    If you want to host a dedicated Windows server on the cloud, and especially if you want to integrate it with your on premises Active Directory, Azure Virtual Machines should be your first choice. Obviously running Linux on Azure works very well too, but given Azure's pricing is not the cheapest, there are other providers out there that have a better cost-benefit ratio for Linux. That said, hosting Windows on Azure can be affordable (especially when compared to other providers) if you plan your licensing, topology, and application architecture correctly.

    KVM is the best solution in the case you need to test and turn up any virtual environment with limited vCPU/RAM resources. The obvious area of its use is a network environment when we want to avoid being tied to one type of hardware/vendor and being able to swap from one instance to another with no downtimes. The use of a vSwitch (that supports VLAN tagging) is a significant bonus for network engineers that some other hypervisors do not provide.

    Pros
    Microsoft
    • When demand is high, we scale the service out, eg During a Football Match.
    • When a football match is over and the throughput of data from OPTA drops we save by the service scaling back in.
    • Our App Service Plans along with the Clean C# code are lightening fast giving a good customer experience.
    • When producing the TV Guide information and a program overruns its scheduled time, a client can instantly be updated to the new programming schedule as our change is instant and its in the right place for all the clients to download and adjust their television guides appropriately to send out to the public giving a 24x7 uptime service that is precise and accurate and resilient to outages due to failover zones around the world.

    • KVM is really good at providing fast and reliable virtualization for Linux guests
    • Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
    • KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well

    Cons
    Microsoft
    • Pricing can be a concern if you are truly agnostic to which cloud you are building your particular solution in.
    • The UI, as is the case with any cloud provider, is crowded.
    • As with any cloud provider, it can be difficult to tune in exactly the right amount of servers for your needs...you might find yourself under/overprovisioning.

    • KVM itself doesn't ship with a management interface
    • KVM itself is a bit complicated to handle
    • KVM needs Qemu to virtualize Windows guests

    Usability
    Microsoft
    No VM console, weak management interface, changing CPU/memory is not straightforward. On the positive side, basic RDP functionality is good to have. As long as things are working, the ability to host Windows VMs is appreciated.

    It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

    I give the overall support for Azure Virtual Machines a 7 because I think while the overall support do a great job there are still areas that it could improve on such as efficiency and speed. So while I only give it a 7 and it has some issues it is still better than the overall support at Amazon EC2 Auto Scaling.

    Azure Virtual Machines offer unparalleled flexibility in provisioning, managing and upgrading the VM instances, both manually and programmatically. AVM offer very granular billing options and enables high costs optimisations (while still being costly). The other competitors I mentioned are very good at offering dead-cheap VMs. But if you need anything beyond that, especially for big computing, you need Azure Virtual Machines.

    It is a very reliable solution that can be used for x86 architecture virtualization with low overhead. It is a free and open source software. Easy to use withOpenStack.

    Return on Investment
    Microsoft
    • It's so easy to spin up new instances, that it becomes also to easy to have to many of them to manage. Many teams end up with a couple of hundreds of VMs after a short while, making the whole thing very hard to maneuver
    • Azure VMs are the next step for us to rely on Onprem servers, and leaving the management of the infrastructure to the professionals
    • The ease of use, is also important when our main focus is to deliver new applications and integrations fast, and not having to worry about infrastructure. We sell bottles, not CPUs

    • Fast provisioning of new servers.
    • Huge drop of the cost of servers compared to bare metal.
    • Easy upgrades of resources, sometimes now even requiring a server restart.
