In this chapter, we covered a lot of topics. We introduced AWS as a cloud solution and did some cool things with it – we converted our virtual machine so that we can run in it, and made sure that everything works. Then we moved to Eucalyptus, to check how we can use it as a management application for our local cloud environment, and how to use it to extend our existing environment to AWS.
The next chapter takes us into the world of monitoring KVM virtualization by using the ELK stack. It's a hugely important topic, especially as companies and infrastructures grow in size – you just can't keep up with the organic growth of IT services by manually monitoring all possible services. The ELK stack will help you with that – just how much, you'll learn in the next chapter.
