Abstract
|
Large scale e-commerce enterprises like Yahoo and Amazon use
complex software systems made of hundreds of Internet services
to serve content to millions of clients. These services are
multi-tiered Web applications that perform certain business logic
and are exposed through well-defined client interfaces usually
accessible over the network. A constant challenge faced by these
organizations is to host these services in a scalable fashion to
meet performance goals. A vast amount of research has been done
by the community on caching and replication solutions that aim
to improve performance of a service by addressing the
bottlenecks at its different tiers (e.g., database and
presentation tiers). However, different techniques are suited
for different kinds of services and it is not easy for an
administrator to choose the best set of techniques for a given
service. Our position in this paper is as follows: We believe
that the decision process of choosing the right techniques for a
service requires analysis of service and workload at each tier
and that to a large extent this process can be automated. To
strengthen our position, we propose the design of an autonomic
hosting system that uses a combination of multi queue models and
online simulations to achieve our goals. Even though our work is
very much in progress, we believe the techniques used in our
system can provide a good start in taming the complex problem of
scalable hosting of services.
