New Posts

My wish list for AWS Lambda in 2018. Hot on the heels of the SQS announcement, I came up with a list of features I would love to see from AWS Lambda. Amongst these include:

  • ability to pay for a pool of warm containers & ENIs
  • ability to pipe logs to a Kinesis stream without first going through CloudWatch Logs
  • predicative scaling
  • finalizer handler to clean up resources when a container garbage collected

AWS Announcements

IAM introduces permissions boundaries. This plugs a big gap in the current IAM permission model, where anyone with the permission to create new IAM roles can create more permissive roles than their own. Check out this thread by Ben Kehoe, which accurately summarises the problem as well as limitations with the new feature.

S3 announces increased request rate performance. This is huge, and removes the performance bottleneck with S3 that required us to use randomized keys in the past.
