- DevOps engineers may not code the application but should understand the code to make better infrastructure decisions.
- Applications should be maintained using version control, such as Git.
- Code repositories like GitHub or GitLab are essential for collaboration.
- Testing is crucial and can be automated, especially with containers.
- Automation saves time and allows QA engineers to focus on other tasks.
- Continuous Integration involves frequent code commits and automated testing.
- Integration is a crucial phase, where code is committed frequently.
- Even if using off-the-shelf software, adopting Integration practices can speed up deployments.
- Deployment requires attention to hardware, configurations, and management.
- Application Configuration Management and Infrastructure as Code play a role in the DevOps lifecycle.
- Containerization and Kubernetes may be used for efficient deployments.
- Monitoring application performance is essential.
- Feedback from monitoring helps improve application enhancements.
- Reliability, observability, security, and data management should be continuously monitored.
- FinOps teams should be involved to manage cloud costs.
- Operations involve the management and maintenance of the application and infrastructure in the production environment.
- It includes tasks such as monitoring the application's health, handling incidents and outages, ensuring high availability, and managing the infrastructure's performance and scalability.
- DevOps emphasizes the collaboration between development and operations teams to ensure a smooth and efficient deployment process.
- Operations teams work closely with developers to address any issues that arise in the production environment and to ensure the application's ongoing reliability and performanc
- DevOps processes and culture should be adopted across various positions, not limited to a specific "DevOps Engineer" role.
- Positions like Cloud-Native engineer, Cloud architect/engineer, etc., should embrace DevOps practices.
Remember, DevOps is a continuous loop, and the key is to keep enhancing the process over time.
Here are the shortest bullet points for each topic in the DevOps lifecycle:
