructure from Windows. We've gotten a great response from the users of SoftLayer Mobile app for Windows Phone, so we turned our attention to creating an app for customers on Windows 8.1: SoftLayer Mobile for Windows 8.1.

With a growing number of users adopting and embracing Windows 8.1 on their PCs, and the Windows Store is becoming a vibrant community of useful apps for those customers. There are more than 145,000 apps on the Windows Store, and that number is expected to increase exponentially following Microsoft’s recent introduction of "Universal Apps for Windows Phone 8.1 and Windows 8.1.” With all that goodness and an expanding market, it was imperative for our mobile development team to build an app for customers using Windows 8.1 as their default OS or carrying Windows RT tablets.

Why Windows 8.1?

Our team wants to provide simple, efficient ways for customers to connect to SoftLayer infrastructure and perform any necessary management tasks while on-the-go. Our team is inspired by the power of connected devices in Windows ecosystem. By developing an app for Windows 8.1, we will slowly bring the phone, tablet and PC onto one streamlined platform — a concept many smart devices are adopting quickly.

What’s Fresh?

New Dashboard

The SoftLayer Mobile app for Windows 8.1 is a fresh new approach to its Windows Phone sibling. The app provides a dashboard view after authentication that provides a snapshot of some of the most commonly used information and controls in the portal.

Currently, the dashboard supports four different panels: Tickets, devices, accounting and bandwidth. All display an overview of relevant information for you and your environment. The dashboard also allows you to quickly add a ticket or make a one-time payment on your account.

SoftLayer Mobile for Windows 8.1

In-line Ticket Updates

In the new tickets module, you can update tickets without ever leaving the page. This functionality is similar to what you see on many social websites, and it's integrated to be seamless.

SoftLayer Mobile for Windows 8.1

Search Everywhere!

One of the coolest additions to the new app is the introduction of search functionality in each module. Now, you can search a ticket, a device, or an invoice by just typing into the search box! The search capability lets you spend less time scrolling and more time working.

SoftLayer Mobile for Windows 8.1

Bandwidth Display

Smart phones have apps that measure and report how much data you are using, and your infrastructure should be similarly transparent Bandwidth usage is an important aspect of server management, so we built the bandwidth module to show your infrastructure's public and private traffic for current and previous billing cycles. This view also helps you see when a server is about to reach its limits so that you can plan accordingly.

SoftLayer Mobile for Windows 8.1

The module provides two ways to look at the data:

  • In a tabular form by clicking the “Show/Hide Traffic Details” button.
  • In a graphic representation by clicking the “View Graph” button.

SoftLayer Mobile for Windows 8.1

Same Functionality. Better Experience.

Sometimes change is not always needed for a nicely crafted feature. The new app keeps the same feature richness of the Windows Phone app and arranges it in a user-friendly way. For example, in the devices module, you can navigate to between different tabs to get the information you need, from password lists and attached tickets to a specific device or monitoring alarms.

The “Remote Control” section on the module allows you to perform actions such as rebooting, power cycles, restarts and pinging servers. In addition, you can view hardware and software installed on the device along with the hardware and network components attached. In the current phone version, you can only see the root password for the device, but in the Windows 8.1 app, you see all passwords for the server.

SoftLayer Mobile for Windows 8.1

What's Next?

During the development of this app, the team's goal was to test to adopt a framework that would be ideal for scaling. More and more developers are adopting a Model-View-Model (MVVM) approach to mobile and web app development, so our goal was to use that approach for this project. The significant challenge we faced when adopting this approach was finding a well-supported framework that met our application's needs. We weren't able to find suitable frameworks that committed regular updates in SDKs or in APIs, so we ended up using the same MVVM principles without any underlying framework. In the end, the project allowed us to create our own framework for future projects!

There are many exciting features that are lined up for the Windows 8.1 app. Download it now: SoftLayer Mobile for Windows 8.1

After you try it out, please submit your feedback ... We want to keep improving the app by providing the features and functionality that matter most to you.

