More and more organizations have started adopting DevOps to improve their performance in recent times. As DevOps has gained popularity among businesses, it has also become a widely adopted career path for many IT professionals.

People take up DevOps course and certification programs to learn in detail about this area of study and become refined DevOps professionals. This allows them to secure better jobs in this fast-growing field.

Let’s get a better understanding of DevOps and its lifecycle.

What is DevOps?

If you think DevOps is a technology or platform, you are completely wrong! It is actually a method of software development that combines the functions of software development and IT operations. In DevOps, Dev refers to development and Ops refer to IT operations.

DevOps approach promotes collaboration between developers and operation engineers throughout the entire lifecycle. The idea behind this approach of development is to speed up the software development lifecycle and deliver applications and services faster and more efficiently.

Developers can upgrade the features of the software, fix any bugs and enhance the performance of the software without rolling back the software, using this approach. This allows organizations to provide better services to customers.

What is the Need for DevOps?

DevOps development is a constant loop of feedback and learning. Error handling is done through iterations which allows efficient business operations and ensures maximum productivity.

Here is how DevOps allows efficient software development:

  1. It improves development frequency. That is, the time required for software development is shortened and developers are able to release products faster.

  2. DevOps significantly reduces the time to market. It allows streamlined software delivery which reduces up to 50% of the time to market.

  3. It also reduces the failure rate of new releases

  4. It allows developers to version all applications so that previous versions can be restored in the future if required.

  5. As the older versions are stored, it makes the software more maintainable. In case the new version crashes due to unexpected errors, the older version can be recovered.

  6. DevOps integrates infrastructure issues which help developers in building more reliable and better quality software.

  7. DevOps development also reduces risks in the software as security aspects are included in the software development lifecycle.

  8. DevOps is a cost-efficient form of software development.

  9. As DevOps is based on agile development, it allows developers to break down large and complex code into smaller and manageable parts.

  10. DevOps is an iterative development method. Therefore changes can be easily incorporated in the software at a later stage.

DevOps Lifecycle

To get a better understanding of DevOps, it is important to first understand the DevOps lifecycle in detail.

The DevOps lifecycle consist of 5 main phases:

  1. Continuous Development

  2. Continuous Testing

  3. Continuous Integration

  4. Continuous Development

  5. Continuous Monitoring

Continuous Development

Development is the first and the most important part of the DevOps lifecycle. This phase is divided into small and separate development cycles. It takes place continuously and the smaller cycles take lesser time to develop. This speeds up the development and delivery process.

The different cycles involved in software development are:

  • Requirement gathering

  • System design

  • Software Development

First, all the software requirements are gathered from the customers. Then a system design is created in order to give the developers and customers a clear knowledge of what to expect from the end product. Lastly, the system is developed according to system design.

Continuous Testing

Testing is again a continuous activity in the DevOps approach. Small sections of the code are tested continuously at every stage of the development process. The tested code is then integrated into the main code.

QA teams use testing tools like Selenium, JUnit and more to fix bugs in the system and to ensure that the code works efficiently.

Continuous Integration

As small sections of code are tested they are continuously integrated with the prevailing code. This ensures that the prevailing code is ready to be integrated with the new code. Thus, the testing and integration phases take place simultaneously so that the code is free of errors after integration.

Continuous Deployment

In the DevOps approach, the code deployment takes place continuously. Deployment is performed in such manner that any changes made to the code do not affect the runtime or functioning of even high traffic websites.

For continuous deployment automation tools like Puppet, Chef, SaltStack and more are used.

Continuous Monitoring

Continuous monitoring is also an important phase of the DevOps approach. Any changes to the code are monitored to check if the system works properly.

What is the Future of DevOps?

As more and more organizations are adopting a DevOps approach, the future of DevOps looks quite promising. Here is what the future of DevOps will look like:

  • DevOps will become the new ALM methodology

  • DevOps engineers will have more control of the end user as compared to anyone in the organization

  • DevOps automation tools are bound to increase in number with the popularity of this approach

  • Security will become the primary focus of software with DevOps continuous development and integration approach.

  • DevOps engineers are becoming the highest paid IT professionals.

  • DevOps skilled professionals will be valued and preferred over people with no DevOps skills. This is because a DevOps professional is skilled not only in development and coding but also has knowledge of infrastructure, testing, building and more.

Conclusion

DevOps is undoubtedly changing the dynamics of the IT industry by combining the development and operations processes and helping organizations deliver quality products and services. As DevOps has is gaining popularity, the need for DevOps professionals has also increased.

For this reason, DevOps courses and certifications are valued by recruiters all around the world. A DevOps certification is proof that you are skilled in all aspects of DevOps, that is, development as well as operations.

If you want to build a successful career path in DevOps you should take the online DevOps certification which will help you become a refined and skilled professional.
