The primary difference between Azure Functions and Logic Apps is that Logic Apps offers a visual designer and a wide array of connectors for integrating various services without code, while Azure Functions is a serverless compute service where you write custom code to handle events or respond to triggers.

Example of a simple Logic App workflow triggered by an HTTP request:

• In the Azure portal, create a Logic App.
• Open the Logic App's Designer and search for the "HTTP" connector in the search box.
• Choose the "When a HTTP request is received" trigger and add it to your workflow.
• Configure the trigger as needed (e.g., add JSON schema for expected input).
• Add an action to the workflow, such as "Send an email" using the Office 365 Outlook connector or any other action you prefer.
• Configure the action with the necessary inputs, for example, set the "To" and "Subject" properties of the email.
• Save the Logic App and grab the HTTP POST URL from the "When a HTTP request is received" trigger.
• Send an HTTP POST request to that URL with the appropriate data, and the Logic App will execute the workflow.

As a result, when an HTTP request is received, the email action will be executed based on the provided parameters.

Azure VPN Gateway and Azure Virtual WAN are networking solutions provided by Microsoft Azure, but they differ in terms of their capabilities and limitations.

Azure VPN Gateway is a service that offers secure connectivity between on-premises networks and Azure resources, using various types of VPN connections. However, it is limited to a maximum of 30 tunnels which makes it suitable for small-scale VPN connections.

In contrast, Azure Virtual WAN is a more comprehensive networking solution to connect multiple on-premises networks, Azure VNets, and remote sites. It can connect up to 1,000 branch connections per virtual hub with an aggregate of 20 Gbps per hub. This makes it suitable for large-scale VPN connections as it provides a more scalable and flexible networking solution.

Azure SQL Database is a fully managed, intelligent, and scalable cloud relational database service provided by Microsoft Azure that uses the Microsoft SQL Server engine. It offers built-in intelligence, high availability, dynamic scaling, and robust security features for data protection.

Example of performing CRUD operations using Entity Framework Core in a .NET Core application:

• Create a new .NET Core application and install the NuGet packages:

• Add a new connection string in appsettings.json:

• Create your model class (e.g., Customer.cs):

• Create a new ApplicationDbContext class that inherits from DbContext:

• In Startup.cs, add the following code to the ConfigureServices method:

• Run dotnet ef migrations add InitialCreate and dotnet ef database update to create the initial table schema in your Azure SQL Database.
• Now, you can perform CRUD operations, such as:

With this setup, you can perform CRUD operations on the Customer table in the Azure SQL Database using Entity Framework Core in your .NET Core application.

Azure Resource Graph service is designed to extend Azure resource management through highly performant and efficient resource exploration. It provides the capability of querying at scale over a specified subscription set to allow you to govern your environment effectively. It offers a unified API for querying Azure resources, regardless of the service or resource type.

Azure Logic Apps has two pricing plans: Consumption and Fixed. In the Consumption plan, you only pay for the executed action runs and trigger executions. It automatically scales with the number of executions and provides a shared environment. The Fixed plan offers dedicated throughput for your Logic Apps with predictable costs by using Integration Service Environment (ISE), which is ideal for scenarios with higher scale, isolation, and security requirements.

Example of creating a simple Logic App using Fixed plan:

• Create an Integration Service Environment (ISE) in the Azure portal.
• Create an empty Logic App within the ISE.
• Design your Logic App workflow as needed by adding triggers, actions, and connectors.
• Save and deploy the Logic App.

Once deployed, the Logic App will run using a dedicated environment with the specified fixed throughput.

Azure Data Lake Storage Gen2 is a scalable and cost-effective data lake storage solution built upon Azure Blob Storage. It provides advanced features such as hierarchical namespace support, high-performance, and fine-grained security to optimize the processing of big data and analytics workloads.

Example of creating a Data Lake Storage Gen2 account using Azure CLI:

Azure Virtual Machines Scale Sets makes it possible to build and manage a group of identical, load-balanced VMs in an elastic and automatically-scalable fashion based on defined rules and thresholds. It simplifies the deployment, management, and scaling of applications, ensuring high availability and performance.

Example of creating a Virtual Machine Scale Set using Azure CLI:

Example of training a simple model using the Azure Machine Learning Python SDK:

• Install the azureml-sdk Python package: pip install azureml-sdk
• Configure the training environment in your Python script:

• Prepare your training script (e.g., train.py). For example:

• Configure and submit the training run:

This example trains a simple logistic regression model on the Iris dataset using the Azure Machine Learning Python SDK and stores the trained model in the outputs folder.
