Migrate From Hosted Kafka to Confluent Cloud in the KRaft Era

This post details the technical aspects of migrating from hosted Kafka to Confluent Cloud, focusing on the KRaft era and the role of Kafka Copy Paste (KCP) and Cluster Linking. It explains how KCP simplifies migration planning and provisioning using Terraform, and how Cluster Linking enables byte-for-byte mirroring of topics, preserving partitioning, ordering, and offsets. The post also touches on the underlying mechanisms of Cluster Linking for continuous data propagation, error handling, and its application in global and hybrid cloud scenarios. It highlights cost savings through features like Kora, Private Network Interface (PNI), and Freight clusters, and emphasizes the reliability benefits of Confluent Cloud's 99.99% uptime SLA.
