- 4. DEPLOY APPS. MANAGE SYSTEMS. CRUSH COMPLEXITY. WHAT IS ANSIBLE • Ansible was originally written by Michael DeHaan, the creator of the Cobbler provisioning application. • Ansible is an open source configuration management and orchestration utility. It can automate and standardize the configuration of remote hosts and virtual machines. Its orchestration functionality allows Ansible to coordinate the launch and graceful shutdown of multitiered applications. Because of this, Ansible can perform rolling updates of multiple systems in a way that results in zero downtime. • Ansible, Inc. (originally AnsibleWorks, Inc.) was the company set up to commercially support and sponsor Ansible. Later it was acquired by Red Hat in October 2015.
- 5. IT’S SIMPLE POWERFUL AGENTLESS WHY ANSIBLE? • Everyone hates repetitive work - Ansible Loves It. Ansible is a simple automation language that can perfectly describe an IT application infrastructure. It’s easy-to- learn, self-documenting, and doesn’t require a grad-level computer science degree to read. Automation shouldn’t be more complex than the tasks it’s replacing. • Complexity kills productivity - Every business is a digital business. Delivering your applications faster helps you win. That requires a lot of manual effort and complicated coordination. We need a tool to drive complexity out of our environments and accelerate DevOps initiatives.

- 10. ANSIBLE MODULES • Modules are programs that Ansible uses to perform operations on managed hosts. They are ready-to- use tools designed to perform specific operations. Modules can be executed from the ansible command line or used in playbooks to execute tasks. When run, modules are copied to the managed host and executed there. • Three Type of Modules 1.Core modules are included with Ansible and are written and maintained by the Ansible development team. Core modules are the most important modules and are used for common administration tasks. 2.Extras modules are currently included with Ansible but may be promoted to core or shipped separately in the future. They are generally not maintained by the Ansible team but by the community. 3.Custom modules are modules developed by end users and not shipped by Ansible. If a module does not already exist for a task, an administrator can write a new module to implement it.
- 12. PLAYBOOKS • Playbooks are text files written in YAML format. • Ansible playbooks also contain list of plays, where each play serves to define a set of operations to perform on a specific set of managed hosts. These operations are called tasks, and the managed hosts are referred to as hosts. Tasks are performed by invoking Ansible modules and passing them the necessary arguments to accomplish the desired operation.
