Transforming an application from monolith to microservices-based architecture can be daunting, and knowing where to start can be difficult. Unsurprisingly, organizations are breaking away from monolithic architectures and moving toward event-driven microservices. Migration is time-consuming and involved. create a microservice; 2.

This begins not only in designing the algorithm or coming out with efficient and robust architecture but right onto the choice of programming language.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

Five-nines availability: The ultimate benchmark of system availability. They also need a way to track all the services running on their distributed architectures, from multicloud environments to the edge. But is five nines availability attainable? Each decimal point closer to 100 equals higher uptime. What is always-on infrastructure?

When planning your database HA architecture, the size of your company is a great place to start to assess your needs. This base architecture keeps the database available for your applications in case the primary node goes down, whether that involves automatic failover in case of a disaster or planned switchover during a maintenance window.
