Agile

The Agile movement proposes alternatives to traditional project management. Agile approaches are typically used in software development to help businesses respond to unpredictability which refer to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. The primary goal of being Agile is to empower the development team the ability to create and respond to change in order to succeed in an uncertain and turbulent environment.

DevOps

DevOps word in itself is a combination of two words one is Development and other is Operations. It is neither an application nor a tool; instead, it is just a culture to promote development and Operation process collaboratively. As a result of DevOps implementation, the speed to deliver applications and services has increased.

DevOps enables organizations to serve their customers strongly and better in the market. In other words, we can say that DevOps is the process of alignment of IT and development operations with better and improved communication.

DevOps Vs. Agile

Despite their similarities, DevOps and agile are not the same, and some argue that DevOps is better than agile. To eliminate the confusion, it’s important to get down to the nuts and bolts.

Similarities

  • Both are software development methodologies; there is no disputing this.
  • Agile has been around for 20 years, and DevOps came into the picture fairly recently.
  • Bothe believe in fast software development, and their principles are based on how fast software can be developed without causing harm to the customer or operations.

Differences

  • The difference between the two is what happens after development.
  • Software development, testing, and deployment happen in both DevOps and agile. However, pure agile tends to stop after these three stages. In contrast, DevOps includes operations, which happen continually. Therefore, monitoring and software development are also continuous.
  • In agile, separate people are responsible for developing, testing, and deploying the software. In DevOps, the DevOps engineering role is responsible for everything; development is operations, and operations is development.
  • DevOps is more associated with cost-cutting, and agile is more synonymous with lean and reducing waste, and concepts like agile project accounting and minimum viable product (MVP) are relevant.
  • Agile focuses on and embodies empiricism (adaptation, transparency, and inspection) instead of predictive measures.

Key Differences Between Agile and DevOps

Both are recommended options in the business. Let us examine some of the key difference:

  • Agile is about software development and DevOps is about Software Development and Management.
  • Agile operates in sprints whereas DevOps stresses more on deadlines and benchmarks.
  • Agile does not believe in automation whereas in DevOps automation is at its core.
  • DevOps needs to be Agile for faster and better efficiency of the desired results, but the reverse does not hold any value.
  • Agile is in the mid of LEAN DEVELOPMENT and DevOps.

Agile vs DevOps Comparison Table

Let’s look at the top Comparison between Agile vs DevOps –

The Basis Of Comparison AgileDevOps
IntentionA development and management approach for managing complex projects.This is an end to end management process related to engineering.
TaskThe agile process focuses on constant changes.DevOps focuses on constant testing and delivery.
PracticesSome of the best practices adopted in Agile are listed below –Building a backlogSprint developmentDaily ScrumsDevOps also have some best practices that ease the process –Respond to changes quicklyCollaborate directly with users and incorporate their feedbackFocus on technical excellence.
Speed of ProductionAgile pertains largely to the way development is carried of, any department of the company can be agile in its practices. This can be achieved through training.DevOps focuses more on software deployment choosing the most reliable and safest route.
Team SkillsetAll the team members working in an agile practice have a wide variety of similar skill sets. This is one of the advantages of having such a team as because in the time of need any of the team members can lend assistance rather than waiting for the team leads or any specialist interference.DevOps has a different approach and is quite effective, most of the times it follows “Divide and Conquer”. Work divided among the development and operation teams.
Team SizeAgile believes in “smaller and concise”. Smaller the team better it would be to deliver with fewer complexities.DevOps, on the other hand, believes that “bigger is better”.
SchedulingSince Agile teams are short, a predetermined amount of time is there which are sprints. Hardy, it happens that a sprint has lasted longer than a month but often a week long.DevOps, on the other hand, prioritizes reliabilities. It is because of this behavior that they can focus on a long-term schedule that minimizes business disturbances.
ShortcomingsIn Agile, the gap between these teams is bridged in daily scrum calls where all the rollbacks are discussed and resolved with agile-scrum methodologies.DevOps helps to bridge the line between several cross-functional teams (Development, QA, Monitoring, Deployment, Management etc.) by simplifying the process.
AdvantagesCustomer satisfaction is there as there is the short and continuous delivery of small chunks of working applications.People and interactions are preferred over process and tools.Working software is delivered at frequent timings.Daily interaction among business people and developers.Late changes are welcomed.Agile prefers face to face communication over any other medium.Faster solutionsImproved performancesIncreased efficiencyContinuous improvementImproved customer experience.Faster ROIReduced failures and rollbacks.
DisadvantagesIf there are some big projects, there can be issues in handling the efforts required at the initial stages of developments.The project can get out of track if the client or the representatives are not clear with there needs.No place for a newbie as the Agile works is based on the level of expertise. So there are lesser chances for newcomers.Infrastructure changesNo control over the evolution of the products that the services depend.A Complexity level in some instances has a steep curve. These can be in terms of cost, performances, deployment, and Operations.

Note – there are several other practices that can be performed. The listed are the best just because they fit almost all the development scenarios (mentioned under each).

Conclusion

Agile and DevOps are distinct, although their similarities lead people to think they are on and the same. This does both agile and DevOps a disservice. Agile and DevOps are not adversarial in any way (or at least the intent is not there). They are more allies than enemies in the agile revolution. Agile and DevOps can operate exclusively and inclusively, which allows both to exist in the same space.
