We are using openvidu CE in our meeting platform. Our media server is running on an ec2 c5.2xlarge instance. How many users can we have in a single session (all broadcasting audio and video ). We are looking to be able to support 50 users. Obviously there are client side constraints as to how many streams we can render which we will manage but would still expect the server to handle that many streams. Is this doable using openvidu ? Would the instance size be prohibitive ?
