gRPC
A high-performance RPC framework using Protocol Buffers — the standard for inter-service communication in microservices architectures.
gRPC is Google's open-source RPC framework built on HTTP/2 and Protocol Buffers. It is significantly faster than REST for inter-service communication due to binary serialization, multiplexed connections, and streaming support. gRPC is the de facto standard for service-to-service communication in large microservices architectures at companies like Netflix, Dropbox, and Square, and is commonly paired with Go, Java, and Python backends.
Typical time to job-readiness: ~4 weeks.
