Even a custom development shop like ours often uses a CPaaS solution when our clients need to get to market quickly or require a large range of communication options within their WebRTC application. Vonage’s comprehensive suite of Communication APIs is a definite go-to for us. We even built it into our own SimplyDoc Telehealth Starter Kit.
When choosing your WebRTC application architecture, there are trade-offs between going with a native application against the standard, an open source media server, or using a commercial CPaaS platform. There are, however, some simple rules you can follow to lead you to the right decision for your use case.
