You can now retrieve more metric data from Amazon CloudWatch, faster. The quota for the bulk metric retrieval service GetMetricData has increased from 100 to 500 metrics per request. Additionally, the datapoints per second (DPS) quota for retrieving data more than 3 hours old has been increased from 90,000 to 396,000.

AWS Site-to-Site Virtual Private Network (AWS Site-to-Site VPN) now supports digital certificates for Internet Key Exchange (IKE) authentication for VPN connections to an AWS Transit Gateway. This enables you to take advantage of the added security and flexibility that digital certificates offer, for all Site-to-Site VPN connections.  

You can now use Amazon CloudWatch cross-account cross-region dashboards in AWS GovCloud (US) Regions. Cross-account cross-region dashboards enable you to create high level operational dashboards, with one click drill downs into more specific dashboards in different AWS accounts, without having to log in and out of different accounts or switch AWS Regions. The ability to visualize, aggregate, and summarize performance and operational data across accounts and Regions helps reduce mean time to resolution.

Amazon CloudWatch now supports AWS PrivateLink in the AWS GovCloud (US) Regions. This allows you to privately connect to CloudWatch Metrics and Logs, securely on the AWS network. AWS PrivateLink allows you to privately access services hosted on AWS in a highly available and scalable manner, without using public IPs and without requiring the traffic to traverse the internet.

You can now create Amazon RDS for MySQL and Amazon RDS for MariaDB database instances with up to 64TB of storage when using R5 instance types. Previously, R5 instances supported 16TB of storage. The new storage limit is available when using the Provisioned IOPS (IO1) and General Purpose (GP2) storage types.

Amazon CloudWatch now supports up to five times the number of metrics per graph and dashboard than before — up to 500 metrics per graph (from 100) and 2500 metrics per dashboard (from 500). This allows you to visualize the health and performance of applications that use many individual resources like microservices, containers, or stream-based applications, making it even easier to correlate and identify anomalies at a glance, and reduce time to act.  

Starting today, Amazon EBS crash-consistent snapshot ability is available in Asia Pacific (Osaka) Region. You can now take crash-consistent snapshots across multiple EBS volumes in an EC2 instance with a single API call. Backup data across multiple volumes is in sync and the restore of EBS volumes is accurate. Since snapshots are automatically taken across multiple EBS volumes, you no longer need to stop your instance or coordinate between volumes to ensure crash-consistency.  

Starting today, Amazon Data Lifecycle Manager (DLM) for EBS Snapshots is available in the Asia Pacific (Osaka) Region. Amazon DLM provides a simple, automated way to back up data stored on Amazon EBS volumes. With this feature, you no longer have to rely on custom scripts to create and manage your EBS volume backups.  

Today, AWS Systems Manager introduces the ability to manage Linux instances running on Amazon Elastic Compute Cloud (Amazon EC2) and on-premises using Chef. This new feature enables you to combine the power of Chef recipes with the control and safety benefits provided by Systems Manager. 

Amazon ECS Service Discovery is now available in the Asia Pacific (Hong Kong), Europe (Stockholm), and Middle East (Bahrain) Regions.
