Chapter 5. DevOps
Developing, testing, and deploying cloud native applications differs significantly from traditional development and operations practices. In this chapter, you learn the fundamentals of DevOps along with the proven practices, including all of the benefits and challenges of developing, testing, and operating cloud native applications. Additionally, we cover designing cloud native applications with operations and rapid, reliable development processes in mind. Most concepts and patterns explained in this chapter are applicable to both containerized services and functions. When this is not the case, we explicitly call out the differences.
What Is DevOps?
DevOps is a broad concept that encompasses multiple aspects of collaboration and communication between software developers and other IT professionals.
