All the examples using SAM have a default Lambda runtime environment
memory size of 512Mb.
Lambda functions run in a microVM defined by its memory size. The memory
size influences the CPU power.
(see
https://docs.aws.amazon.com/lambda/latest/dg/configuration-memory.html)
Increasing memory size increases runtime performance but also increase
costs.
As most of our examples are very simple and small functions, 512Mb
memory is not required. This PR reduces Lambda runtime execution
environment to 128Mb to reduce AWS costs.
