Changing Drive Letter of an Azure Drive (aka X-drive)

2011-02-07T03:20:00.002+05:30

Sometimes it might be necessary that you want your Azure drive to be always mounted on a fixed drive letter. Consider a scenario of an Azure VM Role where you need to mount an azure drive for data persistance and your VM demands the same letter for you azure drive, e.q. you installed SQL Server on your VM Role and for mdf files you specified azure drive as path so as to make the data persist.

Mounting Azure Drive in Azure Virtual Machine (VM) Role

2011-02-07T03:17:00.000+05:30

Mounting an Azure Drive in Azure VM Role can be beneficial in many scenarios. As we all know that Azure VM Role is not persistent, so once you deploy a VM Role and it is restarted, all the data that was not the part of the base image is gone. As we already know from a previous post that in a VM Role data is not persistent between restarts or hardware-failures, we need to identify a way to

Data Persitence in Azure VM Role

2011-02-07T02:58:00.001+05:30

Azure VM Role involves creating a base image, uploading it to Azure using csupload, and then creating a servic model in Visual Studio to point to the uploaded base image. Once Azure VM Role is deployed, it creates a new drive with letter D: and name it Resources. A shortcut to this drive is added to your C: drive (Windows Drive). Once you restart the machine the data on drive D: would be

Unable to connect to Azure VM Role for a long time after it is Deployed or Restarted

2011-01-22T01:03:00.000+05:30

I have been really frustrated in waiting for days to log in to my VM Role instance via RDP. I have encountered this issue multiple times. Once a VM Role is deployed or it is restarted, we can not login via RDP for a long period, and it takes a lot of time, sometimes 2-3 (random) days once it is back and allows us to connect via RDP. Reason This issue occurs due to a problem with the Azure

Startup Tasks in Azure Virtual Machine (VM ) Role

What is Relying Party (RP)

2010-09-22T00:38:00.002+05:30

An application that accepts tokens from an STS is called as a Relying Party (or RP). In modern scenarios, web applications use WIF and accept tokens from an STS to manage authentications process. These tokens acts a proof that user has been authenticated by our application. Thus, our application relies on an external service i.e. an STS to provide Access Control and thus our application is

What are Claims

2010-09-22T00:35:00.002+05:30

A claim can be a user name, user’s email, it can even be permissions such as canWrite, canRead etc or it can be roles or groups to which the user belongs. When an STS generates a token, it embeds

What is Security Token Service (STS)
