What is Agile?

Agile is a software development methodology that focuses on customer collaboration, fast delivery of working software, and delivering the product frequently. Agile was developed in response to the inefficiencies of the traditional, Waterfall-Style Software Development methodologies. Agile methodology is based on adaptability, early involvement of customers, and frequent delivery of working software. Instead of a large project plan that is created upfront and then followed, Agile breaks down the project into smaller, more manageable chunks. Agile also emphasizes the importance of collaboration between the customer and the team, which helps to ensure that the final product meets the customer's needs. Agile also encourages teams to self-organize and continuously inspect and adapt their processes to ensure that they are constantly improving their processes and products.

Benefits of Agile:

• Increased Flexibility : Agile methodology allows teams to respond to change quickly and easily. This means that teams can quickly adapt to changing requirements and customer needs, delivering better results faster.
• Improved Quality : Agile methodology focuses on delivering small increments of work regularly, which allows teams to identify and fix issues much faster than traditional methods. This leads to higher quality products and fewer issues overall.
• Increased Collaboration : Agile methodology encourages collaboration between teams and stakeholders. This makes it easier for teams to share ideas, build consensus, and make better decisions.
• Faster Delivery : Agile methodology allows teams to deliver results faster than traditional methods. This is because teams are focused on delivering small increments of work regularly rather than large, complex projects.
• Improved Visibility : Agile methodology provides visibility into progress and allows teams to track progress in real-time. This makes it easier for teams to identify potential issues and course-correct them as needed.

What is DevOps?

DevOps is an approach for software development that emphasizes collaboration, communication, integration, automation, and measurement of cooperation between software developers and other IT professionals. It is designed to improve the speed and quality of software development and delivery. It also reduces the cost and risk associated with software development.

DevOps is a combination of two words and they are “Development” and “Operations”, So we can say DevOps is a combination of these two to ensure proper communication and collaboration among the development teams. DevOps is focused on automating processes, such as the continuous integration and continuous delivery (CI/CD) of software. It uses a variety of tools and techniques to automate the deployment and testing of applications. It also helps to reduce the risk of software deployment by automating tests for software application stability and performance. It also promotes the scalability of systems, since the automated processes allow for faster and smoother deployments. This increases the ability of organizations to quickly respond to changes in demand.

Benefits of DevOps

• Improved Collaboration : DevOps ensures collaboration between Development and Operations teams. This helps to bridge the gap between them and reduce friction.
• Increased Efficiency : DevOps automates many of the manual processes and hence it helps to improve efficiency and speeds up the delivery process.
• Improved Quality : Automation in DevOps helps to reduce human errors and improves the quality of the software product.
• Faster Delivery : It helps to automate the entire process from the development level to production. The process of developing and deploying software is streamlined. This helps to reduce the time to market and deliver the product faster.
• Cost Savings : DevOps reduces manual efforts and hence helps to save costs. It also helps to reduce the time and cost associated with the project.
• Improved Security : DevOps helps to improve the security of the product by automating the security measures. This helps to reduce the chances of security breaches in software.

How to do DevOps and Agile Interrelate with Each Other?

DevOps and Agile share a strong interconnection. So the answer of How do Agile and DevOps Interrelate? is, Agile is used to control software development while DevOps focuses on bringing the code into production and automation enhances the process. We can see that they both are different based on their approaches but they also aim for the same thing and that is: Effective Software Development and Delivery of Products High Quality. Software Development teams can speed up their development process by combining Agile Sprins with DevOps Automation. This will also improve the quality of the product. Let's look into some key points given below on How do DevOps and Agile interrelate with Each Other?:

• Continuous Integration (CI) : Continuous Integration and Continuous Delivery (or CI/CD) are used by Agile and DevOps to optimize the delivery lifecycle effectively. Agile ensures discrete bits of work that are connected into a coherent whole and on the other hand DevOps automates the code lifecycle to accelerate release deployments of products based on the business needs. They work simultaneously to create a safe, efficient and dependable pipeline. Some examples of CI/CD Tools are Jenkins, BitBucket, GitHub, Circle CI etc.
• Automation : Testing is done in both methodologies DevOps and Agile but in different ways. While Agile ensures specific skills from users to develop testing that assures quality, DevOps automates the repetitive testing using tools and ensures deployment compliance. Some Automation methods are CI, CD, IaC(Infrastructure as Code), Configuration Management, Test Automation etc.
• Modular Design : DevOps uses modular features like Git repositories and on the other hand Agile uses reusable and modular design concepts to create settings that encourage experimentation. DevOps containers are used to assist in the implementation of agile concepts at scale.
• Feedback : In Agile, sprints and scrum which ensure quick input from all stakeholders. In DevOps feedback is facilitated by identifying and automating errors. By using both Agile and DevOps Feedback cycles, the quality of the product increases up to the customer's expectations. JIRA is a tool used for this purpose.
• Development Flow : Agile focuses on the customer, while DevOps focuses on the development process. By combining the two, organizations can ensure that their development process is customer-driven, helping to create a better end product.
