With advances in virtualization technology, virtual machine services offered by cloud utility
providers are becoming increasingly powerful, anchoring the ecosystem of cloud services …

Web applications are mostly designed with multiple tiers for flexibility and software
reusability. It is difficult to model the behavior of multi-tier Web applications due to the fact …

Elastic resource scaling lets cloud systems meet application service level objectives (SLOs)
with minimum resource provisioning costs. In this paper, we present CloudScale, a system …

We propose a new design for highly concurrent Internet services, which we call the staged
event-driven architecture (SEDA). SEDA is intended to support massive concurrency …

The memory coherence problem in designing and implementing a shared virtual memory on
loosely coupled multiprocessors is studied in depth. Two classes of algorithms, centralized …

Dynamically adjusting the number of virtual machines (VMs) assigned to a cloud application
to keep up with load changes and interference from other uses typically requires detailed …

This paper presents a feedback control real-time scheduling (FCS) framework for adaptive
real-time systems. An advantage of the FCS framework is its use of feedback control theory …

Elasticity-where systems acquire and release resources in response to dynamic workloads,
while paying only for what they need-is a driving property of cloud computing. At the core of …

This dissertation presents an automated system to generate highly efficient, platform-
adapted implementations of sparse matrix kernels. We show that conventional …

As Internet services become more popular and pervasive, a critical problem that arises is
managing the performance of services under extreme overload. This paper presents a set of …
