What is Cloud Computing?
Cloud computing simply refers to the delivery of IT as a service; so that storage and computational resources, software and information are shared and provided to computers and other devices in real time over the internet (or other network) using a subscription or pay-as-you-go pricing model.
What are the advantages of Cloud Computing?
Because cloud computing is delivered as a service, financing it is incurred as an ongoing operational cost. This means users of Cloud Computing avoid the upfront capital expenditure typically associated with IT deployment. It is therefore argued that cloud computing enables users to more rapidly deploy IT products and services without the risks and costs associated with a traditional IT deployment. Cloud computing is also usually perceived as far more easily scalable – enabling users to start small with new IT services and then scale them up rapidly once the concept is proven.
Why Compare the Cloud?
Cloud computing isn’t a single easily-defined solution. The term encompasses Software as a Service (SaaS) providers such as SalesForce, Google Docs, Dropbox and even Yahoo Mail as well as Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) providers such as Amazon Web Services (AWS), Google Compute Engine and many of Compare the Cloud’s own sponsors.
This represents a broad spectrum of IT utilities and there are many questions that need to be asked before embarking on any one solution – check out our Cloud Builder page to discover our top tips about the questions you should be asking.
Sounds great. So why isn’t everyone moving their computing to the Cloud?
Some businesses have been slow to accept and adopt cloud computing as an appropriate IT model. The most frequently cited reasons for not doing so are concerns about security and data management. Particularly in light of the Snowden revelations, businesses have been wary of the implications of cloud computing on data integrity, with many wondering whether regional providers offer greater protection than the large US cloud providers. However, the issue of data security isn’t limited to cloud computing; some analysts have suggested that initiatives to ‘right-source’ IT as a managed service overseas present far more potential risk.
So how do I find out if Cloud Computing is for me?
Like any IT solution, the key is to understand the requirements of your business and find a solution that best fits those requirements. Check out our Cloud Builder page for some ideas about the kind of questions you need to be asking about cloud computing.
