Right now there are millions of virtual machines running on Linux servers powering public and private clouds, both large and small. If you need to understand how Linux server virtualization works, this course should be your first stop.
Linux server virtualization is often associated with hyper-scale deployments like Amazon's AWS and their cloud clients like Netflix, NASA, and Airbnb, but it can also help effectively scale operations of all shapes
and sizes. The problem is that virtualization comes with a very steep learning curve, and just figuring out which tools you should be using can sometimes be harder than figuring out how to use them. This course, Linux Server Virtualization, will introduce the key principles and technologies driving the virtualization movement on Linux, covering both hypervisor and container virtualization solutions like Xen, KVM, VirtualBox, LXC. (Note, however, that you won't cover vSphere's ESXi or Microsoft's Hyper-V.) Using only freely available software that's compatible with just about any PC you might be running, you will learn how to actually install hypervisors and container managers and launch your own virtual machines. When you're done, you should be able to confidently select the best tool for your project and have a useful practical background on which to build.
