How to change Storage's replication option in Microsoft Azure

Last post I talked about saving money by using Locally Redundant replication instead of Geo redundant (which is the default) on Dynamics AX VM. Here's a follow up on where the setting is:

1) If you don't already know which "Storage" holds your VM's disk, check the disk name first by looking at the Virtual machine settings.

2) Then, you can confirm the Storage does hold that disk by going to a Storage, click Containers tab, then click the arrow besides a container name to check the contents.

3) Finally, go to the Configure tab and select a replication option.

Detail descriptions on all three options can be found here.
Locally Redundant Storage (LRS) replicate the data synchronously to 3 different storage within the same region. To me it's decent enough for non production environments. And, more importantly, LRS cost around 50% less than Geo redundant storage (GRS). Why not? =]

Small tips to save up on hosting AX2012 R3 Demo VM on Windows Azure

Now AX2012 R3 demo can be deployed fairly conveniently through Life Cycle service.
It is all good except that Azure isn't free. =)
When I deployed the AX2012 R3 VM I found that it is default to an A6 (4x 1.6GHz CPU, 28GB Ram)configuration VM using geo-redundant storage.
You should consider the A5 (2x 1.6GHz CPU, 14GB Ram) configuration, if that's good enough for your use then it's half the cost of an A6.
Also, even when the VM is turned off, a relatively small storage cost would be charged everyday. For a demo machine the geo-redundant is certainly an over-kill. Switching to local-redundant would save you around 50% compare to geo-redundant storage.
Finally, be reminded that compute charges still applies if you turned off the Guest OS inside the VM. You should either "Stop" a VM within the Windows Azure Management Portal, or through powershell to stop being charged on compute resources.
