Ansible is an open-source IT configuration management and automation platform. It practices human-readable YAML templates so users can program repetitive tasks to proceed automatically without having to learn an advanced programming language.
Ansible is agentless that indicates the nodes it controls do not need any software to be installed on them. This excludes possible security vulnerabilities and advances overall management smoother.
Earlier, maintaining IT infrastructure was a hard job. System administrators had to manually operate and configure all of the hardware and software that was demanded by the applications to run.
Nevertheless, in recent years, things have improved dramatically. Trends like cloud computing revolutionize and improve the way organizations design, develop, and maintain their IT infrastructure.
Advantages Of Using Ansible
- Simple: Ansible uses a simple syntax written in YAML called playbooks. YAML is a human-readable data serialization language. It is extraordinarily simple. So, no special coding skills are required and even people in the IT organization, who do not know what is Ansible can likely read a playbook and understand what is happening. Ansible always executes tasks in order. It is simple to install too. Altogether the simplicity ensures that you can get started quickly.
- Agentless: Finally, Ansible is completely agentless. There are no agents/software or additional firewall ports that you need to install on the client systems or hosts which you want to automate. You do not have to separately set up a management infrastructure which includes managing your entire systems, network and storage. Ansible further reduces the effort required for your team to start automating right away.
- Powerful & Flexible: Ansible has powerful features that can enable you to model even the most complex IT workflows. In this aspect, Ansible’s batteries included approach can manage the infrastructure, networks, operating systems and services that you are already using, as Ansible provides you with hundreds of modules to manage them. Together Ansible’s capabilities allow you to orchestrate the entire application environment regardless of where it is deployed.
- Efficient: No extra software on your servers means more resources for your applications. Also, since Ansible modules work via JSON, Ansible is extensible with modules written in a programming language you already know. Ansible introduces modules as basic building blocks for your software. So, you can even customize it as per your needs.
One of the crucial ingredients of this trend is called “infrastructure as code”. Infrastructure as Code (IaC) is the management of infrastructure in a descriptive model, using the same versioning as the DevOps team uses for source code. Like the principle that the same source code generates the same binary, and the IaC model generates the same environment every time it is applied. IaC is a key DevOps practice and is used in conjunction with continuous delivery.
Most Noteworthy, Ansible Tower helps you manage your entire infrastructure. Easily pull your inventory from public cloud providers such as Amazon Web Services, Microsoft Azure, and more, or synchronize from your local OpenStack cloud or VMware environment.
Ansible modules are standalone scripts that can be used inside an Ansible playbook. A playbook consists of a play, and a play consists of tasks. These concepts may seem confusing if you’re new to Ansible, but as you begin writing and working more with playbooks, they will become familiar.
Ansible works by connecting to your nodes and pushing out small programs, called “Ansible Modules” to them. These programs are written to be resource models of the desired state of the system. Ansible then executes these modules and removes them when finished.
Ansible architecture is fairly straightforward. Ansible makes IT automation accessible. Ansible is the simplest solution for configuration management available. It’s designed to be minimal, consistent, secure and highly reliable, with an extremely low learning curve for administrators, developers and IT managers.
Ansible configurations are simple data descriptions of your infrastructure ensuring everyone on your team will be able to understand the meaning of each configuration task. New team members will be able to quickly dive in and make an impact. Existing team members can get work done faster – freeing up cycles to attend to more critical and strategic work instead of configuration management.
In DevOps, as we know development and operations work is integrated. This integration is very important for modern test-driven application design. Hence, Ansible integrates this by providing a stable environment for both development and operations resulting in smooth orchestration
