Amazon CloudWatch now allows you to use AWS Batch as an event target to run batch computing workloads. Amazon CloudWatch Events enables you to respond quickly to application availability issues or configuration changes that might impact performance or security by notifying you of AWS resource changes in near-real-time. You simply write rules to indicate which events are of interest to your application and what automated action to take when a rule matches an event. You can, for example, invoke AWS Lambda functions or notify an Amazon SNS topic or take an Amazon EBS volume snapshot every hour, or at intervals down to 1-minute. AWS Batch is a fully managed service that automatically provisions compute resources and optimizes the workload distribution based on the volume and resource requirements of submitted jobs. It eliminates the need to install or manage batch computing software. You only pay for the AWS resources (e.g. EC2 instances) you create to store and run your batch jobs.
