Re: Hybrid Model Delivers Best Cloud
That NEC workload factoring model is fascinating! The underlying logic to route jobs based on data content and resource availability sounds complicated to set up, but it's just a matter of time before it's packaged into a wizard-driven application. Thanks for these links!

Re: Hybrid Model Delivers Best Cloud
Here's one example of that type of approach. In this example the architecture uses the cloud to handle transient load spikes segregated from the application platform's standard workload.

This article also has some interesting points relevant to the discussion.

Re: Hybrid Model Delivers Best Cloud
@Michael definitely not anytime soon.  It can still be a hastle just to switch vendors let alone utilize multiple vendors in one distributed hybrid cloud systems. You are right, until there are widely adopted standards it's not likely to materialize, and that is likely still years away.

Re: Hybrid Model Delivers Best Cloud
I'd like to hear more about the kind of segregation you're advocating, Roy. I understand the value from a securit and compliance perspective, but where are the segregated workloads running and how do they leverage cloud functionality?

Re: Hybrid Model Delivers Best Cloud
I think that's the holy grail of cloud computing, Chris, but I don't think we'll see it very soon. You can find gateways that will replicate across different cloud services, and even some providers that don't mind sharing, but the proprietary formats and lack of standards is going to make this supremely difficult in the near-term. 

Do you think we'll see real interoperability solutions hitting the market soon?

Re: Hybrid Model Delivers Best Cloud
Yes, someone pointed out to me the other day that a poorly-managed cloud can threaten to deteriorate into what he called "the bad old days of time-sharing." Of course that's the worst-case side of the story, not the whole picture of the topic under discussion. More positively, I think cloud data segregation can be useful for some applications such as workload delegation, security, and compliance. By the way I'm not suggesting either type of hybrid model is "better" than the other, I was just observing that I haven't seen equal discussion given to both models of hybrids, so I find this article opens up some new ideas.

Re: Hybrid Model Delivers Best Cloud
Developing a true hybrid cloud mixing public and private cloud resources is an interesting concept that sounds incredibly complex, but it's encouraging to see solutions like Eucalyptus to help us along.

Could we take things one step further, especially where burst computing is concerned and utilize cloud resources from multiple cloud vendors?  Companies could scale their cloud computing resources across multiple vendors depending on cost or other factors.

Re: Hybrid Model Delivers Best Cloud
I would think that when there are segregated roles, instead of integration between the clouds, why use different models at all? There would be less of a benefit. Also, if one cloud goes down and there is no integration within the enterprise, there would seem more of a chance of the entire business going down or having a long-term outag no? Unless there are segregated and separate clouds backing up the same data.

Re: Hybrid Model Delivers Best Cloud
That's a good observation, Roy, but if you're not sharing data, the ability to 'burst' compute jobs and shift workloads around dynamically is even more complicated, isn't it?

When things are kept segregated, do companies benefit less from cloud environments?

Re: Hybrid Model Delivers Best Cloud
"Companies, particularly large ones, are finding use for public and private cloud models, but the models are not interconnected, and resources are not shared." Interesting distinction Linthicum draws here between different concepts of "hybrid" clouds. I think I've seen more discussions of hybrids where data is segregated rather than shared. Seems like if you're sharing it, the challenge for optimization shifts to areas like bandwidth, syncing, and backup.
