Explanation/Reference:
* In the ITaas model, corporate IT offers a menu of SaaS, PaaS and IaaS options for business users via a centralized service catalog. Business users are free to pick and choose cloud services that corporate IT has vetted, or provide themselves. These users can make informed decisions based on service pricing and SLAs, and can in many cases can provision services on their own.
* ITaas can be implemented through new consumption models leveraging self-service catalogs offering both internal and external services; providing IT financial transparency for costs and pricing; offering consumerized IT – such as bring your own device (BYoD) – to meet the needs of users. All of which simplify and encourage consumption of services.
* A service-level agreement (SLA) is a part of a standardized service contract where a service is formally defined. Particular aspects of the service – scope, quality, responsibilities – are agreed between the service provider and the service user.
