Deployment Patterns in Distributed System
Deployment patterns are automated methods for introducing new features to users of an application. The deployment style used can affect how much downtime occurs. Some patterns also allow for the rollout of additional functionality, which lets users test new features with a small group before making them available to everyone.
Deplyment patterns are as follows :
- Blue-green deployment: Two identical environments are created, with one running the current version of the application and the other running the new version. When the new version is ready, the load balancer configuration is changed to switch to the new version.
- Canary deployment: Updates are gradually rolled out to a small group of users, known as the “canary group”. This reduces the risk of introducing a software update in production.
- Rolling deployment: Software updates are gradually rolled out across different servers or clusters, one at a time, while the application remains operational. This allows for a controlled deployment process and makes it easier to roll back if necessary.
- Shadow deployment: The new version is deployed alongside the existing one, but users don’t have immediate access to it. Instead, a copy of requests to the old version is sent to the shadow version for testing.
Distributed System Patterns
Distributed system patterns are abstract ways of structuring a system that helps developers solve recurring design problems. They provide proven solutions that can be reused across different applications and help developers make informed decisions and avoid common pitfalls. In this article, we will see some distributed systems patterns that help designers make robust and efficient systems.
