PubNub vs SignalR vs Socket.IO

What is PubNub?

PubNub makes it easy for you to add real-time capabilities to your apps, without worrying about the infrastructure. Build apps that allow your users to engage in real-time across mobile, browser, desktop and server.

What is SignalR?

SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.

What is Socket.IO?

Socket.IO enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.

        PubNub is my goto solution for when I want to use sockets at scale. They have redundant data centers in 14 regions with 99.999% SLA allowing me to build realtime apps for any platform. Also Stephen (PubNub CTO) is Awesome!

        I use Socket.IO because using HTTP requests for a real-time multiplayer game just blows! Even with websockets, I had to scrunch the data being transmitted down to a bare minimum, and do some cheap compression tricks so that I can send data in JSON format. Otherwise, I would have to resort to sending binary data. I may end up doing that anyway when the time comes that I need to scale.

        How do I use it? Each client opens a socket connection at startup. The server keeps track of these connections, and sends each client the visible portion of the Playfield repeatedly. The clients render this information, while sending requests and commands to the server (join,turn,fire,thrust,bomb,viewport change,etc.) in response to the player's actions. The server uses that to make adjustments to the player's ship on the Playfield.

        Where we have browser support (recent Chrome, Firefox, and Safari), we make a WebSocket connection so that the server can push changes made by other people down to browsers listening on the appropriate channels. We use a modified version* of the client and server libraries that allows us to keep many thousands of open WebSockets on each of our servers at very little cost in terms of CPU or memory usage. So when anything happens to a board you’re watching, that action is published to our server processes and propagated to your watching browser with very minimal latency, usually well under a second.

        Socket.IO has a decent community footprint, including integrations with popular JS frameworks, and has fallbacks to maintain an app's services if websockets are not available for some reason. Websockets are an important factor in most of the web-facing apps I build, to provide asynchronous two-way communication between the app and whatever server or data source it is connected to.

        Another one that we're not using, yet. But have realtime data updates within our applications and the central API will be a great bit of functionality that gives our clients more control and keep them informed of changes and updates in their stores, in real time.

        Using websockets is something, scaling a message pipeline to thousands of concurrent connections is something else.

        I trust PubNub with what it does best, and use it as ’s messaging pipeline.

        With PubNub, I have one less problem to think about.
