Chapter 3  Managing digital business infrastructure

Summary


Businesses need to provide a range a digital business infrastructure that can sup-

port users on a range of desktop and mobile platforms and is flexible enough to 

change with different business demands.



Mobile platform decisions involve selection of which mobile operating systems to 

target, provision of  mobile-  based services and whether additional apps are required.

A  five-  layer model for managing digital business infrastructure is reviewed where 

Level I is the applications layer, II is the systems software layer, III is the transport 

layer, IV is the storage or physical layer and V is the content or data layer.



Integrating different web services using Cloud Computing can enable business soft-

ware functions to be added with limited bespoke development.

Software as a Service (SaaS) providers are increasingly important as businesses 

look to reduce infrastructure costs and improve service delivery through external 

hosting of applications and data outside an organisation.
