![]() Like an object, a RESTful resource has behaviors and properties. Representational State Transfer (REST) is an architectural style that uses HTTP as the standard communication protocol for dealing with resources defined in an API. A resource can be thought of as an entity similar to an object in object-oriented programming. GRPC users can take advantage of all the features that Protocol Buffers provide, including backward and forward compatibility, multiple languages, and code generation. Protocol Buffers is a language-neutral, platform-neutral, extensible way of serializing structured data for use in communications protocols, data storage, and more. ![]() GRPC contracts are defined using the Protocol Buffers language. Once a contract is defined, gRPC users can generate client and server bindings for that contract in any of gRPC’s supported languages. This contract defines the methods that can be called remotely, the parameters they take, and the data types used for both requests and responses. GRPC is based on the concept of a contract or service definition. It enables client and server applications to communicate transparently and makes it easier to build connected systems. GRPC is a modern open-source remote procedure call (RPC) framework that can run anywhere. Once the RPC library is in place, communication between the two systems can take place using any number of protocols, such as TCP/IP or UDP. RPC is a powerful tool for building distributed applications, and its popularity is only likely to continue to grow in the years to come. This library is typically provided by the operating system or an application programming interface (API). ![]() In order for RPC to work, both the client and server must have access to a shared library of code that contains the RPC functions. It is also a popular choice for inter-process communication (IPC), due to its flexibility and efficiency. RPC is used in a wide variety of applications, such as file sharing, printing, and software updates. The server then performs the requested service and returns the results to the client. It is a method of communication between two computer systems in which one system (the client) requests a service from the other system (the server). RPC stands for the remote procedure call. Confused between gRPC and REST? Well, worry not! This article will help break down the key differences between these two popular web service styles.īut before we try to understand the significant difference between two of the most popular API development styles. In terms of throughput, gRPC has also been shown to outperform REST, achieving up to 10x higher throughput in some cases. For example, a recent benchmarking study by Google showed that gRPC was able to achieve up to 60% lower latency than REST for some use cases. In terms of performance, gRPC has been shown to outperform REST in a number of benchmarks. They can be strongly typed and easily integrated into programming languages like Java, Go, Python, etc. This can provide a number of performance benefits such as lower latency and higher throughput. Finally, gRPC services are typically generated from service definitions using tools like protocol. Second, gRPC uses HTTP/2 as its transport protocol, while REST typically uses HTTP/1.1. ![]() First, gRPC uses a binary encoding for its message payloads as opposed to the JSON encoding used by REST. This can result in a more efficient representation of data, especially when dealing with structured data types such as protobufs. Few critical differences between gRPC and REST that are worth highlighting.
