Poster: Reducing Data Movement Tax for Serialization in Microservices

Small-scale public cloud providers cannot adopt serialization data-copy optimizations that leverage hardware acceleration or kernel-bypass zero-copy paradigm (e.g., DPDK) because of (1) accelerator deployment costs, (2) securing kernel-bypass zero-copy serialization communication relies on encryption at the NIC hardware, and (3) kernel-bypass solutions require developers to rewrite the business logic. We propose a serialization library that leverages the kernel scatter-gather communication primitives to reduce serialization data copy costs without using custom hardware or a custom network stack.
