Today the media is filled with articles on cloud computing: Private clouds,
public clouds, hybrid clouds. Whichever option you chose - the overarching goal
is probably the same. Increasing capacity or adding capabilities on the fly
without investing in new infrastructure, training new personnel or licensing
new software.
The question sparking so much debate today is whether to use an internal cloud
or an external cloud, also known as private and public clouds. Regardless, internal
and external clouds provide easy, scalable access to computing resources and
IT services. And whether a cloud is public or private, the key to success is
creating a trustworthy and appropriate server, network and storage infrastructure
in which all resources can be efficiently utilized and shared.
Because all data resides on the storage systems in a shared infrastructure
model, data storage becomes even more crucial and there are many requirements
to consider before making the transition. Because the applications and services
are running in a cloud you need to make sure that data is available to those
applications in a timely fashion with the right storage provision. An effective
cloud storage strategy needs to be able to:
- Streamline and synchronize the storage environment with the target applications
and services they are running;
- Protect the applications, data and information assets within the data center
or outside of the data center;
- Improve utilization and virtualize the entire storage asset so it can be
offered as a single resource to the cloud.
What is Cloud Computing?
Not long ago, cloud computing was considered just another buzzword and everyone
had a different explanation for what it meant. With the maturity of virtualization
and the unprecedented economic pressure on IT organizations to do more with
less, cloud computing is proving to be the among the best options for your technology
infrastructure.
Cloud computing actually represents the convergence of many evolutionary developments
and trends in IT and in many ways is a realization of the last 20 years of architecture
development. According to Gartner Research, cloud computing emerged as three
major trends converged: service orientation, virtualization and standardization
of computing through the Internet.
