OSIS Stub Project

Abstract

VMware Cloud Director Object Storage Extension (for short, OSE) is a standalone middleware service installed in private data center or public cloud to provide object storage capabilities to the users of VMware Cloud Director. OSE supports three object storage platforms out of box: Cloudian, Dell EMC ECS and Amazon S3.

OSIS (Object Storage Interoperability Service) is proposed to extend OSE to support other object storage platforms by defining unified administrative interfaces for storage platforms.

For the platforms integrated with OSE via OSIS, the data channel is between OSE and the platform, but the control channel is between OSE and OSIS implementation (REST services implementing OSIS).

This is a stub project for OSIS, which provides the skeleton for developer to start their work.

Usage

The project has stub and default implementation. Add or modify anything necessary to make it work for new storage platform support.

Module platform-admin-client is for platform administrative client.

Module osis-core has the project implementation.

  • package com.vmware.osis.model contains OSIS models
  • package com.vmware.osis.security contains default implementation of two authentication schema: Basic and API token
  • interface com.vmware.osis.service.OsisService provides the methods OSIS models manipulation, which should be implemented by com.vmware.osis.platform.service.impl.PlatformOsisService
  • any required beans can be declared in com.vmware.osis.platform.configuration.PlatformConfig
  • package com.vmware.osis.platform.security contains default implementation for platform specific user data
  • class com.vmware.osis.platform.utils.ModelConverter should provides the methods to convert OSIS and platform models
  • class com.vmware.osis.platform.AppEnv holds any application properties
  • class com.vmware.osis.resource.OsisCapsManager gives default implementation to collect the APIs annotated with @NotImplemented

Module osis-app has the REST interfaces of OSIS services class com.vmware.osis.resource.OsisController has default implementation of the OSIS REST controller
