 # Ansible
 
-Ansible is an open-source automation tool that simplifies complex software management, deployment, and configuration processes. It helps automate day-to-day IT tasks by defining them as simple, human-readable YAML files (called 'playbooks') that can be shared and understood easily by the whole team.
+Ansible is an open-source configuration management, application deployment and provisioning tool that uses its own declarative language in YAML. Ansible is agentless, meaning you only need remote connections via SSH or Windows Remote Management via Powershell in order to function

 # Checkpoint
 
-> —— In Progress ——
+Now that you have learnt ansible, you can use it to automate the deployment of your application. 
+
+A task for you at this point would be to automate the steps that you manually performed earlier when setting up the EC2 instance i.e. SSH into the server, install Node.js, Git, PostgreSQL, Running the application etc. Write an ansible playbook that automates these and see if you can spin up a new EC2 instance without SSHing into it and manually installing all the dependencies.

 # Terraform
 
-Terraform is an open-source infrastructure as code (IaC) tool that allows you to define, provision, and manage cloud infrastructure in a declarative manner. It is developed by HashiCorp and is written in the Go programming language. Terraform supports multiple cloud providers such as AWS, Google Cloud, Microsoft Azure, and many others. It uses a configuration language called HashiCorp Configuration Language (HCL) to write infrastructure definitions, and it maintains the state of your infrastructure in a state file.
+Terraform is an extremely popular open source Infrastructure as Code (IaC) tool that can be used with many different cloud and service provider APIs. Terraform focuses on an immutable approach to infrastructure, with a terraform state file center to tracking the status of your real world infrastructure.

 # Checkpoint
 
-> —— In Progress ——
+If you remember, earlier in the roadmap, you manually logged into the AWS console and had to setup the services. Now that you know terraform, go ahead and automate the process of creating the infrastructure for your application using terraform and with that your deployments will be fully automated i.e., you should have:
+
+- Infrastructure setup using terraform
+- Provisioning using Ansible
+- CI/CD using GitHub Actions
+- Monitoring using Monit
+
+And that is it! You have successfully completed the roadmap and are now a full-stack developer. Congratulations! 🎉
