Hey Techies! Welcome to this blog
In this blog, we are going to start with Understanding Infrastructure as Code and Configuration Management
Understanding Infrastructure as Code
Infrastructure as code (IaC) means to manage your IT infrastructure using configuration files.
Infrastructure as code is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
Understanding Configuration Management
Configuration management (CM) refers to a process for maintaining computer systems, servers, and software in a desired, consistent state.
On the other hand, CM is the practice of automating the configuration and management of software applications, operating systems, and servers. CM tools help teams automate the installation and configuration of software packages, enforce security policies, and manage system settings.

Differences Between IaC and Configuration Management
While IaC focuses on defining and provisioning infrastructure, Configuration Management deals with maintaining the desired state of that infrastructure over time.
Scope:
IaC: Primarily concerned with the provisioning of infrastructure elements such as servers, networks, and storage.
Config Management: Focuses on ensuring that the configuration of systems and applications remains in the desired state.
Timing:
IaC: Typically executed during the initial setup and deployment of infrastructure.
Config Management: Ongoing process, ensuring continuous alignment with the desired state.
Examples:
IaC: Tools like Terraform and AWS CloudFormation are popular choices for defining and provisioning infrastructure.
Config Management: Ansible and Puppet excel in maintaining and configuring the state of servers and applications.
What are most common IaC and Config management Tools?
Some common Infrastructure as code tools include:
1)Terraform: A popular IaC tool that enables teams to manage infrastructure resources such as servers, networks, and storage in a declarative way using a simple language called HashiCorp Configuration Language (HCL).
2)Pulumi - A tool for creating, deploying, and managing infrastructure on any cloud using your favorite languages.
3)AWS CloudFormation: A service provided by Amazon Web Services (AWS) that enables teams to define and manage infrastructure resources as code using templates. CloudFormation supports several AWS services and enables teams to create and manage complex architectures.
4)Google Cloud Deployment Manager: A service provided by Google Cloud Platform (GCP) that enables teams to define and manage GCP resources as code using YAML or JSON templates.
5)Azure Resource Manager: A service provided by Microsoft Azure that enables teams to manage infrastructure resources using JSON templates.
Some common Configuration Management tools include:
1)Ansible: A popular CM tool that enables teams to automate the configuration and management of software applications. Ansible uses a simple language called YAML to define configurations and supports several operating systems and cloud providers.
2)Chef - A configuration management tool that automates the deployment, configuration, and management of software.
3)Puppet - A configuration management tool that helps automate the management of infrastructure, applications, and compliance.
4)SaltStack - A tool that automates the configuration and management of software applications, operating systems, and servers.
IaC and CM are complementary concepts that help teams automate and manage their IT infrastructure more efficiently. While IaC focuses on the infrastructure layer, CM focuses on the application layer.
Most preferred tool
For Iac - Terraform
For CM - Ansible
