Infrastructure As Code (IaC) is a method where scripts automate infrastructure and configuration management (networks, virtual machines, load balancers, and connection topology) in a descriptive model that uses the same versioning that the DevOps team uses for source code. Like the principle that the same source code generates the same binary (Application), generates an IaC model in the same environment each time it is being used. IaC is an important DevOps practice and is used in the context of continuous delivery.
However, IaC is more than just documentation, as the method is also an important part of version control for any modern software development. IaC makes it possible to roll back previous versions or deliver clean copies of the code base, which is especially an advantage when used in an iterative environment. IaC can even help identify problems before they emerge via continuous integration driving.
Imagine the possibilities of building your infrastructure with a tool that can do it for you. There are a number of different IaC tools that can codify and deliver the infrastructure, saving time in manual configuration tasks. One can use these tools to build playbooks as templates or scripts that describe the desired state of a given system. All without having to spend many hours configuring them manually. IaC can therefore automate time-consuming tasks that would otherwise have to be done manually, which is one of the reasons why developers love IaC, as it makes their job easier. For example, when provisioning and deploying servers, which is usually not the developers' favorite task. Furthermore, you can save money on hosting costs because they require fewer server resources than manual configuration.
Cegal and IaC
At Cegal, we have developed our own Automation platform to deliver Cloud Products by Infrastructure as Code. The use of IaC helps us guarantee a standardized delivery with great quality – every time. This enables our customers with national, regional, or global footprints to be faster, more efficient, and more precise. IaC is a key factor for quality when extending our customers from Private Cloud to Public Cloud, and our method for delivery to all cloud platforms.
