22. Bottom Line, Which do I Need?
There isn’t a single answer!
Don’t try to place yourself in a ?aaS slot
Think what your are doing now on-premises
Bottom line, it really depends on:
What you need to accomplish
What your Dev & IT team knows to do
How customers prefer to consume your software
All four let you build scalable, reliable applications in the cloud.
Which you use depends on what you’re trying to do.
