Azure Virtual Machines vs. Kernel-based Virtual Machine (KVM)

It's well suited to delivering information about our sports events as during the events a lot of processing power is needed and instantly becomes available by scaling out when the event is over the service can be scaled right back making massive savings. We use it for football, horse racing, Olympics games etc, it is also used when things happen in the world like right now there is a lot of concern over the Russia and Ukraine conflict, since the demand for this information is high we instantly scale to meet the demand of our news feed services. I believe up to 90% of the UK's News, sports and media information actually passes through our computer systems, we are a market leading news and information service and Azure Virtual Machines provide us with the reliability that we need so that we can provide a rock solid reliable news and information service to the world.

Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).

• You can login to Azure VMs using SSO with your Azure Ad account
• Azure VMs are securely accessible from anywhere in the world, with Azure Bastion
• You can execute scripts on the VM from the Azure portal without logging in to it

• Lightweight built-in implementation for all *nix based OS.
• Easy to deploy and manage VMs.
• Freeware (is you are using a free OS).

• 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

They are very easy and intuitive, very easy to deploy

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.

Oracle Cloud Infrastructure's Compute supports Windows, but is really geared towards Linux. You can install Windows on some Linode servers, but again, Linode is geared towards Linux. AWS does everything but is complex and can have high costs. If you want to host Windows servers in the cloud, nothing beats Azure. From licensing to management, Microsoft Azure provides the easiest way to deploy and manage Windows Servers in the cloud, especially if you utilize other Microsoft services like Microsoft 365 an Visual Studio subscriptions.

The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).

• 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

• Capital expenditure costs are low, because is open-source and free
• Operational expenditure costs are medium because it's necessary [to have] an IT team with experience in Linux
• First step to the virtualization world. Wake up, we are in the 21st century
