The third subsystem is hosted in a VM image in the FlexiScale Cloud infrastructure [Fle]. In an Ubuntu 10.04 64 bits operative system with a Java 6 VM we install the following components (see Figure 7.2): • JOnAS 5.2.2. • PostgreSQL 9.1.1. • Extended version of JBIMulti2 • A MySQL 5.1 database system which hosts the tenant 1 database. • Extended version of ServiceMix-mt: we modify its minimum and maximum heap consumption allowance, and set it to minimum 256 MB, and maximum 1 GB. • TPC-H data and query generator. • Resource measurements component The resource measurements component measures the CPU utilization of the ServiceMix-mt Java process. Its memory consumption is measured using the JConsole program provided by the JVM (Java Virtual Machine). In this evaluation we are interested in measuring the heap 82
7.3. Evaluation consumption, rather than the memory which is consumed by the JVM. The TPC-H is not used for measurement purposes, but only for data and query generation purposes. The evaluation scenarios are defined in Table 7.1. We define 8 different scenarios, which follow the following criteria: • Direct connection to the backend database system vs. connection through ServiceMixmt. • Number of Users, number of concurrent requests per user, and number of requests per user. • Data stored in a local MySQL database (in the same instance as ServiceMix-mt) vs. data stored in an Amazon RDS MySQL database instance. 1 select l_returnflag, l_linestatus,sum(l_quantity) as sum_qty,sum(l_extendedprice) as sum_base_price,sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,sum( l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,avg(l_quantity) as avg_qty,avg(l_extendedprice) as avg_price,avg(l_discount) as avg_disc,count(*) as count_order from lineitem where l_shipdate
