![]() ![]() REST, on the other hand, is very broad in application. This removes some control from the developer but results in a continuity of provision for the end developer and end user, which is a potential strength. gRPC is very specific about how you implement it as a framework, and as such, there’s not really a major difference between gRPC implementations. In many cases, its implementation flexibility can be either a weakness or a strength. First, it should be considered that REST is not a hard and fast rule. This creates some balances that are important to consider when implementing either technology. In essence, gRPC and REST may look the same to the end user, but they function fundamentally differently. Whereas RESTful systems are more concerned with data representation for the end user, gRPC is more concerned with surfacing the actual remote procedures. Advantages of REST and gRPCįirstly, it should be noted that REST and gRPC are fundamentally different approaches to the same end-user issue - interacting with remote systems. Notably, the HTTP framework is not a paradigm as in REST, and is instead a specific framework that is controlled and iterated upon by Google and its partners. By utilizing protobufs over HTTP/2, gRPC, in theory, allows any system to make a remote procedure call, regardless of implementation, language, or process, assuming it correctly implements the protobuf itself. A protobuf, or Protocol Buffer, is essentially an interface description language, representing the contract and understanding required for different languages and frameworks to issue a request for a procedure. ![]() GRPC is Google’s framework to allow these remote procedure calls utilizing something called protobufs. In essence, every function on a system can be considered a procedure - when a user utilizes an API to request this procedure be run, we call this a remote procedure call. GRPC, or gRPC Remote Procedure Call, is a cross-platform open-source framework based around the concept of calling procedures on an external system from a remote location. This makes it easier to add additional levels of security and load-balancing for enhanced performance. ![]()
