One the question I get from academics and students is how does Microsoft Azure services compare to Amazon Web Services (AWS)?
At Microsoft we have built the following resources where you can compare the IT capabilities of Azure and AWS services across the following categories.
These resources are maintained as both AWS and Azure constantly updating services in some cases there are multiple Azure services listed for some AWS services.
One of the key differentiators from an academic perspective is Azure subscriptions are a grouping of resources with an assigned owner responsible for billing and permissions management. Unlike AWS, where any resources created under the AWS account are tied to that account, subscriptions exist independently of their owner accounts, and can be reassigned to new owners as needed.
Account Administrator - The subscription owner and the account billed for the resources used in the subscription. The account administrator can only be changed by transferring ownership of the subscription.
Service Administrator - This account has rights to create and manage resources in the subscription, but is not responsible for billing. By default, the account administrator and service administrator are assigned to the same account. The account administrator can assign a separate user to the service administrator account for managing the technical and operational aspects of a subscription. There is only one service administrator per subscription.
Co-administrator - There can be multiple co-administrator accounts assigned to a subscription. Co-administrators cannot change the service administrator, but otherwise have full control over subscription resources and users.
Below the subscription level user roles and individual permissions can also be assigned to specific resources, similarly to how permissions are granted to IAM users and groups in AWS. In Azure all user accounts are associated with either a Microsoft Account or Organizational Account (an account managed through an Azure Active Directory).
Guidance for setting up Azure in your institution
Like AWS accounts, subscriptions have default service quotas and limits.
For a full list of these limits, see Azure subscription and service limits, quotas, and constraints . These limits can be increased up to the maximum by filing a support request in the management portal .
