Question

A cloud engineer is implementing a deployment strategy with the following requirements: - At least two environments for production and development must be supported. - Changes in one environment must not impact the other environment. - The highest possible availability must be achieved. Which of the following deployment strategies should the engineer implement?

Options

  • ARolling
  • BBlue-green
  • CIn-place
  • DCanary

Explanation

The blue-green deployment strategy supports multiple environments (e.g., production and development) while ensuring that changes in one environment do not affect the other. It also achieves high availability by keeping two separate versions of the application: - The blue environment represents the current stable version. - The green environment is where the new version is deployed and tested. Once the green environment is verified, traffic is switched over from blue to green with minimal downtime. If issues arise, the deployment can be quickly rolled back by reverting traffic to the blue environment.
