This blog discusses the concepts of DevOps and Agile methodologies in more detail. In this session, we are going to compare various approaches of DevOps and Agile that have been incorporated by many enterprises across the world. This blog mainly focuses on the topics which comprise DevOps and Agile, its advantages, differences, similarities, and other related concepts. Let’s begin by comprehending the terms of DevOps and Agile.
DevOps and Agile have significant variations. DevOps intends to provide more reliable interaction between the development team and the operations team. It doesn’t mean that it proffers a whole strategy for the implementation of the work as such. Instead, it expedites a better interchange of information and tools among the teams and overcomes the incompetence caused otherwise. DevOps also strives to engage automation in every process involved in software development, and we know that automation brings enhanced productivity and cost optimization to any corporation.

Agile is one of the software development methodologies, which concentrates on various short-term development life cycles. Possessing short life cycles enhances the quality of a product. The feedback obtained from consumers is prioritized by the life cycle and permits us to make corresponding changes to the product quicker. Agile has a much smaller life cycle that makes it much more productive than its analogs. It makes the products more comfortable to test, obtain feedback faster, and apprehend the market early.

Even though both procedures promote collaboration to increase speed and efficiency, there are numerous variations while applying the method by which this goal is attained. The following are some critical differences in the Agile vs. DevOps conversation in terms of process, teams, focus and feedback, and tools.
To tell about the team structure. More substantial teams tend to use DevOps, with the skill set distributed among team members within operations and development. Here, each team member has a particular task or set of tasks to finish throughout each level of the process. Agile is more suited for smaller teams to complete work faster. The Agile strategies will not typically prescribe a specific set of tasks to team members but instead inspires all members to share competencies equally. Due to this, all Agile team members can handle or assign any part of a project at any given time.
When it comes to focusing and feedback, Agile and DevOps also vary. While DevOps projects tend to focus on operational and business readiness with most feedback acquired from internal team members, an Agile strategy typically gets the feedback directly from the customers. Concerning focus, Agile teams regularly implement sprints, with each sprint enduring less than a month. With sprints, the achieved tasks are completed following increments, as one sprint starts immediately when the previous sprint finishes. With DevOps, there are specific deadlines to meet and standards to achieve, some of which can occur daily.
Both Agile and DevOps tend to use various tools, depending on the project. The popular project-management tools in Agile include Kanboard and Jira project management software and Bugzilla server software. DevOps uses tools like AWS cloud computing services, Puppet automation software, TeamCity servers, OpenStack software, and Chef infrastructure.
DevOps focuses more on collaboration without having any common framework. It combines all the areas of an enterprise, like operations, development, and testing departments. But Agile applies some tactical frameworks like Scrum. It helps entities speed up their software delivery and enhances productivity.
DevOps aims to send code to production every few hours, but Agile works faster, like a sprint. Agile needs its team to be more productive, and it offers a shorter development cycle. DevOps also does so with an automation process.
In DevOps, building, testing, and applying all are given much importance. It is because it works faster and delivers software solutions on time. But Agile mainly focuses on software development as a primary goal. It doesn't focus on other areas like building, testing, etc., as DevOps does.
DevOps helps to deliver a better quality product with automation by early clearance of bugs. It focuses on faster product delivery with accuracy and contributes to a better quality product. Agile also produces better apps as per need by adapting to the changes much faster. It contains several application suites with required solutions.
Automation is the primary aim of DevOps, so it enhances efficiency. Therefore, it reduces human efforts to execute tasks much faster. But Agile doesn't rely much on the automation process. Using automation can allow QAs to speed up test case creation to run automatically and push the code.
DevOps manages entire engineering processes, but Agile manages more complex projects. Also, DevOps enables IT teams to deploy products more rapidly. Dev and Ops team collaboration allows code deployment to production much faster. Agile breaks the process into small parts and combines them for final testing.
The machine-level thinking is that software apps are very complex to understand. They need many skills and experience to understand the complexity.
DevOps improves the two-way communication between different teams across the organization.
It helps the production work with continuous experimentation and learning of new processes.
Implementation of DevOps ensures faster time to market and delivers products on time, increasing ROI for the business. Cross-functional teams can work collaboratively and can provide solutions much faster.
