Learn gRPC with online courses and programs

gRPC is a modern framework for building fast, scalable APIs. With the Go programming language and gRPC, you can write .proto files, generate code, and implement services and servers across languages and platforms.

What is gRPC?

Google’s gRPC is a modern, open-source, and high-performance Remote Procedure Call (RPC) framework. An RPC is a software communication protocol. With it, you can access services and processes from a remote computer to use on a local one. gRPC is a more advanced version of RPC that can run in any environment. You can use it when:

  • Building a low-latency, highly scalable distributed system

  • Developing for mobile clients who communicate with a cloud server

  • Designing a new protocol for accuracy, efficiency, and language independence

  • Programming extensions for authentication, load balancing, logging, and monitoring

gRPC web applications have become a popular framework for communication because they're integral to microservices architecture, which allow for faster app development.Footnote 1 They’re also implemented on top of HTTP2 and based on binary coding protocol buffers, a method for serializing data.

What is covered in a gRPC tutorial?

gRPCcourses may begin with an introductory overview of gRPC theory, how it works, and why it’s used, followed by a deep dive into protocol buffers’ efficiencies, the differences between APIs built with gRPC as opposed to HTTP, and advanced use cases. After working through a gRPC tutorial based on a real-world gRPC example, learners can delve into project work. This can involve writing gRPC service definitions into .proto files, generating gRPC golang server and client code, as well as troubleshooting security and error handling issues. 

If you’re interested in becoming a developer, architect, programmer, or engineer, you may consider enrolling in a gRPC gateway course. With edX, you can explore a variety of online courses and programs for learners of varying skill levels to brush up on their competencies and advance their careers. 

Explore jobs that use gRPC

Whether you pursue a bachelor’s degree, a master’s degree, or fast-track your skills development with a boot camp program, a gRPC course can help to prepare you for a number of tech jobs and roles such as:

  • Front-end engineers: develop clean, accessible, and modern web applications, libraries, and components. 

  • Back-end engineers: architect APIs to collect backend data from disparate, unstable, or slow sources.

  • Senior web developers: build microservices to facilitate trading, test performance, and scale. 

  • Senior software engineers: build best-in-class customer data platforms and e-commerce websites.

  • Test automation engineers: develop tools for data acquisition, hardware validation, and quality testing. 

  • Full-stack engineers: build event-driven microservices to provide reliable, scalable customer service.

  • Senior technical writers: produce and maintain technical documents for a team of developers. 

  • Mobile developers: rebuild app components, enhance libraries, and implement coding best practices. 

  • Programmers: contribute to system architecture in a networked multi-user environment. 

  • Architects: develop an environment to facilitate real-time messaging between mobile apps and servers.

How to use gRPC 

Whether centered on gRPC Python or gRPC Java, online coding boot camps can form a helpful foundation for learning microservices architecture. Before enrolling in these courses, you may want to develop a basic understanding of protocol buffers and golang. You might also find it helpful to familiarize yourself with cloud computing or data science through a bachelor's degree program in computer science

Knowledge of gRPC can prove useful in a variety of careers and workplaces. Lyft, for instance, uses gRPC to transmit real-time driver locations as they approach customers. A gRPC server sends a continuous stream of messages, serialized in protocol buffers, to the Lyft mobile app. The app then decodes the messages, translating them into a language that the customer can understand.Footnote 2

In another example, Salesforce developers use gRPC to establish a unified company-wide interoperability strategy. In the past, JSON-based integrations have lacked flexibility and required extensive negotiation. By comparison, gRPC’s technical features allow contract-driven development practices and better understanding of the network’s interface. Teams enjoy more flexibility in designing streaming and push notification services through secure HTTP/2.Footnote 3
