Are PSLs the Next Big Thing After Serverless? Here’s What You Need to Know

Paranoid Stateful Lambdas (PSLs) bring together cloud and edge computing under a secure, serverless framework. By running distributed workers inside trusted enclaves, PSLs guarantee confidentiality, integrity, and consistency across potentially untrusted providers. They combine a Secure Concurrency Layer, in-enclave database, and global routing to enable scalable, stateful execution. While not immune to side-channel attacks, PSLs mark a step forward in secure FaaS by making statefulness and security first-class citizens.
