We as humans need contrast, without which we cannot perceive. Because of this, to show something in a good light, something has to be made the villain. This book is about being pragmatic when looking at the cloud. I thank God for the perspective, and my familymy mother, father, sisters and my niece, Aaryawho helped me see it. I am thankful to each and every person who I meet and learn from.

Preface

The book takes us on a journey of architecting, building, and operating a hybrid cloud while taking a very pragmatic approach towards it. The book starts by defining the different demographics of the cloud and the different use cases that need to be solved. It then introduces two modes of building a hybrid cloud, with the CMP and the other with containersalong with the use cases that each of them addresses. The book finally drops into operational mode with topics such as DevOps, monitoring, and security considerations in the hybrid cloud.
