This week: EC2 enables nested virtualization on virtual instances for KVM and Hyper-V workloads, Aurora now encrypts all new clusters by default, and new HPC8a instances deliver 40% higher performance for compute-intensive workloads. Plus Bedrock adds reinforcement fine-tuning for open-weight models and ACM shortens certificate validity to 198 days.
