Infrastructure as Code (IaC)



Infrastructure as Code (IaC) is an approach to managing and provisioning IT infrastructure through the use of code and software development techniques. In other words, it means automating the process of configuring and deploying infrastructure using software tools and programming languages. IaC is the latest trend in IT operations and is fast becoming the preferred approach for managing infrastructure in both small and large organizations.

Benefits of IaC

One of the most significant benefits of IaC is its ability to automate processes, which reduces human error and increases efficiency. With IaC, infrastructure can be deployed quickly and consistently, reducing deployment time and ensuring that environments are configured correctly every time. It also enables teams to collaborate better, as IaC allows for version control and other software development practices that make it easier for teams to work together.

  • Speed: Infrastructure as Code (IaC) tools allow you to create resources much faster compared to manually navigating through multiple screens. For instance, recreating an environment for a critical application due to unforeseen circumstances can take hours if done manually, but an IaC tool can accomplish this in minutes.
  • Consistency: IaC tools enable the creation of identical environments repeatedly, minimizing the risk of errors that can occur when done manually.
  • Traceability: IaC tools require a configuration file to create an environment, allowing for easy tracking and versioning in a source code system like AWS CodeCommit or GitHub. This history can assist fellow developers in reviewing changes.
  • Cost Reduction: Manual creation of resources requires human effort each time. Automation with IaC tools eliminates this need, reducing associated costs.
  • Customizability: IaC tools are customizable, with parameters that can be passed at runtime to tailor them for specific environments. For example, you can launch two instances of an EC2 instance in your development environment and ten in production by passing these values as parameters.
  • Reduced Risk: IaC automation produces consistent results each time, reducing the risk of human error and potential outages due to misconfiguration.
  • Standardization: IaC tools can enforce and standardize security practices and other organizational standards. These can be linked to an approval process, providing visibility into changes in your environment.
  • Self-Documentation: IaC tools self-document, explaining how your infrastructure was created and when changes were made. This eliminates the need for explicit documentation for new team members.

Implementing IaC


Implementing IaC requires a shift in mindset, as it involves treating infrastructure as a software project. This means that infrastructure must be designed, versioned, and tested like any other software. Teams must also adopt DevOps practices to ensure that they can effectively manage IaC. This includes using continuous integration and continuous delivery (CI/CD) pipelines to automate the deployment process, and using tools like Puppet, Chef, and Ansible to manage infrastructure as code.

Infrastructure as Code is the future of IT operations, and its benefits are numerous. By automating infrastructure deployment and management, organizations can achieve greater efficiency, reliability, and scalability. However, implementing IaC requires a shift in mindset and the adoption of DevOps practices. Organizations that embrace IaC will be better positioned to succeed in today’s fast-paced, constantly evolving IT landscape.
