Blue-green deployment

Deploying updates to a new set of microservices (the "green" deployment), while the old version of the

microservices (the "blue" deployment) remains running.

▪ Rolling deployment

Deploying updates to a subset of the microservices at a time, and then rolling the updates out to the rest

of the microservices over time.

▪ Canary deployment

Deploying updates to a small subset of the microservices, and then gradually rolling the updates out to

the rest of the microservices over time.

▪ A/B testing

Deploying updates to a subset of the microservices, and then comparing the performance of the updated

microservices with the performance of the unmodified microservices.
