Infrastructure as code (IaC) is a method of managing and provisioning IT infrastructure through the use of code and automation. Instead of manually configuring and provisioning servers, storage, and other resources, IaC allows you to define and manage your infrastructure using code, in the same way you would manage application code. This allows for greater consistency, repeatability, and scalability, as well as easier collaboration and version control.
IaC allows organizations to manage and provision their infrastructure in a more automated, consistent, and scalable way. By using code to define and manage their infrastructure, organizations can improve collaboration, reduce errors, and increase agility in responding to changing business needs.
These tools, such as Ansible, Puppet, and Chef, allow you to define the desired state of your infrastructure using code, and then automatically provision and configure resources to match that state.
Many cloud providers, such as Amazon Web Services (AWS) and Microsoft Azure, offer their own IaC tools, such as AWS CloudFormation and Azure Resource Manager (ARM) templates. These tools allow you to provision and manage cloud resources using code.
Containerization technologies, such as Docker and Kubernetes, allow you to package and deploy applications and their dependencies as containers. This allows for greater consistency and portability across different environments, and can also be managed using IaC tools.
Platforms like AWS, Azure, and Google Cloud provide a way of provisioning resources in an automated and programmatic way, this allows you to define your infrastructure using code and provision it with just a few lines of code.
