Infrastructure as Code (IaC): Benefits Include Better Security and Consistent Configurations
Historically, Infrastructure as Code (IaC) has seen many iterations, starting with configuration management tools such as Ansible, Salt, Puppet, Chef and CFEngine.
Newer tooling like?Cloudformation?and?Terraform?take a declarative approach and focus on the actual provisioning of resources, as opposed to the configuration of existing ones.
This newest generation of IaC tools focuses on using the capabilities of existing imperative programming languages. Terraform and AWS both provide Cloud Development Kits (CDKs).
Terraform has become especially popular as an Infrastructure as Code tool that allows engineers to define their software infrastructure in code.
Experts in this field contend that the ability to provision infrastructure this way is a powerful abstraction that enables managing large distributed systems at scale.
Additional benefits of Infrastructure as code include consistent configurations.
Repeatability is core to the nature of Infrastructure as Code; the ability to spin up pre-configured environments every time ensures consistency across the board. In addition to helping eliminate deviations and reduce errors, ensuring consistent configurations also avoids incompatibility issues that would prevent applications from running correctly.
Another major benefit: Stronger security and faster recovery.

The benefits of Infrastructure as Code security features are connected to the concepts of creating consistency and decreasing risk. Pre-provisioning infrastructure with code creates an opportunity to bake in?security protocols?at the ground level, ensuring that every deployment is as secure as possible without additional layers of review and approval by a gatekeeper.
This is crucial because if changes are made to a company’s security practices, it’s simple to update the coded infrastructure to reflect them companywide. Infrastructure as Code can also factor into recovery plans, although deploying disaster recovery environments in this way can sometimes lead to longer downtimes than other strategies.
