Chapter 4. Scalability and Performance
A production-ready microservice is scalable and performant. A scalable, performant microservice is one that is driven by efficiency, one that can not only handle a large number of tasks or requests at the same time, but can handle them efficiently and is prepared for tasks or requests to increase in the future. In this chapter, the essential components of microservice scalability and performance are covered, including understanding the qualitative and quantitative growth scales, hardware efficiency, identification of resource requirements and bottlenecks, capacity awareness and planning, scalable handling of traffic, the scaling of dependencies, task handling and processing, and scalable data storage.
Principles of Microservice Scalability and Performance
Efficiency is of the utmost importance in real-world, large-scale distributed systems architecture, and microservice ecosystems are no exception to this rule. It’s easy to quantify the efficiency of a single system (like a monolithic application), but evaluating the efficiency and achieving greater efficiency in a large ecosystem of microservices, where tasks are sharded out between hundreds (if not thousands) of small services, is incredibly difficult. It’s also bounded by the laws of computer architecture and distributed systems, which place limits on the efficiency of large-scale, complex distributed systems: the more distributed your system, and the more microservices you have in place ...
