SoftLayer Private Clouds are officially live, and that means you can now order and provision your very own private cloud infrastructure on Citrix CloudPlatform quickly and easily. Chief Scientist Nathan Day introduced private clouds on the blog when it was announced at Cloud Expo East, and CTO Duke Skarda followed up with an explanation of the architecture powering SoftLayer Private Clouds. The most amazing claim: You can order a private cloud infrastructure and spin up its first virtual machines in a matter of hours rather than days, weeks or months.
If you’ve ever looked at building your own private cloud in the past, the “days, weeks or months” timeline isn’t very surprising — you have to get the hardware provisioned, the software installed and the network configured … and it all has to work together. Hearing that SoftLayer Private Clouds can be provisioned in “hours” probably seems too good to be true to administrators who have tried building a private cloud in the past, so I thought I’d put it to the test by ordering a private cloud and documenting the experience.
When we started the order process, part of our work is already done for us:
To guarantee peak performance of the CloudPlatform management server, SoftLayer selected the hardware for us: A single processor quad core Xeon 5620 server with 6GB RAM, GigE, and two 2.0TB SATA II HDDs in RAID1. With the management server selected, our only task was choosing our host server and where we wanted the first zone (host server and management server) to be installed:
For our host server, we opted for a dual processor quad core Xeon 5504 with the default specs, and we decided to spin it up in DAL05. We added (and justified) a block of 16 secondary IP addresses for our first zone, and we submitted the order. The time: 9:38am.
At this point, it would be easy for us to game the system to shave off a few minutes from the provisioning process by manually approving the order we just placed (since we have access to the order queue), but we stayed true to the experiment and let it be approved as it normally would be. We didn’t have to wait long:
At 9:42am, our order was approved, and the pressure was on. How long would it take before we were able to log into the CloudStack portal to create a virtual machine? I’d walked over to Phil’s desk 12 minutes ago, and we still had to get two physical servers online and configured to work with each other on CloudPlatform. Luckily, the automated provisioning process took on a the brunt of that pressure.
Both server orders were sent to the data center, and the provisioning system selected two pieces of hardware that best matched what we needed. Our exact configurations weren’t available, so a SBT in the data center was dispatched to make the appropriate hardware changes to meet our needs, and the automated system kicked into high gear. IP addresses were assigned to the management and host servers, and we were able to monitor each server’s progress in the customer portal. The hardware was tested and prepared for OS install, and when it was ready, the base operating systems were loaded — CentOS 6 on the management server and Citrix XenServer 6 on the host server. After CentOS 6 finished provisioning on the management server, CloudStack was installed. Then we got an email:
At 11:24am, less than two hours from when I walked over to Phil’s desk, we had two servers online and configured with CloudStack, and we were ready to provision our first virtual machines in our private cloud environment.
We log into CloudStack and added our first instance:
We configured our new instance in a few clicks, and we clicked “Launch VM” at 11:38am. It came online in just over 3 minutes (11:42am):
I got from “walking to Phil’s desk” to having a multi-server private cloud infrastructure running a VM in exactly two hours and twelve minutes. For fun, I created a second VM on the host server, and it was provisioned in 31.7 seconds. It’s safe to say that the claim that SoftLayer takes “hours” to provision a private cloud has officially been confirmed, but we thought it would be fun to add one more wrinkle to the system: What if we wanted to add another host server in a different data center?
From the “Hardware” tab in the SoftLayer portal, we selected “Add Zone” to from the “Actions” in the “Private Clouds” section, and we chose a host server with four portable IP addresses in WDC01. The zone was created, and the host server went through the same hardware provisioning process that our initial deployment went through, and our new host server was online in < 2 hours. We jumped into CloudStack, and the new zone was created with our host server ready to provision VMs in Washington, D.C.
Given how quick the instances were spinning up in the first zone, we timed a few in the second zone … The first instance was online in about 4 minutes, and the second was running in 26.8 seconds.
By the time I went out for a late lunch at 1:30pm, we’d spun up a new private cloud infrastructure with geographically dispersed zones that launched new cloud instances in under 30 seconds. Not bad.
Don’t take my word for it, though … Order a SoftLayer Private Cloud and see for yourself.
