AWS Batch now supports customer-ordered instance allocation strategies

AWS Batch Allocation Strategies Update

AWS Batch now offers the Best Fit Progressive Ordered (BFPO) and Spot Capacity Optimized Prioritized (SCOP) allocation strategies, providing enhanced control over instance type prioritization in your compute environments. These strategies allow you to manually define instance type ordering based on your workload-specific performance characteristics.

To utilize these features, specify the BEST_FIT_PROGRESSIVE_ORDERED allocation strategy for your on-demand compute environments or SPOT_CAPACITY_OPTIMIZED_PRIORITIZED for your Amazon EC2 Spot compute environments, and provide an ordered list of instance types or families. These features are accessible via the AWS Batch API (CreateComputeEnvironment or UpdateComputeEnvironment) or the AWS Batch Management Console.

What to do

• Update your compute environments to use the new allocation strategies.
• Review the AWS Batch User Guide for more information.
