Automation with Ansible

New Level of Automation with Ansible

Already heard about Ansible and what’s it capable of? No! Well then know that it’s a simple yet super-effective automation tool that needs no agent and used widely for a number of projects till date, taking the world of automation to a whole new level. Yes, it is still BASH that will be the very basic requirement for shell scripting for any sysadmin; but still, there’s no denying that Ansible has become a smooth yet crucial part of becoming successful in both as a developer and as a sysadmin. Keep on reading to know what Ansible offers in store for the industry of automation.

Easy Reaching the Desired State

Suppose, a server is in a state named as ‘X’, and a script is written for changing its position to another state, named as ‘Y’. But when you’ll run the script twice, it will fail to work as it will automatically start from the state Y, failing the very purpose of the script for which it is written. However, with Ansible, a declarative, easy to point and simple coding structure, getting to the desired state won’t be a problem at all. After all, Ansible is all about reaching the desired state fast, where every task is defined in ways, irrespective of the context of the initial state.

Simultaneous Working On Multiple Servers

When it comes to working on multiple servers at the same time, who can be better than Ansible again! Yes, leaving even the efficiency of the Python code behind, Ansible offers simple commands, using shell modules, for reporting git branch, upon which all the servers stand. While for day-to-day tasks, python codes can be not-so-productive, with Ansible, even working with hundreds or thousands of servers simultaneously become easier.

Report Changes and Dry Run

Though going from the very desired state of itself may sound not so important or trivial, but this particular task is used as ‘dry run’ for reporting deviations or any change from the desired state. Periodically used also for enforcing some policies, the Ad-Hoc commands offered by Ansible can be run easily for creating a directory. Not only for creating a directory, reporting the necessary changes in the commands if the command fails to run can also be done quickly in Ansible.

Creating Readable Playbooks

Thinking about creating readable playbooks? Why wait then when you have Ansible by your side! If BASH scripts, written by others, gives you a hard time in recovering your readability power, then why not try the Ansible playbooks as deploying a highly available complex cluster, they see to the matter that the playbooks remain both readable and simple.

Easy Orchestration

With Ansible doing serial execution to parallel and delegated execution and others are very much possible. Be it going to the load balancer and removing a server from it or doing some changes to the server, and then again placing it back in the load-balancer, you can do anything with Ansible at your service.

Though as simple as BASH, Ansible is a lot more than BASH. Anyone becoming proficient in Ansible, cannot only write super easy-to-read Ansible playbooks instead of the complex shell scripts but can also use the Ad-Hoc commands just as they use an interactive bash shell for creating a whole new smoother and better automation.
