Yes, that's very much true. Ansible is a new culture in any organisation. It encourage great communication and collaboration between team and their work. It helps in building better quality software quickly and can be reliable..
Ansible is simple yet powerful. It is a great automation tool and does have great future.This opens up a world of possibilities. There would be enterprises who require atleast one of the above services and watching the market trends, Ansible does look like the preferred choice. The agentless approach, easy to maintain YAML format code, etc have made it a no brainier when it comes to deciding between the multiple options for Infra provision and config management..
There are two available choices: check and run. The behavior of the template will change depending on which you select.
- Check performs a “dry run” of the playbook and reports changes that would be made without actually making them. Some tasks that have specific modules that do not support check will be skipped automatically in the process and will report nothing back.
- Run will execute the tasks in the playbook on the selected hosts. Depending on what the playbook does, this will determine the type of job that needs to be selected.
We are happy and proud to say that we have strong relationship with over 700+ small, mid-sized and MNCs. Many of these companies have openings for Ansible analyst. Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
Ansible can automate IT environments whether they are hosted on traditional bare metal servers, virtualization platforms, or in the cloud. It can also automate the configuration of a wide range of systems and devices such as databases, storage devices, networks, firewalls, and many others.The best part is that you don’t even need to know the commands used to accomplish a particular task. You just need to specify what state you want the system to be in and Ansible will take care of it..
Some prerequisites for learning automation tools like Puppet / Chef / Ansible are:
1*) Being good at UNIX is helpful, but not required.
2*) Yes, you should know programming/coding languages in order to write Puppet
Manifests or Chef Recipes - you need to have knowledge of Ruby on Rails.
When not feeling natural at scripting or programing, it may seem that configuration management tools would be something that you can’t become proficient with, but this is not true, it just takes a little more effort. Great thing about Ansible that it does not require any programming knowledge to use it. This is one of the reasons why the tool is so popular.
Our courseware is designed to give a hands-on approach to the students in Ansible. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
It is worth using for the similar reasons to other configuration management systems. It is much better to use templates, and version control and be able to rebuild things from scripts that you have confidence in.
Ansible has a pretty low learning curve, you can pick it up really quickly.It has a lot of features, so don’t expect to learn everything together, but from the point of view of getting comfortable with syntax and architecture, 1 week is more than enough. Everything after that is learning by implementation..

Popularity of Ansible
Ansible streamlines and simplifies cloud provisioning, configuration management, application deployment, intra-service orchestrations and similar emerging IT systems, processes and infrastructure, explains webopedia. In layman’s terms, it makes it easier to create computer software and processes.Although Ansible is a young product, it already has wide acceptance among IT experts because of its simplicity and flexibility.After switching to Ansible, he reports the team created full-blown automation infrastructure within a couple months.
Here are the top 5 reasons Ansible is becoming the go-to solution for a variety of IT operations.
Easy to begin
- Operating under the premise that automation shouldn’t be more complex than the tasks it’s replacing, Ansible is a simple automation language that is easy-to-learn, self-documenting and doesn’t require a grad-level computer science degree to read.
- Ansible can be used to update programs and configuration on hundreds of servers at once, but the process is the same whether you’re managing one computer or dozens.
Enterprise support from Red Hat
- Like many other Red Hat products, Ansible is open source. However, it is supported with a subscription from Red Hat.
- The beauty of allowing people free access to technology is that open source communities become the driving source of innovation, Adam Clater, chief architect at Red Hat, explains.
- It also allows for comprehensiveness of applicability that provides flexibility so users can find creative ways to adapt the product for their needs.
Accelerated automation
- Ansible is agentless, and that means it can be set up in minutes using OpenSSH without installing anything on the servers.
- In order to be effective automation must be simple.
- People embrace technologies that are easy to understand and to adopt.
Simplifying information technology
- As an organization grows, one common challenge is people of different skill sets and experience need to use the same technology.
- If the only people who know how to operate everything are a small group of IT specialists, there will be problems.
- “One of the reasons Ansible is winning the day against other automation mechanisms is that it is significantly easier for an untrained operations-type person that is not a coder to be able to automate using Ansible,” explains Steven Carter, chief cloud architect for Red Hat’s public sector.
Information power multiplied
- Ansible is one of the most popular open source automation projects on GitHub with an active and engaged community, reports Yahoo! Finance. New Ansible users can learn quickly and benefit from experienced Ansible users.
- That helps the automation process move even faster.
- There is also Ansible Galaxy, where Ansible users provide prepackaged units of work called roles.
- Thousands of members are sharing thousands of these roles, which simplify tasks like provisioning infrastructure or deploying applications.
- The primary benefit of Ansible is it allows IT administrators to automate away the drudgery from their daily tasks.
- That frees them to focus on efforts that help deliver more value to the business by spending time on more important tasks. Ultimately, Ansible gives teams time to allow smart people to focus on smart things.
Advantages of Ansible
- Free : Ansible is an open-source tool.
- Very simple to set up and use : No special coding skills are necessary to use Ansible’s playbooks (more on playbooks later).
- Powerful : Ansible lets you model even highly complex IT workflows.
- Flexible: You can orchestrate the entire application environment no matter where it’s deployed. You can also customize it based on your needs.
- Agentless : You don’t need to install any other software or firewall ports on the client systems you want to automate. You also don’t have to set up a separate management structure.
- Efficient : Because you don’t need to install any extra software, there’s more room for application resources on your server.
Next, in our path to understanding what ansible is, let us find out the features and capabilities of Ansible.
Uses of Ansible
Another important aspect under-emphasis before ansible advantages refers to the applications of ansible. The applications of Ansible can help in obtaining brief insights into their benefits for DevOps. The different applications of Ansible include provisioning, configuration management, deploying applications, security and compliance, and orchestration. The long list of applications clearly shows that Ansible is not just another configuration management tool. So, we can note that the advantages of Ansible come primarily from its applications.
Ansible in the DevOps Movement
The fit of Ansible in the DevOps lifecycle can also provide viable insight into the benefits of Ansible. Ansible provides support for integrating development and operations in contemporary test-driven application design. It provides a stable environment for the development and operations team, thereby leading to smooth orchestration. Ansible automation helps considerably with the representation of Infrastructure as Code (IAC).
IAC involves provisioning and management of computing infrastructure and related configuration through machine-processable definition files. Therefore, administrators could find opportunities to work in collaboration with developers that improves development speed. Also, the benefits of ansible help in focusing more on performance tuning and experimenting rather than fixing issues.