The Media Industry is Making the Move to Cloud

Rumor has it that at the entire rendering of James Cameron’s “Avatar” using 3DFusion required more than 1 petabyte of storage space. This is equivalent to 500 hard drives of 2 terabytes each, or a 32 year-long MP3 file! The computing power behind this would consist of about 34 racks, each with 4 chassis containing 32 machines. All of that adds up to roughly 40,000 processors and 104 terabytes of RAM.

High-res, long-form media files that can reach hundreds of gigabytes of storage are regular phenomena in the media industry. Whether it’s making the next “Avatar” or creating the next big, viral ad campaign, technology is fundamental to the media industry. But, the investment required to set these up is enough to boggle the mind and dissuade even the high risk-takers. So, why buy when you can rent?

Cloud allows you to rent, own, use, and return the infrastructure with no capex. That gives users access to unlimited compute power, including servers, network, storage, firewalls, and ancillary services, all available on demand, with pay-as-you-go billing offered hourly or monthly.

Cloud services are an increasingly viable avenue for the industry to leverage and support the performance needs of online media storage, as well as collaboration environment. The benefits of a customizable approach to the cloud include: digital archives, production support, broadcast facility resiliency, high-intensity processing, and derivatives manufacturing for transcoding and encrypting. An on-demand, scalable infrastructure is the next step toward reducing production and operations costs, simplifying data access, and delivering content faster to the end user.

This year at ad:tech asean, SoftLayer will present on how the media industry is utilizing cloud infrastructure. So, I thought this would be a good opportunity to share some interesting customer stories about media companies at the top of their games and successfully growing their businesses on the cloud. Here are two of those stories.

The Loft Group, an Australian creative digital agency, specializes in creating e-learning campaigns for global brands. The company won a contract with cosmetics giant L’Oreal but realized that in order to go big with their platform, they needed technology that provided their support team with the necessary analytics. The Loft Group selected SoftLayer as the cloud platform for its digital e-learning campaigns. Moving their services to the cloud helped the company achieve global scale, consistent performance across multiple countries and grow at a pace which slashed a 3- to 5-year transformation timeline down to just months.

According to eMarketer’s forecast, global e-commerce sales will top $1.2 trillion by 2016. That growth is projected to continue by 20 percent every year. Ad personalization is playing a larger part in maximizing e-commerce business. To keep up with the demands of real-time ad personalization, companies like Struq, an ad personalization platform, require an infrastructure that can process high volumes at high speeds.

Struq offers highly targeted ad campaigns across a range of promotional platforms. The company often handles more than 2 terabytes of raw event data every day, processing more than 95 percent of requests in fewer than 30 milliseconds. And when the company’s growing European customer base demanded immediate server allocation, Struq turned to SoftLayer for scalability. We were able to offer on-demand provisioning as well as the low latency their customers required. A detailed story of how Struq achieved the requisite scalability and success with SoftLayer is available here.

More stories to come, so stay tuned! In the meantime, you can hear more customer stories during the first leg of ad:tech asean, a prelim roadshow in Jakarta, Kuala Lumpur and Bangkok.

Security: 10 Tips for Hardening a Linux Server

In light of all the complex and specialized attacks on Internet-facing servers, it’s very important to protect your cloud assets from malicious assailants whose sole purpose is to leach, alter, expose, siphon sensitive data, or even to shut you down. From someone who does a lot of Linux deployments, I like to have handy a Linux template with some extra security policies configured.

Securing your environment starts during the ordering process when you are deploying server resources. Sometimes you want to deploy a quick server without putting it behind an extra hardware firewall layer or deploying it with an APF (Advance Policy Firewall). Here are a couple of security hardening tips I have set on my Linux template to have a solid base level of security when I deploy a Linux system.

Note: The following instructions assume that you are using CentOS or Red Hat Enterprise Linux.

1. Change the Root Password
Log in to your server and change the root password if you didn’t use a SSH key to gain access to your Linux system.

  • passwd - Make sure it’s strong.
  • Don't intend on using root.

2. Create a New User
The root user is the only user created on a new Linux install. You should add a new user for your own access and use of the server.

  • useradd <username>
  • passwd <username> (Make sure this is a strong password that’s different from your root password.)

