Ansible: An Effective IT Automation Tool

Ansible is an effective IT computerization tool that is used to program application deployment, cloud provisioning, configuration management, etc. It is specifically designed for multi-tier deployments and models IT infrastructure by defining how system management can be interrelated instead of managing each of them individually. One of the best aspects of this engine is that it doesn’t employ any agents or additional custom security infrastructure making it effortless to deploy. It further uses a simple language that allows the system admin to describe automation tasks in simple English. Ansible, by default, represents the nodes it manages using simple files that categorize the managed documents and files in custom groups. Instead of managing individual node or system one at a time, the tool configures every node to the labeled format.

How Does Ansible Work?

Now that we know what Ansible is, let’s delve into how it works to provide utmost system efficiency in a server. Ansible hosts are well-structured and described in a file

which is organized in Playbooks and groups that can be applied to distinct sets accordingly. These hosts are addressed by the usage, as well as other, operational aspects. Additionally, each of these hosts can have custom variables like sudo passwords, SSH, etc. In Ansible, Playbooks are considered the key basis of multi-machine deployment system and configuration management. Playbooks don’t merely state the configurations; it can also direct the entire procedure of even manually directed process. They are defined in YAML format, which makes them pretty straightforward to read and comprehend. Each of the playbooks is composed of multiple plays in a list. The play focuses on organizing a group of hosts into a set of well-defined roles, which are represented by tasks in Ansible. On a basic level, a task is a normal request to an Ansible module to automate various configurations.

Thus, on creating a Playbook by encompassing different plays, one can coordinate and organize multi-machine deployments that run a set of specific actions on all machines in the web and database server, and then send commands back to the database server. By being idempotent in characteristic, Playbooks ensure the system remains in an adequate state and automate tasks only when required.

Why Should IT Firms Opt for Ansible?

With an array of similar IT solutions like Salt, Chef, etc., what makes Ansible the most popular choice?

One of the main reasons that IT companies opt for Ansible is because of the absolute simplicity of the tool. Additionally, the server systems are the foundation of the application, therefore it is imperative that they should be effectively tested, controlled, and automated. Subsequently, different configuration management tools are used to accomplish the stated tasks. And configuration management tools are not a new phenomenon in the IT world; however, complexities associated with them always created stumble blocks in their adoption. With Ansible, however, this difficulty in integration has been significantly lowered, which makes the usage of the configuration tool easier than performing shell scripting and other manual tasks. It has turned out to be a reliable option for projects and tasks that require a repeated process in a consistent environment like server infrastructure, provisioning IoT devices, application installation, and configuration, etc. The maker of Ansible, Michael DeeHaan, further simplified the tool by eliminating the need for any agents. Therefore, rather than having the need to place an agent on every system, the tool only requires that the system incorporate PowerShell (Window server), SSH, and Python (Linux server).

How Does Ansible Enhance DevOps?

DevOps is a simple term for a group of concepts that are significantly emerging in the technical realm. Basically, it is a software engineering community and practice that focuses on uniting the software development and software operations. The key functioning area of this practice is to promote, monitor, and automate every software construction process like testing, integration, infrastructure management, etc. An effective approach towards automation can change the current DevOps, helping in modernization and faster application deployment.

With a simple to use and adopt work frame, Ansible is an IT tool that is designed to integrate systems and allow collective management of tasks. This makes it an ideal solution to modernize and increase the deployment process of DevOps

As for the augmentation of Dev, it requires spending time determining the tool required for the task to deliver capabilities, however, unfortunately, not enough time is spent focusing on the results. This is where Ansible emerges as a tool that responds and scales the requirement with respect to the demand. This allows accelerated feedback loop, increases the coordination, avails more reliable deployments, identify bugs faster, etc.

Coming to the streamlining of Ops, the primary challenge is the need of technology which can be utilized for various groups accompanied with distinct skills. And here, Ansible offers a centrally monitored and controlled disparate system that reduces shadow IT, deployment time, accelerates the provisioning system, reduces the tribal knowledge risk, etc.
