The traditional separation between development and operations teams often leads to delays, communication breakdowns, and quality issues.

A unified team approach where developers are responsible for the entire lifecycle of a system, from development to operations.

A set of practices and philosophies that bridge the gap between development and operations, aiming for faster, higher-quality, and more reliable software delivery.

Breaking down barriers between teams to encourage communication and shared responsibility.

Automating repetitive tasks such as testing, deployment, and monitoring to reduce manual effort and increase efficiency.

Continuously improving processes through iteration and feedback, aiming for higher quality and efficiency.

Real-time monitoring and feedback mechanisms that enable quick detection and resolution of issues.

A core DevOps practice that involves automating the entire software development lifecycle, from code to deployment.

A cycle that represents the iterative nature of software development, encompassing code development, building, testing, integration, and deployment.

DevOps aims to improve the speed, quality, and reliability of software delivery by focusing on collaboration, automation, continuous improvement, and feedback.

The process of capturing and using information from different stages of the DevOps lifecycle to improve future iterations.

A practice that automates tasks to speed up development, reduce errors, and improve consistency.

The ability to automatically merge code changes from different developers, test them, and deploy them to a shared environment.

The process of automatically packaging and deploying software to a test environment that mirrors production conditions.

The practice of automatically deploying software to production as soon as it meets quality standards.

A core principle of DevOps that emphasizes teamwork and collaboration between development, operations, and other teams.

The process of monitoring production environments in real-time to track performance and identify issues.

A key practice in DevOps where tests are automatically executed for each code commit, ensuring code quality and reducing regressions.

A practice where automated security scans are performed on code and applications to identify vulnerabilities.

The idea of integrating security considerations throughout the entire DevOps lifecycle, from planning to deployment.

The DevOps cycle is an iterative, collaborative process with several phases. It emphasizes continuous improvement and prioritizes customer satisfaction.

In the DevOps cycle, "Plan" involves defining project goals, requirements, and deliverables. It includes collaboration with teams and using tools for task management.

The "Develop" phase focuses on writing and refining source code using coding best practices. Version control systems like Git are crucial in this phase.

The "Build" phase involves compiling source code into executable artifacts. Automated tools handle building processes and dependencies.

The "Test" phase ensures the application meets quality standards. Automated tests help validate functionality, performance, and reliability.

The "Release" phase prepares and deploys the application to production. This includes versioning, reviews, and approvals before deployment.

The "Deploy" phase moves the application into the production environment. Containerization and orchestration tools facilitate scalability and zero-downtime deployments.

Blue-green deployment involves running the current version on a 'blue' environment and the new version on a 'green' environment. Users are directed to the new version after testing.

Canary deployment involves releasing the new version to a small subset of users before rolling it out to everyone. This allows for testing and monitoring before wider release.

The "Operate" phase involves maintaining the application in production. This includes monitoring performance, addressing incidents, and minimizing downtime.
