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.
