This paper describes the architecture and the implementation of
BlueStar, which uses a federation-based approach to design and
build Internet-scale data centers. Instead of aggregating all of the
compute, storage, and network resources in a single data center,
our approach uses the concept of a federation in which different-size
data centers participate to provide the capacity needed to
support Internet-scale applications. The main advantage of our
approach is that due to the inherent geographic distribution of the
data centers, applications can be easily provided with support for
high availability, disaster recovery, and localized access (reduced
latency). The approach also enables the service providers to realize
benefits by deciding to locate the hosting of applications to take
advantage of savings due to cost differentials between peak and off-peak
hours, power rates, and cooling costs across data centers.
Further, the approach enables individual data centers to maintain
independence and operational control over their resources. We
discuss the implementation of BlueStar using two sample composite
applications: BlueMaps, a server-side mashup application (i.e., an
application that provides data or functionality from more than one
location), and Lotus® Connections, a collaboration application.
