Challenge

AppDoc is an e-Health project, that has a purpose of connecting patients and doctors and therefore taking their communications online.

The main goal has been to create a sustainable functional website and a mobile application that would be able to connect doctors and patients, with video calls being one of the main features of the application.

The key features

Plavno created custom system to simplify the creation of projects that offer educational and consulting services that may require video communications functionality. The system may be used to create fully virtual educational projects, e-Health systems, personnel training and many more.
User interface was built as React App which interacts with php based back-end, storing all the user information in MySQL database.
This system is integrated with payment gateways allowing users to pay for their appointments and consultations with credit cards or Paypal accounts.

The AppDoc project is innovative in telemedicine and allows users to receive the necessary medical advice online. Before the appointment, the doctor can examine all the necessary documents and conduct the appointment through the integrated video conference there are share a common core for video calls with the web app, allowing cross-platform calls and chats. Additionally application has a text and voice chat.
AWS CloudFormation to automatize infrastructure setup (IaC solution). As a to let microservices and Kurento communicate asynchronously with node.js via sockets, we adopted SQS message broker, every microservice was deployed as Lamda service and operating in a way of serverless strategy.

Solution

The backend and front-end architecture was developed:

A specially designed call server that allows to scale the service horizontally based on Kurento
Server based video multi-stream recording/transcoding
WebRTC based video-calls on web and mobile
HQ Audio streaming/broadcasting
Chat service

Plavno developed and benchmarked available market products and technologies.

User interface was built as React App which interact with php based back-end, storing all the user information and “call schedules” in MySQL database.

Web Real-Time Communication is a technology that enables Web applications and sites to capture and optionally stream audio and/or video media.

Microservices architecture was chosen to achieve auto scaling of application and meet client requirements, applications supports 200-300 calls simultaneously with recording option enabled and 800-1000 calls without recording.

Video calls and audio transmission are based on low-level platform Kurento and Coturn as TURN relay server (used in a bundle).
