Infrastructure as Code, 3rd Edition

Chapter 13. Providing Application Runtime Infrastructure

A Note for Early Release Readers

With Early Release ebooks, you get books in their earliest form—the author’s raw and unedited content as they write—so you can take advantage of these technologies long before the official release of these titles. This will be the 13th chapter of the final book. Please note that the GitHub repo will be made active later on. If you have comments about how we might improve the content and/or examples in this book, or if you notice missing material within this chapter, please reach out to the editor at [e-mail].

The topic of this chapter is application runtime services, which are those services that are directly involved in hosting running workloads. The other services in the platform layer include delivery services and operational services, which are necessary but not directly involved in running the applications. Delivery services are used to create, validate, and deploy changes to software, examples including source code repositories, pipeline services, and deployment services. Operational services are used to manage running applications, including things like monitoring and reporting. ...
