If synthetic transactions are dead as an approach for determining availability and performance from the perspective of the end users of an application then something has to take their place. The two candidates are approaches that analyse data on the IP network, and client side agents. Both will likely rise in prominence as more applications become more dynamic.
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.
For a developer, and subsequently the team of people that has to support certain kinds of applications in production, a PaaS cloud can be a wonderful thing. Why can a PaaS cloud be so wonderful? Because if you have a web based application based upon Java, Ruby-on-Rails, or .NET you can find a cloud provider that handles the entire hardware and software platform for your application.

2010 will be the year that many enterprises confront two very important changes to how they will use server virtualization. The first change is that as VMware vSphere has proven its maturity, performance and scalability enterprises will increasingly put business critical tier applications, at least in part on virtualized platforms. The second change is that at the same time, these very same enterprises will start to evaluate virtualization platforms from other vendors, in particular Hyper-V from Microsoft.

Since the major push on the part of VMware with vSphere is to virtualize Tier 1 applications, it is important to understand how the Application Performance Management solutions for virtualized Tier 1 applications is evolving in support of this trend
