We will discuss OpenStack as a microservice application. What you will have to face if you want to launch your own cloud based on OpenStack. What problems arise when you deploy such a large and complex system, how to maintain it, and provide a highly available cloud for your client. And how Kubernetes can (or cannot) help with this. In this talk, based on experience, Vadim will tell you about the tricks, the most common mistakes, and how they can be solved.
