Cloud computing refers to the accessibility of computing resources like data storage. It
could be a good idea for the company to choose cloud computing but it can also effect the
company in a bad way because according to the National Institute of Standards and Technology,
"security and data privacy concerns are the two critical barriers to adopting cloud computing."
According to NIST, some of the common characteristics are: "homogeneity, virtualization, low
cost software, service orientation, advanced security, massive scale, resilient computing, and
geographic distribution," and some of the essential characteristics include: " broad network
access, rapid elasticity, resource pooling, measured service. Some of the benefits of cloud
computing would be flexibility, cost, scalability, and reduced technical burdens. It is flexible
because it allows for a quick access for additional computing power without the need for any
kind of backups, like purchase of a new hardware, software or services. For large companies it
can be difficult to store large amount data with the help of any other backup but it is possible that
these backups can have more cost and complexity than cloud computing. Cloud computing is
cost effective and provide companies with an overall low cost. Cloud computing is useful in a
way because it can provide with whatever resources a company needs, which in this case is the
problem of data storage. It also reduces technical burdens such as: electrical requirements,
hardware specifications, switch-port availability, software patching, and staff training. It
provides companies with the computing resources within hours, days and weeks. It enables
companies to only pay for the IT capacity they use and helps generate their revenue. Cloud
computing has an ability to reduce the exposure of private data from any external cloud. Lastly,
cloud computing very efficient because it can used from anywhere to everywhere, one doesn't
have to a laptop because it can be accessed simply from a mobile device. The cloud
infrastructure can be operated for a single company, could be shared by several companies, can
be made available to large group or it can be a composition of two or more clouds. Some of the
services that it provides are the accessibility to all of the applications from various devices and
the ability to process, store, networks and various other computing resources. While cloud
computing has some benefits, it has also some disadvantages that must be looked at before the
usage of it. The disadvantages include: cloud provider's security model determines the quality of
cloud security which can be disruptive for security investigations. The companies using this
provider have a hard time in responding to some hostile audit findings and companies can
experience the loss of physical control over their data and data processes. While keeping all of
this in mind, a company must know that cloud has been looked over as a risky business because
of the lack of control, regulatory compliance, and the annoying disasters such as hacks.
Therefore, it is obvious that cloud computing has more benefits than disadvantages but a
company must look over some of the issues related with it.
