Flexible virtual infrastructure has supported complex KVM workloads and accelerated SAP-ready hostingFor Rackspace OpenStack security features, we currently opted for ShapeBlue one, which will be installing CloudStack. ShapeBlue is helping us in training. So, we are moving away from Rackspace OpenStack to CloudStack because CloudStack has most of the features that we require, and it is also lightweight. Rackspace OpenStack does not provide that thing. The product has all the things included, you can say like that. But the thing is, if you are a company, if you are a hosting company, you will require at least three to four people with higher expertise to install and get going with Rackspace OpenStack. It is very hard; you have to understand bits and many things about it, how it works. It is not something you just tinker around with. The second thing is we are moving to CloudStack because it comes as just a single package that I can install in a VM and I am done with it. I just need to configure it the first time, and everything, the experience out-of-the-box is very good with CloudStack. But Rackspace OpenStack is very assembled parts, you can say. Would you prefer an assembled PC or would you prefer an HP-provided PC, a branded PC? It depends on you. The main thing about Rackspace OpenStack is that it is totally built on many modules. It is approximately 30 to 40 modules, you can say. You have to learn and understand that, which there is a very steep learning curve. If I am not wrong, there is a very steep learning curve. There is not one way to install Rackspace OpenStack; there are several ways, approximately three to four ways. But it depends on who deployed it. Suppose a person deployed it in a different style; after one or two years, he got changed, and another person comes. He does not know about that style, then it will be very hard to navigate. Currently, Kolla-ansible, which we have, is very hard to navigate for me. Although it is very easy to install, it is very hard to operate because it works on Docker. So, there are too many moving parts. If you say to me, there are too many moving parts, and the visibility is low on that. It is very hard to have any issue with it. It is a very stable product.
