It also maintains persistent stateful connection. WebSockets is based on HTTP1.1 protocol and it also came to support bi-directional communication which was not supported in the plain version of HTTP 1.1. Otherwise, we normally offload inside the Kubernetes cluster to make it simple and fast for the performance in communication. The other drawback was redundant data which led to performance impact. I know that we can configure HTTP/2 with REST on the Kestrel as well, but it comes with a cost and ineffective because we need to maintain the cert in Kestrel. In all, there are many aspects in the choice of HTTP/2+JSON vs gRPC, it all depends on whats the most important aspect for your use case. Refresh the page, check Medium ’s site status, or. Fewer details is left to the developer to take care of. REST Performance Comparison by Dilem Gner Ayyldz Trendyol Tech Medium 500 Apologies, but something went wrong on our end. And the whole communication inside the Kubernetes is all about gRPC because of power that we have with HTTP/2. gRPC is a higher protocol abstraction than purely using HTTP/2. I usually use REST communication in outside communication with the external world such as external service integration, communication with front-end.
GRPC VS HTTP BENCHMARK DRIVER
Background gRPC performance testing requires a test driver and workers (one or more clients and a server), as described in gRPC performance benchmarks. It use protocol buffers for serializing structured data. gRPC performance benchmarks have now been transitioned to run on GKE, with similar results but much increased flexibility. Fewer details is left to the developer to take care of. gRPC is a high performant framework to exchange message for remote procedure call. What I'm going to say is we need the appropriate strategy for using what kind of protocol with your business cases. gRPC is a higher protocol abstraction than purely using HTTP/2. I'm not saying which one is better than another. NET Team makes a huge difference when dealing with small data in the payload of the message, but actually with the large payload of data, the different has gone. gRPC for example makes it possible to turn-off message compression. gRPC makes better use of HTTP/2 then REST. REST when we deal with the big chunk of data. gRPC uses HTTP/2 to support highly performant and scalable API’s and makes use of binary data rather than just text which makes the communication more compact and more efficient. Enter fullscreen mode Exit fullscreen mode This definition is shared between the server and the client, and the client can call the function as if it is calling a function internally.Īn example of a. HTTP/2 is faster and more efficient than HTTP/1. Recently, I have used gRPC and REST in the same host on my project. The outlier was gRPC's service streaming. gRPC is a modern Remote procedure call framework that uses HTTP/2 and a data serializing method for increased performance with communication or storage. Additionally, these trends held for both the single client and ten simultaneous clients cases. GRPC on the other hand defines a set of communication in the form of a function call in a. The results of the Get operation were largely as expected. The goal is to run benchmarks for 2 approaches and compare them. The server responds to the call, usually with a JSON response in the case of APIs. This repository contains 2 equal APIs: gRPC using Protobuf and JSON over HTTP. What exactly is GRPC?Ī REST API consists of an HTTP verb which is called by the client. I needed some convincing myself that GRPC is indeed higher in performance and it is worth the additional effort it takes to implement GRPC.
Quoting from its website, GRPC is “a high-performance, open-source universal RPC framework”.
