This chapter summarized the design guidelines, best practices, and coding tips that developers will find useful when building RESTful web services. You can freely refer to this chapter while working with the JAX-RS and Jersey frameworks.

This chapter started with tips for designing and developing scalable RESTful web APIs and moved from the design guidelines to REST API optimization techniques such as caching, partial representation, partial update, and asynchronous API calls. It then moved on to discuss the microservice architectural style and its relevance. By now, you should have learned how to build scalable and well-performing RESTful applications by using the JAX-RS and Jersey APIs.
