Infrastructure

What is the Infrastructure?

- A conceptual level how the IT infrastructure supports an effective HER.

- Includes:supporting h/w, s/w and management systems required to run a particular apps or suite of apps

- Includes: data network, workstations, servers and telecommunications equipment and services

- IN most case, it also included the controlled environment in which many of these components operate.

- Backup and recovery plan

Network:

- use TCP/IP over LAN

- Network must be sized properly

Backup and recovery: how much security is enough>

No matter how carefully a system is design,tested and implemented, there will be tims when the system is unavavilble, either by plan or by accident

Planning for downtime is an important part of the overall implementation of any IT system but is particularly important when implementing an HER

- develop and test policies, procedures and technologies that will let u continue to function when the HER is unavailable.

- Amount of time, effort and money you decide to invest should be proportional to your level of risk, and the time, effort and money you llose when the sys is unavavilable.
