Background
It's a world of microservices. Such applications or microservices are required to store data temporarily with frequent and super quick access to avoid disk IO operations using Redis-like in-memory databases. These applications have multiple in-memory database clusters to handle huge amounts of traffic and to avoid request failures. To access this data quickly, applications are required to have the preconfigured, established pooled connections ready for service from the applications.
Problem Statement
Applications built for resiliency have backup options in case of application or infrastructure failures. In-memory database clusters that exist in different data centers on different servers allow for backup connectivity in case of data center or server issues.
