Monitoring the performance of the infrastructure, applications and services in IT as a Service environments will require that monitoring solutions become multi-tenant, can be instantiated by ITaaS management tools without any further configuration, and that they automatically “find” their back end management systems through whatever firewalls may be in place. These requirements will probably be the straw that breaks the camel’s back for the heavyweight complex legacy tools that were in place prior to to the onset of virtualization, the public cloud and now IT as a Service. ITaaS is the tipping point that should cause most enterprises ignore every monitoring tool that they have bought in the past and to start over with a clean sheet of paper.
Cloud Performance Management needs to evolve and allow cloud vendors to provide their customers a customer specific Infrastructure Response Time metric. This in conjunction with cloud aware Applications Performance Management solutions is needed in order for customers to feel comfortable putting business critical applications in the cloud.
Infrastructure Performance Management is the single most important performance and capacity management issue that owners of a virtual environment need to address. The reason for this is that since the low hanging fruit has been virtualized, what is left is business critical and performance critical applications in the hands of applications owners and their business constituents. In order to convince these groups that the virtual infrastructure is performing acceptably in support of these important applications Operations groups in charge of virtual environments need to move beyond trying to infer infrastructure performance from resource utilization patterns.
Hosted Virtual Desktop (aka VDI) environments are sufficiently complex and different from either physical desktops or virtualized servers to warrant a dedicated approach to planning and assessing the migration from physical desktops to virtual desktops, and a dedicated approach to monitoring the resulting HDV environment in production.
