EC2 Auto Scaling Gets Batch Termination—Kill 100 Instances in One API Call

AWS just dropped batch instance termination for EC2 Auto Scaling, letting you nuke up to 100 instances with a single TerminateInstanceInAutoScalingGroup API call. Perfect for AI/ML training jobs and event-driven architectures that need to scale down fast—all instances validate atomically before termination, lifecycle hooks stay intact, and it's available everywhere at no extra cost.

Amazon Bedrock Now Routes OpenAI Models Across Regions for Better Performance

Amazon Bedrock just dropped cross-Region inference for OpenAI's GPT-5.6 models (Sol, Terra, Luna), letting you automatically route requests across AWS Regions for higher throughput and lower costs. You can now use Global inference for maximum capacity during traffic spikes, or stick with the new US Geo option to keep data processing within your region—all while using the same APIs (Responses, Converse, Chat Completions) and getting full observability through CloudWatch and Cost Explorer.
