Seven Years of Firecracker

AWS is putting Firecracker microVMs to work in two fresh stacks: AgentCore, the new base layer for AI agents, and Aurora DSQL, a serverless, PostgreSQL-compatible database it just rolled out.

AgentCore gives each agent session its own microVM. More isolation, less cross-talk - solid for multistep LLM workflows packed with tool use.

Aurora DSQL treats each SQL transaction like a pop-up shop. It spins up inside a snapshot-cloned, microVM-based Query Processor. That means faster starts, less memory burn, and clean-page sharing across the board.

Big picture: Firecracker isn’t just for serverless anymore. It’s creeping deeper into compute and databases - fine-grained, fast, and gone when done.
