More
Critical business requirements for IT service and web
Users - Business customers, end-users and clients
Services - Business customers’ view of applications
Architectures - abstraction, virtualization, consolidation
Tiers & pools, Web GUI, message handler, app server…
Applications, developments in-house, off-shore, packages…
Servers, machines, nodes, CPUs, RAM, networks, storage
Less
Overhead – IT infrastructure and services
Finance – budgets cut
Sites – consolidated data-centres
Staff – cutbacks
Spare capacity – headroom, duplex, DR, non-stop
Physical servers – virtualised and consolidated
Expertise – less experience and less training
