Best Practices of Infrastructure as Code

Best Practices of Infrastructure as Code

In the traditional system, managing IT infrastructure is a tiresome and time-consuming task. Here, everything needs to manage manually, and there is a lot of room for errors. To remove these problems, businesses are using modern technology- Infrastructure as Code (IaC). Infrastructure as Code is one of the best managing IT infrastructure processes to deliver reliable, efficient, and quality software. The whole process works in an automated system to make it faster and easier.

Top best practices of IaC

IaC is an automated process that helps DevOps teams to deliver quality products in the shortest possible time. Here are four IaC best practices to get the most out of it:

1.   Practice of use definition files

The key practice of IaC is the use of definition files and codifying the whole process. Teams need to define all the configuration files. It includes templates, chef recipes, Ansible playbooks, or any other tools members are using. These configuration files are proof of infrastructure specifications. It also describes which cloud components the teams are using, how they relate them with others, and how the whole process is configured. It also helps to secure the system.

2.      Test, CI, and CD

CI/CD is a great way to manage all the code changes. As it is an automated process, it auto-completes all the tasks, including finding errors, sending alerts to the teams, solving them, and pushing them into production. Testing in every stage helps to find the errors in real-time. Thus developers can solve the problem before it becomes a huge issue. Not only errors but also security needs to be tested at every stage. Genuinely it is high performing and useful for the development teams. It is one of the best practices that automated testing can offer infrastructure teams from software development.

3.   Make small changes & continuous availability 

Small changes are easier to make, test, and use. It ensures that the software is reliable. When something goes wrong, finding bugs and solving them is more manageable in small parts. It also ensures that small problems are not overlooked. It also motivates the workers as it is less time and energy-consuming. Designers need to be careful to include configuration, log files, etc., while widening the data’s definition. Sometimes servers may show errors or get disappeared. To solve this problem, they need to start a new server and continue the service quickly. In this practice there, we need to make sure about zero downtime with continuous keep going services. 

4. Self-documentation

IT teams need to continuously monitor the system to ensure the documents are relevant, useful, and accurate. To reduce this problem, members sometimes make their scripts to make the process easier. IaC helps to capture the actual implemented process in the scripts and definition files. Members need to ensure that the documentation is close to the Code.

IaC is a beneficial process for IT businesses. It ensures consistency, speeds up the deployment, makes the works simple and easy. To get all these benefits, businesses need to consider the best practices of Infrastructure as Code.
