While creating an information system architecture to serve this new service, a
number of concerns must be addressed. Would cloud computing still be a good
idea if these issues were resolved? Why is this taking place, or why isn't it
taking place?

Expert Solution

Step 1

Information system architecture:

An architecture is a formal definition of the business processes and rules, systems structure, technical framework, and product technologies for a business or organizational information system.

Development steps of Information system architecture:

Information systems architecture development should consist of five steps, such as

Planning and Design Phase
Operational Analysis Phase
Requirements Analysis Phase
Function Analysis Phase
Physical Synthesis Phase.

The problems in information system development are low productivity, a large number of failures, and an inadequate alignment of ISs with business needs. The first problem, low productivity, has been recognized in the term “software crisis”, as indicated by the development backlog and maintenance problems.
IS development (ISD) efforts have resulted in a large number of outright failures . These failures are sometimes due to economical mismatches, such as budget and schedule overruns, but surprisingly often due to poor product quality and insufficient user satisfaction.
