Automatic backup of Trello boards to S3 using the AWS CDK — Go Free Range.

▤ Summary

I started off by converting an existing project which backed up our company Trello boards to an AWS S3 bucket. This was originally a relatively simple Ruby script which ran as a cron job on our Linode VPS. At around that time a Ruby runtime had been introduced for AWS Lambda functions, so I decided to give that a go. The former is invoked by a scheduled CloudWatch event and for each Trello board it publishes a message to an SNS Topic using the AWS SDK. The function fetches the JSON blob for the board identified by the SNS message and saves it to an S3 bucket in much the same way as the original script did.
