Rackspace delivers OpenStack private clouds as-a-service, architected like a public cloud and designed for scale and service availability to any data center in the world. It includes a 99.99% API Uptime SLA.
FlexPod is great for mid to large size companies, where the flexibility and depth of a traditional SAN and high performance servers is required. For smaller companies, it might make more sense to go with a hyper converged solution such as Hyperflex or Nutanix (both of which can still run on Cisco UCS servers, but would not be making use of Netapp storage), to meet the requirements in a smaller footprint.
Need to get an application up and running, then I would say the open stack is a great place to test it out. Why spend time setting things up when you can let them do it for you? Many people also have experience with using Rackspace in some capacity so its an easier learning curve for many people.
KVM control of the blades still requires Java. Avocent is using HTML5 now, and it would be nice if the KVM console for these UCS blades could too.
Price - Like any Cisco product, there are cheaper options. They aren't nearly as fully featured, but at times, it would be nice if UCS could be a bit cheaper.
Being a Cisco shop already it was a natural fit to go with a solution based on their technology. Then add in VMware which we are were already using - that was two out of the three for the FlexPod. Then factor in NetApp's de-duplication technology and flexibility in configuration and options and it's a match made in heaven. Not to say we haven't had some stumbles and some issues but it works and it works well.
I looked into going with Amazon EC2, was very comparable in pricing, services, options, etc. and a bit cheaper too. Why I did not go with Amazon mainly has to do with knowing Rackspace and being familiar with them. It was easier for me to use a Rackspace product then go with Amazon Elastic Compute Cloud
FlexPod has allowed our team to be extremely quick to resopnd to new VM build requests. The amount of RAM, CPU and backplane offered by B series blades allows us to go with very high VM density. The quick deployment of service profile templates also means that when we have to add new hosts, it is done quicker.
FlexPod and the service profile portability (along with VMware) has allowed for full upgrades and migrations from M1/M2 series hardware to M4 hardware without any downtime or outages to the clients. Blades can be moved into new chassis, or service profiles moved to new generation blades, with no impact to the customers' ability to work.
