One alternative to REST is gRPC, an open-source remote procedure call framework that runs on the HTTP/2 protocol. Here we look at the advantages offered by gRPC and what use cases it is suited for.

Mar 14, 2016 · Stack Overflow has as great discussion on this HTTP 2.0 versus WebSockets. Additionally, while UWP does support HTTP 2.0, depending on who else consumes your service, other clients may not support it. Using HTTP 2.0, therefore, could reduce the number of supported clients for many applications. Feb 27, 2019 · Similarities vs differences. HTTP Preload and HTTP/2 Push are similar in that they are both mechanisms that preemptively provide the browser with necessary assets before the browser knows that they are even required. However, there does exist a few important differences between Preload and Push. For instance:

Http2 vs websocket

That's not much different from websockets: the client has to initiate a websocket upgrade request before the server can send data across, too. The biggest difference is that, unlike websockets, HTTP/2 defines its own multiplexing semantics: how streams get identifiers and how frames carry the id of the stream they're on.
Nov 19, 2017 · REST vs Websockets — Perf Test. If you do a performance test for REST and Websockets, you may find that Websockets do better when high loads are present. This does not necessarily mean that REST ... The greatest advantage of WebSockets over HTTP2 is that . HTTP/2 works only on Browser Level not Application Level Means that HTTP/2 does not offer any JS API like WebSockets to allow communication and transfer some kind of JSON or other data to server directly from Application (e.g. Website).
Upgrading to a WebSocket connection. By far, the most common use case for upgrading an HTTP connection is to use WebSockets, which are always implemented by upgrading an HTTP or HTTPS connection. Keep in mind that if you're opening a new connection using the WebSocket API, or any library that does WebSockets, most or all of this is done for you ... WebSockets and HTTP2.

Modern improvement of HTTP includes two headers: Keep-Alive, to extend connection time, and Upgrade, to use enhanced protocols such as HTTP2.0 or WebSocket. HTTPS is a secured version of HTTP, that data is exchanged with SSL (Secure Sockets Layer), in a form a encrypted code.
The question of WebSockets vs other HTTP based mechanism comes up fairly often though so now there is a good reference to link to.

Aug 26, 2015 · From draft-hirano-httpbis-websocket-over-http2-01. The draft expired back on February 13, 2015 and I haven’t seen any other significant discussions in this area. At this point there doesn’t appear to be any momentum to come up with a way to leverage HTTP/2 in future versions of the WebSocket protocol.
WebSockets: pros and cons. Pros. WebSockets keeps a unique connection open while eliminating latency problems that arise with Long Polling. WebSockets generally do not use XMLHttpRequest, and as such, headers are not sent every-time we need to get more information from the server. This, in turn, reduces the expensive data loads being sent to ...

Jan 24, 2019 · Websockets. With websockets the connection stays open and it is not just one request response call. First an initial HTTP request is made from the client asking to upgrade to websockets. The server accepts this request by returning a 101 "switching protocols" HTTP status code and then the bi-directional communication is established.
Because websocket opted for a variable length header, it can encode larger frames (up to 2^64-1 bits per frame vs HTTP/2 2^24-1 bits per frame ). So if you need a socket to suck down something fat without a lot of ceremony, like, I don't know, maybe video frames, then websockets might still make sense.

Sep 30, 2019 · WebSockets vs SSE: Which is best? This is largely a question of technical debt, which, rather than being categorically a 'bad thing', can sometimes be leveraged and/ or save time in the short term . WebSockets are undoubtedly more complex and demanding than SSEs, and require a bit of developer input up front.

WebSockets are a particularly good fit when the client cannot anticipate when a change will occur and changes are likely to happen in the short term.HTTP, on the other hand, may be a better fit if the client can predict when changes occur or if they occur infrequently—for example, a resource that changes hourly or changes only after it knows that a related resource is modified.

The modern Internet with its TCP/IP protocol started around 1975 which is astonishing 41 years ago. For the most part of its existence, we used HTTP and it’s successor HTTP/1.1 (version 1.1) to communicate between clients and servers.
