If I go into the Azure Portal and provision a virtual machine there are a lot of steps that will happen in the background. The front-end will send API calls to the main fabric controller which will do a couple of things.
If it is part of any availability zone or proximity group, it will also honor those settings. This task is delegated via Microsoft. Compute resource provider. Storage resource provider to provision a managed disk according to size and performance layer needed. This also means provisioning replicas to provide redundancy defined. Then it can provide feedback to the front-end complete! Also, as part of this process, the different providers will also enforce QoS for the different building blocks to ensure consistency for others that also will deploy resources.
Within Azure there are multiple components to ensure high availability and scalability. Now you might argue, now why is Google Cloud a lot faster compared to Azure when provisioning resources?
The result however is that a VM is going to be placed on a hypervisor and the VM will only be shown as available and ready once the Azure VM agent is responding back to the fabric controller, but again the storage performance will also impact how quickly the VM will boot. There are a couple of distinct differences. Many do not take into consideration moving virtual infrastructure to a new platform which might be many miles away which will affect the performance of the VM regarding responding to a request from end-users.
In addition, depending on which direction the traffic goes there might be obstacles along the way which might start with your local ISP. This is also highly dependent on what kind of protocol is used for communication to the VM as well. Depending on what kind of VM size you are using this will also impact two things. For instance, bandwidth for a VM the sum of incoming and outgoing bandwidth, the same applies for bandwidth.
If traffic from your internal services is using Azure Firewall for outbound connectivity as well, there might also be that Azure Firewall is scaling which will impact traffic for 10 — 15 minutes each Firewall instance can handle between 1,5 — 3 GBps.
You also must consider which direction the traffic will flow; do you have force tunneling enabled to an on-premises gateway or do you have direct traffic from the public IP of the VM? Any tips, please help. Attachments: Up to 10 attachments including images can be used with a maximum of 3.

Storage optimized? Windows or Linux host? Additional information request. Post on pastebin. Add a comment. Active Oldest Votes. I would add logging, at least: When the request arrives to the server When a DB query begins When a DB query ends When the response is returned to the client This will give you an indication about where the problem is.
In addition - did you look at the machine's metric? Improve this answer. Sign up or log in Sign up using Google. It is an interesting idea which requires some additional thought. That said, the OpenStack clouds vary mostly by capabilities. The proprietary clouds are complete re-writes, but are generally relatively simple and well documented. However, that interesting accidental thing — as best as I can tell, Microsoft Azure is really really slow to launch instances.
