Amazon Elastic Compute Cloud (EC2) vs. Azure Virtual Machines

Suitable for companies that are looking for performance at a competitive price, flexibility to switch instance type even with RI, flexibility to add-on IOPS, option to lower running cost with the regular introduction of new instance type that comes with higher performance but at a lower cost.

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.

• A great variety of choices in Amazon Machine Image (AMI) types. Users can select a more basic type to run generic workloads, but also have the choice to pick an AMI pre-installed with specific services in the AWS Marketplace.
• The range of instance types can support the usage from a student's exploration (inexpensive general-purpose nano instances) to an enterprise's most intense workloads (memory or storage-optimized instances with terabytes of memory and ultra-fast network connection).
• The pricing options, from regular instances, reserved instances to spot instances allow users to get the job done and make smart choices about how much they want to pay and when they want to pay.

• 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

• This service is a bit difficult to consume. New users need a big learning curve to use this service effectively.
• UI for EC2 service is a little complex and at many places, it misses detailed explanation.
• Sometimes it takes too long to create images of EC2 instances. This keeps your EC2 up for that extra time. When instances are heavy, it penalizes a lot of money.

• 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.

It's easy and straightforward for a technical person to use it via SSH, but when working in cross-functional teams, using Amazon's web console is difficult for this particular service. Most modern cloud providers provide a more seamless user interface to interact with their cloud machines, and the same should have been the case with EC2.

They are very easy and intuitive, very easy to deploy

AWS's support is good overall. Not outstanding, but better than average. We have had very little reason to engage with AWS support but in our limited experience, the staff has been knowledgeable, timely and helpful. The only negative is actually initiating a service request can be a bit of a pain.

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 VM Builder offers good service, but the options are quite limited (Too much inclined to Windows as it is prepared by Microsoft). EC2 image building capabilities are the best in the market, and offer Windows, Linux (CentOS, rh2, debian, ubuntu), along with other distros, which helps customers choose according to their needs.

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.

• With EC2 you pay only when is Running, so you can save up to 75% on Dev environments which are running only on office hours
• You have several ways to pay for EC2, with EC2 Reserved Instances you pay with a discount of up to 72% if you make a commitment of using them from 1 or 3 years
• With EC2 spot you can use spare AWS EC2 capacity with a discount of up to 90%, your workload must be interrupt tolerant as your EC2 could be reclaim by AWS and the EC2 terminated

• 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