3. Change the Password Age Requirements
Change the password age so you’ll be forced to change your password in a given period of time:

  • chage –M 60 –m 7 –w 7 <username>
    • M: Minimum of days required between password changes
    • m: Maximum days the password is valid
    • w: The number of days before password will warn of expiration

4. Disable Root Login
As Lee suggested in the last blog, you should Stop Using Root!

  • When you need super-user permissions, use sudo instead of su. Sudo is more secure than using su: When a user uses sudo to execute root-level commands, all commands are tracked by default in /var/log/secure. Furthermore, users will have to authenticate themselves to run sudo commands for a short period of time.

5. Use Secure Shell (SSH)
rlogin and telnet protocols don’t use an encrypted format, just plain text. I recommend using SSH protocol for remote log in and file transfers. SSH allows you to use encryption technology while communicating with your sever. SSH is still open to many different types of attacks, though. I suggest using the following to lock SSH down a little bit more:

  • Remove the ability to SSH as root:
    1. vi /etc/ssh/sshd_config.
    2. Find #PermitRootLogin yes and change to PermitRootLogin no.
    3. Run service sshd restart.
  • Change the default SSH 22 port. You can even utilize RSA keys instead of passwords for extra protection.

6. Update Kernel and Software
Ensure your kernel and software patches are up to date. I like to make sure my Linux kernel and software are always up to date because patches are constantly being released with corrected security flaws and exploits. Remember you have access to SoftLayer’s private network for updates and patches, so you don’t have to expose your server to the public network to get updates. Run this with sudo to get updates in RedHat or CentOS: yum update.

7. Strip Your System
Clean your system of unwanted packages. I strip my system to avoid installing unnecessary software to avoid vulnerabilities. This is called “reducing the attack surface.” Packages like NFS, Samba, even the X Windows desktops (i.e., Gnome or KDE) contain vulnerabilities. Here’s how reduce the attack surface:

  • List what is installed: yum list installed
  • List the package name: yum list <package-name>
  • Remove the package: yum remove <package-name>

8. Use Security Extensions
Use a security extension such as SELinux on RHEL or CentOS when you’re able. SELinux provides a flexible Mandatory Access Control (MAC); running a MAC kernel protects the system from malicious or flawed applications that can damage or destroy the system. You’ll have to explore the official Red Hat documentation, which explains SELinux configuration. To check if SELinux is running, run sestatus.

9. Add a Welcome/Warning
Add a welcome or warning display for when users remote into your system. The message can be created using MOTD (message of the day). MOTD’s sole purpose is to display messages on console or SSH session logins. I like for my MOTDs to read “Welcome to <hostname>. All connections are being monitored and recorded.”

  • I recommend vi /etc/motd

10. Monitor Your Logs
Monitor logs whenever you can. Some example logs that you can audit:

  • System boot log: /var/log/boot.log
  • Authentication log: /var/log/secure
  • Log in records file: /var/log/utmp or /var/log/wtmp:
  • Where whole system logs or current activity are available: /var/log/message
  • Authentication logs: /var/log/auth.log
  • Kernel logs: /var/log/kern.log
  • Crond logs (cron job): /var/log/cron.log
  • Mail server logs: /var/log/maillog

You can even move these logs to a bare metal server to prevent intruders from easily modifying them.

This is just the tip of the iceberg when securing your Linux server. While not the most secure system, it gives you breathing room if you have to deploy quick servers for short duration tests, and so on. You can build more security into your server later for longer, more permanent-type servers.

Sysadmin Tips and Tricks - Stop Using Root!

A common mistake newer Linux system administrators make is the overuse of root. It seems so easy! Everything is so much simpler! But in the end, it’s not—and it’s only a matter of time before you wish you had not been so free and easy with your super-user, use. Let me try to convince you.

Let’s start with a little history. The antecedents of Linux go all the way back to the early 1970s, when computers cost tens of thousands of dollars (at least). With that kind of expense, you as a user would hardly have a computer sitting on your desk (not to mention they were at least refrigerator-sized), and you would also not have the use of it dedicated to your needs. What was obviously needed was an operating system that would allow multiple users to use the machine at once, via terminals, in order to make the most use of the computing resources available.

