The early 2000s saw the widespread adoption of the Agile methodology, which changed how we create software and other services. But after a few years of being the standard, a significant gap emerged: the operations team's methods and needs, which delivered and managed software products, were not included in the revolution. This led to the rise of DevOps which integrated the development and operations teams resulting in a much smoother delivery process. However, this also initiated a debate amongst the software community: DevOps vs Agile, which was the superior method?
DevOps and Agile are two distinct but complementary methodologies that focus on the software development and delivery processes respectively. So, which to pick in the battle between DevOps vs Agile? Or do they work best together? This blog aims to make you understand the basic differences and similarities of DevOps vs Agile alongside their key features respectively and correlation. Keep Reading!

What is Agile?
Agile is an iterative software development and project management approach that emphasises teamwork, client feedback, and quick releases. It emerged from the software development sector in the early 2000s, assisting teams in responding to evolving market conditions and client demands.
An Agile approach incorporates some upfront strategy and design, but the development is done in short cycles and with solid stakeholder collaboration. Continual changes are made, and useable versions of products are frequently published more rapidly than those created using the waterfall process. Numerous advantages result from this. The most significant is probably the ability to immediately fix software that doesn't match the demands or expectations of the user.
The four core values of Agile software development are highlighted below:
1) Working software is preferred over thorough documentation
2) Responded by switching over in accordance with a plan
3) Collaboration with the customer during contract negotiations
4) Discussion of the method and tools amongst individuals and teams

What is DevOps?
DevOps is a software development method that allows teams to create, test, and deploy software more quickly and consistently by implementing Agile concepts and practices, such as enhanced automation and more communication between development and operations teams, it can also be termed as DevOps services.
DevOps aims to bridge the gap between operations, who manage the software in production, and developers, who create application software, to build and operate the supporting infrastructure. The obsolete method of building applications by development teams and handing them off to an operations team to deploy and maintain the software with little understanding of how it was created has been replaced by DevOps.
Since 2009, a lot has changed in the software development business, yet the pillars of What is DevOps remain, and those include the following:
1) Cooperation and trust between the Dev and Ops teams
2) Significant reliance on comprehensive software testing procedures
3) Contemporary tool integration to streamline development and operation activities
DevOps vs Agile
The core idea of Agile is to add agility to development. But delivering agility to both development and operations is the core idea behind DevOps. The most crucial aspect to keep in mind is that DevOps does not replace Agile. But it indeed is an advancement and a natural replacement for the Waterfall methodology and other Scrum principles. The obstacles associated with Agile have developed over time, much like how practices improve with time, and DevOps has emerged as the more effective method.
a) DevOps vs Agile: How are Agile and DevOps Different?
|
Basis |
DevOps |
Agile |
|
Definition |
Bringing together development and operations teams is a practise known as DevOps. |
Agile is the name for a continuous iterative method that emphasises customer feedback, teamwork, small, and quick releases. |
|
Purpose |
The goal of DevOps is to manage complete technical processes. |
Managing complicated projects is the goal of Agile. |
|
Task |
It always emphasises delivery and testing. |
It emphasises ongoing developments. |
|
Team size |
Due to the involvement of all stakeholders involved, a large team size is essential. |
The team is not exceptionally large. A smaller team can work more quickly because there are fewer individuals working on it. |
|
Team skillset |
Between the development team and the operation team, DevOps splits and distributes the skill set. |
Agile development places a strong emphasis on equipping all team members with a wide range of equivalent and similar skills. |
|
Implementation |
Since DevOps is based on collaboration, there is no established framework for it. |
A variety of tactical frameworks, including safe, scrum, and sprint, can accommodate Agile implementation. |
|
Duration |
The ideal situation would be to send new code into production every day or every few hours. |
Sprints serve as the management unit for Agile development. Therefore, each sprint will take significantly less time than a month. |
|
Target areas |
Business solution from end to end and quick delivery. |
Software Development |
|
Feedback |
Observations are provided by the internal staff. |
Customer feedback is a key component of Agile. |
|
Focus |
Operational and business readiness are the main goals of DevOps. |
Functional and non-functional readiness is the focus of Agile. |
|
Importance |
Development, testing, and implementation are all equally crucial components of DevOps. |
Agile inherently involves the creation of software. |
|
Quality |
DevOps uses automation and early problem eradication to provide higher-quality work. For upholding quality standards, developers must adhere to best coding and architectural practices. |
Better application suites with the appropriate criteria are produced through Agile. It can easily adapt to timely modifications made over the project. |
|
Documentation |
Since it will transfer the software to an operational team for deployment, the process documentation is crucial in DevOps. Automation lessens the effects of inadequate documentation. However, it might be challenging to impart all the necessary expertise when creating complex software. |
The Agile approach prioritises a functioning system above exhaustive documentation. Being adaptable and responsive is good. However, it may be detrimental if you're seeking to transfer responsibility to another team for deployment. |
|
Communication |
Specifications and design documents are used in DevOps communication. To effectively manage the |

development is scrum. Daily Scrum meetings are held. |
b) DevOps vs Agile: How are Agile and DevOps Similar?
The fundamental distinctions between the Agile and DevOps methodologies have been covered in detail. Let's concentrate on their similarities and determine their relationship to one another:
1) Both Increase Business Productivity: Although Agile and DevOps may take distinct approaches, they are both working toward the same objective, which is to increase corporate efficiency.
Both methods for developing software are incredibly reliable. DevOps accelerates Agile's work, and Agile pushes DevOps to be more intensive.
2) Using Lean philosophies: The Lean idea has been extensively accepted and applied in both Agile and DevOps. This is noticeable, particularly in the communication.
3) The Collaboration Process: Another area where Agile and DevOps share objectives is with subsequent collaboration. The team needs to work together, regardless of the method they use. Every team must further communicate updates on the development process.
How do Agile and DevOps Interrelate?
The integration of Agile and DevOps has several benefits. Some of them are accelerated delivery, improved user satisfaction, and efficient teamwork.
Adapting current tactics and mentalities is necessary to successfully integrate DevOps principles with Agile culture.
Moreover, practitioners of these methodologies have similar mindsets. Furthermore, they have the same objectives.
Agile and DevOps both concur that delivering functional software to customers is the best approach to create software, assure transparency, and encourage sustainable development.
To get software into the hands of customers as quickly as possible, both methodologies encourage development and operations teams to employ modern tools and procedures.
Conclusion
So, to sum up, we can say that DevOps and Agile are not exclusive. Any organisation that is transitioning to DevOps shouldn't eliminate its current Agile workflows. DevOps is an Agile extension based around techniques that are not the main emphasis of Agile. Despite there being a DevOps vs Agile segregation, it is when working together that the two techniques enhance software development and produce higher-quality results.
