Amazon Bedrock AgentCore expands to four new regions and raises runtime quotas to 5,000 sessions

AWS made two coordinated moves to scale its Bedrock AgentCore agent-building platform. First, it raised default runtime quotas to support up to 5,000 active concurrent sessions in US East (N. Virginia) and US West (Oregon), and 2,500 in other supported regions — a meaningful capacity increase for developers running production agent fleets. Second, it expanded AgentCore availability to four new regions: Asia Pacific (Bangkok), Asia Pacific (Malaysia), Europe (Milan), and Europe (Spain).

AgentCore is AWS's platform for building, connecting, and optimizing AI agents with any framework and model, and connecting them to enterprise systems. The quota and region expansion signals real production demand — customers are moving agents from prototype to scale, and hitting concurrency ceilings and data-residency constraints that these changes address.

The timing aligns with AWS's broader agent push this week, including the $1B Forward Deployed Engineering unit and new AgentCore capabilities like structured memory filtering with metadata for multi-agent and multi-tenant architectures, plus a serverless A2A (agent-to-agent) gateway for agent discovery, routing, and access control behind a single domain. Together they position Bedrock as an end-to-end agent operations layer.

Competitively, AWS is racing Google's Gemini Enterprise Agent Platform and Microsoft's Azure agent tooling for enterprise agent workloads, where geographic coverage and data residency are decisive for regulated customers. The European and Asia-Pacific expansion directly targets that. Watch whether AgentCore adoption metrics justify the capacity buildout and how quota limits evolve as multi-agent workloads grow.
