Cloud Heroes
"The impact of performance fluctuation in IaaS has given users an incentive to modify their workloads to compensate for, mask, or otherwise avoid instability." Interesting. This feeds into a discussion we've been having this week about IT's hero complex. You may be going to great lengths to modify the app processing workload -- which really isn't creating economic efficiency for your company.

Biggest wild card
Smart geographic distribution of datacenters and caching schemes aside, what about the connectivity wild card? Unless a customer buys dedicated WAN bandwidth, what's Google's plan to smooth out the bumps of delivering service over the public Internet? And, is it watching the Net neutrality debate with some trepidation?

Netflix adopted work arounds to performance issues
Performance is the sleeper in evaluating cloud services. It's hard to compare pricing schemes, perhaps harder to compare performance. Netflix certainly did so and was surprised at the variations it found on Amazon EC2. It then figured out work arounds to avoid them. But not everyone is Netflix.

Re: Biggest wild card
Yes, you are right!  Locality is an important factor and the Net Neutrality discussion will play a key role here (as will the argument for on-premises implementations of popular IaaS systems/APIs).  What I am describing in this article is the performance variance within the datacenter.  If we can gain access to more stable systems inside the IaaS, it will be a big step in the right direction!

Re: Cloud Heroes
Great point -- and something we should all consider carefully: i.e., where we are putting our engineering effort in our on-going pursuit of "productivity gains".

You're still at the mercy of the Admins
Bless you Google for trying to solve one of the biggest issues with cloud stability, but the reality is that since you are still relying on the skillsets of the admin folks running the processes, it's really hard to control stability.  Throw in the many variables from connectivity to location, to server loads, not to mention the process types themselves, can we really assume that Google can control so much as to affect the stability of an entire environment?

IT's Reputation: What the Data Says
InformationWeek's IT Perception Survey seeks to quantify how IT thinks it's doing versus how the business really views IT's performance in delivering services - and, more important, powering innovation. Our results suggest IT leaders should worry less about whether they're getting enough resources and more about the relationships they have with business unit peers.
