Introduction
When working on a project, software development methodology refers to the systematic processes that must be followed. It’s an amalgamation of design ideals and pragmatic realities that dates back to the dawn of computing. The purpose is to establish a method for software development that is systematic.
Various software development approaches have been established over time to take advantage of available technology and resources. Software development methodologies give a framework for developers to collaborate more effectively as a group. It defines how information is shared within the team and formalizes communication.
DevOps and Agile have become the most sought-after software development methodologies in the past years. To understand these two differences, let’s look at their definitions.
What is DevOps?
The term DevOps comes from a combination of two words: software development and operations. This enables a single team to manage the application lifecycle, including development, testing, deployment, and operations. DevOps assists you in bridging the gap between software developers, quality assurance engineers, and system administrators.
DevOps encourages collaboration between development and operations teams so that code may be sent to production more quickly and in a repeatable manner.
DevOps services aids in increasing the pace with which a business can provide apps and services. It also enables companies to provide better service to their clients and compete more effectively in the market.
What is Agile?
Agile entails continual iteration of development and testing in the SDLC process. Unlike the waterfall model, development and testing are done simultaneously. This software development method emphasizes incremental, iterative, and evolutionary development methods.
It disassembles the product into little bits before reassembling it for final testing. It can be implemented in various ways, including Kanban, XP, and Scrum.
What are the critical differences between DevOps and Agile?
| Key Differences | DevOps | Agile |
|---|---|---|
| What is it? | DevOps is a method of bringing together development and operations teams. | Agile is an iterative methodology that emphasizes teamwork, customer feedback, and short, frequent releases. |
| Purpose | The purpose of DevOps is to manage the entire engineering process from start to finish. | The goal of Agile is to handle large projects. |
| Task | It emphasizes continuous testing and delivery. | It focuses on constant changes. |
| Implementation | DevOps is centered on collaboration; there is no widely agreed structure. | Agile can be applied to various tactical frameworks, including safe, scrum, and sprint. |
| Team Skill Set | DevOps splits and spreads development and operations teams’ skill sets. | Agile development stresses teaching all team members to have a diverse group of talents that are equivalent and equal. |
| Team Size | It incorporates all of the stakeholders, and it has an extensive team size. | There are only a few people on the team. The smaller the group, the fewer people that work on it, and the faster they can move. |
| Duration | The ideal goal is to send code to production every few hours or daily. | Sprints are used to manage agile development. As a result, each sprint takes substantially less than a month. |
| Feedback | The internal team provides feedback. | The feedback team comes from customers. |
| Target Areas | End-to-end business solutions with a quick turnaround. | The target is software development. |
| Shift-Left Principles | It accepts both left and right versions. | It only allows for a shift to the left. |
| Emphasis | The goal of DevOps is to ensure operational and business readiness. | Agile emphasizes the readiness of both functional and non-functional components. |
| Cross-Functional | Development and operational teams are separated in DevOps. As a result, communication is pretty difficult. | Any team member should be able to do whatever is needed to keep the project moving forward. Furthermore, when each team member is capable of performing all tasks, it improves mutual understanding and camaraderie. |
| Communication | Specs and design papers are used in DevOps discussions. For the deployment process to run smoothly, the operational team must have a thorough understanding of the software release and its hardware/network consequences. | Scrum is one of the most popular Agile software development methodologies. A daily scrum meeting is held. |
| Documentation | Process documentation is critical in DevOps since it is used to transmit software to the operational team for deployment. Inadequate documentation has less of an influence on automation. However, it is difficult to impart all of the necessary knowledge in the construction of complicated software. | The working system takes precedence over detailed documentation in the Agile technique. It’s perfect if you’re adaptable and quick to respond. When you’re trying to hand things over to another team for deployment, though, it might be a pain. |
| Automation | DevOps’ primary purpose is automation. It is based on the notion of maximizing software deployment efficiency. | Agile does not place a high value on automation. It does, however, assist. |
| Goal | It bridges the gap between development and testing and operations. | It bridges the gap between the needs of customers and the development and testing teams. |
| Focus | It is concerned with both functional and nonfunctional readiness. | It puts a greater emphasis on operational and business readiness. |
| Importance | Developing, testing, and implementing are all critical steps. | Agile requires the development of software |
| Speed Vs. Risk | The DevOps method requires teams to ensure that any modifications to the architecture do not pose a risk to the overall project. | Agile teams promote rapid change and a solid application structure. |
| Quality | DevOps, in conjunction with automation and early bug detection, helps to improve quality. To maintain quality standards, developers must adhere to coding and architectural best practices. | Agile results in better application suites that meet the needed specifications. It can readily adapt to changes made in real-time during the project’s life cycle. |
| Tools Used | Puppet, Chef, TeamCity OpenStack and AWS are popular DevOps tools. | JIRA, Bugzilla, and Kanboard are some popular Agile tools. |
| Challenges | To speed labor, the DevOps method requires development, testing, and production environments. | The agile method necessitates a higher level of productivity from teams, which is challenging to meet every time. |
| Advantage | Agile’s release cycle is supported by DevOps. | Agile development allows for a faster development cycle and better defect identification. |
