There are a lot of announcements this week which includes:

  • Massive price reduction in EFS Infrequent Access.
  • Port Forwarding is now available using Systems Manager Session Manager.
  • SageMaker Notebooks now export Jupyter logs to CloudWatch.
  • Container Monitoring for Amazon ECS, EKS and Kubernetes are now available in CloudWatch.
  • Amazon Quantum Ledger Database is now in general availability.
  • AWS transfer SFTP now supports logical directories for s3.
  • You can now add additional metadata to Amazon VPC Flow Logs.

EFS IA price reduction

AWS announced a massive price reduction for Elastic File System Infrequent Access (EFS IA). EFS is a fully managed network filesystem for Linux based systems and running on an AWS or on-prem data centre. With the new price reduction, you can now save up to 92% on File storage cost when using EFS Infrequent Access with Lifecycle Management. That is, you can store files for $0.08/ GB per month assuming 20% of your data is actively used and 80% is infrequently accessed.

Port Forwarding using Systems Manager Session Manager

Port Forwarding is now available for Systems Manager Session Manager. Port Forwarding is similar to SSH tunnelling which allows you to establish a secure tunnel between your local machine and remote system to access services which are not exposed to the public internet. You can now create a secure tunnel between your local machine and instances deployed in private subnet without using SSH or configuring Security Groups or a bastion host.

Export Jupyter logs to CloudWatch

Sagemaker notebooks now export Jupyter logs to CloudWatch. SageMaker is a fully managed service that allows you to build, train and deploy machine learning models in AWS. You can now view Sagemaker logs in CloudWatch so you can view events, matrics and health information directly from CloudWatch instead of having to log in to notebook terminal to access the logs. You can also use builtin functionality of CloudWatch to detect anomalies, set alarms and sent automated notifications. Also, it has added benefits that the logs are available even if the notebook instances are offline or unresponsive.

Container Monitoring in CloudWatch

You can now monitor, isolate and diagnose your containerized applications using CloudWatch container insights. This is a great new feature which allows you to view automated dashboards summarizing the performance and health of Elastic Container Service (ECS), Elastic Container Service for Kubernetes (EKS) and Kubernetes clusters by pod, node, namespace, task, container and service. It is easy to troubleshoot infrastructure and performance issues to say what is going on in the container environment.


Amazon Quantum Ledger Databases or QLDB is now in general availability. QLDB, announced and re-invented in 2018, is a fully managed ledger database which provides an immutable history of all committed changes to your data. This history is kept in the form of a journal which cannot be updated, altered or deleted. This is going to be a great solution for the finance industry. It helps to protect the integrity of banking transactions and also for those customers who need to maintain a complete and verifiable audit trail of data changes in an application.

Transfer for SFTP supports logical directories

AWS Transfer SFTP now supports logical directories in S3. Transfer SFTP is a way of transferring files in and out of S3 using secure FTP.  You can now create logical directories structure mapped to your S3 bucket paths and folders and it also allows you to keep your buckets more secure by restricting the use of access to the designated folders they need.

Amazon VPC Flow logs

You can now add additional metadata to Amazon VPC Flow logs. Flow logs allow you to capture information about the IP traffic going into and out from your VPC. So, now you can include additional metadata in your flow logs like VPC-id and subnet-id. It allows you to analyze your VPC flow logs in a more granular way.
