CAL VS CORE licensing SQL server

I need to purchase a SQL license for SQL server 2014 and i am not sure if CAL or CORE would be appropriate. the maximum users accessing the database thru web application would be no more than 100 users . does it mean that per 100 clients i need to purchase 100 CAL licenses?

any suggestion

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, every user must have CAL (direct or indirect user or device).

Advice: Install MS SQL Server on VM (Virtual Machine) with assigned 4 cores to VM and license 4 cores (min) on VM.
Physical host can have 16+ cores.

To scale you can add more cores to VM (and upgrade the license).

You can install any number of MS SQL Server instances on the same VM with the same one license for 4 cores.
