What is DevOps?

DevOps is a software development method which focuses on communication, integration, and collaboration among IT professionals to enable rapid deployment of products.

DevOps is a culture that promotes collaboration between the Development and Operations Team. This allows deploying code to production faster and in an automated way. It helps to increase an organization’s speed to deliver applications and services. It can be defined as an alignment of development and IT operation.

What is Agile?

Agile Methodology involves continuous iteration of development and testing in the SDLC process. This software development method emphasizes on iterative, incremental, and evolutionary development.

    The Agile development process breaks the product into smaller pieces and integrates them for final testing. It can be implemented in many ways, including scrum, kanban, scrum, XP, etc.

    ParameterAgileDevOps
    What is it?Agile refers to an iterative approach which focuses on collaboration, customer feedback, and small, rapid releases.DevOps is considered a practice of bringing development and operations teams together.
    PurposeAgile helps to manage complex projects.DevOps central concept is to manage end-to-end engineering processes.
    TaskThe Agile process focuses on constant changes.DevOps focuses on constant testing and delivery.
    ImplementationAgile method can be implemented within a range of tactical frzame works like a sprint, safe and scrum.The primary goal of DevOps is to focus on collaboration,so it doesn’t have any commonly accepted framework.
    Team skill setAgile development emphasizes training all team members to have a wide variety of similar and equal skills.DevOps divides and spreads the skill set between the development and operation teams.
    Team sizeSmall Team is at the core of Agile. As smaller is the team, the fewer people on it, the faster they can move.Relatively larger team size as it involves all the stakeholders.
    DurationAgile development is managed in units of “sprints.” This time is much less than a month for each sprint.DevOps strives for deadlines and benchmarks with major releases. The ideal goal is to deliver code to production DAILY or every few hours.
    FeedbackFeedback is given by the customer.Feedback comes from the internal team.
    Target AreasSoftware DevelopmentEnd-to-end business solution and fast delivery.
    Shift-Left PrinciplesLeverage shift-leftLeverage both shifts left and right.
    EmphasisAgile emphasizes on software development methodology for developing software. When the software is developed and released, the agile team will not care what happens to it.DevOps is all about taking software which is ready for release and deploying it in a reliable and secure manner.
    Cross-functionalAny team member should be able to do what’s required for the progress of the project. Also, when each team member can perform every job, it increases understanding and bonding between them.In DevOps, development teams and operational teams are separate. So, communication is quite complex.
    CommunicationScrum is the most common method of implementing Agile software development. Daily scrum meetings are carried out.DevOps communications involve specs and design documents.It’s essential for the operational team to fully understand the software release and its hardware/network implications for adequately running the deployment process.
    DocumentationAgile method is to give priority to the working system over complete documentation. It is ideal when you’re flexible and responsive. However, it can hurt when you’re trying to turn things over to another team for deployment.In the DevOps, process documentation is foremost because it will send the software to the operational team for deployment. Automation minimizes the impact of insufficient documentation. However, in the development of complex software, it’s difficult to transfer all the knowledge required.
    AutomationAgile doesn’t emphasize on automation. Though it helps.Automation is the primary goal of DevOps. It works on the principle to maximize efficiency when deploying software.
    GoalIt addresses the gap between customer need and development & testing teams.It addresses the gap between development + testing and Ops.
    FocusIt focuses on functional and non-function readiness.It focuses more on operational and business readiness.
    ImportanceDeveloping software is inherent to Agile.Developing, testing and implementation all are equally important.
    Speed vs. RiskTeams using Agile support rapid change, and a robust application structure.In the DevOps method, the teams must make sure that the changes which are made to the architecture never develop a risk to the entire project.
    QualityAgile produces better application suites with the desired requirements.It can easily adapt according to the changes made on time,during the project life.DevOps, along with automation and early bug removal, contributes to creating better quality. Developers need to follow Coding and Architectural best practices to maintain quality standards.
    Tools usedJIRA, Bugzilla, Kanboard are some popular Agile tools.Puppet, Chef, TeamCity OpenStack, AWS are popular DevOps tools.
    ChallengesThe agile method needs teams to be more productive which is difficult to match every time.DevOps processes need to development, test and produce environments to streamline work.
    AdvantageAgile offers a shorter development cycle and improved defect detection.DevOps supports Agile’s release cycle.

    • DevOps is a practice of bringing development and operations teams together whereas Agile is an iterative approach that focuses on collaboration, customer feedback and small rapid releases.
    • DevOps focuses on constant testing and delivery while the Agile process focuses on constant changes.
    • DevOps requires a relatively large team while Agile requires a small team.
    • DevOps leverages both shifts left and right principles, on the other hand, Agile leverage shift-left principle.
    • The target area of Agile is Software development whereas the Target area of DevOps is to give end-to-end business solutions and fast delivery.
    • DevOps focuses more on operational and business readiness whereas Agile focuses on functional and non-function readiness.
