Database provisioning and Infrastructure as Code

As we discussed in the previous chapter, Infrastructure as Code (IaC) is a key DevOps practice that involves managing and provisioning data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This approach has several advantages, including speed, repeatability, scalability, and reduced human error.

IaC is highly relevant to DevOps DBAs because it can automate many of the tasks involved in setting up and managing databases. For example, instead of manually installing a database server, configuring it, and creating databases and tables, a DevOps DBA can write a script that does all this automatically. The script can be version controlled, tested, and run multiple times to create identical environments.
