Much hyped architectural pattern CQRS is getting a lot of attention, but it does actually deliver on its promises of managing complexity and scalability, when used with the right abstractions. Casumo, a Malta-based online casino, adopted the principles of CQRS based on these promises. As the company scaled to hundreds of employees and over a hundred services, these promises were put to the challenge.
Allard Buijze and Nakul Mishra discuss the challenges Casumo faced while scaling its system to millions of financial transactions per day and applying event sourcing with billions of events to keep up with the ever-changing demands of the gaming industry.
Allard Buijze is the founder and chief technical officer at AxonIQ, a microservices communication platform for building event-driven, distributed applications, where he helps customers reach appropriate future-proof technical decisions. A former software architect within the fields of scalability and performance, he’s worked on several projects where performance is often a recurring theme. Allard is convinced that a good domain model is the beginning of contributing to the overall performance of an application and developed the Axon framework out of this conviction. He regularly gives workshops and trainings on frameworks, best practices, and architecture and is a frequent speaker at conferences, seminars, and meetups.
Nakul Mishra is a software developer at Casumo focusing on JVM and related technologies. Nakul prefers automation over manual configurations and is keen on continuous delivery, unit testing, and code simplicity. He’s interested in developing applications that require creativity, imagination, fast learning, and a zest for putting theory into code.