If you think about it, it’s clear that the operating system had to be very good at keeping users from being able to stomp on each other’s files and processes. So the early UNIX™ variants were multi-user systems from the get-go. In the ensuing forty years, these systems have only gotten better at keeping the various users and processes from harming each other. And this is the technology that you’re paying for when you use Linux or other modern variants.

Now, you may think, “That doesn’t apply to me—I’m the only user on my server!” But are you, really?

You probably run Apache, which is generally run as the user httpd or apache. Why not root? Because if you run Apache as root, then anyone on the outside who manages to get Apache to execute arbitrary code, would then have that code running as root! Next thing you know, they can execute "rm –rf /," or worse, invade your system altogether and steal proprietary information. By running as a non-root user, even if the attacker gets total access to that user, they are limited to what that user can touch. Thus, user httpd is compromised, but not the entire server.

The same thing is true for mail servers, FTP servers, and so on. They all rely on the Linux permissions system in order to give the programs access to as little as possible—ideally, only exactly what they need to do their jobs.

So, think of yourself as another process on the system. When you log in as your regular user, you are limited in what you can do. But this is not intended to harm you or irritate you—indeed; the system is designed to keep you from accidentally doing damage to your server.

For example, consider if you wanted to completely remove a directory called ‘home’ within your home directory. Note the ever so slight difference between the first command:

rm –R home

And the second command:

rm –R /home

The first command removes a directory called ‘home’ from wherever you happen to be sitting on the file system. The second removes all users’ home directories from the system. One little slash makes all the difference in the world. This is probably why it has been said that Linux gives you enough rope to hang yourself with. Executing the second command as root looks like this:

server:# rm –R /home 
server.com#

And it’s just gone! Whereas if you accidentally put that slash in there while logged in as your user, you would get:

server:# rm –R /home 
server:# rm: cannot remove `home’: Permission denied

This will annoy you, until you realize that if you’d done it as root you would have wiped out all your customers home directories.

In short, just like the processes that run on your machine, you would be well served to use only the permissions you need. This is why many Linux distributions today encourage the use of sudo—you don’t even become root, but just execute things as root when needed. It’s a good policy, and makes the best use of four decades of expertise that have gone into the system you are using.

P.S. This is also why you pretty much never want to chmod 777 anything!

Deep in the Heart of Te(ch)xas: SXSW 2014

SXSW 2014 was bigger and crazier than ever. For anyone who has been sleeping under a rock, SXSW is one of the largest, most intense start-up technology, music, and film festivals on the planet. Held in March, SXSW turns Austin, Texas, into the global epicenter of everything (startup) technology.

As in years past, SoftLayer hosted the Speakeasy lounge, a daytime co-working space and community/networking lounge in the evening. For the second straight year, the lounge blew our expectations out of the water. Over the course of 48 hours, we saw over a thousand partners, start-up clients, fellow colleagues, and members of the global start-up community come through the doors. To give you an idea of how “global” the community was, I walked through the lounge at one point and heard six different languages being spoken.

Our start-up partners used the lounge to escape the chaos of the festival so they could get work done. In the space, they could relax, send emails, connect with clients and friends, or just find some peace and quiet away from the cacophonous show floor (and even-noisier 6th Street).

Catalyst Lounge SXSW 2014

One of the biggest highlights at SXSW for the Catalyst team was a panel that I moderated about building meaningful, organic communities around brands. The panelists for this discussion were George Karidis, COO of SoftLayer; Ben Rigby, CEO of Sparked; Samar Birwadker, CEO of Good.co; and Justin Johnson, director of developer evangelism for Keen.io. The group explained how their brands’ approaches to community engagement helped them build momentum and succeed faster, and I was humbled to hear how the SoftLayer Catalyst program impacted their decisions shaping their own communities. To cap off the session, the panelists also brought up the benefits of using Catalyst for testing and scaling during their early stages, so they could understand how to use the infrastructure as they grew. You need look no further for validation of our model than to have three of our most successful clients attributing their success to it.

In addition to the Speakeasy and the panel discussion, SoftLayer was also well represented on the SXSW show floor. Over the course of the show, clients, partners, and prospects stopped by to try their hands at the Server Challenge, and we had some phenomenal conversations about the future of the cloud and how SoftLayer is forging a new path in the infrastructure as a service game.

