How Ansible is solving Industries challenges?



Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Designed for multi-tier deployments since day one, Ansible models your IT infrastructure by describing how all of your systems inter-relate, rather than just managing one system at a time. It uses no agents and no additional custom security infrastructure, so it’s easy to deploy — and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English.

Advantages of Ansible

  • Free: Ansible is an open-source tool.
  • Very simple to set up and use: No special coding skills are necessary to use Ansible’s playbooks (more on playbooks later).
  • Powerful: Ansible lets you model even highly complex IT workflows.
  • Flexible: You can orchestrate the entire application environment no matter where it’s deployed. You can also customize it based on your needs.
  • Agentless: You don’t need to install any other software or firewall ports on the client systems you want to automate. You also don’t have to set up a separate management structure.
  • Efficient: Because you don’t need to install any extra software, there’s more room for application resources on your server.

Features and Capabilities of Ansible

  1. Configuration Management
  2. Application Deployment
  3. Orchestration
  4. Security and Compliance
  5. Cloud Provisioning


Ansible Architecture

1. Modules:

Modules are like small programs that Ansible pushes out from a control machine to all the nodes or remote hosts. The modules are executed using playbooks (see below), and they control things such as services, packages, and files. Ansible executes all the modules for installing updates or whatever the required task is, and then removes them when finished. Ansible provides more than 450 modules for everyday tasks.

2. Plugins:

As you probably already know from many other tools and platforms, plugins are extra pieces of code that augment functionality. Ansible comes with a number of its plugins, but you can write your own as well. Action, cache, and callback plugins are three examples.

3. Inventories:

All the machines you’re using with Ansible (the control machine plus nodes) are listed in a single simple file, along with their IP addresses, databases, servers, and so on. Once you register the inventory, you can assign variables to any of the hosts using a simple text file. You can also pull inventory from sources like EC2 (Amazon Elastic Compute Cloud).

4. Playbooks:

Ansible playbooks are like instruction manuals for tasks. They are simple files written in YAML, which stands for YAML Ain’t Markup Language, a human-readable data serialization language. Playbooks are really at the heart of what makes Ansible so popular is because they describe the tasks to be done quickly and without the need for the user to know or remember any particular syntax. Not only can they declare configurations, but they can orchestrate the steps of any manually ordered task, and can execute tasks at the same time or at different times.

Each playbook is composed of one or multiple plays, and the goal of a play is to map a group of hosts to well-defined roles, represented by tasks.

5. APIs:

Various APIs (application programming interfaces) are available so you can extend Ansible’s connection types (meaning more than just SSH for transport), callbacks, and more.

Advantages of Ansible

1. Simple:

→ Human readable automation

→No special coding skills needed

→Tasks executed in order

→Get productive quickly

2. Powerful:

→App deployment

→Configuration management

→Workflow orchestration

→Orchestrate the app lifecycle

3. Agentless:

→Agentless architecture

→Uses OpenSSH and WinRM

→No agents to exploit or update

→Predictable, reliable and secure

Challenges faced by industries Solved Using Ansible

Nasa challenges Solved by Ansible:

Nasa using Ansible


NASA needed to move roughly 65 applications from a traditional hardware based data center to a cloud-based environment for better agility and cost savings. The rapid timeline resulted in many applications being migrated ‘as-is’ to a cloud environment. This created an environment spanning multiple virtual private clouds (VPCs) and AWS accounts that could not be easily managed. Even simple things, like ensuring every system administrator had access to every server, or simple patching, were extremely burdensome.


Leverage Ansible Tower to manage and schedule the cloud environment.


As a result of implementing Ansible Tower, NASA is better equipped to manage its AWS environment. Tower allowed NASA to provide better operations and security to its clients. It has also increased efficiency as a team. By the numbers:

  • Updating went from over 1 hour to under 5 minutes.
  • Patching updates went from a multi-day process to 45 minutes.
  • Achieving near real-time RAM and disk monitoring (accomplished without agents).
  • Provisioning OS Accounts across entire environment in under 10 minutes.
  • Baselining standard AMIs went from 1 hour of manual configuration to becoming an invisible and seamless background process.
  • Application stack set up from 1–2 hours to under 10 minutes per stack.

“Ansible Tower has allowed us to provide better operations and security to our clients. It has also increased our efficiency as a team.”
