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.

The traditional concepts in monitoring


Monitoring is a problem that has been solved in many different ways for many different levels of stack. Let's take a look at different demographics of monitoring:

  • Availability monitoring (up/down monitoring) 
  • Performance monitoring (time series—CPU, memory, utilization, and so on) 

In the infrastructure side of things, availability monitoring and performance monitoring are both used, but the application side is a little heavy on the performance monitoring as the availability of the application is monitored on the infrastructure level itself by the load balancers and the likes.

The following diagram shows the different protocols that are generally used in monitoring systems of different types:

Availability monitoring 

This is the simplest kind of monitoring, which marks the object that is being monitored as either up or down. This is generally done using several protocols such as ICMP (ICMP_ECHO) and sometimes even TCP and UDP (or enhanced verification on...
