A B2B application has experienced performance issues that were
summarized as follows. FIRST, sensitive data exchanged over the
internet were not protected in transit (over the wire). The second
issue is about verifying client and server application identities
as they cannot not be verified within a B2B interaction. The third
issue is associated with the single database server, that is
subject to failure and requires repeated maintenance, which cannot
happen as they system need to be available 24 X 7.

situation, while explaining how each of the patterns will be
operating to solve these situations? (22.5 points each)
