Much has been written about ‘Cloud Computing’. Most would not disagree with the following definition:
“Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a metered service over a network (typically the Internet).” – Wikipedia.
Having chosen to adopt this model, the enterprise is still left with a choice: Whether to use public cloud services or develop a private cloud.
Northdoor offers cloud advisory services to help you define what place cloud services should have in your IT strategy and how to select the appropriate services and vendors thereafter.
We are experienced in designing, implementing and supporting applications and infrastructure in the conventional manner, a hybrid model and a pure cloud delivery model. We thus have an unbiased objective view and direct experience of how all these systems work together.
A public cloud service such as that offered by Northdoor is best suited to the organization with common utility computing requirements: File/Print, Microsoft office, Exchange Email, SharePoint and so on. The economy of scale allows us to deliver an efficient service based upon shared usage of the computing infrastructure with other clients. Delivery of all services is typically via an Internet connection, which together with whatever means of presentation is in use (phones, tablets, laptops, and desktops, etc.) represents the totality of the IT infrastructure that the user is required to manage.
What is a private cloud? Put simply, a private cloud is based around systems and services developed, deployed and provided by or on behalf of the Enterprise itself. The key benefits are:
An organisation will consider a private cloud when need for security is absolute and when bespoke or complex applications exceed the capability or facilities of the public cloud provider. Northdoor have built private cloud applications to meet these needs.

There are a great number of organisations who will consider the private cloud more than adequate for most operational needs, but also have a bespoke line of business application. The two options are not mutually exclusive and, with careful planning, can be combined to provide the complete service.
