SOA, virtualisation, Cloud, PaaS, IaaS – Service Models under pressure

By Tony Lock

In a nutshell:

The models used for businesses to create IT budgets have not changed significantly in a generation. The advent of new models for the production of applications and their operational deployment, especially virtualisation and SOA, are causing stress when budgets are fixed in a way that reflects static IT infrastructures, i.e. the application / server / storage silos that have heretofore been the mainstay of IT service delivery. Is it time for the way business pays for IT to change?

Key points:

• The use of new IT models, especially SOA and ’virtualisation’ are changing the way IT services are built and delivered.

• There exists great potential in the new models to offer flexible services that can be manipulated rapidly to meet changing business demands.

• Flexible IT utilisation requires IT budgets to have similar flexibility. Only with such changes can new systems deliver on the significant opportunities to reduce operational IT costs and increase resilience.
