Chris Fleck's Blog As described in part 1 of this blog series, the cloud is not the answer for every enterprise or every workload. This is true based on the current economics even without considering additional factors like security, control and SLA's. On the other hand the economics do point out a major cloud advantage when it comes to short term or variable workloads. (Pointed out by Michael Keen and Billy Marshall as well). Perhaps this is not very surprising to many, but it does help to look at the numbers to put it in perspective. The largest Intrinsic cost advantage of the Cloud is the ability to share infrastructure among multiple customers ( i.e. Multi-Tenancy and/or Multi-Instance ). This comes into play when many customers have variable workloads that are not likely to overlay at the same time. A Cloud infrastructure can load balance this workload on-demand... (more)

Cloud Computing Economics, Part One

Chris Fleck's Blog The economics of Cloud Computing do point out a major Cloud advantage when it comes to short term or variable workloads.

What is the Nirvana Mobile App?

With the release of Citrix Receiver for iPhone 1.02 including AG and RSA support, the ability to securely deliver any app, anywhere, is closer than ever to reality ( we already cover WinMo, Symbian and close to BlackBerry and Android ). One question I have been pondering with Martin Duursma and few others on the team is what is next ? It's great we can get to all these other Windows and RIA apps, but the app many of us use most is email. The question is, what is missing from native iPhone email or Outlook ? What features would be most useful for a mobile app that we would use al... (more)
