Monolithic software systems employ one large codebase, which includes collections of tools, software development kits, and associated development dependencies. Because monolithic software systems employ one large codebase repository, the service becomes a massive piece of software that is labor-intensive to manage.

The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed. If you are building resilient systems with failover, the control plane that manages failover is often the hardest part of the system to get right.

Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. Therefore, before we attempt to measure our database performance, we should know the system or cloud instance to be tested in detail. Operating System: Ubuntu 22.04
