gRPC (gRPC Remote Procedure Calls[1]) is an open source remote procedure call (RPC) system initially developed at Google in 2015.[2] It uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts. It generates cross-platform client and server bindings for many languages. Most common usage scenarios include connecting services in microservices style architecture and connect mobile devices, browser clients to backend services.[3]
gRPC's complex use of HTTP/2 makes it impossible to implement a gRPC client in the browser, instead requiring a proxy.[4]
Authentication
gRPC supports the usage of TLS and token based authentication. Connection to Google services must use TLS. There are two types of credentials: channel credentials and call credentials.[5]
Encoding
gRPC uses protocol buffers to encode the data. Contrary to HTTP APIs with JSON, they have a more strict specification. Due to having a single specification, gRPC eliminates debate and saves developer time because gRPC is consistent across platforms and implementations.[6]
Adoption
A number of different organizations have adopted gRPC, such as Square, Netflix, IBM, CoreOS, Docker, CockroachDB, Cisco, Juniper Networks,[7] Spotify,[8] and Dropbox.[9]
The open source project u-bmc uses gRPC to replace IPMI.[10] On 8 January 2019, Dropbox announced that the next version of "Courier", their RPC framework at the core of their SOA (service oriented architecture), would be migrated to be based on gRPC, primarily because it aligned well with their existing custom RPC frameworks.[11]
