An advice for the companies who are planning to shift to cloud: Start looking out for potential small applications which can benefit your organization being in cloud. Ideally, applications where resources are used for a shorter period and then left idle for the rest of the time, or applications where a moderate level of resources are used continuously with high activity period are the good candidates for cloud.

Why Cloud Computing and Why Not?
In this article we are going to focus on pros and cons of cloud computing and
when a business should go for cloud computing. Today’s enterprise world is
global; it involves direct & open communication with customers; transparency,
work mobility and collaboration are imminent. Let us see how cloud computing
can meet these demands of enterprise world.
 Cloud computing is OS and Application architecture independent. As
infrastructure is based on cluster of shared resources, you can run your
application from browser without worrying about underlying OS or App
architecture.
 REST based Application Programming Interface (API) accessibility enables
easy interaction with cloud software.
 Best platform for collaboration, social networking, SaaS, online presence
and enterprise integration.
 As application is on the cloud, applications and data can be accessed from
anywhere at any time through web browser.
 All hardware and network infrastructure is maintained by provider, it brings
hardware costs down. It also removes need of physical space for hardware
on premise.
 It helps converting IT Capex to Opex because you are no longer required to
invest in building huge data centers, do capacity planning, disaster
planning, cooling management etc. You just have to pay for resources you
use.
 As all application data is stored at central location on cloud, it gives
company-wide access to computer applications. It eliminates the need of
buying individual software licenses or installing any software.
 With cloud computing system, you save money on IT support. As there is a
tough competition amongst cloud service provider for gaining client
confidence, they provide on-demand availability, flexibility, and scalability
24x7x365.

 Easy performance monitoring and measurable resource usage on
daily/weekly/monthly/yearly basis.
 As we know, there is a huge server pool in backend of cloud system; you
can utilize the processing power of all available computers thus significantly
speeding up the calculation and response time.
 Cloud system is scalable on demand meaning you can add/remove server
any time within minutes. It is also flexible wherein you can
increase/decrease computing power and storage depending on your
business demand.
 You can expect your applications and websites in cloud to be always up and
available. Reason behind is that your data is refactored across multiple
servers so if one server fails, backup is always there.
Given that there are many advantages of using cloud computing technology,
there are some concern areas as well.
 Main concern for business is data security and privacy. If you tell your
business owner to handle over important data to another company, he
would not be convinced.
 Cloud computing is relatively new and emerging technology. There are only
few major players who are capable of handling this. But at the other side,
service providers are dying to attract customers by providing advanced
techniques and reliable security measures.
 Many cloud computing service providers have suffered outages/downtime
which are out of control for affected IT and business managers.
 Difficulty for providers in auditing complex security measures as data is
distributed across devices.
 To take full advantage of cloud computing, do I have to migrate all or create
new apps on the cloud?

 This question will definitely come in your mind; does the user or company
subscribing to the cloud computing service has control over data? Yes, you
will have control over your data but best solution is to have combination of
on-premise and off-premise to gain full control.
 Does company which provides cloud computing services actually owns
data?
So when a business should choose Cloud Computing as their technology swing?
 When the processes, applications, and data are loosely coupled or
independent.
 When the integration points are clearly defined.
 When a reduced security level will work fine.
 When the core internal enterprise architecture is powerful.
 When web platform is the only option.
 When cost is one of the major issues.
Looking at above pros and cons, we can understand that cloud computing is not a
solution to all problems but it simplifies our lives.
An advice for the companies who are planning to shift to cloud: Start looking out
for potential small applications which can benefit your organization being in
cloud. Ideally, applications where resources are used for a shorter period and
then left idle for the rest of the time, or applications where a moderate level of
resources are used continuously with high activity period are the good candidates
for cloud.
