You might see that we make a distinction between Software-as-a-Service and Cloud computing. So use this page to see our definitions on particular terms. We think you'll like the way we think.
Cloud computing - by our definition is about being able to utilise an I.T. infrastructure located on the Internet. When you need to scale your infrastructure rapidly, then cloud computing is for you. Identify your requirements, choose your service providers and establish your connections.
IaaS - Infrastructure-as-a-Service is the provision of processing power (CPU's), storage, security and other such services to enhance the capabilities of an existing infrastructure. This is the first building block layer in any IT system. Typically, this is a pay-as-you-go service, and is used by companies for adhoc projects of variable duration of hours, days, weeks or months.
PaaS - Platform-as-a-Service is the provision of a development platform to create custom applications, and incorporates a ready made multi-tenanted infrastructure and development environment upon which to build and integrate your custom applications. Applications can be built in approximately one-fifth the time and at half the cost of traditional software application development.
Software-as-a-Service - is application provision over the Internet. You choose your application, subscribe your number of users and off you go. No worries about scalability, security, resilience or reliability. Those aspects are all part of your service level agreement (SLA).
SLA's - by our definition Cloud computing and SaaS SLAs are different to traditional outsourcing. In the cloud, it's black and white. Anything outside of the standard is clearly defined in terms of function and price. If you want a service, switch it on, and almost instantly it's available. This is computing for the masses. It's designed to be highly functional from the outset.
Storage - Its the only real consideration you have, when running your business in the cloud. The great thing is, when you run out, you just purchase some more and off you go!
Transactions - when utilising some infrastructure services, transactions are charged on a volume basis. Think of it just like your utilities at home. The more you use the more you pay. Similarly, you only pay for what you use.
