Multi-Region Kafka using Synchronous Replication for Disaster Recovery with Zero Data Loss (RPO=0)

Apache Kafka is the backbone of real-time data streaming. Choosing the right deployment model – self-managed, fully managed, or bring-your-own-cloud (BYOC) – is a strategic decision. It affects performance, compliance, and cost. This article explains the most common Kafka deployment strategies and highlights the innovation of synchronous multi-region replication to achieve zero data loss (RPO=0). Alternatives like stretched Kafka clusters, Confluent Multi-Region Clusters (MRC), and WarpStream offer different paths to RPO=0. They support critical workloads with strong durability and high availability. For mission critical and regulated use cases, zero data loss is no longer a future goal. It is now achievable with the right architecture.

Why Tiered Storage for Apache Kafka is a BIG THING…

Apache Kafka added Tiered Storage to separate compute and storage. The capability enables more scalable, reliable and cost-efficient enterprise architectures. This blog post explores the architecture, use cases, benefits, and a case study for storing Petabytes of data in the Kafka commit log. The end discusses why Tiered Storage does NOT replace other databases and how Apache Iceberg might change future Kafka architectures even more.
