The Top 3 Design Characteristics Of Mission Critical Systems

by tony1kenobi on July 7, 2008

In my experience I have found that there are three main design characteristics of large scale IT systems that are very important to maximise. These are:

High Availability

IT systems need to be highly available so that they are available when needed.

Scalability

IT systems need to scale as they grow so that increased load can be handled without interruptions to service and redesign of any hardware or software.

Performance

Visitors to a website, for example, do not want to wait more than a few seconds for the pages to load. So it is very important that the performacne of the system is good. Otherwise much potential business could be lost.
