Summary

Serverless computing is becoming the next generation of cloud computing.
Real-world serverless characterization reported that 54% of the serverless applications contain only one function, and 50% of the functions execute less than 1 seconds; hence serverless applications are extremely sensitive to the service latency. To match the invocation rate, the cloud serverless platform automatically scales the function instances to be executed in parallel on available resources.

Although we apply software optimization propoed by previous studies, the end-to-end latency of invoking an enclave function is still far from satisfactory. We further revisit Intel SGX hardware design, and conclude that the root cause for the inefficienty ecnclave-based serverless is that current SGX desgin disables memory sharing between enclave instances.
