Spring Cloud provides the support essential for the deployment of microservices at scale. In order to get the full power of a cloud-like environment, the microservices instances should also be capable of scaling out and shrinking automatically based on traffic patterns.
This chapter will detail out how to make microservices elastically grow and shrink by effectively using the actuator data collected from Spring Boot microservices to control the deployment topology by implementing a simple life cycle manager.
By the end of this chapter, you will learn about the following topics:
This chapter will cover the Application Lifecycle Management capability in the microservices capability model discussed in Chapter 3, Applying Microservices Concepts, highlighted in the following diagram:
We will see a basic version of the life cycle manager in this chapter, which will be enhanced in later chapters.
