|---|---|---|---|---|
| Deploy | ||||
| Deployment Model |  Fully managed | Fully managed |  Limited automation for Standard brokers; Express brokers are fully managed, but less customizable | Fully managed |
| Provisioning Time | Instant (pre-provisioned) | Tens of minutes | Mixed provisioning: Slow for Standard brokers, faster (but more expensive) for Express | Minutes |
| Operate | ||||
| Operational Overhead | None | Minimal, fully managed |  Standard requires ZooKeeper or KRaft, more maintenance | Minimal, fully managed |
| Schema Registry | Integrated | Integrated | Requires separate AWS Glue service | Requires separate AWS Glue service |
| Maintenance | None | Automated updates, customer-defined maintenance window | Depends: Standard requires manual intervention; Express is automated, but can't control maintenance window | None |
| SLA | 99.9% | 99.99% | 99.9% uptime, exclusions for Apache Kafka | 99.9% uptime, similar exclusions |
| Scale | ||||
| Scalability | Automatic scaling | BYOC supports multi-GB/s write & read throughput, but in defined service tiers | Broker trade-offs: Manual & slow for Standard with partition sprawl issues; Express is faster but higher price-performance | Automatic scaling |
| Performance | Better price-performance across 5K max partitions | Low latency, optimized C++ engine; integrated auto partition balancing | Higher latency, JVM-based Kafka; Standard requires Cruise Control for auto partition rebalancing | Limited to 2.4K partitions |
| Pricing | Pay-go pricing, with $0.10/hour base cost; discounts + expert support via annual commitment | Higher costs for multi-AZ but reduced in single-AZ; BYOC uses existing discounts and committed spend | Tiered Storage costs 3x more than Redpanda, with higher per-instance costs for Express; discounts for large orgs + no cross-AZ fees | Pay-go pricing with $0.75/hour base cost; support staffed by cloud generalists |
| Innovate | ||||
| Data Sovereignty | No control over underlying infrastructure | Full control over infrastructure, BYOC option for compliance on AWS, GCP, Azure | AWS-owned Tiered Storage, MSK not available in GCP or Azure | No control over underlying infrastructure |
| Data Connectors | 200+ Redpanda Connect components, AI-ready, up to 100 managed pipelines | Run managed pipelines, or self-manage Redpanda Conect for 300+ connectors & unlimited pipelines | MSK Connect / Kafka Connect broad ecosystem, but delivered as a separate service | Same MSK Connect ecosystem, but some connector setups are more constrained (IAM-only) |
Why Redpanda Streaming?
Amazon MSK gives you the infrastructure, but it doesn't give you a day off. It’s essentially managed provisioning—meaning you’re still the one manually rebalancing partitions and babysitting brokers, while inheriting all the architectural debt of legacy Kafka. Redpanda is the modern alternative.
Managed Ops, Not Just Instances
MSK leaves the hardest parts of running Kafka—scaling, tuning, and ongoing monitoring—entirely to you. Redpanda’s auto-tuning, self-healing clusters eliminate the "firefighting" and manual rebalancing that eat up your engineering sprints.
Native Lakehouse Integration
Stop paying managing complex ETL silos. Redpanda Iceberg Topics automatically transform streaming data into query-ready Apache Iceberg™ tables and work out-of-the-box with the Iceberg REST catalog on AWS Glue.
Predictable Performance, Zero Jitter
Legacy Kafka is plagued by unpredictable JVM jitter and garbage collection pauses. Redpanda’s thread-per-core architecture delivers predictable sub-10ms tail latencies and handles GB/sec+ workloads on a fraction of the footprint required by MSK.
Support from People Who Know Streaming
AWS support staff are generalists, not streaming specialists. Their SLA even excludes the Kafka data plane itself. Redpanda gives you direct access to streaming engineers with an SLA that covers the actual software, ensuring your mission-critical workloads stay up, not just your VMs.
