Stratus cloud classified as pannus clouds. Stratus only has one mutatus mother cloud. Stratus stratocumulomutatus clouds occur when stratocumulus opacus patches fuse to create a stratiform layer. Stratus clouds don't produce accessory clouds, but a supplementary feature praecipitatio is derived from Latin, which means "precipitation". Stratus clouds are too low to produce virga, or rain shears that evaporate before reaching the ground. A stratus cloud can form from stratocumulus spreading out under an inversion, indicating a continuation of prolonged cloudy weather with drizzle for several hours and then an improvement as it breaks into stratocumulus. Stratus clouds can persist for days in
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
