terraform-scheduled-batch-job

A Terraform module representing a scheduled Batch job. Uses a Cloud Watch Event Rule and a Lambda function to submit the Batch job on a cron schedule. Use of the Batch service overcomes two of Lambda's current limitations:

• jobs can run longer than five minutes
• jobs run as containers so they can be written in any language

TODO: Consider including the Batch infrastructure setup inside this module once the Batch Terraform provider is available.