What a lot of people don’t realize about SXSW is that the majority of business gets done outside of the show floor. Each night presents opportunities to connect with and learn about individuals in the global start-up community. For example, Catalyst partner Planwise held a party and barbecue where they discussed best practices for start-ups in financial technology. We got in on the fun as well when we partnered with Techstars to host one of the hottest parties at SXSW Interactive. DJed by Thievery Corporation and attended by over a thousand guests, if you managed to get a hard-to-come-by ticket, you had a great time and met a lot of amazing people.

SoftLayer & Techstars Party SXSW 2014

Over the years, SXSW has proven to be a melting pot for creativity and innovation on a global scale. As businesses look for new ways to gather and present information, providers like SoftLayer become an integral part of their approaches. Our goal with Catalyst is to stay front-and-center in the startup movement … So it’s a safe bet that you’ll see us again at SXSW 2015.

OpenSSL Heartbleed Update

On April 7th, the OpenSSL Project released an update to address a serious security flaw (CVE-2014-0160), which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.

SoftLayer Infrastructure

After notification of this vulnerability we began a close examination of our services to determine any that may have been affected. Both the SoftLayer customer portal and API are serviced behind hardware load balancers and neither the hardware load balancers nor the software running on the servers behind them were found to be running vulnerable versions of OpenSSL. This was confirmed by the hardware vendor and direct testing as well. During these tests it was discovered that certain nodes of our Object Storage cluster were running a vulnerable version of OpenSSL. The software was immediately patched to remediate the issue. Although there is no indication that this vulnerability was exploited, the subset of customers potentially affected has been advised of precautionary measures to ensure continued security.

Additionally, our team forced updates to all of our internal operating system update mirrors as soon as patched versions were released by their publishers. Our system automatically checks for and updates all operating system versions hosted on our mirrors, but due to the urgency of this exploit, manual updates were run as quickly as possible to have patched versions available sooner.

SoftLayer Customers

Due to the nature, surface area, and severity of this vulnerability, we recommend revoking all possibly compromised keys and reissuing new certificates for any service secured using the OpenSSL library. The rekeying process can vary depending on your Certificate Authority (CA) and you should contact them if you have questions on how to complete this process. This OpenSSL vulnerability has major security implications for a wide range of operating systems and applications and may necessitate rebooting your hardware (or restarting services) to ensure all services linking against the affected code use the updated version of the OpenSSL library. We also recommend that you patch all of your servers and change passwords as soon as possible. Take this opportunity to review your overall password strategy including password strength and password sharing across sites.

Sprint Accelerator Spices Up Silicon Prairie

As part of the community development team here at SoftLayer, I get to travel the world and reach into cities to help local, born-on-the-Web communities grow and prosper. Last week, my travels took me (and my rock star team) to Kansas City, where we were invited to mentor startups in the Sprint Mobile Health Accelerator powered by TechStars (PBTS).

I know when you think of KC, you might not think of a technology startup community. As part of Silicon Prairie, where startups and tech are thriving, KC is taking its place amongst US tech communities, as companies like Sprint, Garmin, H&R Block, and Hallmark are investing in the local startup community.

Through the course of the days I spent in KC, we talked to 10 startups and held technical office hours. What we learned is that the startups in this accelerator had all of the qualities we hope to find: grit and determination coupled with brains and insane talent. (And some of the teams we met with are growing so quickly that they even have open positions.)

What struck me most from my trip was the sheer fact that even though I live in the epicenter of all things tech startup, I can see with my own eyes that the rest of the world is catching up––and they are doing so quickly. Most of the teams at Sprint PBTS are not from the startup mega cities like New York and San Francisco. They are from places off the beaten path. I’m happy to see it, and I’m even more excited for my trips later this year to other parts of the country like Memphis, Detroit, and Okanagan, where I’m sure to be as impressed as I was with KC.

True, for the time being the venture capital and investment communities will likely still steer startups toward the Bay Area, but I’m not convinced that is a trend that will continue forever. I’m more and more certain that as we advance technologies—and as SoftLayer maintains its edge in building the best platform on which to create them––geography will become a secondary factor in the success of startups.

