Question - Can you name some deployment strategies?

Answer -

Regular release/deployment: releases software to everyone at once, making it available to the general public.
Canary releases: this is a method that reduces the chance of failure by exposing a small portion of the userbase (around 1%) to the release. With a canary release, developers gradually switch users to the latest release in a controlled way.
Blue-green releases: consists of running two simultaneous instances of an application; one is the stable version currently serving users and the other the latest release. Users are switched from the former to the latter all at once. This method is safer than the regular or big bang releases because users can instantly be routed back to the previous version if there is a problem.
Dark launches: are deployments where new features are released without being announced. Features can be enabled in a very fine-grained way with feature flags.
