CHAPTER 12
Linux in the Cloud

CLOUD TECHNOLOGY HAS GREATLY CHANGED the landscape of the computer world. Moving computer resources and applications into a shared network environment changes how many companies do business and provide services to customers.

This chapter introduces the main concepts of just what a cloud is and the role that Linux plays in cloud computing. The chapter starts out by defining what cloud computing is and what the different types of cloud computing environments are. Next is a discussion of how virtualization plays an important role in cloud computing and how that is implemented in Linux.

Following that is an explanation of how containers fit into cloud computing and how they have changed how developers do their jobs. A hot topic in the container world these days is orchestration. The chapter discusses how orchestration is used to manage containers and helps automate deploying them. Finally, the chapter takes a peek at a common use for containers—DevOps.
