Description

Blue-green deployment is a release strategy that uses two identical production environments: one active environment serving users and one inactive environment. A new application version is deployed to the inactive environment and tested before production traffic is redirected to it. If the checks fail, the active environment continues serving traffic. If problems appear after the switch, traffic can quickly be redirected to the previous environment.

During the demo, deployed in Killercoda we will show a simple Continuous Deployment pipeline that:

1. Starts with the current application version running in the active environment.
2. Deploys a new version to the inactive environment.
3. Runs automated health checks against the new version.
4. Switches traffic to the new environment when the checks pass.
5. Demonstrates a failed deployment where health checks prevent a faulty version from receiving traffic.
6. Demonstrates a rollback by redirecting traffic to the previous working environment.

This will allow us to compare successful and unsuccessful deployments and show how blue-green deployment can reduce downtime and deployment risk.

Relevance

Continuous Deployment is an important DevOps practice for releasing changes quickly and safely. This demo illustrates how automated validation, failure handling, traffic switching, and rollback can reduce production downtime and prevent faulty releases from reaching users.

Thank you for the proposal, it looks good but please add a description of what you plan to do in the demo in addition to a description of what blue-green deployments are.

Also, please mark your pull request as ready for review so we can merge it.
