In another post, we talked about blue-green deployments. In this one, we’ll learn about another deployment strategy, which shares the same advantages but is less risky and often leads to better insights.

Continuous integration has changed the way we develop software. But a CI environment is different from production, and synthetic tests are not always enough to reveal problems. Some issues only appear when they hit production, and by that time, the damage is already done. Canary deployments allow us to test the waters before jumping in.
