CSCI 360 Class Activity 5
System Design
1. Consider a system that includes a Web server and two database servers. Both
database servers are identical: the first acts as a main server, and the second acts as
a redundant back-up in case the first one fails. Users use Web browsers to access
data through the Web server. They also have the option of using a proprietary
client that accesses the databases directly. Draw a UML deployment diagram
representing the hardware/soft- ware mapping of this system. 2. You are designing a caching subsystem that temporarily stores data retrieved over the
network (e.g., web pages) into a faster access storage (e.g., the hard disk). Due to a
change in requirements, you define an additional service in your subsystem for
configuring cache parameters (e.g., the maximum amount of hard disk the cache can use).
