Some time ago I wrote about the dangers of taking certain things for granted with new technologies.
This time I wanted to use a more specific enterprise application example to show that customers need to be extra careful when comparing solutions, especially for mission-critical apps.
Sometimes being too high-level means missing the unspeakable horrors lurking under the covers. And ignorance doesn’t mean bliss… just nasty surprises.
To summarize: Avoid bait-and-switch so you avoid surprise costs and pain.
- Ensure all components in any sizing tools reflect your business requirements.

- Ensure you are accounting for the right number of systems (Production-spec vs non, times number of applications, etc). This can quickly add up with certain apps.
