Microservices based product's scalability, performance, and efficiency is an important goal for every company. Even when the number of simultaneous requests to the microservice grows exponentially, there should be no loss to the response time. An efficiently architected system should scale up or down based on the number of requests.

 

Evaluating performance and scalability becomes complex in a distributed system as each microservice runs in an isolated environment (containers), and they communicate through messaging protocols. Testing every microservice individually and the whole system is meeting expected performance metrics. We calculate growth scales (qualitative and quantitative) to establish sizing guidelines. We also make sure the entire system is fault-tolerant so that there is no loss of service for customers.
