A blue-green deployment is set up for a SAS Micro Analytic Service scoring endpoint. The 'green' environment contains the new model version. What is the final atomic step that completes the deployment?
Select an answer to reveal the explanation.
Short Explanation
Here's the deal — you complete a blue-green deployment by atomically updating the load balancer or API gateway routing rule so all traffic goes to the green endpoint. That switch is instant, and blue stays ready for rollback.
Full Explanation
Atomically updating the load balancer or API gateway routing rule to direct all traffic to the green endpoint completes the deployment. Blue-green deployment is defined by an instantaneous traffic switch at the routing layer, so all requests atomically redirect from blue to green while blue remains available for instant rollback. Gradually shifting traffic in 10% increments over 24 hours describes canary/progressive rollout. Copying the green artifact to blue and restarting blue MAS describes in-place replacement, not blue-green. Running PROC ASTORE on the green model before switching is model preparation, not the deployment switch.
