What’s Wrong with AWS Lambda at the Edge?

Paranoid Stateful Lambdas (PSL) introduce a federated FaaS framework designed for both cloud and edge environments. By combining Trusted Execution Environments with DataCapsules, PSL ensures secure, stateful execution and efficient inter-enclave communication. The Secure Concurrency Layer (SCL) guarantees security, consistency, and durability, achieving up to 81x higher throughput and significantly lower latency than baseline systems. PSL represents a scalable and practical step forward for secure serverless computing.
