Oject Storage Extension Samples


VMware Cloud Director Object Storage Extension (OSE) is a midware which provides the capability of consuming object storage services for Cloud Director users.

Since version 2.0, OSE opens the extensibility framework for vendor and community to integrate third-party S3 compliant object storage platforms with Cloud Director. The extensibility framework offers a set of REST APIs for the vendor to implement upon the third-party object storage platform, called Object Storage Interoperability Services (OSIS). Below diagram gives the overview of OSE architecture and OSIS' position in the system.

Common Test Suites is developed based on boto3 to verify the compatibility of OSE certified storage platforms, like Clouian HyperStore and DELL ECS.
