Everywhere you look you hear more and more about cloud computing as well as hearing one of my favorite lines from a Microsoft commercial “Let’s take it to the Cloud…”. Companies are jumping on the cloud bandwagon in quite a big way. I wanted to point out and mention some stories and services that I am using personally and having good success with.

Apple has done quite well serving up the AppStore and iTunes for the mobile devices and Apple has recently announced that it was discontinuing MobileMe and replacing the service with iCloud. It can go without saying that this has been an invaluable tool for use with my iPhone and iPad.

RUM (also called End User Experience Management) is becoming a critical feature of modern APM solutions. This is being driven by the emergence of rich client platforms like Ajax, Adobe Flash, Adobe Flex, and Microsoft Silverlight as well as the emergence of the iPad and Android based tablets as platforms for client side business applications.

Centralized RBAC Missing from Virtualization Management Tools

As a delegate for Tech Field Day 6 in Boston, I was introduced to several virtualization and performance management tools from vKernel, NetApp, Solarwinds, Embotics, and a company still in stealth mode. With all these tools and products I noticed that each were not integrated into the roles and permissions of the underlying hypervisor management servers such as VMware vCenter, Citrix XenConsole, or Microsoft System Center. This lack of integration implies that a user with one set of authorizations just needs to switch tools to gain a greater or even lesser set of authorizations. This is not a good security posture and in fact could devolve any security to non-existent.

In a world where you are changing everything – by moving applications in whole or in part from physical to virtual, to private cloud and ultimately (at least for some applications) to a public cloud, having an external reference point from which to judge the performance of these applications is essential. That reference point might best be the end user’s workstation, laptop or mobile device. Real User Monitoring solutions are likely to play a prominent role here.
