OVERVIEW:-
Configuration management is a process for maintaining computer systems, servers, and software in a desired, consistent state. It’s a way to make sure that a system performs as it’s expected to as changes are made over time. And to automate this process Configuration Management Tools are used such as Ansible and Terraform.
Description:
Ansible: Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy and maintain. Automate everything from code deployment to network configuration to cloud management, in a language that approaches plain English, using SSH, with no agents to install on remote systems.
Terraform: HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle.

Training Partners
They laugh at me because I am different, I laugh at them because they are all the same
95 percent Of students say they are better prepared to maximize the value of Red Hat products after training
The person with the certification is
