Jim Frey, who I’m assuming is the Jim Frey who works at EMA rather than the Jim Frey who led the Kansas City Royals to their first American League Championship in 1980, has recently written an article in Network World about how network operators are, according to an EMA poll, most likely to be handed the responsibility for managing cloud services.
One problem is that it’s a lot harder to visualized managed environments, as well as knowing where the boundaries are that clearly denotes “this is our stuff” from “this is our cloud service provider’s stuff,” and “this is our WAN service provider’s stuff.”
Yet, concern over “poor service quality” – i.e., poor application performance – were not seen as a major issue in EMA’s poll, with only 18% of respondents indicating that they “had experienced or expected to experience poor service quality.”
Interesting. I think this may be because while the problems associated with cloud computing and managed services are indeed new, in many ways, they’re not that different from the problems of having internal applications accessed through the WAN.
Which makes the networking group, which has probably spent the last half-decade or more getting the applications to behave on the WAN, old hat at many of the problems that cloud computing posts – and, of course, any cloud computing solution, by definition, has to go through the network. If you’re talking about cloud services operated by a service provider such as Amazon or Microsoft, you’re talking about working on the WAN, with latency and bandwidth limitations.
As always, there was support for network monitoring – more than half of the respondents indicated that performance and availability were the most important service monitoring disciplines – and application response time was considered the second most important metric. (Fault reporting was considered the most important.)
One last thing - poor performance in the “physical,” non-virtualized world could often be solved by “brute-forcing” the problem. That is, you throw enough infrastructure at it until the problem “goes away.” But that way of “solving” problems not only won’t work in a budget-tight recession – it won’t work at all in the cloud because you don’t own all of the infrastructure. Ultimately, performance problems need to be handled by finding out where the bottleneck is and seeing what you can do to get resource usage under control, rather than just throwing more at the problem with diminishing returns.
