Comments:

1 (Daytrader)

• Daytrader has two pre-generated database sizes: 400 MB, by setting the attribute "TRADEDB_SIZE = small" and 6 GB, by setting the attribute "TRADEDB_SIZE = large".
• When using the "large" database, the number of users and quotes on the database can be increase by changing the attributes "NR_QUOTES=6000000" (default is 40000) and "NR_USERS=3000000" (default is 15000)
• The database can be placed on a ramdisk inside the DB2 VM, by setting the attribute "DB2_ON_RAMDISK = $True"
• Daytrader can be used in "scale-out" mode, by having a load balancer in front of multiple WAS VMs. To do so, changing the attribute "LOAD_BALANCER = $True". The number of WAS VMs can the be controlled by changing the attribute "SUT=client_daytrader->3_x_was->db2

2 (Tradelite)

• Contrary to DayTrader, the database is rebuilt each time a new load level is selected, using the default configurations on application.
• Usually Tradelite uses a Derby database, running co-located within the WAS VM. A 3rd tier, containing an actual DB2 database running on a separate VM can be added by setting the attribute "SUT=client_tradelite->was->db2"

Comments:

1. Requires preparation of the environment (Hosts with KVM) before it can be used. VM images will have to be manually copied to each Host before starting.
2. None.
3. OpenStack Folsom only.
4. The deployed daemon is part of CBTOOL's code, and works as an "endpoint" for the requests sent by CBTOOL. The deployment means that during cloud attachment, CBTOOL will ssh into the VM "webservice" (part of a normal SCP installation) and copy (and execute) the Ruby daemon originally located on (~/cbtool/scripts/common/scp2_python_proxy.rb).
5. Simulated cloud just creates concrete objects (e.g., Hosts and VMs) and abstract objects (e.g., Virtual Applications) on the Object Store only. Since the each operation takes only 1 second, it is a good way to test your experiment plan before running it on an actual cloud. In addition to that, this "cloud" is heavily used for debugging/development.
