Amazon Managed Streaming for Apache Kafka (MSK) now offers Tiered storage that brings a virtually unlimited and low-cost storage tier. Tiered Storage lets you store and process data using the same Kafka APIs and clients , while saving your storage costs by 50% or more over existing MSK storage options . Tiered Storage makes it easy and cost-effective when you need a longer safety buffer to handle unexpected processing delays or build new stream processing applications. You can now scale your compute and storage independently, simplifying operations.
