One nice thing about having more cloud providers is having more options for where your computation was housed. I have had a machine at Joyent for a long time now (with the goal of building a service that I never got around to, so sadly for them only ever the one computer) because their US South West datacenter is located not just "in Vegas" but specifically at the SwitchNAP SuperNAP site, which co-located me with other resources I was using: I had a <1ms ping to my upstream telecom provider, and thereby could sit inside of real-time audio without adding noticeable latency (as well as have the option of getting extra-cheap bandwidth: I wasn't going to be costing Joyent anything for bandwidth but was still intending to use lots of CPU, so they had indicated a willingness to let me one-off this billing if I ever actually scaled up, though I was still quite happy to pay the full price for the epic latency). AWS is great (and I honestly used them for most of my less latency sensitive projects... hence the problem for Joyent, I appreciate), but their lack of a South West location means that the lowest ping I can get from them for this purpose is almost 20ms :(.
