Cloud-Native Kafka Architecture: Evolution from Layered Storage to a Diskless Future
The article outlines the evolution of Apache Kafka from a traditional hardware-bound design to a cloud-native, highly decoupled architecture. The core focus is on changes in storage models (such as KIP-405 tiered storage), cost control (economic operating system), and solving practical engineering problems like consumer rebalancing, multi-tenancy isolation, and storage cost attribution, pointing out the key trade-offs architects face when choosing storage strategies.
