deployment
of mobile strategy, it can be assumed that data are set to grow by 15 to 20 percent every year.
As applications gradually move to the cloud, monitoring the applications is also set to become
a complex task due to dynamic provisioning and deprovisioning of IT resources to meet
applications’ demands. For example, an enterprise of 5,000 servers and 125 business applications typically generates 1.3 terabytes of IT operational data every day—via collection
of various metrics, such as events, server monitoring logs, application monitoring logs, endpoint
managers, network monitoring and storage monitoring. Enterprises need to adopt
analytical solutions that can analyze the terabytes of big data from IT operations and provide relevant
insights that can be acted upon immediately. Some of the situations where predictive maintenance may
apply are depicted in figure 2.
