RedHat Expert Session

The session organized by Mr. Vimal Daga Sir and LinuxWorld Informatics Pvt Ltd., on 28th December demonstrating the Industry Use-Cases of Ansible, by RedHat Officials Mr. Sreejith Anujan and Mr. Arun Eapen.

In this wonderful industry level demonstration, We learned about how Ansible is used in the Enterprises. A live demonstration of Provisioning an Instance in AWS cloud was cleanly demonstrated. And not only that, we also connected to notification apps with the help of Ansible Tower and developed a workflow.

In this workflow, we first launched an OS in Oracle cloud, and then added a Slack notifier which notifies every task done while the playbook is launched and is being run. We also added a “Approve or Deny” prompt while going for the CI part of this CI/CD demonstration.

In this Session, we have learned the following things:

1. Automation is the process to do some work with very little or no manual interaction. It can help an Enterprise to not repeat very tedious/complicated tasks.
2. We can use Automation to automate many tasks such as provisioning an OS/instances/container. We can configure some instances as webservers, some system as Load Balancer, configure a database server and many more.
3. Scaling is a must in today’s world, because at anytime the load could increase and we may need some additional servers to have seem-less connectivity, etc.
4. Ansible Tower is kind of a WebApp of Ansible engine with quite a few additional features introduced by Redhat. It can solve the challenge of running multiple playbooks one after the other. It can have workflow execution, and it can be clustered and can have multiple controller nodes.
5. Job Template is simply a playbook which we normally write in YAML
6. We can provision an instance in any cloud with credentials feature of Ansible Tower. The notifications can be passed to any Messaging app(modern chat apps) using the tokens provided by the concerned chat/notification service. Thankyou Mr. Vimal Daga Sir and LinuxWorld Informatics Pvt. Ltd. for planning this wonderful industry use cases demonstration.

We would love to have many such sessions in the future as it makes us hand-ready for Industries and Enterprises.
