Up until now, we have focused on AWS as a cloud provider. Of course, there are other providers that offer similar services, the two biggest being the Microsoft Azure Cloud and the Google Cloud Platform. Besides these, there are many other providers that also offer IaaS solutions, more often than not based on the open source platform OpenStack.
All cloud providers employ similar concepts, so if you have experience with one of them, you will probably find your way around others. For this reason, we decided not to cover each of them in depth within this book, but instead focus on AWS and give you a short outlook on other providers and how they are different.
