Amazon EC2 supports nested virtualization on virtual Amazon EC2 instances

Starting today, customers can create nested environments within virtualized Amazon EC2 instances. Previously, customers could only create and manage virtual machines inside bare metal EC2 instances. With this launch, customers can create nested virtual machines by running KVM or Hyper-V on virtual EC2 instances. Customers can leverage this capability for use cases such as running emulators for mobile applications, simulating in-vehicle hardware for automobiles, and running Windows Subsystem for Linux on Windows workstations.

Announcing Amazon DocumentDB long-term support (LTS) on 5.0

Starting today, Amazon DocumentDB (with MongoDB compatibility) offers Long-Term Support (LTS) on DocumentDB 5.0, enabling customers to reduce database upgrade frequency and maintenance overhead. LTS versions will receive only critical stability and security patches without introducing new features. To get started, create a new DocumentDB cluster engine version 5.0.0, or patch your existing engine version 5.0.0 cluster during your next maintenance window. Verify you’re running the required Engine Patch Version by connecting to your cluster and running db.runCommand({getEngineVersion: 1}). Ensure you’re running Engine Patch Version 3.0.17983 or later. This LTS release is available in all Amazon Web Services regions where DocumentDB is offered. For more details about DocumentDB LTS, and how to check to see what engine patch version you’re on, refer to the Long-Term Support (LTS) release for Amazon DocumentDB.
