A factory for creating boto session managers with environment-aware AWS authentication across local, CI/CD, and cloud runtimes.

---

Welcome to which_bsm Documentation

which_bsm is a factory for creating boto session managers with environment-aware AWS authentication across local, CI/CD, and cloud runtimes. It automatically selects the appropriate authentication method based on where your code is running - whether that’s local development with AWS CLI profiles, CI/CD environments using role assumption, or AWS compute services with built-in IAM roles.

The library simplifies multi-environment AWS deployments by providing a single configuration point that adapts to different runtime contexts. You configure your environment topology once, and the system handles authentication complexity automatically.

Key features include lazy-loaded session management, AWS account ID validation, automatic workload role ARN generation for CI environments, and runtime detection across various AWS services (Lambda, Batch, ECS, Glue, EC2) and CI platforms.
