During Coronatime everything went online. If you have been organizing big offline events, now you have to do the same thing online. A year before you simply went to the doctor’s office, now you think twice and use the Telemedicine calling application to consult the doctor first. Education apps flourish online as well. It’s no surprise that video streaming providers like Vonage, Amazon Chime, Twilio are booming. They bill audio/video streaming per minute. And if your business has many customers – you are in $$$ trouble. But sometimes it’s possible to overcome extra expenses. And in this blog post, I will let you know what to do if you need to manage many 1 to 1 video calls or video conferencing in small groups. Quick theory about how most of the video conference system works. We have a server in the middle and every participant connects to the server. It works great, and there is no alternative when you have many users in a room. But, when you have a limited amount of participants in a room or 1 to 1 video call, you can use a different approach. See, there is no server, all participants are connected to each other. How cool is that! As always there are pros and cons of such a system, it’s called “Mesh” by the way. Pros: You don’t need media streaming servers. Cons: You can’t hold many users in such a room. It depends on the video quality and device power, so let’s say 6-8 users is a maximum. Ok, so we have this Mesh approach and it works well for Telemedicine, for Education applications in small groups.
