🚀AWS Launches Runtime Instances for Up to 14 Days
Longer sessions, same APIs — what's not to love?
TL;DR
AWS has introduced runtime instances for up to 14 days in Bedrock AgentCore. This feature offers persistent EC2-backed sessions, shared file systems, and GPU support. It's aimed at teams needing longer session durations than microVMs can offer.
AWS just launched runtime instances in Bedrock AgentCore, offering persistent EC2-backed sessions that can run for up to 14 days. This is a big deal for developers who need more extended compute time without the hassle of managing long-term infrastructure. The new feature supports shared file systems and popular agent frameworks like CrewAI and LangGraph, making it easier to bring existing tools into longer-running workflows. Runtime instances are billed at standard EC2 rates plus a management fee, breaking even with microVMs around 24% sustained CPU utilization.
Key Points
Runtime instances provide EC2-backed sessions that can run for up to 14 days, ideal for extended workloads.
Support includes shared file systems, GPU-accelerated instance types, and Python container images.
Agents can collaborate on the same host through a shared session directory without changing packaging models.
Billed at standard EC2 rates plus a management fee; breaks even with microVMs around 24% CPU utilization.
MicroVMs remain default for short, bursty workloads while runtime instances handle long-running tasks.
Why It Matters
If you're running complex workflows that exceed the eight-hour limit of microVMs in AWS Bedrock AgentCore, runtime instances offer persistent EC2-backed sessions up to 14 days. This is a game-changer for teams needing extended compute time without changing their packaging model or infrastructure management approach.
