Stratus cloud a region. Some call these clouds "high fog" for the fog-like cloud. While light rain may fall, this cloud does not indicate much meteorological activity. Stratus clouds form when a sheet of warm, moist air lifts off the ground and depressurizes, following the lapse rate. This causes the relative humidity to increase due to the adiabatic cooling. Stratus clouds look like featureless gray to white sheets of cloud. They can be composed of water droplets, supercooled water droplets, or ice crystals depending upon the ambient temperature. Stratus nebulosus clouds appear as a featureless or nebulous veil or layer of stratus
Rackspace Cloud supported standard such as WebDAV. There are no concepts of "appending" or "locking" data within Cloud Files (which may affect some disk mirroring or backup solutions), nor support for permissions or transcoding. Data is organised into "containers" but it is not possible to create nested folders without a translation layer. Cloud Servers is a cloud infrastructure service that allows users to deploy "one to hundreds of cloud servers instantly" and create "advanced, high availability architectures" similar to the Amazon Elastic Compute Cloud. The "cloud servers" are virtual machines running on the Xen hypervisor for Linux-based instances, and Citrix XenServer for
