Hybrid
cloud is a composition of two or more clouds (private, community or public)
that remain unique entities but are bound together, offering the benefits of
multiple deployment models.
Hybrid
Cloud are increasingly being used by corporations where there is a need to
maintain some of their applications on their internal infrastructure because of
regulatory compliance or due to sensitivity of data, but also need the
scalability and cost benefits of the public cloud.The most correct definition of the term “Hybrid Cloud” is probably the
use of physical hardware and virtualized cloud server instances together to
provide a single common service.But in most cases hybrid cloud is a
combination of private and public cloud.
By
utilizing "hybrid cloud" architecture, companies and individuals are
able to obtain services with fault tolerance combined with immediate usability
without depending on the internet connectivity.Cloud bursting is the term
normally used for this type of environment where internal applications are
deployed on private cloud for normal usage while internet applications are
deployed on the public cloud to handle variable loads.Hybrid cloud architecture
requires both on-premises resources and off-site (remote) server-based cloud
infrastructure.
Hybrid
cloud provides the flexibility and security of in house applications with the
fault tolerance and scalability of cloud based services.Two clouds that have been joined together are more correctly called as a
“combined cloud”
