For our project, we create infra like S3 buckets and our networks and servers. Like these, there are so many requirements in my project. Previously we were working with different services based on the cloud platform. Suppose I am creating infrastructure in AWS; we just used CloudFormation, like in Azure We used Azure Resource Manager and GCP; we used Google Cloud Deployment Manager...like that we were working on our project. but right now in my latest project, we implemented a new style infra creation  using only one software tool across all the cloud platforms like AWS, Azure, and GCP. The software tool name is Terraform. terraform is a infrastructure creation software tool which we are using in my current project With the help of this Terraform, we are creating our project infrastructure, like S3 buckets, networks, services, and so on. Previously we were spending a lot of time to crate infrastructure by using respective cloud services ...instead of using all these services, we ju...

 1. Copy module: Copies files from the control machine to the target host. like deploying a configuration file. 2. Package module: Irrespective of the operating system, it selects the appropriate package module and installs, upgrades, or removes software. 3. Service module: manages services like start, stop, restart, enable 4. User module: Manages user accounts like create, deleting, and modifying user accounts 5. yum/apt module: Install or remove upgrade packages like Debian-based and red hat based environments.

How Ansible Modules Work Execution Flow: whenever  y ou execute a playbook or run an ad-hoc command 2. Ansible copies the module to the target host 3. The module executes on the remote system 4. Results are returned to the Ansible control node
