|
Infrastructure Architecture - components |
Flexibility Scalability Reliability Availability Performance |
|
|
Flexibility |
systems must be flexible enough to meet all types of change |
|
|
Scalability |
refers to how well a system can adapt to increased demands |
|
|
Capacity Planning |
determines the future IT infrastructure requirements for new equipment and additional network capacity. - ensures the IT infrastructure is scalable |
|
|
Reliability |
ensures that all systems are functioning correctly and providing accurate information. Another term for accuracy |
|
|

|
|
|
Interoperability |
the capability of two or more computer systems to share data and resources, even though they are made by different manufacturers. |
|
|
Events |
The ears and eyes of the business expressed in technology. They detect threats and opportunities and alert those who can act on the information monitor information systems |
|
|
Services |
