A) Create an alias for every new deployed version of the Lambda function. Use the AWS CLI update-alias command with the routing-config parameter to distribute the load.
B) Deploy the application into a new CloudFormation stack. Use an Amazon Route 53 weighted routing policy to distribute the load.
C) Create a version for every new deployed Lambda function. Use the AWS CLI update-function-configuration command with the routing-config parameter to distribute the load.
D) Configure AWS CodeDeploy and use CodeDeployDefault.OneAtATime in the Deployment configuration to distribute the load.

Wait, can you really use CodeDeploy for Lambda? That's surprising!

I disagree, B could work well too with Route 53.

I recall that AWS CodeDeploy can help with canary releases, so option D might be a good choice. But I’m not sure if OneAtATime is the best for Lambda functions.

I practiced a similar question where we had to use routing configurations. I think option C is about creating versions, but I’m not confident about the routing-config part.

I'm not entirely sure, but I feel like deploying a new CloudFormation stack for canary releases might be overkill. Option B seems too complicated for this scenario.

I remember studying canary deployments, and I think using aliases for Lambda functions is a common approach. Option A sounds familiar.

I'm a bit confused here. Transient tables don't persist data, so that doesn't seem like the right choice if the data needs to be reconstructed. Maybe Temporary tables would be better?

I'm a little confused by the question. Are we talking about handling errors in the replication process itself, or dealing with data conflicts? I'll have to think this through carefully before selecting an answer.
