Common deployment patterns and how to use them in Octopus

Deployment patterns are crucial for minimizing downtime and ensuring smooth operations in development pipelines, and Octopus provides structured ways to implement several of these patterns. Rolling deployments involve releasing updates to one target at a time, reducing risks and allowing easy rollbacks, while blue/green deployments use two production environments to facilitate seamless transitions and simple rollbacks at the cost of complexity and expense. Canary deployments introduce changes to a small section of production targets for testing before a wider rollout, allowing early detection of issues. Multi-region deployments extend releases across various geographical locations using a combination of environments, lifecycles, cloud regions, or tenants, which can be customized in Octopus for order and scheduling preferences. Octopus offers detailed processes to set up these patterns, emphasizing automation, role assignments, and variable management to enhance deployment efficiency and reliability.
