CONCEPTS

• Monitoring is the process of collecting and analyzing data to identify and solve problems in an application or system. It is crucial in DevOps to ensure the reliability and performance of applications.

• Microservices are a software architecture style that breaks down an application into loosely coupled services, enabling faster development, deployment, scalability, and reliability.

• Continuous deployment is the automatic deployment of code changes to production as soon as they are ready, allowing for rapid and reliable releases.

• Continuous delivery automates the process of delivering code changes to production, allowing for staging in a production-like environment before deployment.

• Continuous integration merges code changes into a shared repository regularly, facilitating early error detection and compatibility. Logging records events in an application or system, aiding troubleshooting and understanding behavior.

• Quality assurance ensures applications meet quality standards.

• A deployment pipeline is a set of steps for deploying an application to production, which can be automated for reliability and repeatability.

• Effective communication is essential for successful DevOps, enabling collaboration and problem-solving.

• Continuous feedback gathers feedback from users and stakeholders regularly, ensuring applications meet user needs and align with business goals.

• Infrastructure as code manages infrastructure using code, enabling automation and repeatable deployment.

• Observability understands application behavior for troubleshooting and reliability.

• Canary release deploys a new version of an application to a small subset of users before full deployment, reducing the risk of errors.

• Blue-green deployment is a technique where two identical versions of an application are deployed to production. The new version is switched over to production once it has been verified. This ensures no downtime during deployment.
