2.13. Apache JMeter
consists in selecting the Cloud provider which best fits the user’s operational and economical
interests, and in detecting incompatibilities with the selected target data store. The different
steps of the migration process are shown in Figure 2.8.
Figure 2.8.: Cloud Data Migration Process [Bac12]
In the data layer pattern selection and adapt data access layer steps, the user must specify how
to connect to the data store his data is migrated to, and provide the necessary information
to establish the connection. The extension of ServiceMix-mt for enabling Cloud data access
support allows the user to select this prototype for transparently access the migrated data.
2.13. Apache JMeter
Apache JMeter is a Java-based application which provides support for load testing and
performance measurement [Theb]. It provides support for different communication protocols,
e.g. HTTP, SOAP, database via JDBC, etc. A multi-protocol support enables the application
to be used for testing different layers of an application, e.g. presentation layer, and database
layer. Furthermore, the user can configure in JMeter different load parameters, e.g. number
of threads, iterations, etc., in order to build a heavy load simulation to run on the backend
server. Simulation results are presented in structured formats for posterior analysis.
In this diploma thesis we provide an evaluation of the behavior of the final prototype. Due to
the JDBC functionality supported by JMeter, we use it to generate the load test cases which
are run on ServiceMix-mt.
