Hybrid Cloud for Architects

By: Alok Shrivastwa

Overview of this book

Hybrid cloud is currently the buzz word in the cloud world. Organizations are planning to adopt hybrid cloud strategy due to its advantages such as untested workloads, cloud-bursting, cloud service brokering and so on. This book will help you understand the dynamics, design principles, and deployment strategies of a Hybrid Cloud. You will start by understanding the concepts of hybrid cloud and the problems it solves as compared to a stand-alone public and private cloud. You will be delving into the different architecture and design of hybrid cloud. The book will then cover advanced concepts such as building a deployment pipeline, containerization strategy, and data storage mechanism. Next up, you will be able to deploy an external CMP to run a Hybrid cloud and integrate it with your OpenStack and AWS environments. You will also understand the strategy for designing a Hybrid Cloud using containerization and work with pre-built solutions like vCloud Air, VMware for AWS, and Azure Stack. Finally, the book will cover security and monitoring related best practices that will help you secure your cloud infrastructure. By the end of the book, you will be in a position to build a hybrid cloud strategy for your organization.

Container orchestration engine 


The following are the major container orchestration engines: 

  • Kubernetes (k8s)
  • Mesos 
  • Swarm 

In this book, we will be dealing with Kubernetes mainly. We expect the following features: 

  • Ability to provision/deprovision containers across multiple hosts
  • Ability to connect storage and network to the containers 
  • Ability to route requests to the containers

Almost all the platforms provide this, however, let's take a look at Kubernetes and how it provides these features. The reason we choose Kubernetes as an example is because it has been adopted more widely than any other competitor on the market, and some cloud providers even support it directly. For example, Azure has an ACE (Azure Container Engine) based on Kubernetes and Red Hat's OpenShift platform uses Kubernetes as the underlying system. 

Kubernetes architecture 

Kubernetes is a system that works on the concept of a cluster. A Kubernetes cluster has two categories of nodes. These are master and worker (a.k.a. minion...
