Agile vs DevOps – Difference and Comparison

What is Agile?

The Agile technique focuses on the Agile manifesto, which was authored by a team of developers then released in 2001. It develops a more adaptable, code-centered, collaborative software development technique than Waterfall, with an emphasis on:

  1. Individuals and interactions above procedures and tools.
  2. Functional software trumps extensive documentation.
  3. Cooperation with clients instead of collective bargaining.
  4. Changes to the project plan.

Scrum, a team concept centered on iterative activities done in “sprints,” and Kanban, a lean technique for organizing work around human-based systems, are two common frameworks supported by this rather formal development process.

Unlike the Waterfall method, agile development and testing take place simultaneously rather than sequentially. Teams work directly with company owners and consumers, including them in every stage of the process. The documentation is minimal. After each sprint, feedback is asked often, and quality concerns are rectified.

What is DevOps?

Agile’s advanced branch is DevOps. Its plans plan is to bring up the bridge, inter groups in a cooperative atmosphere that combines development, testing, QA, management, privacy, and key stakeholders throughout the lifecycle of the project to enable IT more reactive to company requirements. As a result, continuous testing, integration, delivery, and deployment of reliable, high-quality software is made possible, led by constant feedback – and aided by automation.

“The Three Ways” of DevOps, according to Gene Kim, a prominent researcher, author, and CTO, are:

  1. The actual speed of technology to give value to the client from development through operations.
  2. Continuous improvement of feedback loops to improve corrections.
  3. A culture of trying and learning must be fostered to master continual improvement and innovation.

Before a business implements a DevOps environment, it must first integrate an agile development process into a collaborative people culture and support the project with the appropriate technology.

Difference Between Agile and DevOps

  1. Agile facilitates the management of complicated projects by emphasizing an iterative strategy that allows for customer input, collaboration, and short, frequent releases. DevOps is a philosophy that brings software development and operations teams closer together, bridging the gap.
  2. DevOps focuses on the communication gap between developers and IT operations teams, whereas Agile focuses on the communication gap between developers and customers.
  3. Agile emphasizes continual change and activities that allow for and accept it. DevOps emphasizes continuous software testing and delivery.
  4. Scrum, SAFe, and Kanban are some of the frameworks used to execute Agile. These are coalition-friendly tactical frameworks. DevOps is a philosophy that emphasizes teamwork. As a result, there is no widely acknowledged framework. Puppet, Chef, Ansible, Docker, Jenkins, Git, TeamCity, and other tools are used to implement DevOps.
  5. Agile emphasizes the significance of training all members of the development team in a number of related skills. Agile development teams are intended to have a T-shaped skill set, which consists of both generic domain abilities and in-depth expertise in a single specialty. DevOps guarantees that software development teams and operations teams share capabilities.

Comparison Between Agile and DevOps

Parameters of ComparisonAgileDevOps
Communication and Project GoalsAgile closes the gap between clients and developers in terms of communication. Consumer input is required and valued, and all feedback for the next product release is contingent on the customer. Agile has lengthier release cycles as a result of this reliability.Developers and IT operations can communicate more effectively using DevOps. Customers are valued in DevOps, although input is provided by the internal team, resulting in rapid release cycles and product scope.
ModelAgile has a specific methodology derived from tactical frameworks such as safe, scrum, and sprint. Safe focuses on the flexibility of the team, the program, and the portfolio. Scrum relies heavily on daily verbal discussions and minimal documentation. Sprint focuses on short-term monitoring (less than a month).DevOps lacks a formal structure and instead emphasizes a collaborative atmosphere. DevOps discusses and documents the hardware, network, and software capabilities so that everyone is on the same page throughout the deployment. DevOps is concerned with day-to-day reporting and code delivery to production. The time it takes to submit code might range from a few hours to a whole day. It provides a more exact estimate and approaches to the amount of code created in a day, allowing daily targets to be set.
Process Agile is an iterative approach that emphasizes cooperation and customer input to provide frequent, high-quality releases.DevOps, on the other hand, emphasizes regular continuous testing and delivery by bringing the development and operations teams together to have a better understanding of the situation. They may continue to improve without client feedback.
The TeamAgile employs smaller, more dependable teams, with each team member owning a wide range of talents and the ability to fill in for those who are unavailable. The faster the movement, the smaller the squad. Due to the limited size of their team, each person must be more productive and proactive.DevOps, on the other hand, brings together development and operations teams and assigns everyone particular roles. Because shareholders are included, it has a somewhat greater size. Because everyone is a master of their expertise, the team lacks the capacity to cross-function. Production, development, and implementation must all flow smoothly in DevOps.
Test Shifting There is a shift left in Agile development for testing the product.In DevOps, however, there is a spread shift that can go right or left depending on the situation. The benefit is that the product is tested after a certain procedure is done, which is not feasible in shift-left when some components of the project have not been completed.
