Seminar Outline
Planning for new eBusiness applications as well
as analyzing the performance of existing eBusiness applications brings unique
challenges over traditional methods. While the old rules still apply, they must
be modified to fit this new paradigm.
Understanding the anatomy and architecture of
web transactions, their resource consumption, and their resulting impact on
end-user response time is a necessary prerequisite to successfully analyzing and
predicting the performance of eBusiness systems. And because eBusiness
applications use a combination of software, hardware and network
architectures, performance evaluation and capacity planning for these systems
is non-trivial; it requires a solid understanding of those architectures, the
underlying workload, and the business service requirements that must be
achieved.
This seminar will provide you with an
understanding of web architectures, performance analysis for eBusiness
applications running on multiple platforms, the necessary analytic and
statistical modeling techniques, and how to build benchmarks and perform load
and stress tests.
