Service isolation, achieved by deploying components of multi-tier applications using separate Virtual Machines (VMs), is a common \"Best\" practice. Various advantages cited include simpler deployment architectures, easier resource scalability for supporting dynamic application throughput requirements, and support for component-level fault tolerance. This paper presents results from an empirical study which investigates the performance implications of component placement for deployments of multi-tier applications to Infrastructure-as-a-Service (IaaS) clouds. Relationships between performance and resource utilization (CPU, disk, network) are investigated to better understand the implications which result from how applications are deployed.
