What is DevOps?
What is DevOps?
- A methodology for reducing the time needed for end-users to see changes and making the process less prone to errors.
- A framework for developing software that involves separate teams handling different stages of the IT/maintenance cycle
- A set of practices and tools that enable collaboration, communication, and automation between software development teams and IT operations teams. (correct)
- A tool for automating the process of integrating new changes into an application and deploying/delivering the updated version to production.

Study Notes
- DevOps is a set of practices and tools that enable collaboration, communication, and automation between software development teams and IT operations teams.
- Traditional software development involved separate teams handling different stages of the IT/maintenance cycle, resulting in slower processing times and increased likelihood of errors.
- The DevOps approach reduces the time needed for end-users to see changes and makes the process less prone to errors.
- The DevOps pipeline automates the process of integrating new changes into an application and deploying/delivering the updated version to production.
- Cloud computing services have made it easier to create and maintain these pipelines.
- Frequent deployment of new changes is possible because there are safety mechanisms in place to quickly revert to the previous version if needed.
- YAML files can be used to create any Kubernetes object.
- YAML specifications are stored in a plain text file with the extension .yaml.
- Four mandatory properties (maps) are expected to be included in the YAML file:
apiVersion,kind,metadata, andspec. - In the case of a deployment, the
specproperty includes two required sub-properties:selectorandtemplate.