Our Catalyst Startup Program provides that platform for early stage startups around the globe. Members have innovative concepts that need reliable infrastructure to support their growth from idea to enterprise. Recently, I sat down in front of a camera to share an overview of the program and it's benefits from the perspective of Catalyst member HAUL. Here is a crash course on Catalyst:

I believe in a year, a few of the teams from the Sprint Mobile Health Accelerator will combine forces to create one company that will eventually become a household name. Their evolution will be fun to watch from the beginning to end. And we are going to watch them closely. They’re going to do it, and we are going to be with them every step of the way.

An Inside Look at IBM Cloud Event 2014 in Hong Kong

On March 17 in Hong Kong, IBM and SoftLayer successfully concluded the first of many intimate cloud events. IBM Cloud Event 2014 marked the beginning of the $1.2 billion investment committed towards our global expansion plans.

Growing from 13 to 40 data centers is no mean feat, and Hong Kong is the starting point. Not only does this give our customers data redundancy in Asia-Pacific, but also provides data residency to our Hong Kong-based customers. Quite simply, we are growing where you want to grow.

For me, there were three key takeaways from the event.

We’re seeing overwhelming support from our customers.
Not only did we have an opportunity to host our Hong Kong clientele, but many also traveled from cities in Greater China to be a part of this milestone. It was immensely gratifying to see them being vocal advocates of SoftLayer services. Natali Ardianto from Tiket.com, Chris Chun from 6waves and Larry Zhang representing ePRO all shared their brilliant stories with the audience.

Tiket.com’s co-founder, Natali, is especially proud of the fact that the company sold out 6,000 tickets for the K-Pop Big Bang Alive concert in 10 minutes, while their competitor’s site was unable to meet the huge demand and shut down for four hours during the peak period. Tiket.com, founded in 2011, faced TCP, DoS and DDoS attacks and tried hosting unsuccessfully on two different IaaS providers before moving to SoftLayer’s infrastructure services in 2012.

6Waves, a gaming publisher, was started in 2008. Today, built on SoftLayer, 6waves has grown to the #1 third-party publisher on Facebook. 6waves manages 14 million monthly active users and 2 million daily active users. Chris, 6waves’ CTO and co-founder, shared that since 2009 6waves has launched more than 200 games on SoftLayer.

Larry Zhang, ePRO’s senior IT manager and architect, had a similar story to share. The B2C e-commerce platform, part of China-based DX Holdings, supports more than 200,000 items in 15 categories and saw a 66 percent increase in customers from October 2011 to September 2013. ePRO is now looking to cater to the US and Australian markets, and Larry believes that SoftLayer’s aggressive expansion plans will help them meet their goal.

SoftLayer in Hong Kong

There is a vested interest in the SoftLayer-IBM integration roadmap.
Large enterprises are moving towards the cloud. This is not a forward-looking statement, it's a fact. And from the feedback gathered and the questions put up by these organizations, it is clear that they are investing in leveraging cloud services for improving their internal processes and for bringing services to their end customers more quickly. Lance Crosby presented a SoftLayer-IBM integration roadmap. With SoftLayer forming the foundation of IBM's cloud offerings—SaaS, PaaS and BPaaS—there is no doubt that we are as invested in this partnership as our clientele.

The strong startup community in Hong Kong is committed to growing with Softlayer.
Catalyst, SoftLayer's startup incubator, has always had a strong presence in Hong Kong, and the startup spirit was evident on March 17 as well. The dedicated roundtable conducted for the community with Lance Crosby and Casey Lau, SoftLayer's Catalyst representative for APAC, was the highlight of the day. Lance left us with a powerful thought, "We are here to be an extension to your infrastructure... The question is what can you build on us."

All in all, this was a great start to our new journey!

Name Servers: Don't Get Lost in (Domain) Translation

The Domain Name System (DNS) is vital to keeping the Internet in order and easily accessible. Every byte on the World Wide Web lives in (at least) one specific place on the planet, and it's mapped to that location with an IP address like 66.228.118.53 (IPv4) or 2607:f0d0:4545:3:200:f8ff:fe21:67cf (IPv6). DNS translates the domain names you know and love to the correct IP addresses, so without DNS, you would have to memorize a 32-bit or 128-bit IP address for your favorite websites. Remember the last time your cell phone died? How many phone numbers did you have memorized?

