Rails Deployment Options

• Serial Deployments — tasks run one server at a time.
• Parallel Deployments — tasks run against each server simultaneously.
• Rolling Deployments — tasks are into two separate sets. Each set gets deployed in parallel (all servers at the same time) while the two sets are deployed in serial (one set after the other one). This option is suited for accounts with at least 4 servers and a load balancer.

And there are two types of Rollout strategies available:

• Blue / Green Rollouts — You have the option to serve the latest or previous version of your code to visitors with the immediate or delayed switchover between them.
• Canary Rollouts —The latest version of your code will be visible to a subset of your visitors. Everyone else will see the previous deployment. After deploying you can adjust the rollout percentage as required.

Containerized Apps Deployment Options

• Parallel Deployments — tasks run against each server simultaneously.
• Fast Deployments — services are built and result in images deployed directly to the Kubernetes Cluster.
