Agile is a methodology focused on lightweight software development cycles, with fast releases, iterations, and continuous improvements; DevOps is an organizational function that combines and integrates development and operations. In short, DevOps might help operationally to execute an agile methodology, but DevOps might also use other methods, even though Agile is among the most used in software development.
|Philosophy||Agile is a software development methodology that emphasizes iterative development, collaboration, and customer feedback.||DevOps is a cultural and technical movement that focuses on collaboration between development (Dev) and IT operations (Ops) to automate and streamline the software delivery process.|
|Focus||Agile primarily focuses on the development phase of the software lifecycle, with an emphasis on delivering high-quality, incremental releases.||DevOps extends beyond development and includes the entire software delivery pipeline, from development to testing, deployment, and operations.|
|Principles||Agile is guided by the Agile Manifesto, which includes values such as individuals and interactions, working software, customer collaboration, and responding to change.||DevOps is guided by principles like automation, collaboration, continuous integration, continuous delivery, and monitoring.|
|Roles||Agile defines specific roles, such as Scrum Master, Product Owner, and Development Team, to facilitate collaboration and prioritize work.||DevOps promotes cross-functional teams where individuals from development, operations, and other areas work together to achieve common goals.|
|Iterations||Agile uses iterations (sprints) to deliver increments of working software, typically lasting 2-4 weeks, with regular review and adaptation.||DevOps focuses on continuous and automated delivery, reducing the need for fixed iterations.|
|Automation||While automation is encouraged in Agile (e.g., automated testing), it may not cover the entire software delivery pipeline.||DevOps places a strong emphasis on automation for tasks like code deployment, testing, infrastructure provisioning, and monitoring.|
|Feedback||Agile emphasizes frequent customer feedback and collaboration, often through ceremonies like sprint reviews and daily stand-up meetings.||DevOps promotes quick feedback loops through automated testing, continuous monitoring, and real-time reporting.|
|Deployment||Agile may require separate deployment and operations processes, potentially leading to delays in delivering software to production.||DevOps aims to integrate development and operations, allowing for faster and more reliable deployments to production.|
|Culture||Agile encourages a culture of collaboration, openness, and adaptability but does not explicitly address the cultural aspects of operations.||DevOps places a strong emphasis on cultural transformation, fostering a culture of shared responsibility and collaboration between Dev and Ops teams.|
|Tooling||Agile may use various tools for project management, collaboration, and testing, but it does not prescribe specific toolsets.||DevOps often involves a specific set of tools for automation, such as configuration management, continuous integration, and continuous delivery (CI/CD) tools.|
|Scope||Agile focuses on software development methodologies (e.g., Scrum, Kanban) and may not address broader operational concerns.||DevOps encompasses both development and operations, addressing the entire software delivery lifecycle.|
|Use Cases||Agile is well-suited for software development projects that require iterative development, frequent releases, and close customer collaboration.||DevOps is suitable for organizations that aim to improve the speed, quality, and reliability of software delivery by bridging the gap between development and operations.|
