Quickblox WebRTC SDK released

Posted by Alex Bass on February 2, 2015

Today, our super talented Andrey Povelichenko finalised Quickblox’s official Javascript WebRTC SDK. You can now add high quality video and audio calling, using the native WebRTC API, to any webapp, using the same familiar Quickblox Javascript SDK.

What this means is that any user with a webcam or microphone (basically everyone) and a modern browser can initiate a video or audio call with a few clicks – no downloads, no plugins, and no flash! And it’s as simple as QB.webrtc.call . If you’re unfamiliar with WebRTC, you should check out the Google I/O presentation – it’s a very cool technology with a lot of potential. If you are familiar however, you’ll know that a bunch of servers and a pile of filler code is required to get something decent working. Well, as a communication as a service provider, Quickblox already has you covered.

Our WebRTC SDK fits right in with the Javascript SDK – so there’s no new syntax to learn. There are a few buzzwords such as “getUserMedia”, and you’re going to become pretty good friends with the HTML5 <video> element – but after that, the learning curve is small.

You can check out the full WebRTC SDK documentation here, and we invite you to create something awesome!

The key findings from the survey will become available in the form of a free research report in February next year. Aside from contributing to the research, respondents to the survey will also get a chance to win some great prizes, including an iPhone 6, an Oculus Rift DevKit, and a Samsung Gear Smartwatch. You can take the survey here: http://vmob.me/DE1Q15QuickBlox

What are the latest trends in app development you’re seeing? Which platform is the best for monetising your apps? Which is the right revenue model for your apps? Do you think IoT is here to stay or just a fad? Take the survey and contribute to this research :)

Kafka, XMPP Chat, SSL and clustering married together

Posted by Taras Filatov on November 4, 2014

QuickBlox has recently added the support for Kafka (pub-sub queue / messaging system).

We have made our Chat server write to Kafka so that it is easier for our enterprise users to apply analytics, trust & safety and external systems and tools to chat server generated data.

We have also enabled SSL encrypted connection via AWS load balancer so that you can connect Kafka consumers via a secure HTTPS connection.

This solution has been adjusted and tested to work in a scalable environment so that X Kafka brokers can work with Y Chat servers controlled by Z Kafka ZooKeepers. You may also connect multiple consumers if required. This is very useful for backup, analytics and real-time reaction / integration systems.

The configuration depends on architecture and scalability factors but here is an example diagram (clickable) showing the principal scheme.
