Amazon Keyspaces vs HPE Ezmeral Data Fabric

Amazon Keyspaces is a managed database service compatible with Apache Cassandra. It is serverless, requires no infrastructure management, and scales automatically with application demand. The service supports the Cassandra Query Language API, existing application code, Cassandra drivers, and developer tools. Tables can use on-demand read and write capacity or provisioned capacity with optional auto scaling. AWS describes single-digit-millisecond read and write performance, with no limit on table size or row count. Multi-Region deployments offer up to 99.999% availability, and table data is replicated three times across multiple Availability Zones. Keyspaces integrates with CloudWatch for performance metrics and can stream changes to Amazon OpenSearch Service. Keyspaces Streams provides change data capture, while point-in-time recovery can restore table data to any second in the preceding 35 days. Data is encrypted at rest by default, with AWS-owned or customer-managed keys. The free tier lasts for the first three months after creating the first resource, is limited to one per payer account, and includes 30 million write request units, 30 million read request units, and 1 GB of storage.

HPE Ezmeral Data Fabric consolidates data from on-premises systems, multiple clouds and edge deployments into one logical store. It supports files, object data, NoSQL databases and streams, with transaction support, strong consistency, multi-region support and horizontal scaling. Application developers can use standard APIs, languages and protocols. Its object store provides S3 API access, WORM compliance, events delivered to data streams and compatibility with open-source AWS S3 and Minio SDKs. Analytics integrations include Apache Spark, Apache Drill, Presto and S3 Select, while certified open-source tools and engines can run directly on the fabric for in-place analytics. Security capabilities include FIPS 140-2 Level 1 support when FIPS mode is enabled and dynamic masking of designated fields in JSON queries. A community edition is available, and an enterprise 30-day trial license can be requested. The community edition has limited nodes, no high availability or technical support, lacks advanced storage options such as snapshots and global replication, and is not intended for production. Pricing is on request; as-a-service monthly charges depend on storage use and selected tier.
