Windows Azure IP ranges

It's not advisable to associate applications or policies to IP ranges since they can change anytime. Every time a you redeploy an application the you would get a different VIP. Also, as the Platform increases in size, additional IP ranges needs to be edited in the your firewall/proxy policy.
You can associate policies to the VIP of your deployment and VIP will not change as long as you only do production upgrades rather than redeployments.

Appfabric team blog provides IP ranges of AppFabric but they are also the same ranges as all Azure Platform Services and the Appfabric team updates it as and when new ranges are added.

Adding exception for *  to the firewall is also a good idea.
Various Ports used in Windows Azure Platform
80, 443
Default http, https ports used for various web scenarios
These ports are used by Windows Azure AppFabric service bus bindings
SQL Azure port
This port is used for RDP access to VM’s

This is a very useful blog for people looking for IP ranges for Microsoft Azure.

SQL Azure Error - 40544

If the size of your database reaches its MAXSIZE you will receive an error code 40544. You cannot insert or update data, or create new objects (such as tables, stored procedures, views, and functions).To fix this issue either increase your database size or delete data. For increasing/decreasing SQL Azure database size, you can use this command on the Master database. Alter DATABASE database_name MODIFY (MAXSIZE = {1|5|10|20|30… 150}GB); example: ALTER DATABASE sampleDB MODIFY (MAXSIZE = 5gb);

Hardware DEP (Data Execution Prevention), NX, XD & EVP

A processor can be instructed to designate regions of memory as non-executable. This means that the memory can be used to store reference data to be read and written, but that the processor cannot treat the contents of the memory as program code to be directly executed. Intel calls this capability in their newer processors XD for “eXecute Disable” and AMD refers to it as NX for “No eXecute.” AMD's marketing materials also sometimes refer to this capability by the term EVP for Enhanced Virus Protection.
As a hardware capability of modern processors this addition is important, but its use depends entirely upon support from the operating system. So when Microsoft introduced support for this into their operating systems, they termed it Hardware DEP for Data Execution Prevention. Support for hardware DEP was introduced into the 32-bit versions of Windows XP with Service Pack 2, into Windows 2003 Server with Service Pack 1, and has always been present in Windows Vista. Hardware DEP does …
