Infrastructure as Code

Infrastructure as Code (IaC) has become an integral part of various careers in ICT, particularly in relation to the cloud. Software like Kubernetes, Docker, Chef, and Puppet lead the charge in utilizing IaC in daily operations. The HashiCorp suite fits perfectly into this genre. Tools like Terraform, Vault, and Vagrant can be used to create fully automated environments for realizing automation. In this chapter, we will introduce the basic principles of Infrastructure as Code from a theoretical perspective. This is fundamental for better design and implementing the automation in real applications.
