Software as a Service
On-demand application delivery.
Software as a Service is a part of cloud computing, that is to say licensing and distribution of a specific software the customer accesses via Internet. It is licensed on a subscription basis and hosted centrally by an external provider.
Within the realm of Network Management and Services Assurance these are the main two options that customers are offered as to how they can purchase and consume solutions: the traditional on-premise (legacy) systems and the Software as a Service (SaaS) option.
Tremendous advantage and operational savings
- All hardware and software is delivered as a service via network
- Users are provided access to application software and databases, but do not own the underlying applications or technology
- The provider manages the infrastructure and platforms on which the applications run
- By outsourcing hardware and software maintenance and support to the cloud provider, the IT operational costs can be significantly reduced
- Management can focus on meeting more important IT goals due to reallocating IT operational costs away from hardware and software spending and personnel expenses
- Updates can be released without the need for users to install new software, since the applications are hosted centrally
By using a the Software as a Service model, the end-users get all of the benefits of the applications they need without all of the up-front cost, or ongoing complexity of maintaining that solution. The very rapid acceptance of this model has proven that this approach works and is a valuable to the IT and business community.
