Q16. What is Azure Web Jobs? How they are different from Azure Functions?

Answer:

Azure WebJobs :

>> We can find Azure Web Jobs as follows Azure App Service > Create, Web App > Goto Settings "Azure Web Jobs"

>> Azure WebJobs is a feature of Azure App Service that allows you to run background tasks or scripts within the same instance as your web app.

>> Azure webjobs has no additional cost. its a part of Azure App Service Plan. 

>> Best Use case: Long running task or background process. 

>> Cost Model: Included in App Service Plan. 

>> Hosting: Runs with App Service. 

Azure Functions:

>> its a serverless compute service, use to run small piece of code. Highly scalable. 

>> Good choice of event driven architecture. 

>> Best use case: Event driven, serverless application. small piece of code. 

>> Cost Model: Consumption plan (Pay per use) or App Service Plan. 

>> Hosting: Runs without App service. Its a serverless service.

Q17. What is Tenant ID, Client ID and Client secret key in Azure AD?

Answer:

In Azure Active Directory (Azure AD), the Client ID, Tenant ID, and Client Secret Key are essential components for authenticating and authorizing 

applications.

Tenant ID

Definition: The Tenant ID is a unique identifier for your Azure AD tenant, which is essentially your organization’s directory in Azure.

Purpose: It is used to identify the directory that your application belongs to.

Client ID

Definition: The Client ID, also known as the Application ID, is a unique identifier assigned to your application when you register it in Azure AD.

Purpose: It is used to identify your application during authentication and authorization processes.

Client Secret Key

Definition: The Client Secret Key is a password-like value that your application uses to authenticate itself when requesting tokens from Azure AD.

Purpose: It is used in conjunction with the Client ID to securely authenticate your application.

We have multiple ClientID for single TentantID. ClientID is like application ID, there could be many applications in a single Tenant.
