Query: Robust Dynamic CPU Resource Provisioning in Virtualized Servers   We present robust dynamic resource allocation mechanisms to allocate
application resources meeting Service Level Objectives (SLOs) agreed between
cloud providers and customers. In fact, two filter-based robust controllers,
i.e. H-infinity filter and Maximum Correntropy Criterion Kalman filter
(MCC-KF), are proposed. The controllers are self-adaptive, with process noise
variances and covariances calculated using previous measurements within a time
window. In the allocation process, a bounded client mean response time (mRT) is
maintained. Both controllers are deployed and evaluated on an experimental
testbed hosting the RUBiS (Rice University Bidding System) auction benchmark
web site. The proposed controllers offer improved performance under abrupt
workload changes, shown via rigorous comparison with current state-of-the-art.
On our experimental setup, the Single-Input-Single-Output (SISO) controllers
can operate on the same server where the resource allocation is performed;
while Multi-Input-Multi-Output (MIMO) controllers are on a separate server
where all the data are collected for decision making. SISO controllers take
decisions not dependent to other system states (servers), albeit MIMO
controllers are characterized by increased communication overhead and potential
delays. While SISO controllers offer improved performance over MIMO ones, the
latter enable a more informed decision making framework for resource allocation
problem of multi-tier applications.
