Delivery Guarantees

At-least-once vs. Exactly-once

One of the critical distinctions between Amazon MSK and Kinesis lies in their delivery guarantees. Amazon Kinesis Data Streams provides at-least-once message delivery, ensuring that every record will be processed by the consuming application at least once. This level of guarantee is suitable for scenarios where occasional duplicate records can be tolerated but losing records is unacceptable.

On the other hand, Amazon MSK (Apache Kafka) offers exactly-once message delivery semantics, providing assurance that each record will be delivered exactly once despite changes in system state or failures. This level of guarantee is crucial for use cases where deduplication must be strictly enforced or where maintaining consistency across multiple systems is paramount.

Scalability and Performance

Scaling Mechanisms

When it comes to Amazon MSK and Kinesis, the scalability mechanisms play a crucial role in determining the suitability of each service for specific use cases. Amazon MSK is designed to be highly scalable, capable of handling millions of messages per second. With Amazon MSK provisioned, users can easily scale their Kafka cluster by adding or removing instances (brokers) and storage as needed. The serverless nature of Amazon MSK further simplifies the process by automatically provisioning and scaling capacity while managing the partitions in the topic. This ensures that data can be streamed without the need for extensive considerations about right-sizing or scaling clusters.

On the other hand, Kinesis Data Streams offers its own scaling capabilities, automatically adjusting to varying data volumes. However, it might be better suited for scenarios prioritizing simplicity, integration with other AWS services, and low latency. For workloads with massive capacity changes throughout the day, Kinesis becomes an attractive option due to its cost allocation model and flexibility in handling fluctuations.

Throughput and Latency

In terms of throughput and latency considerations, both Amazon MSK and Kinesis offer distinct advantages based on specific requirements. For an identical throughput using a perfectly sized MSK setup, Kinesis is notably more cost-effective. However, when considering factors such as leaving headroom in Kafka or dealing with significant capacity changes throughout the day, Kinesis proves to be a compelling choice due to its flexible cost allocation model.

Furthermore, Amazon MSK's ability to handle millions of messages per second makes it an ideal solution for high-throughput scenarios where scalability is paramount. The ease of scaling the Kafka cluster by adding or removing instances ensures that performance can be tailored according to real-time demands without compromising on latency.
