DevOps Vs Agile Methodology- A Comparison

DevOps vs Agile

Evolution of software development has three important milestones. Waterfall method focused on the time required to release a product, then agile methodology which optimized the development life-cycle. Now, DevOps seeks to unite development and operations to work together as a single team. It expands efficiency, improves coordinated effort, and conveys predominant items. It improves productivity, collaboration and delivers superior products. Embracing agile and DevOps practices in software development presents a challenge to many. First step to overcome this issue is understanding the difference between agile and devops. Here we’ll see the difference between DevOps vs Agile. Before digging to the comparison, let us see overview of Devops and agile.

What Is DevOps?

DevOps is a software development method that focuses on communication, integration and collaboration among IT professionals for rapid deployment of products. Also, it is a culture that promote collaboration between development and operation team. DevOps allows to deploy code to production rapidly and in an automated way. It also helps to increase an organization’s speed to deliver app and services. It can be defined as an alignment of development and IT operation.

Goal Of DevOps-

  • It focuses on creation of a culture for continuous improvement and innovation using experimentation and learning.
  • DevOps works on CALMS- culture, automation, lean, measurement, and sharing.
  • One can employ automation to attain better software delivery performance, that has a positive impact on organization in terms of revenue, net worth and customer satisfaction. 
  • With an inclusive team, you can easily prepare, deploy and deliver software after testing without sacrificing quality if you have proper documentation.

What Is Agile?

Agile Development

Agile methodology includes continuous iteration of development and testing in the SDLC process. It also focuses on iterative, incremental and evolutionary development. The Agile development process divides product into small parts and integrates them for final testing. It can be implemented in lots of ways, including scrum, kanban, scrum, XP etc. 

Goal Of Agile –

  • Agile methodology focuses on a specific project and they cycle stops after completion of the project.
  • It uses smaller manageable teams who can work with changes based on immediate customer feedback.
  • It ensures rapid implementation and task execution within a time frame without compromising quality with its sprints. 
  • Face to face communication is best way to convey information and  necessary
  • Skilled and motivated people working in a team will give best results
  • Success measure comes from working software
  • Sustainable companies focus on customer needs instead of contract negotiation 

DevOps Vs Agile : Differences Between DevOps And Agile

1. Communication And Project Goals –

First point of comparison of DevOps Vs Agile is Communication and project goals. DevOps fortifies communication among developers and IT operations. In DevOps, they value the customer, but feedback comes from the internal team, that causes immediate release cycles and product scope.

Agile addresses communication gaps between developers and customers. They require and value the opinions of the customer, and all feedback for the next product release is reliant on the customer. Because of this dependability, Agile has long release cycles.

2. The Team- 

DevOps incorporates development and operations teams together with particular tasks for everyone. It has larger size as it includes stockholders also. The team doesn’t have the ability to cross-function since everyone is an expert of their respective skill. Devops requires a streamlined flow of production, development and implementation.

Agile methodology uses small and reliable teams with each team member having many skills, who can fill in positions of absent people. If the team is small, the movement will be faster. Also, because of a smaller team, each member should be more productive and proactive. 

3. Development Process-

DevOps process, focuses on frequent testing and delivery, with the help of development and operation team together for a clear picture. They can improve without feedback from customers.

Agile is an iterative process which focuses on collaboration and customer feedback to provide frequent releases which focus on quality improvement.

4. Focus-

DevOps focuses equally on development, testing and implementation by involving operations team, developers and testers. It encourages business and operational readiness in the organization. However, DevOps needs to factor consistently in detail, and any small change can cause deployment issues later. 

Agile methodology focuses on software development by involving developers and testers to go through developmental readiness. Because of the development team, they can do last-minute changes when required according to customer specifications.

5. Targeting –    

DevOps team ensures the security of software deployment and reliably after the software is ready for release and provides complete business solutions and quick delivery. Devops eases the end-to-end process.

Agile team continues software development, when the software is ready for release and it won’t fret over the product post-release. Agile is best suited for complex, high-quality projects.

6. Automation-

DevOps need to follow coding and architecture of application. Automation helps to detect and remove bugs in app, from early stages making it simpler and faster. 

Agile doesn’t need automation as the processes are restricted, you can still use it to improve productivity.

7. Responsibility-

In the DevOps system, developers, testers and operations departments are a single unit and the DevOps engineers are altogether responsible for the project.

In organization with Agile, people can refuse to accept responsibility for the issues, since individuals are responsible for various tasks, and no can be considered responsible for the issue.

8. Tools –

DevOps and Agile both uses different tools as per the project requirement. Agile uses popular project-management tools like Kanboard and Jira project management software and Bugzilla server software. DevOps uses tools such as AWS cloud computing services, Puppet automation software, teamCity servers, OpenStack software and Chief infrastructure.

9. Documentation – 

DevOps documentation is required to transfer all the necessary knowledge to automate software deployment.

Basic idea of agile is cooperation with customer is more important than contractual obligations. That is the reason Agile methods strive to lessen the amount of documentation. This allows the customer to pay just for the result that has value for the business.

DevOps And Agile – Can They Be Used Together?

A mix of both methodologies can be used to improve efficiency.  Both plays major roles to play when it comes to software development and deployment, and one can be used to enable the other. 

Final Words-

DevOps is a practice of bringing development and operations teams together whereas Agile is iterative approach that focuses on collaboration, customer feedback and small rapid releases.
