Infrastructure as Code (IaC) manages IT infrastructure through configuration files, allowing teams to automate and standardize deployments rather than manual processes. In IaC, administrators define infrastructure needs—like servers, networks, and storage—using code, transforming infrastructure management into a process similar to software development (Microsoft, n.d.).
One of IaC’s core benefits is consistency. With every piece of infrastructure described in the code, deployments across environments, such as development, testing, and production, remain consistent. This approach reduces “configuration drift,” which often results from manual changes that complicate troubleshooting and system management over time. When environments match in configuration, applications become more reliable and supportable (Red Hat, n.d.).
IaC also enhances efficiency and speed. With tools like Terraform, Ansible, or AWS CloudFormation, IaC enables quick infrastructure deployment and on-demand scaling. Automated deployments reduce setup time and minimize human error, allowing faster, more reliable updates. This adaptability improves cost efficiency as resources can be scaled up or down according to demand, optimizing infrastructure expenses (HashiCorp, n.d.).
Furthermore, IaC fosters collaboration by allowing infrastructure configurations to be stored and versioned in repositories, similar to software code. Teams can track changes, roll back to previous configurations if needed, and test updates before applying them to production. By treating infrastructure as code, IaC promotes faster iteration, fewer errors, and greater scalability, aligning IT practices with today’s demand for agility (Amazon Web Services [AWS], n.d.).

A "wrap-up" of my Blogging experience:
- What did you find enjoyable or not about this assignment?
- I enjoy the creative writing involved in making these posts.
- Was it helpful to you in your current job?
- My current job title is "Principal Systems Engineer," and I've been in IT for 40 years. No, not really.
- Can you see yourself Blogging in the future when it isn't required for an assignment?
- Yes, I can. Researching a subject and creating something people will want to read is fun.
- Can you see this ability as desirable for a company, giving you more weapons in your arsenal and making you a more attractive hire?
- No, not at all. No company has ever asked me to produce any writings other than technical documentation.
