Conclusion

Companies are constantly striving to achieve the best possible products in the least amount of time. This has led to the creation of various methodologies and practices. In this article, we’ll focus on the main two strategies used in the development field. These are DevOps and Agile Methodology. We'll begin by looking into DevOps and what makes it important. After that, we'll unfold its roles and tools. Then, we'll be taking a look at Agile and its key concepts and benefits. Last but not least, we’ll see the similarities and differences between the two of them. Let’s dive in!

What Is DevOps?

DevOps (Development and Operations) is a set of practices developed back in 2008. Its creators are Patrick Debois and Andrew Clay. As a concept, these practices aim to connect Software Development and IT operations. With it, companies are able to deliver superior products with fewer roadblocks. The concepts of Continuous Integration and Continuous Delivery (CI/CD) are key within DevOps. This means teams are always building, testing, and updating changes and updates. As a result, this ensures a high-quality final product.

Why Is DevOps Important?

You now have a general idea of what DevOps is, but why should a team apply these practices? What makes DevOps important? In the past, development and operations teams used to work in separate lanes. In consequence, this led to a blindspot in implementation. If code gets kicked back and forth, there's usually no clear responsible party or course of action. Also, this can contribute to various issues and delays. Yet, when both teams work together, results are not only superior. With joint collaboration throughout a whole life cycle, there are also fewer roadblocks. Nowadays, new software launches faster and faster. As a result, smooth and efficient processes are key to success. Further, DevOps has many other benefits. These include accelerated innovation, improved collaboration, rapid delivery, reliability, security, and scalability.

How Does DevOps Work? The DevOps Process

How Does DevOps Work? The DevOps Process

The concept behind DevOps is quite simple. It combines development and operations in a single team. This way, team members are encouraged to work on cross-functional skills. If you are looking for a simple explanation of the DevOps process, it entails four main stages:

Plan

DevOps teams describe and define the product to be developed's features. Inhere, they organize and schedule tasks.

Develop

In this stage, team members write, test, review, and integrate code.

Deliver

Once the software gets developed, it's deployed into production environments.

Operate

Finally, there's monitoring, maintaining, and troubleshooting within production environments.

If you want a more detailed explanation, one could divide this process into eight steps. These make up the four components of Continuous Integration.

Development: 01. Plan, 02. Code,
Testing: 03. Build, 04. Test,
Deployment: 05. Release, 06. Deploy,
Monitoring: 07. Operate, 08. Monitor.

DevOps' FAQs

Beyond its meaning, there are some questions worth addressing about DevOps. Below, we'll take a look at them.

What Is DevSecOps?

DevSecOps entails integrating security testing and protection into a DevOps model. The traditional security model focuses on checking and correcting security defects before release. Yet, DevSecOps does this in every step of the development process. This leads to faster delivery combined with building secure code.

What Does a DevOps Engineer Do?

A DevOps engineer focuses on finding and implementing processes, methodologies, and tools. These apply to all needs that arise during the software development life cycle. For instance, it covers coding, deployment, maintenance, and updates. DevOps engineers work on unifying and combining development and operations tasks. Besides their technical knowledge, they usually specialize in leadership and team collaboration.

What are the best DevOps tools?

Tools were not an original part of the DevOps model but, over the last few years, many have been developed. These tools make the implementation of these practices more effective. Here are some of the best DevOps tools for each aspect of the process.

Configuration Management: Puppet, Ansible, Chef.
Computing and Storage: AWS, Azure, Google Cloud.
Testing: Sentry, Selenium, Gremlin.
Collaboration: Slack, GitHub.
Coding: JIRA, Eclipse, Git.
Monitoring: Splunk, Nagios, Raygun.
Containerization: Docker, Kubernetes.
Release Tools: Jenkins, Bamboo.

What Is Agile Methodology?

Agile is a project management and software development approach. It's often used for cross-functional teams and focused on iterative development. This means that Agile teams deliver work in small increments. For example, they work in sprints or iterations, including both development and testing. This might ring a bell from DevOps, which revolves around improvements and delivery. This method involves close collaborations. These are often between developers and stakeholders. Also, it offers regular deliveries, frequent inspections, self-organization, and great adaptability to change. Techs and trends are always shifting and evolving. That's why adaptability is essential in the development industry. Also, it's a part of why Agile gains constant popularity.

Agile Methodology Key Concepts

Key Agile Concepts

If Agile comes new to you, there are some key concepts that can be useful to understand. We’ll go over them below.

What's The Agile Manifesto?

The Agile Manifesto identifies the values and principles of this methodology. You can take a look at it here.

What Is Scrum In Agile?

Scrum is an Agile product development framework—i.e., a specific set of practices. Its focus lies on delivering value in the least amount of time. Along with it, work gets organized in sprints, which are iterations that tend to last around two weeks. Each sprint has specific goals to reach within the specified amount of time. Scrum is ideal for cross-functional teams. Also, it works best on projects able to get divided into clearly-defined increments. If you want to learn more about Scrum, you can do so here.

What Is A Sprint Backlog?

In Scrum, a Backlog refers to all the items selected by the team from the product backlog for inclusion in future ones. And, since we’re at it, the Product Backlog includes everything the team needs to work on to finish the product.

What is the Kanban Method?

Kanban is another Agile framework that uses a visual system to organize work. Items are usually represented on a kanban board, which resembles a to-do list. The classic kanban board includes the columns “to do”, “doing” and “done”. This is ideal for teams working on highly-unpredictable projects. That's because it makes it easy to adapt and change priorities. If you want to learn more about Kanban, you can do so here. Although Scrum and Kanban have quite a few differences, there are also hybrid models, as you can see here.

Why use Agile Methodology?

Advantages of Agile are plentiful. Yet, there are some main reasons why companies choose it. These include increasing performance, improving satisfaction, and increasing adaptability. And, as we've seen, adaptability comes essentially in the dev industry. Also, Agile makes it easier for teams to tackle changes during the development process. As a result, this ensures that final products meet specific needs. Other benefits include faster time-to-market, predictable costs, higher quality products, and project transparency.

Agile vs. DevOps: what’s the difference?

Agile vs. DevOps: what’s the difference?

As you might have noticed, Agile and DevOps are quite similar methodologies. They both aim at obtaining a high-quality product as quick as possible. But, what sets them apart? Let's go over some of their differences.

• DevOps bring the development and operations teams—which tend to be apart—together. Moreover, the DevOps team is often large. Meanwhile, Agile focuses on collaboration between developers and product management. Also, it involves smaller teams working together to react to the changing needs of the client.
• DevOps works with hyper-releases and may have several of these every day. Meanwhile, Agile tends to use sprints which can extend from one week to two months.
• DevOps focuses on testing and delivery. Yet, Agile focuses on iterative development and constant changes.
• The Agile process starts with ideation and finishes with code completion. Meanwhile, DevOps goes one step further to include delivery and maintenance.
• DevOps aims to deliver end-to-end business solutions. But, Agile mostly focuses on Software Development.

Like their own different hybrid models, Agile and DevOps can also work together. Teams mix the best of both to deliver faster products while having user needs at the forefront. Yet, given cultural shifts, their implementation should be well thought out. This applies particularly to larger companies.

Conclusion

DevOps and Agile are two excellent models. Both are available for devs to work more efficiently and achieve better results. Moreover, your choice will rely on composition and requirements. In some cases, combining the two might be the right answer. We hope we've given you a comprehensive overview of DevOps and Agile Methodology.
