Agile as well as DevOps are most talked about theories in most of the app development company which are eager to employ within themselves, but there is certainly a confusion as well as overlap between both of them. Only one particular business practice which originated in the field of software development, however, both are being applied for the functions of the organizations way beyond software development.
Using both Agile as well as DevOps together is considered to be the best approach when it comes to affecting the change within any team, department or even the entire organization. The proper understanding of these theories actually means being flexible to how they are effectively changing as well as realizing that there isn’t one particular answer to all the requirements of the organizations.
As the developers of software come to the realization that the immediate drawbacks of processes which are height like Waterfall approach, they searched for approaches which make tweaking the software a lot easier as well as more agile. They also wished to provide a large number of opportunities for the purpose of end-user feedback, to make sure that they are on their right path. In the onset of the 21st century, the Manifesto of Agile software development emerged which codified some of these theories and then placed them under the wholesome umbrella of Agile software development. Also known as Agile, values the following,
- People- They are teammates as well as customers along with the interactions between them rather than tools and processes.
- Immediacy- The Working software rather than a comprehensive documentation
- Flexibility- Responding as well as embracing change rather than following a particular predetermined plan.
Agile also put an end to the notion of the finished product which was essentially the goal of the famed Waterfall approach. Instead, the Agile stressed upon that software development is incremental and iterative. With the new release of the software, the customer can essentially perform different new functions or also improve the existing functions. Agile methodologies also encourage the software developers to break down the entire software development into different pieces essentially are termed as user stories. This actually highlights the entire value of Agile places on any customer which also helps the developers by means of offering faster feedback loops as well as making sure that there is right product alignment with the requirement of the market. Agile also advocates for evolving development, adaptive planning, early as well as continuous delivery as well as continuous improvement such that developers can easily, rapidly along with flexibly respond to different changes the clients require.
Even though Agile was a particular response to the Waterfall methodologies, DevOps wasn’t actually the response to the Agile. These two theories aren’t actually the same thing, until the businesses started seeing the inherent similarities and also increased success as well as productivity when they were used in tandem. As the Information Technology became essential to all of the businesses in this century, the two imperative and popular areas emerged which are, IT Operations (ITOps) as well as Development Operations (DevOps), The inherent responsibilities of ITOps consisted of ensuring security, reliability and compliance while DevOps was responsible for the development and deployment of new products to the particular end users. DevOps walks a fine line between both flexibility as well as rigorous testing along with communication which comes with the deployment of new software.
Agile vs DevOps
Even though there are certain similarities between both Agile and DevOps, there are various differences between them which are mentioned below.
- Speed- Agile is actually about both rapid as well as frequent deployment which is rarely the goal or even mere part of it, for the DevOps.
- Creation vs Deployment- Developing software is actually inherent to Agile, but in the case of DevOps, it is about the appropriate deployment of the software. For outlining the difference, DevOps can easily deploy the software which was actually developed in different approaches which include Agile as well as Non-Agile theories such as Waterfall approaches.
- Specialization- Agile is actually an equal opportunity team where each member of the particular scrum can easily do their job within the team which prevents any type of bottlenecks and slowdowns. In case of DevOps, it assumes separate teams for the purpose of development as well as operations and the people remain within their own teams, but they communicate frequently.
- Documentation and Communication- Daily and regular informal meetings are the centres of Agile approaches such that each member can easily share the progress as well as daily goals and even indicate any help whenever it is needed. These different scrums aren’t meant to go over the entire documentation or metrics and milestones. DevOps entails no daily meeting, but it requires a lot of documentation to communicate the development of the software to all the relevant teams.
- Documentation- Agile teams don’t have to codify their minutes of meetings or any other communications. DevOps require design documents as well as specs to understand the software release fully.
- Size of Team- Staying small is the very basic core of the Agile as the smaller the team is, the fewer people are actually on it, the faster they can easily move even in case they are contributing to a larger amount of effort. DevOps have different teams which work together and then each team can easily as well as realistically practice their own different theories.
- Scheduling- Agile teams actually work in predetermined and short amounts of time also known as sprints. These sprints actually last longer than one month, and they can be as short as a week. However, in the case of DevOps, it values the maximum reliability, so they heavily focus on long-term schedule which minimizes any type of business disruptions.
- Automation- It is the core of DevOps as the overall goal is to actually minimize the disruptions as well as maximize the efficiency especially when it comes to deployment of the software. Agile doesn’t even require any type of automation.
All of these points explain the in-depth differences and contrast between both Agile and DevOps.
