Deploying Mediasoup-WebRTC application on azure.

Question

Deploying Mediasoup-WebRTC application on azure.

vsi_pranav 161

Hello,

I have a mediasoup-webrtc application for video-streaming which I want to deploy on the Azure infrastructure. Currently I have deployed it on the Azure Virtual Machine Scale Set which is placed behind the Load Balancer. This application requires large number of UDP ports open (for e.g. in our case 3000 UDP ports open) and eventually the rules for these ports must be configured in the load balancer. But it seems load balancer can only allow 300 rules configured which is also a costly solution and hence only 300 users can connect to the streaming, where we want more number of users to connect to the application.

Kindly please suggest a good way and infrastructure to deploy the application.

Unfortunately Azure Load Balancer can only specify one inbound port per load balancing rule. Each Standard Load Balancer can have up to 1,500 rules but each NIC can only have 300 rules.

Does your application need to both send and receive across 3000 UDP ports? If your VMs only need outbound UDP across 3000 ports, then this should not be an issue with default outbound connectivity.

If you do need inbound load balancing across 3000 UDP ports, then Azure Load Balancer might not be the best load balancing solution for you.

Our application needs inbound as well as outbound connectivity across all 3000 UDP ports. So yes, as you stated the standard public load balancer will not be the best solution for us.

Also, can you suggest some good solution for this? Can it be done using Azure Kubernetes Service or Layer 7 Load balancer Application gateway?

Unfortunately none of these will work for a high port number and UDP. You can try using Azure Traffic Manager to send DNS requests to a variety of computers. You will likely need to look at 3rd party load balancing solutions, or see if your application can change to accommodate the limits of Azure Load Balancer.

By 3rd party load balancing solutions, do you mean Nginx or something like that?

That is correct. Something that can load balance across all of the required UDP Ports.
