ITMaaS vendors provide the essential management tools that enable users to access and view an IT environment, monitor and evaluate performance, and ultimately improve the functionality of IT environments through a cloud delivery model. The ability to gain visibility into an internal IT structure and deliver the performance data is a critical component within the management process. Through ITMaaS off erings, enterprises are able to easily capture, analyze and monitor the risks, costs, capacity constraints and other performance metrics that help ensure the optimization of IT resources. The ITMaaS segment is a part of the broader SaaS world. However, the adoption drivers and emerging market characteristics of the segment mimic those of IaaS and PaaS to a greater degree than the enterprise SaaS market.
