Azure Virtual Machine – Frequently asked questions – not easily answered
Abs07act
Azure Virtual Machine is one of the core IaaS compute
offering of Azure world. It is very rich in features. I have hardly seen a
customer who is using Azure but not using a single Azure VM. Even if you decide
to be completely serverless, PaaS oriented; you end up using few Azure VMs for
sure in many cases.
Azure documentation has been improving a lot and link
here covers pretty good coverage on Azure VM FAQ - https://docs.microsoft.com/en-us/azure/virtual-machines/windows/faq
However I have seen many questions which are not answered
on official documentation and answer for such questions is available in bits
and pieces. Many times, we have to go through lot of documentation reading to
get answer for a simple question.
This blog post addresses very common question-answer on
Azure VM which are NOT covered in above FAQ.
I assume that you are working on Azure VMs already. This
FAQ is not suitable for people who don’t know Azure yet!
Lets go!
Before we go into the question and answer series it is
worth to show architecture of Single Azure VM.
As you can see above when you create Azure VM; you are
required to create all the services mentioned in above diagram. For the above
diagram I could derive below equation –
In Azure VM; we have compute and storage components
de-coupled from each other. Hence even if we shutdown (de-allocate) azure VM
and start again we get the same VM with same State and data again. Because all
data and state is maintained in storage part.
With this important understanding let us go ahead with
our actual questions and answers.
