OpenStack introduces many challenging problems for storage administrators due to the need for scalable and reliable storage for very large scale unstructured data created by OpenStack applications. While many vendors have focused on the problems of VM Sprawl and the need for thousands of relatively small but high performance Cinder Volumes, very few have focused on the problems of storage for OpenStack applications that create and manage Petabytes of image, video and other large unstructured data objects. Today, a new generation of object storage systems provide the ability for applications in OpenStack environments to access storage over the fast growing AWS S3 interface. This provide advantages and a wide set of advanced storage features including Accounts for multi-tenancy, Buckets with Versioning, Replication and Lifecycle Management (S3). Furthermore,S3 provides an extensive security models for authentication, identity and access management and user policies and integration with Enterprise security services such as LDAP and Active Directory. This session will explore the use of the S3 API for storage in the OpenStack environment as the best of both worlds for deploying scalable cloud based applications.
