For modern real-time web applications, the ability to send events from the server to the client is indispensable. This necessity has led to the development of several methods over the years, each with its own set of advantages and drawbacks. Initially, long-polling was the only option available. It was then succeeded by WebSockets, which offered a more robust solution for bidirectional communicati

Cloud Run gets WebSockets, HTTP-2 and gRPC bidirectional streams | Google Cloud Blog
Introducing WebSockets, HTTP/2 and gRPC bidirectional streams for Cloud Run We are excited to announce a broad set of new traffic serving capabilities for Cloud Run: end-to-end HTTP/2 connections, WebSockets support, and gRPC bidirectional streaming, completing the types of RPCs that are offered by gRPC. With these capabilities, you can deploy new kinds of applications to Cloud Run that were not p
The future of web-based software architectures is already taking form, and this time it’s server-rendered (again). Papa’s got a brand new bag: HTML-over-WebSockets and broadcast everything all the time. The dual approach of marrying a Single Page App with an API service has left many dev teams mired in endless JSON wrangling and state discrepancy bugs across two layers. This costs dev time, slows

Over the years, the HTTP request-response model has been used for client-server communications in web applications. However, with the popularity of real-time web applications, the need has emerged for servers to be able to push data to clients proactively without having clients requesting it first. As a result, push technology-based communication methods like WebSockets, and Server-Sent Events (SS

webRTCとwebSocketsの違いは何でしょうか？
回答 (3件中の1件目) WebsocketはTCPを利用し、WebRTCはUDPを利用して機能します。 すなわち、信頼性はWebsocketが高く、パフォーマンスはWebRTCが高いです。 また、Websocketはサーバーとクライアントの全二重通信を、WebRTCはピア・ツー・ピアの全二重通信を簡単に実現します。 両者のいいとこ取りをした技術がWebTransportであり、QUICというプロトコルを用いますが、本題から外れますので、回答はここまでとさせていただきます。

WebSockets are a convenient way to create a long-running connection between a server and a client. In an instance where a web client needs to constantly check the server for data, having a REST-based implementation could lead to longer polling times and other related complexities. WebSockets provide a two-way communication stream, allowing pushing of data from the server to the client. Although us
