Tip 1: Packaging of aws-sdk The aws-sdk comes bundled with the Lambda execution environment, but you should not rely on this. Instead you should pack the aws-sdk in your deployment package because: the one in the Lambda execution environment is always a few months old, so probably missing patches, security updates, etc. it’ll introduce difference to what I had tested AWS can update it without notice, so far I haven’t heard of anyone running into issues in Node.

My development background started with C, before turning to Java, and that’s where it stayed. Over time, I realised this was a mistake. You’ve got programming languages that are statically typed, dynamic, compiled, interpreted, object-oriented, procedural, functional and everything in between. Each of them have advantages and disadvantages and use cases where they are most appropriate. Having knowledge of only one is like believing you can solve every problem with a hammer.
