Cloud datacenters provide a backbone to our digital society. Inaccurate capacity procurement for cloud datacenters can lead to significant performance degradation, denser targets for failure, and unsustainable energy consumption. Although this activity is core to improving cloud infrastructure, relatively few comprehensive approaches and support to...

... explore the impact of better handling of physical machine failures, the impact of (smarter) scheduler allocation policies, and the impact of (the absence of) performance interference on overall performance. Figure 7 shows the impact of different operational phenomena on performance, for different allocation policies. We observe that performance interference has a strong impact on overcommission, dominating it compared to the Figure 8. ...
