Microservices From Day One
Build robust and scalable software from the start

Authors: Cloves Carneiro Jr., Tim Schmelmer



Defines what microservices are and how they can benefit your business

Sets out best practices to follow when implementing microservices

Shows how to test, launch, and optimize microservices

Learn what a microservices architecture is, its advantages, and why you should consider using one when starting a new application. The book describes how taking a microservices approach from the start helps avoid the complexity and expense of moving to a service-oriented approach after applications reach a critical code base size or traffic load.

Microservices from Day One discusses many of the decisions you face when adopting a service-oriented approach and defines a set of rules to follow for easily adopting microservices. The book provides simple guidelines and tips for dividing a problem domain into services. It also describes best practices for documenting and generating APIs and client libraries, testing applications with service dependencies, optimizing services for client performance, and much more. Throughout the book, you will follow the development of a sample project to see how to apply the best practices described.

What You Will Learn:
• Apply guidelines and best practices for developing projects that use microservices
• Define a practical microservices architecture at the beginning of a project that allows for fast development
• Define and build APIs based on real-world best practices
• Build services that easily scale by using tools available in most programming languages
• Test applications in a distributed environment
