Ansible: A robust IT automation engine that automates cloud provisioning

In science fiction, the ansible is a device that allows for instantaneous communication over vast distances that are measured in thousands of light-years. In the current IT landscape, the Ansible is an IT automation engine.

On the face of it, the Ansible is extremely simple. Yet it can automate many of the most crucial processes in IT. These include configuration management, cloud provisioning, intra-service orchestration, and application deployment.

Ansible Simple inventory management

KEY FEATURES

  • Efficient architecture: Ansible connects to your nodes and pushes out small programs (modules) to them, and these are the resource models of the desired state of the system. After these modules are executed, Ansible removes them when done. The modules can be in any machine, and there’s no need for servers, daemons, and databases.
  • Lots of options: The default way to use Ansible is with SSH keys with ssh-agent. But passwords are supported too, and you can also use Kerberos. With the Ansible “authorized_key” module, you can control which machines can control which hosts.
  • Simple inventory management: Ansible represents the machines it manages with a simple INI file. This puts all your managed machines in the grouping you prefer. If you want to add new machines, it doesn’t involve additional SSL signing server. So you won’t have trouble regarding a machine that didn’t get linked due to some DNS or NTP problem.
  • App deployment: This is ridiculously simple, and you can deploy multi-tier applications consistently and reliably.
  • Complex orchestration: You can organize and manage complex deployments with no trouble. You won’t have problems with multiple datacenters, clustered applications, applications with complex dependencies, or various types of clouds.
