This provides the classes needed for Project 3. The main classes (Cloud, ServerLib, Database, ClientSim) and the sample database file (db1.txt) are in the lib directory. A sample server is provided in the sample directory. To build this, ensure your CLASSPATH has the lib and sample directory included. Then run make in the sample directory. To run the sample, try: https://cmu.zoom.us/j/92704500982?pwd=SlFNREhoanlYV3BsYUlRQ0JKc3dCUT09 This will launch the "Cloud" service, load the database with the items in lib/db1.txt, and start simulating clients arriving at a constant rate every 2000 ms. A single instance of the sample Server will be run as a "VM" (actually a spearate process). See the handout pdf for more details. See also the html documentation in the doc directory. In particular, read and understand the documentation of the ServerLib methods.
