Blue-Green vs Canary Deployment: Which Is the Better Strategy for Software Development?

What is blue-green deployment and canary deployment?

Choose the correct definition:

1. Blue-green deployment involves rolling out the new version of an application to a small subset of users first before releasing it to the entire user base.
2. Canary deployment uses two identical production environments to switch traffic between versions after full deployment.

Answer:

The correct definition is: Canary deployment uses two identical production environments to switch traffic between versions after full deployment.

Canary deployment is a strategy used in software development and operations to manage the release of new versions of an application with minimal downtime and risk. This approach involves rolling out the new version of an application to a subset of users first, gradually increasing the rollout if performance is satisfactory.

Canary deployment allows developers to detect any issues early in a controlled manner without affecting all users. By monitoring performance and feedback carefully, developers can ensure a smooth transition to the new version for all users.
