Azure Networking Fundamentals

Azure Networking is a crucial component of Microsoft Azure, providing a robust and scalable platform for networking in the cloud. This article covers the fundamentals of Azure Networking, including key concepts, services, and best practices.

Key Concepts

• Virtual Network (VNet): A virtual network in Azure allows you to create a private, isolated network in the cloud.
• Subnet: A subnet is a range of IP addresses within a VNet that can be used to host resources.
• Public IP Address: A public IP address is a unique address assigned to a resource in Azure that is accessible from the internet.
• Private IP Address: A private IP address is used within a VNet and is not accessible from the internet.

Azure Networking Services

• Azure Virtual Network Gateway: Provides secure and scalable connectivity between your on-premises network and Azure.
• Azure VPN Gateway: Establishes a secure, encrypted connection between your on-premises network and Azure.
• Azure Load Balancer: Distributes incoming traffic across multiple VMs to ensure high availability and scalability.
• Azure NSG (Network Security Group): A security rule set that controls inbound and outbound traffic to network interfaces (NICs) and VMs.

Best Practices

• Always use private IP addresses for resources that do not need to be accessible from the internet.
• Use NSGs to control inbound and outbound traffic to your resources.
• Use Azure Virtual Network Gateway for secure connectivity between your on-premises network and Azure.
