This is one of the most common themes in our environment today:
Is it scalable?
This is the number one question I hear when discussing new server products. It has become a common barb against many of the Microsoft products (including the Backoffice suite).
I do not agree with this notion, but I have seen it come up a lot.
Basically, scalability is determined by the ability to add to (or subtract from) an environment without having any adverse (mainly performance based) problems.
Here is a link to some whitepapers on scalability:
Here is a link to a freeware tool for testing scalability for Web servers:
Here are some questions that you can ask yourself to see if your network/software/infrastructure are scalable:
If I add 100 users to my network, will there be any impact? What about 1000 users?
In 6 months, at my current rate of expansion, will I need more servers?
If I add more administrators, can my server software handle all of them accessing it at the same time?
If I need to expand into a new office, can my network support a new routed subnet?
If people start to work from home, can I handle more RAS traffic?
Just some food for thought.
