The Problem

The company was already aware of one key requirement, which is an urgency for a very deep architecture at the backend that would be capable of managing and storing Push-to-Talk messages. A very friendly and user-interface front-end was more important; however, the backend had to have deeper as well as performance-oriented complexity architecture. This was what made for the critical challenge—performance would be determined from the backend, and the overall satisfaction from the quality of interactions that users would eventually have amongst themselves would depend on it.

Scalability

The system needed to be highly scalable to support the real-time delivery of millions of voice messages. As the platform continued to grow and attract more users globally, it was crucial that the infrastructure could efficiently handle large traffic loads, ensuring that voice messages could be sent and received in real-time, no matter the volume of concurrent users. This scalability ensured that the system could maintain performance even as the user base expanded significantly.

Efficiency

The delivery of voice messages had to be seamless, with minimal latency to ensure users had a smooth experience when sending and receiving messages. Reducing delays was essential to maintain the real-time communication experience, ensuring that users could connect with others instantly without facing any lag or disruptions. By focusing on efficiency, the platform could provide high-quality, immediate communication, which is a key element of the overall user experience.

Reliability

The backend system had to be designed to handle high levels of concurrent requests without any downtime or errors. Given the platform’s massive user base, it was essential to build a robust and dependable infrastructure capable of managing millions of simultaneous voice message exchanges. Ensuring reliability meant that the system could operate continuously without interruptions, guaranteeing users consistent and uninterrupted communication.

Data Handling

The storage and processing of voice message data needed to be optimized for both efficiency and scalability due to the large volume of messages being exchanged in real-time. The system had to manage these large data sets effectively, storing them in a way that allowed for fast retrieval and processing. Efficient data handling ensured that the platform could maintain a smooth user experience while managing a high volume of data, minimizing any delays or issues related to voice message storage and retrieval.

The Solution

To resolve these challenges, a comprehensive solution was implemented that focused on modernizing systems, automating processes, and improving communication across teams. This approach streamlined operations, reduced inefficiencies, and enhanced the ability to meet customer needs. The solution empowered the business to improve performance, ensure smoother workflows, and stay adaptable to future demands, driving long-term success.

Backend System Design

Developed robust and efficient service for voice message uploading and downloading. Introduced real-time voice data processing to remove lags and enable rich communication.

Automation Deployment

Scripts to be deployed with various configuration files for different environments. This simplifies the process, reduces downtimes on updates, and increases reliability.

Monitoring and Testing

Developed elaborate tracking mechanisms to monitor system performance for advanced indication of potential issues. Wrote unit tests, providing full assurance that the services are reliable on the back-end.

Temporary Storage

Utilized Couchbase NoSQL database to store huge data amounts. Data retrieval and storage were fast, ensuring it worked effectively for a real-time messaging application.

Cloud Integration

Applied AWS solutions like SQS (Simple Queue Service), S3 (Simple Storage Service), and PHP libraries to scale up the project. It provided high availability and fault tolerance, which were the basis for maintaining user trust and satisfaction.

The Result

A high-grade backend system introduced to the Viber platform significantly enhanced its performance and user satisfaction, solidifying Viber’s position as a leader in the telecommunication sector. The project delivered several remarkable results, including the implementation of chunk-based voice messaging, where voice messages were transmitted over keep-alive HTTP connections in one-second chunks. This approach increased data transfer efficiency and improved the responsiveness of the messaging feature. Real-time message delivery was also achieved, ensuring voice messages were transmitted seamlessly, even during periods of high traffic, thereby enhancing reliability. A scalable backend architecture was developed to handle millions of concurrent users, making Viber a standout performer in the telco space. These advancements boosted Viber’s brand equity by elevating its reliability and innovation, fostering a loyal user base that contributed to its growth following Rakuten’s takeover. Additionally, the quality of interactions improved, thanks to intuitive and fast messaging features that engaged and satisfied users.

The introduction and successful implementation of the Push-to-Talk feature on Viber Messenger transformed the platform, delivering an outstanding voice messaging experience to its extensive network of users. This innovation addressed critical challenges related to scalability, efficiency, and reliability while setting a benchmark for the telecommunication industry. Viber’s robust and scalable backend system remains a cutting-edge solution, cementing its reputation as a reliable, innovative, and user-centric communication platform.

Enhancing real-time messaging with cutting-edge backend development for seamless user experience.
