Latest Update:  New Version of CDMI Submitted to ISO

November 2011

SNIA’s Cloud Storage Technical Work Group (TWG) has wrapped up work on a point release of CDMI (version 1.0.1) and has submitted it to ISO/IEC Joint Technical Committee 1 (JTC 1) under SNIA's new status as a Publicly Available Specification (PAS) submitter (granted in September).  This update release is a SNIA Architecture standard and includes bug fixes and minor improvements including standard IETF RFC 6208 Media Types. As the CDMI specification makes its way through the JTC 1 approval process, support from European National Bodies is needed in order for CDMI to become an international standard.

The Cloud Data Management Interface defines the functional interface that applications will use to create, retrieve, update and delete data elements from the Cloud. As part of this interface the client will be able to discover the capabilities of the cloud storage offering and use this interface to manage containers and the data that is placed in them. In addition, metadata can be set on containers and their contained data elements through this interface. This interface is also used by administrative and management applications to manage data (apply software data services), containers, accounts, security access and monitoring/billing information, even for storage that is accessible by other protocols. The capabilities of the underlying storage and data services are exposed so that clients can understand the offering.

The Cloud Storage TWG is also starting to scope work for a version 1.1 of CDMI that will include a number of extensions as they are implemented by multiple vendors.  For more information about this topic go to http://www.snia.org/cloud/newcontent.

Tutorial: Interoperable Cloud Storage with the CDMI Standard

The SNIA has published the CDMI Cloud Storage standard for implementation by cloud storage vendors as well as Public and Private clouds. This tutorial will overview the features of the new standard and explain how interoperability between clouds is achieved.

Learning Objectives
• How this cloud storage standard can achieve interoperability and what that means to you.
• How you can use the cloud storage standard both internally for private clouds as well as for public clouds.
• Who has implementation plans for CDMI and how will the implementations roll out.
