Adding a Standard Bucket Policy
It is good practice to deny traffic that is not HTTPS to your S3 bucket. For this reason, I wrote a script that I can use to apply a standard policy to each of my S3 buckets. While the script could be more robust to iterate through each bucket in my account, I decided to…

Security Group ID Finder

Pandas & NumPy with AWS Lambda
Fun fact: Pandas and NumPy don’t work out of the box with Lambda. The libraries that you might download from your development machine probably won’t work either. The standard Lambda Python environment is very barebones by default. There is no point in loading in a bunch of libraries if they aren’t needed. This is why…
