'AWS Labmda with backing database performance
Does anyone have any performance metric links or tips & tricks lists for using AWS Lambdas in cooperation with a backing RDMS database (Aurora with MySQL or PostgreSQL background) and/or DocumentDB. I want to use this functionality but I want to get at least some idea of what my performance calculations will need to be to determine whether or not it is feasible for certain operations.
I see things like these:
- https://docs.aws.amazon.com/lambda/latest/dg/configuration-database.html
- https://cloudonaut.io/passwordless-database-authentication-for-aws-lambda
- etc.
However, nothing seems to include performance metrics. Since database authc/authz can be expensive, I want to see what I'm in for. I don't want to blow pricing for concurrent connections out of the water nor have excessive delays when a Lambda needs to access something in some cases.
The issue here is trying to run mostly serverless for some things but understanding that it's simply not the best solution for all scenarios.
