Arattai, the messaging app from Zoho, illustrates the company’s long-term commitment to technological innovation. Although it appears straightforward at first glance, this app is the result of over two decades of in-house engineering and rigorous research spearheaded by Zoho’s co-founder and Chief Scientist, Sridhar Vembu. Vembu emphasized the depth of the work poured into Arattai, revealing a complex network of underlying frameworks that define its robust infrastructure.
The app benefits from Zoho’s established messaging and audio-video framework, an evolving entity for around 15 years that now serves as a backbone for communication solutions. Moreover, it runs on a highly sophisticated distributed framework that ensures the seamless operation of workloads across various servers and databases. This foundational setup prioritizes fault tolerance, security, and performance tracking—key ingredients that have been meticulously honed within Zoho over the past 20 years.
A Strong Ecosystem Built Through Research
As Sridhar Vembu transitions full-time into research and development, Arattai becomes a focal point for future innovations within Zoho. This shift marks a renewed commitment to pioneering advancements rather than chasing ephemeral growth metrics. The Arattai team itself has received accolades from Vembu, who likens their dedication to that of “rishis,” enlightened sages devoted to their work irrespective of external validation or critique.
Arattai, named after the Tamil word for “chat,” represents Zoho's distinctive Made-in-India approach to messaging applications. It stands as a versatile alternative to international messaging giants, channeling Zoho's philosophy of building technology that emphasizes independence and resilience. This approach unveils Zoho’s strategy of crafting products grounded in research and development, intentionally designed to serve users globally while preserving a uniquely Indian heritage.
The app’s alignment with Zoho’s larger technological ecosystem underscores an intelligent design philosophy where each component is integrated intricately, ensuring that the application evolves continuously with market demands. Arattai is set to play a significant role in Zoho's business model, reflecting a balanced blend of traditional development values and a forward-thinking tech environment.
