How to start the L3 blue age workshop and certification

Based on the available information, I don't have specific details about how to start the AWS Blu Age L3 workshop and certification process from the beginning. The sources provided contain information about troubleshooting specific issues that users encountered during different phases of the workshop, such as the "Go Live" step, "Automation" step, and "Execution" step, but they don't outline the initial setup or starting process.

What I can tell you is that the workshop appears to be accessible through the AWS Workshop catalog, and users work through various phases including Automation, Execution/Testing, and Go Live deployment. The workshop involves working with databases, configuring AWS Secrets Manager, packaging applications, and deploying them.

If you're looking to start the L3 certification workshop, I recommend visiting the AWS Workshop catalog or contacting AWS Support for the proper starting point and prerequisites.
