Tutorial Series: DevOps

DevOps is a software development methodology that emphasizes collaboration and communication between development and operations teams to improve the speed and quality of software delivery. DevOps combines practices from software development, such as agile development, with operations practices, such as IT service management, to create a culture of continuous integration, continuous delivery, and continuous deployment.

The goal of DevOps is to streamline the software development and delivery process, reduce errors and delays, and improve the overall quality and reliability of software products. Key practices in DevOps include:

Continuous Integration (CI): The process of continuously building, testing, and integrating code changes into a single shared repository.

Continuous Delivery (CD): The process of automatically releasing new features and updates to customers.

Infrastructure as Code (IaC): The practice of defining and managing infrastructure using code, making it easier to automate and deploy changes.

Automated Testing: The use of automated testing tools to ensure that code changes are functional and do not introduce new errors or bugs.

Monitoring and Feedback: The use of monitoring tools to collect data on software performance and provide feedback to developers for further improvements.
