The Era of Cloud is here, where you can dynamically create IT infrastructure faster than ever before. This has been made possible by many cloud providers, including Amazon Web Services, Azure and Google Compute Engine. This has changed our perception of IT infrastructure, but it has also increased complexity. You now have to ask yourself “How are you going manage these servers?” How will you automate deployments? DevOps professionals and system administrators have made it simple to use configuration management tools to automate tasks related to managing large numbers of servers. Ansible, a Python-based configuration management tool, is becoming increasingly popular in the configuration management field. Ansible automates complex tasks such as provisioning cloud instances, configuring packages, patching them, and deploying apps.
What makes Ansible so great for Devops?
We are often asked these questions:
We already use a configuration tool. What difference will Ansible make?
How do we configure agents on our fleet servers?
How is this tool going do its job in configuring our large fleet of vehicles?
Do we need to learn a new programming language to use this tool?
Is it worth it to have Ansible manage one more node?
Here are the answers to all your questions:
Agent less:
Ansible is not agentless, which means you don’t have to install agents on servers or manage them like other configuration management tools like Puppet and Chef. Ansible’s agentless architecture has many advantages. It communicates through SSH, zero bootstrapping, and resource utilization. Ansible is a network security tool that uses key pairs and SSH.
Ansible uses “playbooks”, which are used to define the actions that must be taken on each instance. Ansible playbooks can be run as many times as you like, and the state will not be affected unless a change is made. Your system will not be broken by playing with your playbooks.
Push-Based Model:
Ansible is a tool that allows you to push commands and make changes directly on our servers. You can also push commands to specific groups within our vast fleet of servers. You can test a software application on a small group of servers before you apply it to the entire fleet.
It’s easy to use
Ansible is well-known for its simplicity. Although it is based in Python, the playbooks that do the job are based upon YAML. This makes them easy to comprehend. This tool is easy to use and requires no additional programming language. This means that there is less overhead for devops professionals and sysadmins to use it.
Master less:
Ansible is Masterless, which means that we can pull out our playbooks and get started with them. They can be used wherever we want, provided they are properly configured. There is no need to manage Master or scale it. Go master free!! !
Ansible playbooks can have roles that make it even more powerful. You can create a role in the database to configure it. You can add more roles to suit your fleet’s needs and Ansible will send you orders !!!! against your fleet. !
You can create your own modules with Ansible. You can create your modules in any language you like, and all you need is JSON output.
Cloud support:
Ansible offers a variety of plugins that can be integrated with different cloud providers’ APIs like AWS, Azure and Rackspace. You can automate tasks such as provisioning the insta
