I’m thinking in creating some serverless services using a RDS database (Aurora) but I don’t find much information and I have some concerns about performance.
My initial decision was to use a DynamoDB because it’s easy to implement and integrate with Lambda, but I think for the data model I need a relational database would work better, but it seems harder to implement and with some caveats.
- Will I have problems with cold starts and having to start a new database connection?
- Will I have performance problems because I’m running lambda inside a VPC?
- A RDS database is not a good use case for Lambdas?
