Opening Up the Cloud

This guest blog post is written by Alexia Emmanoulopoulou, marketing manager at Canonical.

With OpenStack, cloud computing becomes easily accessible to everyone. It tears down financial barriers to cloud deployments and tackles the fear of lock-in. One of the main benefits of OpenStack is the fact that it is open source and supported by a wide ecosystem, with contributions from more than 200 companies, including Canonical and IBM. Users can change service providers and hardware at any time, and compared to other clouds using virtualization technology, OpenStack can double server utilization to as much as 85 percent. This means that an OpenStack cloud is economical and delivers more flexibility, scalability, and agility to businesses. The challenge however lies in recruiting and retaining OpenStack experts, who are in high demand, making it hard for companies to deploy OpenStack on time and on budget. But BootStack, Canonical’s managed cloud product solved that problem by offering all the benefits of a private cloud without any of the pain of day-to-day infrastructure management.

Addressing the Challenge of Finding OpenStack Experts

Resourcing an OpenStack six-strong team to work 24x7 would cost between $900,000 and $1.5 million and can take months of headhunting. Thus the savings that OpenStack should bring companies are eroded so Canonical created BootStack, short for Build, Operate, and Optionally Transfer. It’s a new service for setting up and operating an OpenStack cloud, in both on-premises and hosted environments, and it gives users the option of taking over the management of your cloud in the future.

After working with each customer to define their requirements and specify the right cloud infrastructure for their business, Canonical’s experienced engineering and support team builds and manages the entire cloud infrastructure of the customer, including Ubuntu OpenStack, the underlying hypervisor, and deployment onto hosted or on-premises hardware. As a result, users get all the benefits of a private cloud without any of the pain of day-to-day infrastructure management. For added protection, BootStack is backed by a clear SLA that covers cloud availability at the user’s desired scale as well as uptime and responsiveness metrics.

Choosing Between On-premises and Hosted Cloud

Some companies prefer to host on-premises because they feel more secure knowing their cloud is running on their own site. However, when things go wrong, some companies find they don’t have the expertise on-hand to quickly recover. Furthermore, on-site hosting is at least three times as expensive as it is to outsource to a hosting specialist.

With the hosted option for BootStack, your OpenStack cloud will be hosted on Ubuntu-certified hardware in SoftLayer data centers. SoftLayer provides customizable bare metal and virtual servers run on the highest performing cloud infrastructure available. Users can seamlessly move data between servers at no cost and benefit from secure, fast, and low-latency communications between data centers. 24x7 expert staff in each data center can troubleshoot any rare issues that can’t be directly resolved through their self-service management portal. Canonical and SoftLayer also take care of patches and upgrades to both the operating system and OpenStack, hardware and software failure prevention and fix, proactive health monitoring of the cloud and hardware, and resolution of any other problems.

No Lock-In and Predictable Cost

The two features that set BootStack apart from other managed cloud products are the predictable cost structure and the lack of lock-in. With BootStack, users can access every tool and every machine, any time. A company can choose to take over the management of its cloud at any time, at which point it will receive training and support from Canonical to ensure a smooth transition. BootStack customers can then choose to either bring their cloud in-house or continue hosting with SoftLayer.

In terms of costs, BootStack cloud is priced at $15 per day per server, plus the cost of the hosting. SoftLayer offers a number of bare metal servers that exceed the OpenStack recommended configuration, starting at $699 per month. You pay as you go, and can scale as your business needs change.

All-in-all, it’s a flexible managed cloud at a predictable cost with expert staff to manage it until you’re ready to take over!

Canonical URLs

Last year Google, Microsoft, Ask and Yahoo announced the support for Canonical Links in an attempt to help alleviate duplicate urls on sites. This will help prevent indexing of multiple urls that point to the same page.

The syntax is rather simple:

…should be specified in the HEAD section as…

<link rel=”canonical” href=”” />

This simply tells the search engines that the preferred location for the URL is

Instead of…

If you view any SoftLayer web page on the corporate website, you can see canonical URLs in action.

Canonical URL

Why would I need to utilize Canonical Urls?

Good question and here’s why…

The reasons behind the need for canonical urls are simply to help webmasters eliminate self-created duplicate content. Repeat after me: Duplicate content is BAD!

Interested in learning more about Canonical Urls?

Joachim Kupke, from Google, created a lovely slide show with all the information you could want about Canonical Links.
