Proven: Up to 73% Fewer Brokers With Confluent Private Cloud – and More

This post presents benchmarking data demonstrating Confluent Private Cloud's (CPC) efficiency compared to Apache Kafka (AK). Key findings include: 1) CPC with Intelligent Replication (IR) matches AK's p99 latency with up to 73% fewer brokers, exemplified by a 21-broker AK cluster at 250 MB/s matching CPC's latency with 7 brokers. 2) CPC with IR offers up to 83% lower tail latency on identical infrastructure under heavy load. 3) CPC eliminates the 'latency cliff' seen in AK, showing only a 16% latency increase at peak saturation versus AK's >5x spike. 4) CPC provides exponential savings for large-scale workloads, with up to 73% broker reduction for 14,000 partitions. The post also pre-announces Early Access for CPC Centralized Policy Enforcement, featuring Gateway Field Level Encryption, Gateway Payload Encryption, and Deep Schema Validation, and pre-announces broker-native multi-tenancy for CPC, introducing Logical Kafka Clusters (LKCs) on Physical Kafka Clusters (PKCs) with isolation, quotas, and observability.
