What is Hybrid Cloud Computing?
Cloud computing has evolved in recent years. The new world
of the hybrid cloud is an environment that employs both private and public
cloud services. Companies are realizing that they need many different types of
cloud services in order to meet a variety of customer needs.
The growing importance of hybrid cloud environments is
transforming the entire computing industry as well as the way businesses are
able to leverage technology to innovate. Economics and speed are the two
greatest issues driving this market change.
There are two primary deployment models of clouds: public
and private. Most organizations will use a combination of private computing
resources (data centers and private clouds) and public services, where some of
the services existing in these environments touch each other — this is the
hybrid cloud environment.
The public cloud
The public cloud is a set of hardware, networking, storage,
services, applications, and interfaces owned and operated by a third party for
use by other companies or individuals. These commercial providers create a
highly scalable data center that hides the details of the underlying
infrastructure from the consumer.
Public clouds are viable because they typically manage
relatively repetitive or straightforward workloads. For example, electronic
mail is a very simple application. Therefore, a cloud provider can optimize the
environment so that it is best suited to support a large number of customers,
even if they save many messages.
Public cloud providers offering storage or computing
services optimize their computing hardware and software to support these
specific types of workloads. In contrast, the typical data center supports so
many different applications and so many different workloads that it cannot be
optimized easily.
The private cloud
A private cloud is a set of hardware, networking, storage,
services, applications, and interfaces owned and operated by an organization
for the use of its employees, partners, and customers. A private cloud can be
created and managed by a third party for the exclusive use of one enterprise.
The private cloud is a highly controlled environment not
open for public consumption. Thus, a private cloud sits behind a firewall. The
private cloud is highly automated with a focus on governance, security, and
compliance.
Automation replaces more manual processes of managing IT
services to support customers. In this way, business rules and processes can be
implemented inside software so that the environment becomes more predictable
and manageable.
The hybrid cloud
A hybrid cloud is a combination of a private cloud combined
with the use of public cloud services where one or several touch points exist
between the environments. The goal is to combine services and data from a
variety of cloud models to create a unified, automated, and well-managed
computing environment.
Combining public services with private clouds and the data
center as a hybrid is the new definition of corporate computing. Not all
companies that use some public and some private cloud services have a hybrid
cloud. Rather, a hybrid cloud is an environment where the private and public
services are used together to create value.
A cloud is hybrid
If a company uses a public development platform that sends
data to a private cloud or a data center–based application.
When a company leverages a number of SaaS (Software as a
Service) applications and moves data between private or data center resources.
A cloud is not hybrid
If a few developers in a company use a public cloud service
to prototype a new application that is completely disconnected from the private
cloud or the data center.
If a company is using a SaaS application for a project but
there is no movement of data from that application into the company’s data
center.
