    27: Easiest way to encrypt S3-IA and rotate key every 365 days.

    Wouldn’t AWS owned key is a better choice because “AWS KMS automatically rotates AWS managed keys every year (approximately 365 days).”, and free 🤑

    60: Reduce lambda cold start time

    Why is increase memory allocation is the answer? Reference also seem pointing to provisioned concurrency.

    Hello tyzh,

    Thanks for your feedback.

    Could you post a snippet for each question so I can look them up?

    for #27. AWS owned in this context refers to SSE:S3 which does is not rotated every 365 days.
    I’d refer to this link here:

    for #60. When you allocate additional memory, the compute power is also upgraded on the lambda, more compute power equals less time to run the executable

      Hello David,

      Thanks for your feedback.

      Yes, AWS-owned keys are not the same as AWS Managed keys. And you cannot enable nor disable key rotation on AWS-owned keys.

      It is also true that CPU power increases proportionally to the allocated memory for a Lambda function
