Chapter 9: Designing a Resilient Platform for Cloud Migration

A cloud migration solution should ensure business continuity (BC). Therefore, resiliency is one of the fundamental characteristics of the cloud. Resiliency enforces high availability (HA), auto-scaling, workload backup and restore, failover, and disaster recovery (DR) to ensure the ecosystem is fault-tolerant and BC is verified in the target state after cloud migration. The core characteristics of resiliency are noted here:

• HA is achieved when the organization’s data, system, and environment are available to end users.
• Backup and restore focus on copying data, systems, and environment multiple times and restoring them to the corresponding system to ensure their availability for recovery.
• DR ensures the built-in redundancy of the system with defined failover at the time of failure.

In this chapter, we will discuss the following topics:

• Planning to build a resilient platform
• Implementing...
