Information Technology (IT) is changing rapidly. Power grids, traffic
control, healthcare, water supplies, food and energy, along with most of the
world’s financial transactions, now depend on information technology. Thus, it
forms an invisible layer that increasingly touches every aspect of our lives.
Some of the companies researching cloud computing are big names in the computer
industry. Microsoft, IBM, and Google are investing millions of dollars into research.
Cloud computing is an emerging IT delivery model that can significantly
reduce IT costs and complexities while improving workload optimization and
service delivery. Cloud computing is massively scalable, provides a superior
user experience, and is characterized by new, internet-driven economics.
Cloud computing could change the entire computer industry. The present
method of installing a suite of software for each computer can be replaced with
having to load only one application. That application would allow workers to
log into a Web-based service which hosts all the programs the user would need
for his or her job. Remote machines owned by another company would run
everything from e-mail to word processing to complex data analysis programs.
Cloud computing meets the high-performance demands of the dynamic Web by
using existing infrastructures to process massive amounts of information in
split seconds.
Gartner Vice President and Analyst David Cearley listed cloud computing
as number one on his top 10 strategic technologies for 2010.
One type of cloud computing, software as a service (SaaS), is the
hosting of one software application through the internet.
This approach, in which applications and data are maintained by the
provider, paid for on a subscription basis and accessed over the Internet, has
great appeal to companies and organizations that need new software services but
don’t have the budgets, expertise, technical staffs or time to manage it
internally. Thus software outsourcing can be better option.
However, SaaS and cloud computing is becoming a reality, security is
becoming more of a concern. Detailed in the SearchSecurity.com article, Cloud
Compliance: How to Manage SaaS Risks, are the significant security risks that
are imminent if the proper precautions are not taken.
Cloud computing is a fairly new and good alternative for a lot of
organizations, but the largest area of concern for companies is how to think
through the ramifications of outsourcing all software and sensitive data in
which it is stored across data centers operated by outside vendors, such as
financial enterprise, which require security and privacy.