It balances the workplace by improving the processes across all departments. Different teams can work together, reduce workload stress, and save time.
DevOps helps improve product quality by continuously automating the product delivery process. Thus, teams work much more thoughtfully, deliver good quality products to customers, and get quick feedback.
Automating the various processes saves much time for the team. It helps them to focus on new developments and changes innovatively.
To achieve agility, you must balance the rapid development process, speed, and sequence. It would be best if you also had enhanced reliability with reduced disruption.
DevOps helps continuously develop, test, and deliver new software code improvements using automation tools.
Improving the faster time to market, software quality, enhancing customer satisfaction, and minimizing lifecycle with automation are the major issues that DevOps addresses. It provides more rapid and more reliable solutions to these issues.
DevOps ensures faster production, reduces errors, and enhances the automation process more transparently. It leads to higher productivity and excellent performance.
Automating processes with agility, observing lifecycle performance, timely execution of strategies and product delivery, reducing repetitive work, etc., reduces the cost of production in any business. Thus, DevOps helps very well in reducing time and higher production costs.
Agile offers complete customer satisfaction by developing necessary products that suit the customers. They also take feedback from the stakeholders and customers to make necessary improvements. It leaves customers highly satisfied.
Agile methodologies use an iterative approach that repeatedly improves processes at specific intervals. It continuously focuses on the improvement and Quality of the final product, which helps to deliver superior products.
AgileAgile'sible nature allows the teams to adapt to any change that aligns with the updated goal. All the project deliverables may not comply with the needs or differences. So couples must adjust their work and plans with the change to give quality output.
The Agile team works by simplifying the estimation of costs. They predict the costs for a shorter time and work in a brief period. It also makes it easier for project managers to assess the team's performance and assign resources.
Developers continuously observe the process with better visibility. They also identify the potential errors and resolve them earlier. So, it reduces the risk and improves the chance of product success.
By regular interaction with each other, the Agile teams make sure that everyone is on the same page. They eliminate the confusion in the process and help deliver the final product without issues.
There are some principles mentioned in the Agile manifesto that says:-
It's not necessary to commit to one approach over another. Practicing the combination of both methodologies can increase efficiency. Both these methodologies have significant roles to play with software development and deployment, and one can be used to enable the other.
Teams that implement Agile with or without using DevOps need to remember that the basis for adopting the change should be proficient. The team must possess profound knowledge and precise comprehension of the framework and organize them as part of their software development.
Speaking from the DevOps perspective, the team must assure that the newly incorporated changes must not let any risk pass in. Also, the team has to ensure unseen or transparent changes should not exist, as DevOps is a continuous process and there is scope for numerous changes on board.
Therefore, when implementing DevOps, the team must possess a clear idea of the existing risk with every change being implemented.
The agenda for implementing both Agile and DevOps is to help improve the work efficiency, deliver enhanced applications that are independent of risk. Quality is a critical factor for any business.
Agile produces applications that fit better with the essential requirements and can adapt those changes to respond quickly. Agile designs a workflow that can be adopted as per the changing necessities of the project.DevOps can assist to disclose early bugs and fix it for having improved quality software. Developers have to implement the best coding practices to achieve the expected quality.
Agile and DevOps need to stretch their limits to connect the gaps and to prove efficient. To accomplish this they must adopt the practices and principles of implementing Agile and DevOps practices, for more accelerated development and deliver refined quality software with reduced risks.
Several prominent industries like Walmart, Amazon, Sony, Netflix, etc. practice DevOps to automate all of their processes and build more reliable and smarter products. Even startups, both big and small enterprises like Flipkart, Ola, Grofers, and others, have commenced adopting the DevOps culture into the whole life cycle to enhance the product's quality.
It is hard for a prospered comprehensive corporation to migrate to the Agile methodology, where there are diverse teams already existing for different roles. But if done, it can produce advantages as examined and proven by British Telecoms, National Bank of Canada, Lego, and many others
DevOps cannot be removed or replaced by Agile, both DevOps and Agile methodologies compete with each other. The implementation methodologies reduce the time to execute and streamline the process such that an application moves quickly from deployment to the production area. Enterprises practicing the Agile model implements the process of automated testing and delivers by extending their outlines until the enclosing area. Therefore, both Agile and DevOps don’t stretch their limits, thus enduring in their province.
