I while ago I optimized my Screen Saver Gallery API by loading a flat data file into lambda memory. A nightly job selects a random subset of the database and stores it in S3, and the API uses that fil
I use this bash loop to package an AWS SAM template to multiple regions. This script stages the CloudFormation template and assets in a regional bucket. You can share the bucket with other accounts vi
Today I discovered that you can deploy arbitrary files to the CDK staging bucket with a human readable file name! This feature is awesome if you are pre-synthing CDK apps to CloudFormation Templates.

I recently converted a large CDK app to use CDK Pipelines. I LOVE how quickly it was to get working but it generated a UGLY and SLOW pipeline.
To make prebuilt SPA installers with CDK I like to keep environment configuration outside of the minified code via a config.json file. This allows me to build the app once and move it between environments and stages.
Some AWS customers don’t use the CLI, and will not grant an external contractor CLI access. Trying to get access is a waste of time and resources. Do not fear, there is a solution!
