Abstract: Comparing cold-start times, memory isolation guarantees, and execution throughput for multi-tenant agent execution platforms.
To evaluate the real-world communication efficiency of A2ATReady, an industrial-grade testbed was deployed spanning multi-cloud Kubernetes clusters, isolated bare-metal microVMs, and carrier edge nodes. Synthetic multi-agent workloads simulated up to 100,000 concurrent negotiation rounds.
Measurements across 10 million transactions demonstrated that A2ATReady achieved median handshake latencies under 4.8 milliseconds and binary payload serialization under 0.2 milliseconds. Zero schema drift or deserialization faults were observed throughout continuous stress testing.
Implementing A2ATReady within enterprise clusters requires deploying mTLS proxy sidecars, establishing automated rotation of Ed25519 signing keys, and enforcing fine-grained capability scopes to safeguard sensitive internal data stores from adversarial agents.
