If true, does this sound like Amazon is violating the terms of use? I thought they guarantee to provide a certain level of service, such as CPU percentage, regardless of your neighbors.
I am not a virtualization wizard, but I always thought Xen and other hypervisors have CPU usage caps. If you're not getting built-in protection from noisy neighbors then VPS becomes just a crappier version of good old shared hosting. True? False?
P.S. I've been Slicehost user for 3+ years and all instances I've ever had there exhibited pretty much expected performance.
- wmf 17y agoI thought they guarantee to provide a certain level of service, such as CPU percentage, regardless of your neighbors. If they guarantee X performance but all along they were providing 2X and now they're only providing X, customers will complain. There are different ways to configure Xen so it's not clear exactly what Amazon is doing.

It can't be that difficult to say that within each 10-minute interval i you got X_i% of a CPU, received N_i packets, etc. This is the sort of data Amazon should collect themselves to analyze the systems within the cloud, so the customer never (OK, rarely) sees a problem.
