List and describe the five requirement characteristics of infrastructure architecture.
1. Reliability: Accuracy of the system
2. Scalability: the ability of the system to meet the growth requirements of the organisation.
3. Flexibility: The systems capability of meeting the changing demands of the business
4. Availability: 99.999% of uptime, and ensures business continuity
5. Performance: how quickly a system performs a specific task
Describe the business value in deploying a service oriented architecture
An SOA is an IT architecture that supports integrating a business as linked repeatable tasks or services. An SOA ensures that an IT system can adapt quickly, easily to ensure the rapidly changing needs of the business are met.

What is a service?
A software like product that contains a set of commands that can be re-used over and over again.
What emerging technologies can companies can use to increase performance and utilise their infrastructure more effectively?
- Virtualisation: Increases the physical resources and maximises the investment of hardware by dividing a computer into multiple execution environments. E.g, Apple running windows.
- Grid Computing: Uses the processing software of computers that aren’t being used at certain times, so that large companies can use your computer when you are not.
