DevOps is a culture that promotes collaboration between software development and the operations team. This helps in communication, integrations, and collaboration among IT professionals to support the rapid deployment of software products into production in an automated way. DevOps culture enabled companies to increase the speed of delivering their applications and services.
Agile is a software development method that emphasizes an iterative and incremental approach to software development or project management. Agile enables continuous iterations of development and testing in the Software development life cycle. Agile essentially breaks down the software product into smaller pieces for the ease of development and integrates them for the final testing.
Differences between Agile and DevOps
1. The Main Purpose
Agile helps to manage complex projects with a strong focus on the iterative approach that enables customer feedback, collaboration, and small, rapid releases. While DevOps is a philosophy that brings software development teams and operations teams together reducing the gap between them.
2. Addressing Communication Gaps
Agile focuses on filling the communication gaps between the developer and customer, while DevOps focuses on the communication gap between developer and IT operation teams.
3. The Focus on Tasks
Agile focuses on constant changes and tasks that enable and embrace changes. DevOps focuses on constant software testing and continuous delivery.
4. Implementation Methods
Agile is implemented using different frameworks like Scrum, SAFe, and Kanban. These are tactical frameworks that can be used in a coalition. DevOps is a philosophy that focuses on collaboration. So there is no commonly accepted framework. DevOps is implemented using tools like Puppet, Chef, Ansible, Docker, Jenkins, Git, TeamCity, etc.
5. Team Skillset and Focus Areas
Agile prophesies the importance of training all the development team members to have a variety of similar skills. Agile development teams are expected to have a T-shaped skill set, which is more of having generalized skills across the domain and in-depth knowledge in one skill. DevOps ensures the spread of skills between the software development teams and operation teams.
6. Team Size
Agile needs relatively small teams to execute the quick bunch of tasks. The idea is that smaller teams with fewer people on it can deliver work faster. DevOps can have large teams as it involves different working pieces.
Agile is usually managed in units of sprints. Sprints usually run for a period of two weeks or a maximum of a month. DevOps concept deals with major and minor releases. Minor releases can happen very frequently, and the goal may be to deploy the code on production daily.
For Agile feedback is given by the customer. In DevOps feedback, is given by the internal customers. For example, the continuous testing team will test the code and provide feedback to the developers in case of bud or issues.
9. Target Areas
The main target of Agile is the software development itself. DevOps, on the other hand, focuses on an end-to-end business solution that can be delivered faster. For example, DevOps can also be used for Infrastructure services, which is far different from software development.
Agile emphasizes on development alone. Agile takes care of the pathway through development and release but does not take care of what happens after its release to production. DevOps, on the other hand, takes the software which is tested and ready for release and deploys it in a secure and reliable production environment.
Agile focuses on cross-functional teams. Any team member must have the capability to do anything that is for the progress of the project. When each team member can do any piece of work on the project, it increases the bonding between team members. in the DevOps model, the development team and operational teams are separate, which makes the communication between them is very important.
Agile focuses on producing completed work as soon as possible. Agile’s goal is to build a working system or application and not any documentation for it. This school of thought works well when the teams are flexible and responsive. But in the modern world, in many scenarios, team members move in and out, teams are dismantled, and the application is handed over to another team.
In such cases, this approach of Agile has not proved worthy. In the DevOps model, documentation has it’s due importance because the software is sent to the operational team for deployment. DevOps creates a lot of automation, minimizing the requirement of documentation, but as today’s software is a highly complex and good degree of documentation is required.
In the Agile methodology, there is no emphasis on automation. Agile is all about manual labor but done in quick bursts of energy. DevOps is all about automation and keeps minimizing manual effort as the primary goal. DevOps works on the principle of maximizing efficiency when deploying code.
14. Speed and Risk
Agile teams must be able to handle rapid changes but keeping the risks minimal and building a robust application. In DevOps, there is not much emphasis on speed. More focus is given to reducing risks on the software and deploying the software in a reliable environment.
Agile focuses on quality while embracing changes from customers. The deliverable produced during each sprint is to be compared against the acceptance criteria for quality checks. DevOps, too, give proper emphasis on quality. The automation, early bug removal, and reliable deployment environment ensure the quality of the software.
Agile provides short development cycles with improved defect detection ensuring faster software delivery. DevOps with the build-to-deployment automation can support Agile’s release cycle. So, most companies have started using an Agile DevOps combo.
Let’s conclude on Agile vs DevOps
Agile and DevOps are entirely different schools of thought. When Agile refers to the approach in which software is built, DevOps considers bringing development teams and operations teams together to deploy solutions to production faster. Though this difference is prominent, DevOps is used to support the rapid release cycle of Agile methodology.
So these are the significant differences between Agile and DevOps. We hope this article has made things clear about Agile and DevOps and their differences.
