Diskless Kafka BYOC is a cloud-based architecture that splits storage from compute, delegating replication to cheap object storage and turning Apache Kafka brokers into a stateless compute layer. This approach eliminates inter-AZ replication and local disk storage, reducing costs by up to 80%. BYOC (Bring Your Own Cloud) nails the three Es: Economics, Enforcement, and Enterprise Discounts. It allows customers to control data residency, reduce cloud tolls, and harness enterprise discounts on their cloud bills. Diskless Kafka BYOC is designed for high-scale Kafka workloads, mission-critical applications, and organizations with stringent security requirements. The architecture provides a clear monthly fee, volume-based annual commit, and zero data leaving the house, making it an attractive option for customers who value control, simplicity, and cost-effectiveness.
