An Accelerated Journey to the Clouds: An Analysis of TaaS Powered by xStream for SAP Applications

As obvious as it might at first sound, we need to remember that organizations building cloud environments face challenges in delivering application services. A key action is the need to define the application service end-to-end, ready for use, so that it consistently meets business needs. In practical terms this means character-izing workloads, specifying an optimized application environment, optimizing reliability and scalability, and automating workflows. Deploying on pre-validated server, storage, and network infrastructure will acceler- ate the process but it still needs a strong, validated testing process. As something of an answer here then, IT as a Service (ITaaS) is a cloud- based architecture where IT provides line-of-business with scalable, on-demand, secure IT services, either on premise or at third-parties.

Testing as a Service (TaaS) promises to provide IT with control and the LOBs with flexibility. TaaS will reduce some upfront CAPEX investments and issupposed to help to source requirements on an OPEX model. TaaS allows IT and the LOBs to include an on- demand, scalable, secure quality assurance process for their applications, accelerating testing and reducing the risk of moving applications to a cloud-based architecture.
