2. Virtualisation Drivers
Pervasive over-provisioning of servers
One application / one server approach in x86 environment
Computer resources are being wasted
IT Infrastructure lacks flexibility
Need for fast / ease deployment
Cooling and power requirements are increasing
Ageing hardware / operating systems
DR / BC
Test environment
5/27/2019

3. On its own virtualisation is not enough
We have been following our Business Plan from A to Z when implementing a virtual estate. We now have approximately 1000 VMs in a production environment and we haven’t saved a penny!

4. The Approach
5/27/2019

5. Discover – Servers, Applications & Services
Build an accurate and detailed inventory of an existing server infrastructure
5/27/2019

6. Server Details System Platform Software Performance Database Storage

7. Discover – Business Support Requirements
For each server, application and service determine:
Business process supported
Criticality of business process
Availability requirements
Response requirements
Disaster Recovery requirements

13. Design Design the strategic architecture and infrastructure components
Develop the centralisation, standardisation, consolidation and management plans for:
The infrastructure
The services, applications and data
Develop the project plan and resource schedules for each project
Develop the business case to support each project
