Yandex Cloud offers data streaming, real-time analytics, and business logic for managing user accounts. Our work includes calculating and detailing service costs, working with document management systems, and operating payment gateways. We focus on quality code and thorough testing given how user accounts and company revenue depend on us. Our challenges currently include horizontal scaling, fault tolerance, and ACID support in distributed transactions.
With us, you can learn how to build horizontally scalable data processing systems and build a billing system on par with those offered by the largest cloud providers out there.
