Cloud services come in different forms. Collectively the term Cloud means any digital service that is delivered from a remotely hosted server or platform. This could be software applications or even server infrastructure itself.
Using software as a service (SaaS) is great for growing businesses. You get the flexibility to only pay for the number of logins you need each month and capital expenditure is minimised. Many cloud applications are entirely browser based which reduces the cost of deployment and the support headaches associated with more traditional models. Most cloud services are accessible from any Internet connection so remote access is built right in.
For companies who want to take advantage of the flexibility of SaaS but need more advanced configurations then Infrastructure as a Service (IaaS) may be the answer. By deploying whole servers or networks of servers in the cloud it is possible to create a custom infrastructure which meets your business requirements exactly.
