The head of engineering at TopicShare Inc is faced with a major bug in Production that needs to be fixed as soon as possible, but the QA environment is tied up testing version 2.0 and deploying directly to Production would be risky. To address this issue, they use Humanitec to clone their Production environment, test the hotfix, and deploy it to a new environment, which can be easily rolled back if needed. This approach allows for immediate testing without affecting QA or Production environments, and provides flexibility in managing development environments.
