very wide OpenStack is a platform, not a concrete embodiment openstack uses driver architecture to support a variety of specific implementation technologies. For example, OpenStack storage service Cinder only defines the upper-level abstract API, the implementation of the following Driver, such as the LVM-based iSCSI DRIVER,EMC, IBM and other commercial storage products Driver, or open-source distributed storage software, such as Ceph, Gl

... Everything Even people like Cloudman, who work in this field every day, feel a lot of pressure. OpenStack is a platform, not a specific implementation scenarioThe various components of OpenStack use driver architecture to support a variety of specific implementation technologies. For example, OpenStack storage service Cinder only defines the upper-level abstract API, the implementation of the following Driver, such as the LVM-based iSCSI DRIVER,EMC, IBM and other commercial storage produc

engine to complete.VIII. Distributed Storage System/CDNFor access optimization of unstructured data, the general strategy is to build a distributed storage system. The supporting distributed storage System is a storage system with good expansibility and concurrency performance, and the well-designed distributed storage System can realize the fast location of access files, speed up reading and writing, and realize high concurrency. For example, Ceph i

Block Storage ServiceBlock Storage Servicet provides management of volume from creation to deletion throughout the life cycle.From the instance point of view, each of the mounted Volume is a hard disk.OpenStack provides a Block Storage Service that is Cinder, with the specific features: Provides the REST API to enable users to query and manage volume, volume snapshot, and volume type Provide scheduler dispatch volume create request, reasonably optimize the allocation of storage res

Libvirt driver.I wonder if you remember when we learned Glance: OpenStack supports multiple backend to store an image. It can be local file system, Cinder,ceph,swift and so on.In fact, this is also a driver architecture. The new storage method can easily be added to the backend support list as long as the Glance definition specification is met.We will also see the application of the driver framework in the back Cinder and Neutron.Messaging ServiceIn
