Azure networking is a cloud-based networking service offered by Microsoft Azure. It provides various components that help businesses to connect their resources in the cloud and on-premises infrastructure. This article will explore the Azure networking components and their functions.

Subnets:

Subnets are a subdivision of a virtual network that allows businesses to organize their resources and apply network security policies. Subnets can be used to group resources that require similar network configurations or access controls.

Network security groups:

Network security groups (NSGs) filter traffic based on rules that allow or deny resource access. NSGs can be applied to subnets, network interfaces, or individual virtual machines, allowing businesses to enforce security policies at multiple levels.

Virtual network peering:

Virtual network peering enables businesses to connect virtual networks within the same region or across different regions. This allows businesses to create a global network infrastructure that spans multiple locations.

VPN Gateway:

VPN Gateway is a service that provides a secure connection between an on-premises network and a virtual network in Azure. It allows businesses to establish a secure and encrypted connection that can be used to access resources in the virtual network.

Azure ExpressRoute:

Azure ExpressRoute is a private and dedicated connection between on-premises infrastructure and Azure. It provides higher security and reliability than a VPN connection over the public internet. ExpressRoute can connect to Azure or Microsoft cloud services, such as Office 365 and Dynamics 365.

Azure load balancer:

Azure Load Balancer is a service that distributes incoming network traffic across multiple resources, such as virtual machines or virtual machine scale sets. It helps to improve the availability and scalability of applications and services running in the cloud.

Azure firewall:

Azure Firewall is a managed network security service that protects virtual networks. It allows businesses to create and enforce network security policies to control resource access.

Azure networking components offer comprehensive services that enable businesses to build secure and scalable network infrastructure in the cloud. Some critical components of Azure are virtual networks, subnets, network security groups, virtual network peering, VPN Gateway, Azure ExpressRoute, Azure Load Balancer, Traffic Manager, and Azure Firewall networking. By utilizing these components, businesses can connect their cloud and on-premises infrastructure resources to create a flexible and secure network infrastructure that meets their business needs.
