Subject: Why and How can a Company Use Cloud?
To Whom It May Concern
Cloud computing is an off-premise model of
computing that enables users to access IT resources at any time, from anywhere,
on an on-demand basis, through the Internet.
The main characteristics that cloud computing can
have are on-demand usage, ubiquitous access, multi-tenancy and resource pooling,
elasticity, measured usage and resiliency.
Actually P. Viswanathan listed the main advantages of cloud as cost
efficient, almost unlimited storage, reliable backup and recovery, automatic
software integration, easy access to information from anywhere with Internet
connection, and quick deployment. She also pointed out the main disadvantages of
cloud as possible outages of cloud services and connection, security concern in
terms of putting company’s sensitive information to third-party and being prone
to attack over Internet.
But anything has its pros and cons. As long as we
understand the possible threatens and then use cloud properly with technical
and non-technical measures, a cloud-based solution can prove to be a great
option.
Since cloud enable fast initiative and low
up-front cost, I could help with making prototype applications for testing
purpose from the very beginning. We could conducted a series of system testing
including parallel testing that runs the cloud application and existing ones at
the same time to if the cloud can replace the current IT application.
