Agile Vs DevOps – Explanation, Emergence and Difference

Agile Vs DevOps

This article explains the Agile Model and DevOps. Find out the emergence of Agile and DevOps along with a detailed tabular difference between both of them.

Both Agile Methods and DevOps culture have gained tremendous popularity among software engineers and other professionals working in the Information Technology Sector. DevOps is considered to be an extension of the Agile Methodology. Both focus on delivering the product quickly and give extra emphasis on values like ‘teamwork’ and ‘accountability.’ However, there are some distinct differences between these two methods. But, before learning about the differences, let us have a look at their meanings and their emergence.

Agile

The Agile Methodology is a System Development Life Cycle model. The Agile Methodology revolves around the idea of iterative developments where the objective is achieved through the collaboration of different team members. The main aim of the Agile model is to deliver the desired product faster, with better quality. This is achieved through continuous testing and improved collaboration.

Agile

In the Agile development process, the developer’s team breaks down the desired product or the project into several pieces which are integrated for final testing. It is an umbrella framework that includes different subset models like Scrum, Kanban, Lean Software Development, Extreme Programming, etc.

Emergence

The Agile Methodology was made to oppose the rigid and linear Waterfall methodology. Many software engineers and project managers grew fed-up of the severe and direct working style of the Waterfall Model all these led to the emergence of the Agile Model in the late 1990s. There are many differences between the Agile Model and the Waterfall Model, the most notable of them is that unlike the Waterfall Model, testing activities and the development can go hand in hand in the Agile Model. The Agile Model’s primary focus is always on flexibility and continuous improvement with speed, something admired by most of the project managers.

Agile was officially acknowledged in Utah in February 2001 in a meeting between 17 high profile software engineers. Together they published a manifesto for Agile software development, explaining how they have found “better ways of developing software by doing it and helping others do it.” Since then, Agile has been increasingly used in software development across the globe.

DevOps

DevOps is a software development methodology where the development team (Dev) and The Information Technology Operations Team (Ops) work together to deliver a specified product faster and with better quality. As we can guess, by looking at the term, DevOps is derived from the combination of the development team (Dev) and The Information Technology Operations Team (Ops).

DevOps

Historically, the Development Team and Information Technology Operations team used to work separately in different silos. This led to a lack of communication and understanding between these two crucial teams and often ultimately led to product failure or unhappy customers. DevOps’ main objective was to find a suitable solution to these issues. Hence, in DevOps, the scope of ‘lack of communication and understanding between the two teams’ is diminished since both the teams, as well as the Quality Assurance teams, are required to work together. This has led to better efficiency of the organization. The products were quicker to be delivered, and the quality also improved massively.

Emergence

Many experts believe that the concept of DevOps started to catch fire in between 2007 and 2008 when many software communities stood together and complained against a significant flaw in the Information Technology Industry.

The collective fight was against the traditional software development models where the developing team and the IT operations team used to work separately, sometimes on separate floors and even in different buildings. They had independent departmental leadership and often found themselves standing against each other in terms of objectives. This led to the postponement of product delivery and many unhappy customers. And the department used to blame each other for the failure of products. These also led to massive instability within the organization or company.

All these led to the development of the DevOps methodology. A culture where the Development team, IT operations team, and the Quality Assurance team work together with a common goal of faster and high-quality product delivery. So far, DevOps has led to massive success for the organizations implementing this Methodology. There is a sense of unity among the different team members and a responsibility. It also improved relations between the members.

Difference between Agile and DevOps

Agile DevOps
1. Agile is a system development methodology which focuses on collaboration between different teams, customers, stakeholders, management teams, to release the product quickly. DevOps is a software Development methodology where Development and Operations team work together to deliver a high-quality product quickly.
2. As the definition suggests, the main focus of the Agile system is constant changes. In DevOps, the main focus is generally on constant testing a delivery.
3. The Agile method can be executed in different types of frameworks like a sprint, scrum, and kanban. Since the essential goal of DevOps is to bring Development and IT Operations team together and coordinate accordingly, they do not have commonly accepted frameworks.
4. Agile focuses on training each team member to be versatile and have a wide range of skills so that they can handle any task assigned to them. In DevOps, the work is equally divided between the development and IT Operations teams.
5. In Agile, feedback of the customers or the stakeholders is crucial, and decisions are made according to this feedback. In DevOps, the feedback generally comes from the internal team.
6. Agile doesn’t focus on automation. Although, it is understandable that it can help in the developmental software process One of the chief objectives of DevOps operation is automation. It works on the given principles to maximize it’s efficiency when implementing the software.
7. They have a smaller team as compared to DevOps. The less number of people results in better understanding and can deliver the product quickly. In the case of DevOps, the size of the team can be relatively larger since it also involves stakeholders and all the members of the Development and IT Operations teams.
8. Agile addresses the gap between customer needs, testing and development teams DevOps addresses the gap between the Development Team and the IT Operations team.
9. Tools used in Agile Processes are:

  1. Bugzilla
  2. JIRA
  3. Kanboard
  4. Other popular Agile tools
Tools used in DevOps processes are:

  1. Chef
  2. TeamCity
  3. AWS
  4. Open Stacks
  5. Puppet
10. One of the significant challenges faced in Agile development is that it requires all its team members to be highly productive all the time. It is not always possible to meet this requirement. One of the significant challenges faced in DevOps methods is that it needs the development teams, testing teams, and IT operations teams to work simultaneously, which is sometimes difficult to achieve.
11. Agile generally does not focus on cost-cutting and hence may not be the best choice for business. DevOps focuses on Cost-cutting and is considered to be the best choice for business.