There are plenty of resources available online to explain How DNS Works, so in this post, we'll focus on the basics of how we use DNS. Here's the scenario: We want to register a domain — softlayer.com — and make it available to the masses.

1. Reserve and Register a Domain Name
The first thing we need to do is purchase and register our domain name. To do this, we need to choose a domain registrar and verify that our domain is available. Every domain registrar effectively provides the same service: It will reserve an available domain on your behalf, and it will let you dictate where that domain will live. There's not a lot of differentiation or value-add in that service, so many registrars offer cheap or free domains as loss-leaders for higher margin hosting or Web services. Be sure to check the fine print to make sure you're not committing to a year of hosting to get a $0.99 domain name. Some registrars make the process of updating and configuring where a domain resolves more difficult than others, but for the sake of this example we'll assume that your registrar allows the same easy accessibility SoftLayer provides our customers in the customer portal.

The domain name we want is softlayer.com, and in this example, that domain name is available for us to reserve. Once we go through the ordering process, we'll need to associate the domain with a set of authoritative name servers. Authoritative name servers are effectively the go-to address book for a specified domain. By default, your domain registrar will provide name servers for your domain, but they can be changed easily to meet your needs. You have four typical options when it comes to choosing your domain's name servers:

  • Use the domain registrar's default name servers.
  • Use you hosting provider’s name servers.
  • Use a third party DNS service to manage your domain names.
  • Run your own name servers on your server to manage your domain names.

Each of these options has its own pros and cons, but because we're just interested in getting our domain online, we'll use SoftLayer's DNS control panel to manage our new domain name.

2. Create DNS Records
When we access our hosting provider's DNS control panel, we see this:

This is an extremely high level view of DNS, so we’re just going to focus on what we must have in order to make softlayer.com reachable via browser. The first thing we'll do is add a DNS zone. This is usually our domain, but in some situations, it can be a bit different. In this example, we'll create a “softlayer.com” zone to be responsible for the whole softlayer.com domain:

With that zone created, we now need to add new "Address Records" (A Records) within that zone:

The terminology used in different DNS control panels may vary, so let’s breakdown what the four sections in those screenshots mean:

  • Resource Type: This is our DNS record type. In our example, we have A records which link a hostname to our IP address. There are a number of DNS record types, each serving a different purpose.
  • Host: This is the host node or owner name — the name of the node that this record applies to. Using the @ symbol in the A record allows visitors to reach our website without the leading www. If we wanted blog.softlayer.com to live at a different IP address, we'd make that happen here.
  • Points To: This is the IP address of the host node. You might see this section referred to elsewhere as content, data or value. The standard term is RDATA — resource record data. This is specific to each data type.
  • TTL (Time-to-Live): TTL dictates how long your name server should keep a particular record before refreshing for possible updates. Generally speaking, longer TTLs work well if you’re just adding new entries and or don’t anticipate frequent record changes.

Once we save these changes in our DNS control panel, we play the waiting game. Because these DNS changes have to propagate across our DNS servers to be accessible to the Internet as a whole, the process typically takes 24-48 hours, if not sooner. SoftLayer’s customer portal has DNS check built-in as one a few different network tools. If you aren't a current customer, you can use What's my DNS? This is what the SoftLayer tool looks like:

3. Create rDNS Records
The last step we want to take in setting up our domain is to create Reverse DNS (rDNS) records. These records do the same thing as DNS records, but (as the name suggests) they function in the opposite direction. With rDNS, we can assign an IP address to a domain name. This step isn't required, but I recommend it to help ensure better performance of online activities like email and website visitor tracking.

DNS is a central piece of the Internet as we know it, so by understanding how to use it, you'll have a much better understanding of how the Internet works. It seems challenging at first glance, but as you see from this simple walkthrough, when you break down and understand each step, you won't get overwhelmed. A wealth of DNS tools and tutorials are available for free online, and our DNS documentation might be a great resource to bookmark so you'll never get lost in domain translation.
