What are Symfony’s best practices for ensuring zero-downtime deployments?
Answer: Symfony’s best practices for ensuring zero-downtime deployments include:
1. Use of versioned deployments: Deploy your application in a way that the release is prepared in advance, such as using Git tags or branches.
2. Atomic deployments: Ensure that your deployment is atomic, meaning that it either fully succeeds or fails without leaving the application in an intermediate state.
3. Blue-green deployments: Maintain two identical production environments (blue and green) and switch traffic between them during deployments.
4. Graceful handling of existing requests: Implement mechanisms to finish ongoing requests before taking the old version offline, often through header checks or load balancer configurations.
5. Database migrations: Use non-blocking migrations and consider versioned schema changes to minimize downtime.
6. Caching strategies: Utilize cache warm-up techniques and clear caches in a way that avoids serving stale content to users.
7. Health checks: Implement health endpoints to monitor your application status during and after deployment, ensuring any issues are detected quickly.
These practices collectively minimize disruptions and ensure a seamless user experience during deployments.
