In their own words
Amazon S3
Amazon S3 is an object storage service for storing, managing, analyzing, and protecting data used by data lakes, cloud-native applications, and mobile apps. Capacity adjusts as objects are added or removed, without requiring storage to be provisioned in advance. Storage classes cover frequent access, infrequent access, and archiving. Versioning preserves object versions, while Replication can copy objects to buckets in the same or different AWS Regions. Amazon Athena and Redshift Spectrum can query S3 data in place with SQL; S3 Vectors adds vector storage and querying, including integration with Amazon Bedrock Knowledge Bases. Security controls include encryption for uploads, Block Public Access, and Object Lock for customer-defined retention periods. AWS documents access through its Management Console, CLI, SDKs, and REST API. S3 is listed for Android, API, iOS, Linux, macOS, web, and Windows. A Free Tier is available. Pricing is usage-based, with charges varying across storage, requests, retrieval, transfer, and other features. Some archived objects have minimum storage durations of 90 or 180 days, and early deletion incurs a prorated charge.
OpenEBS
OpenEBS is open-source Kubernetes storage software for developers and platform SREs deploying stateful workloads. It turns storage on Kubernetes worker nodes into local or distributed persistent volumes and operates in userspace rather than relying on Linux kernel-dependent software. Its engines include Replicated PV Mayastor and local volumes using Hostpath, LVM, ZFS, or experimental Rawfile. Mayastor can synchronously replicate volumes across Kubernetes zones. Kubernetes-native operations provide copy-on-write snapshots and clones, while Velero plugins support backup and restore to AWS S3, GCP Object Storage, or MinIO. Volumes expose metrics including IOPS, throughput, latency, and traffic patterns for Prometheus and Grafana. OpenEBS also exposes declarative APIs through Kubernetes custom resources and can be installed with Helm 3.2 or newer. Mayastor disk pools support data-at-rest encryption with user-defined AES-XTS keys. Listed use cases include self-managed databases, observability stacks, CI/CD, object storage, websites, and ML pipelines. Mayastor DiskPools are limited to one block device, and encryption keys cannot be rotated.
