AWS Batch now supports Amazon Elastic Container Service Exec and AWS FireLens log router

AWS Batch now supports Amazon Elastic Container Service (ECS) Exec and AWS FireLens log router for AWS Batch on Amazon ECS and AWS Fargate. With ECS Exec you can track the progress of your application and troubleshoot issue by by running interactive commands against the containers in your AWS Batch job. AWS FireLens allows you to stream logs of your AWS Batch jobs to your chosen destinations including Amazon CloudWatch, Amazon S3, Amazon OpenSearch Service, Amazon Redshift, partner services such as Splunk and more. You can configure ECS Exec and AWS FireLens while registering a new AWS Batch job definition or making a revision to an existing job definition. For more information, see Register Job Definition page in the [AWS Batch API reference](https://docs.aws.amazon.com/batch/latest/APIReference/API%5FRegisterJobDefinition.html) and Amazon ECS Developer Guide for [ECS Exec](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-exec.html) and [AWS FireLens](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/firelens-taskdef.html). AWS Batch supports developers, scientists, and engineers in running efficient batch processing for ML model training, simulations, and analysis at any scale. ECS Exec and AWS FireLens are supported in any [AWS Region](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) where AWS Batch is available.
