PHYSICAL ARCHITECTURE LAYER DESIGN

An important component of the design of an information system is the design of the physical architecture layer, which describes the system's hardware, software, and network environment. The physical architecture layer design flows primarily from the nonfunctional requirements, such as operational, performance, security, cultural, and political requirements. The deliverable from the physical architecture layer design includes the architecture and the hardware and software specification.

OBJECTIVES

• Understand the different physical architecture components
• Understand server-based, client-based, and client–server physical architectures
• Be familiar with cloud computing and Green IT
• Be able to create a network model using a deployment diagram
• Be familiar with how to create a hardware and software specification
• Understand how operational, performance, security, cultural, and political requirements affect the design of the physical architecture layer
