The Reactive system on Scala and GCP behind CA DyVE, an ad delivery platform

Ad delivery platforms called Demand-side Platforms (DSPs) should respond to 50k req/s of ad auction, moreover, return within 100ms. “CA DyVE”, one of CyberAgent’s DSPs, is designed as a Reactive system utilizing the Google Cloud Platform (GCP) to meet the above tough system requirements.

In this session, I will introduce DSPs using figures and Scala code, mainly on the following items:

• Overall architecture of a Reactive system with elasticity and resiliency
• Cloud component selection for comfortable operation and maintenance (GCP case)
• Choosing between OLTP (online transaction processing), streaming, and batch job depending on the use case
• Utilizing techniques such as Circuit Breaker, Throttling, Bulkhead, and CQRS (Command Query Responsibility Segregation) + Event Sourcing
