Why Cloud Services

Why Cloud Services - A cloud service is any resource that is provided over the Internet. The most common cloud service resources are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Cloud services are the same thing as Web services. However, the term cloud services has been more commonly used as  cloud computing has become more pervasive.

Cloud Computing has been one of the hottest buzzwords over the last few years but surprisingly we have been using it for more than 10 years and whether you realize it or not, you are using it as well. Gmail, Facebook, Dropbox, Skype, PayPal, and Salesforce.com are all examples of cloud solutions. We just don’t think about them in these terms.

Numerous factors are driving cloud adoption, according to a study conducted by the market research company Vanson Bourne. “The Business Impact of the Cloud” report compiles insights from interviews of 460 senior decision-makers within the finance functions of various enterprises. The report summarized 11 drivers of cloud adoption along with quantifiable improvements these companies have achieved by deploying cloud services to improve productivity, lower cost, and improve time to market.

The main idea behind the cloud is that you can access all your information over the internet without having any detailed knowledge of the infrastructure used to enable it. Do you need to know about it? We don’t think so. Just like you don’t really need to know what the phone company or electric company does on their end to enable calls and allow the lights to go on when you flip the switch; and, you really don’t want to know as long as when you plug into it, it works.

Clouds can provide users with a number of different benefits. Many businesses large and small use cloud computing today either directly (e.g. Google or Amazon) or indirectly (e.g. Twitter) instead of traditional on-site alternatives. There are a number of reasons why cloud computing is so widely used among businesses today.

Reduction of costs, unlike on-site hosting the price of deploying applications in the cloud can be less due to lower hardware costs from more effective use of physical resources.

Universal access, cloud computing can allow remotely located employees to access applications and work via the internet.

Up to date software, a cloud provider will also be able to upgrade software keeping in mind feedback from previous software releases.

Choice of applications, This allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a business to use, access and pay only for what they use, with a fast implementation time

Potential to be greener and more economical, the average amount of energy needed for a computational action carried out in the cloud is far less than the average amount for an on-site deployment. This is because different organisations can share the same physical resources securely, leading to more efficient use of the shared resources.

Flexibility, cloud computing allows users to switch applications easily and rapidly, using the one that suits their needs best. However, migrating data between applications can be an issue.

Despite these benefits, the Cloud Security Alliance has identified several barriers holding back cloud adoption. At 73% of companies, the security of data is the top concern holding back cloud projects. That’s followed by concern about regulatory compliance (38%), loss of control over IT services (38%), and knowledge and experience of both IT and business managers (34%). As organizations address their security and compliance concerns by extending corporate policies to data in the cloud and invest in closing the cloud skills gap, they can more fully take advantage of the benefits of cloud services.
