List of cloud types
The list of cloud types groups the tropospheric types as "high" (cirrus, cirrocumulus, cirrostratus), "middle" (altocumulus, altostratus), "multi-level" (nimbostratus, cumulus, cumulonimbus), and "low" (stratocumulus, stratus) according to the altitude level or levels at which each cloud is normally found. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Of the multi-level genus-types, those with the greatest convective activity are often grouped separately as "towering vertical". The genus types all have Latin names.
HP Cloud
There can be different types of hybrid clouds for specific tasks. The Infrastructure as a Service (IaaS) model can be a hybrid cloud in that it could use operating systems and virtualization technologies from both a public and private cloud infrastructure to provide cloud services. Other models that mix on-premises cloud with public cloud technologies include Platform as a Service (PaaS), which includes infrastructure services combined with development tools and middleware; and Software as a Service (SaaS), which is used to develop packaged software.
