In today's digital world, cloud infrastructure has become a critical part of businesses' IT strategies. As companies continue to rely more on the cloud, the complexity of managing infrastructure increases. There are numerous cloud providers that offer a wide range of remote services. Additionally, to fully complete our infrastructure, we also require additional services beyond the cloud. Small projects can lead to having a large infrastructure, and even though cloud providers offer simple ways to deploy services, it's crucial to track the infrastructure's complexity using Infrastructure as Code. In this article, we will explore the basics of Infrastructure as Code and explain why it is an essential tool for modern cloud infrastructure management.

What is Infrastructure as Code?

Infrastructure as code (IaC) is an approach to managing IT infrastructure in which the infrastructure is defined in a descriptive programming language. This approach has gained popularity in recent years around cloud systems due to its ability to automate the deployment and management of complex infrastructure resources, reduce errors, and increase the speed of software development.

With IaC, you can define and configure resources such as virtual machines, networks, storage, and security groups to be deployed on the cloud using code. This code can be version-controlled, tested, and deployed in the same way as software code. Furthermore, it eases the burden to deploy a secure and reliable infrastructure, since the developers can rely on fully developed templates that have been validated and put together by professionals.

IaC tools typically work by taking your code and translating it into an API call to a cloud provider, which then creates the necessary resources. Changes to the code can be tracked, versioned, and tested, and the deployment process can be automated to ensure that changes are made consistently and with minimal risk. Automating the deployment pipeline streamlines the developer's workflow, enabling them to interact solely with the code to modify the final state. Here's a visual representation.

Advantages of Infrastructure as Code

Infrastructure as Code offers several benefits such as increased speed and efficiency, improved reliability and consistency. By automating the provisioning and management of infrastructure, teams can deploy resources quickly and reliably. Additionally, IaC allows for consistent and repeatable deployments, which can improve reliability and reduce downtime. Fundamentally, it can be broken down into the following aspects:

Documentation - Using IaC automatically gives you the possibility to understand how the infrastructure was configured and ensures that undesired changes can be discovered quickly since all affected resources and their associated configurations are clearly stated in the code. By relying on version control, debugging becomes even more accessible and new developers have the ability to track how it got to that state and idea. This transparency helps not only to identify problems but also to expand and develop the infrastructure.

Modularity - One of the most beautiful benefits of using infrastructure as code is the possibility to fall back on fully developed modules. Modules are reusable pieces of code that encapsulate a set of resources and their associated configurations. They are used in Infrastructure as Code (IaC) to create and manage infrastructure in a modular, scalable, and maintainable way. This not only enhances the ability to map complex relationships more efficiently but also allows us to rely on validated concepts. Creating custom modules enables you even to standardize your workflow and enforce custom safety concepts.

Disaster Recovery - Disasters can strike anytime, and businesses need to be prepared to mitigate their impact. Infrastructure as Code can help with disaster recovery by making it easy to identify what has changed since the disaster occurred. Additionally, by maintaining the infrastructure as code in a version control system, in a worst-case scenario teams can easily revert to a previous working state. This ensures that businesses can quickly resume their operations in the event of a disaster, with minimal downtime or impact on their customers.
