Distributed Services with Go

Goals When Building a Service

Here are the most important goals to aim for when you’re building a networked service—and some info about how gRPC helps you achieve them:

Simplicity

Networked communication is technical and complex. When building our service, we want to focus on the problem it solves rather than the technical minutiae of request-response serialization, and so on. You want to work with APIs that abstract these details away. However, when you need to work at lower levels of abstraction, then you need those levels to be accessible.

On the spectrum of low- to high-level frameworks, in terms of the abstractions you’re working with, gRPC is mid-to-high level. It’s above a framework like Express since gRPC decides how to serialize and ...
