All of the documentation for BES and BIS is openly available on the BlackBerry website here:

Hey man. Checked out that link and found exactly what I was lokin for but lost it! I searched through there and found a portion that explained and detailed BES & BIS and why it would be good to use and and the positives of using the technology and was exactly what I needed and cant find it now. Could someone look and see if they could find it!? Really need that for this paper!

BES all information is encypted by 3DES or AES.
BIS no data encyption.

BES uses PUSH. They are pushed by the BES server, they arrive to the BB at the same time they arrive to the email application.
BIS uses PULL. It has a delay of 5 to 20 minutes.

BES central IT administration.
BIS no.

BES if you book a meeting in the calendar it will be replicated to BB device at the same time using wireless network. The BB device doesn´t need to be connected to the computer.
BIS needs to be connected to the computer.
Idem for contacts.

BES when you send an email it will appear in the sent items folder immediately.
BIS no.

BES if you lost a BB device all the information will be available to be downloaded in a new BB device.
BIS, you will lost that information.

BES if you lost a BB device you can sent a command to earese all information.
BIS no.

Hope this information will help you.

take a look at these images they give you a good idea of the architecture on the issue:

BES well MDS apps but it shows the way data travels through. You get encryption, and wireless sync of your PIM data and redirection of subfolders to name a few features.


BIS much more simple in the way it works. the BIS server goes and pulls messages on a 15minute timer from POP/IMAP/OWA/Yahoo/Gmail type servers, and then push's them to the Blackberry.
