Interview: Azure Fundamentals_Part 1

Part 1: Describe core Azure concepts

Subscriptions: A subscription groups together user accounts and the resources that have been created by those user accounts. For each subscription, there are limits or quotas on the amount of resources that you can create and use. Organizations can use subscriptions to manage costs and the resources that are created by users, teams, or projects.

You might choose to create additional subscriptions to separate:

• Environments:
• Organizational structures:
• Billing:

Resource groups: Resources are combined into resource groups, which act as a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.

Authorization:

By applying RBAC permissions to a resource group, you can ease administration and limit access to allow only what’s needed.

Azure Resource Manager

Azure Resource Manager is the deployment and management service for Azure.

When a user sends a request from any of the Azure tools, APIs, or SDKs, Resource Manager receives the request. It authenticates and authorizes the request. Resource Manager sends the request to the Azure service, which takes the requested action.

The benefits of using Resource Manager

With Resource Manager, you can:

• Manage your infrastructure through declarative templates rather than scripts. A Resource Manager template is a JSON file that defines what you want to deploy to Azure.

Azure regions and Azure availability zones

Keep in mind that there could be a cost to duplicating your services and transferring data between zones.

What is App Service?

App Service is an HTTP-based service that enables you to build and host many types of web-based solutions without managing infrastructure.
