Export Cloudwatch Logs to AWS S3 – Deploy using SAM

With due reference to the blog which helped me in the right direction, the Tensult blogs article Exporting of AWS CloudWatch logs to S3 using Automation, though at some points I have deviated from the original author’s suggestion.

Some points are blindly my preference and some other due to the suggested best practices. I do agree that starters, would be better off with setting IAM policies with ‘*’ in the resource field. But when you move things into production it is recommended to use least required permissions. Also, some critical policies were missing from the assume role policy. Another unnecessary activity was the checking of the existence of s3 bucket and attempt to create if not exists, at each repeated execution. Again for this purpose the lambda role needed create bucket permission. All these were over my head, and the outcome is this article.

Well if you need CloudWatch logs to be exported to S3 for whatever reason, this could save your time a lot, though this needs to be run in every different region where you need to deploy the stack. Please excuse me as the whole article expects to have aws-cli and sam-cli pre-installed.

Podcasting Solution on AWS

PodCasting – on AWS can be damn cheap while being ready for a bigbillion hit…


  1. Amazon S3
  2. Amazon Lambda ( S3 Events [and @ Edge ( if not authenticating from Cognito) ] )
  3. Amazon CloudFront
  4. Amazon Route 53
  5. Amazon Cognito ( optional if social login is required )
  6. A pinch of html and some javascript ( will be provided by me )

S3 stores raw files in one bucket, and trigers lambda to do the transcoding, if mobile from any format to mp3. Meta information should be uploaded to same bucket as flat file. Also multiple quality files will be generated. Interface will upload meta.json and pod.raw files to S3 bucket.
