What is Ansible? 

Ansible is a free and open-source solution for software provisioning, configuration management, and application deployment that enables infrastructure as code. It operates on various Unix-like platforms and can set up both Unix-like and Microsoft Windows systems. It comes with a declarative language for describing the system setup. Michael DeHaan created Ansible, which Red Hat acquired in 2015. Ansible works without an agent, connecting remotely through SSH or Windows Remote Management (enabling remote PowerShell execution) to complete its responsibilities.

Ansible is a software program that provides cross-platform computer assistance through simple yet effective automation. It is primarily aimed at IT professionals, who use it for application deployment, workstation and server upgrades, cloud provisioning, configuration management, intra-service orchestration, and practically anything else that a systems administrator performs on a weekly or daily basis. Ansible does not rely on agent software and does not require any additional security infrastructure, making it simple to set up.

Because Ansible is all about automation, each task requires instructions to complete. Version control is straightforward when everything is written down in a basic script style. The practical result is a significant contribution to the IT industry's "infrastructure as code" movement: the idea that server and client infrastructure maintenance can and should be treated similarly to software development, with repositories of self-documenting, proven, and executable solutions able to run an organization regardless of staff changes.

While Ansible is at the vanguard of automation, systems management, and DevOps, it is also valuable to non-technologists. Ansible allows you to configure not just one computer, but possibly a whole network of machines at the same time, yet it requires no programming knowledge to use. Ansible instructions are comprehensible by humans. Ansible files are simple to comprehend whether you're a computer novice or a seasoned pro.

What are the goals of Ansible? 

Ansible's design goals include the following:

Minimal in nature-Management systems should not impose additional environmental dependencies.

Consistent-Using Ansible, it should be possible to construct consistent environments.

Agents are not deployed to nodes by Secure-Ansible. On controlled nodes, only OpenSSH and Python are required.

Reliable-When designed correctly, an Ansible playbook can be idempotent, preventing unforeseen side effects on managed systems. It is feasible to write non-idempotent playbooks.

Playbooks employ a simple and descriptive language based on YAML and Jinja templates, requiring little to no experience.

How does Ansible work? 

There are two types of computers in Ansible: control nodes and managed nodes. The control node is a computer that is configured to execute Ansible. There must be at least one control node, with a backup control node optional. Any device that is handled by the control node is referred to as a managed node.

Ansible operates by connecting to network nodes (clients, servers, or whatever you're setting) and then sending a little program known as an Ansible module to that node. Ansible runs these modules through SSH and then removes them. The sole need for this interaction is that your Ansible control node has access to the managed nodes. SSH keys are the most often used method of providing access, however other kinds of authentication are available.

Automation administrators and operations teams make sure the automated platform and infrastructure are up and running. Administrators and operators have powerful tools in the automation controller and automation hub to more efficiently manage and share automation projects, with a common tongue and broadly available mix of command-line interfaces (CLIs), graphical user interfaces (GUIs), and word-based user interfaces (TUIs) across endpoints.

What are the benefits of using Ansible? 

Free-Ansible is a free open-source tool.

Simple-To utilizes Ansible's playbooks, no particular coding skills are required (more on playbooks later).

Power-Ansible is a powerful tool that allows you to model even the most complicated IT procedures.

Flexible-You can orchestrate the complete application environment regardless of where it is installed. You may also tailor it to your own requirements.

Agentless-You, do not need to install any additional software or open any firewall ports on the client computers that you wish to automate. You also do not need to establish a distinct management structure.

Efficient-Because no additional software is required, there is more space on your server for application resources.

What is the salary of an Ansible developer? 

The average compensation for an Ansible Developer is $77,016. Salary ranges from $27,872 to $330,340. When extra compensation and perks are taken into account, Ansible Developers in the United States can anticipate their overall pay value to be $93,003.
