In the IT industry, several Infrastructure as Code (IaC) tools are commonly used to automate the provisioning, configuration, and management of infrastructure resources. Some of the most popular IaC tools include:
Terraform: Terraform, developed by HashiCorp, is one of the most widely adopted IaC tools. It allows users to define infrastructure as code using a declarative configuration language called HashiCorp Configuration Language (HCL) or JSON. Terraform supports multiple cloud providers (such as AWS, Azure, Google Cloud Platform) and on-premises infrastructure.
AWS CloudFormation: AWS CloudFormation is a native infrastructure automation service provided by Amazon Web Services (AWS). It allows users to define and manage AWS infrastructure using JSON or YAML templates. CloudFormation enables the creation and provisioning of resources in AWS in a repeatable and consistent manner.
Azure Resource Manager (ARM) Templates: Azure Resource Manager Templates are used for defining and deploying Azure infrastructure resources in a declarative manner. These templates are JSON files that describe the desired state of Azure resources, including virtual machines, storage accounts, networking components, and more.
Google Cloud Deployment Manager: Google Cloud Deployment Manager is a service provided by Google Cloud Platform (GCP) for automating the creation and management of GCP infrastructure resources. It uses YAML or Jinja2 templates to define the desired state of resources and supports various GCP services.
Ansible: Ansible is a popular configuration management and automation tool that can also be used for infrastructure provisioning. It uses YAML-based playbooks to define tasks and configurations, making it easy to automate infrastructure deployment and management across diverse environments, including on-premises and cloud.
Pulumi: Pulumi is an open-source infrastructure as code platform that allows users to define infrastructure using familiar programming languages such as JavaScript, Python, TypeScript, and Go. It supports multiple cloud providers and enables infrastructure automation with the flexibility and expressiveness of general-purpose programming languages.
Chef: Chef is a configuration management tool that automates the deployment and management of infrastructure using a domain-specific language (DSL) called Chef Infra. It allows users to define infrastructure as code and manage configuration drift across servers and cloud environments.
SaltStack: SaltStack is another configuration management and automation tool that can be used for infrastructure provisioning and management. It uses YAML-based state files and a flexible remote execution framework to automate tasks and enforce desired states across infrastructure.
These are some of the most commonly used Infrastructure as Code tools in the IT industry. The choice of tool depends on factors such as the specific requirements of the project, the preferred cloud provider or infrastructure platform, the expertise of the team, and individual preferences.
