General purpose
An OpenStack general purpose cloud is often considered a
starting point for building a cloud deployment. They are designed
to balance the components and do not emphasize any particular aspect
of the overall computing environment.
Cloud design must give equal weight to the compute, network, and
storage components. General purpose clouds are
found in private, public, and hybrid environments, lending
themselves to many different use cases.
General purpose clouds are homogeneous deployments. They are
not suited to specialized environments or edge case situations.
Common uses of a general purpose cloud include:
Providing a simple database
A web application runtime environment
A shared application development platform
Lab test bed
Use cases that benefit from scale-out rather than scale-up approaches
are good candidates for general purpose cloud architecture.
A general purpose cloud is designed to have a range of potential
uses or functions; not specialized for specific use cases. General
purpose architecture is designed to address 80% of potential use
cases available. The infrastructure, in itself, is a specific use case,
enabling it to be used as a base model for the design process.
General purpose clouds are designed to be platforms that are suited
for general purpose applications.
General purpose clouds are limited to the most basic
components, but they can include additional resources such
as:
Virtual-machine disk image library
Raw block storage
File or object storage
Firewalls
Load balancers
IP addresses
Network overlays or virtual local area networks
(VLANs)
