What Is IaC?
Infrastructure as Code (IaC) refers to the technology and processes used to manage and provision infrastructure with software instead of manual operations. First, it has replaced the act of racking physical servers in a data center, and secondly, it has allowed for manually building servers using software programming in the cloud. Infrastructure as Code tools and processes allow engineers to quickly build and destroy servers on cloud platforms using automation tools. The trick now is to make those pieces of software as secure as the rest of the network, applications, and databases.
The most common Infrastructure-as-Code tools are Ansible, Terraform, CloudFormation from AWS, and Pulumi. Terraform is the open-source framework by HashiCorp. More than any other framework, Terraform has made Infrastructure as Code limitlessly customizable and accessible, thus paving the way for the surrounding IaC ecosystem.
A significant portion of technology has to be spent focused on software engineering infrastructure. The blend of workloads, applications, and broad access to resources paired with consistent and secure delivery methods used to support software development is vital. How technology is used is as equally important as to the methods and processes for creating and delivering software code.
