gRPC – The Protocol Of Microservices Joins The Cloud Native Computing Foundation

The Cloud Native Computing Foundation (CNCF) announced that it is adding the gRPC open source protocol to its existing list of projects. The Technical Oversight Committee voted for gRPC, making it the sixth project managed by the foundation.

gRPC was originally developed by Google as an alternative to REST and other RPC protocols. It is designed to be faster and compact than the other protocols typically used in distributed computing. Google has been promoting it as the preferred protocol for developing contemporary, cloud native applications designed as microservices. Many public facing APIs and web services at Google already use gRPC along with REST.

The rise of containerized applications and microservices is resulting in the evolution of technologies optimized for contemporary workloads. gRPC is one such technology that replaces traditional communication protocols used in client/server and web applications. Though REST is extremely popular among developers, it is not designed to be a protocol that can be utilized for internal communication among services. Microservices deployed in environments such as Kubernetes need a high-performance, compact, lightweight protocol for exchanging messages and data. gRPC is a better candidate for such composable, modular applications. Based on HTTP/2 for transport, and a technology called Protocol Buffers for defining the data format, gRPC is designed to be a cross-platform protocol with support for multiple languages. Developers can use gRPC with C++, Java, Python, Go, C#, Ruby, and other mainstream languages.

gRPC is actively used in multiple projects by companies such as CoreOS, Lyft, Netflix, Square, and Cockroach Labs. The most notable open source project to take advantage of this protocol is etcd, a distributed key/value store developed by CoreOS. Kubernetes, Docker, and other successful open source projects rely on etcd and gRPC for cluster management. Many telecom players including Cisco, Juniper, and Arista use gRPC for streaming the telemetry data and network configuration from their devices.
