Azure Networking Basics

When it comes to cloud computing, networking plays a crucial role in ensuring that your applications and services are accessible, secure, and performant. In the case of Azure, Microsoft's cloud platform, understanding the basics of networking is essential for building and managing your resources effectively.
Virtual Networks (VNets)
One of the fundamental networking components in Azure is Virtual Networks (VNets). A VNet is a representation of your own network in the cloud. It allows you to securely connect Azure resources, like virtual machines, to each other, the internet, and on-premises networks.
Subnets
Within a VNet, you can create subnets to segment your network into smaller, more manageable parts. Subnets allow you to group resources based on their function and apply network security policies at the subnet level.
Virtual Network Peering
Virtual Network Peering enables you to connect two VNets in the same region through Azure's backbone network. This allows resources in different VNets to communicate with each other as if they were on the same network.
Network Security Groups (NSGs)
NSGs are a key component of network security in Azure. They allow you to filter inbound and outbound traffic to your Azure resources based on IP addresses, ports, and protocols. By defining security rules in NSGs, you can control access to your resources and protect them from unauthorized access.
Load Balancers
Load Balancers in Azure distribute incoming network traffic across multiple resources to ensure high availability and scalability of your applications. They can be used to balance traffic between virtual machines, containers, or even Azure services like Azure App Service.
Virtual Network Gateway
A Virtual Network Gateway is used to establish secure connections between your Azure VNet and on-premises networks or other Azure VNets. It enables you to set up VPNs or ExpressRoute connections to extend your network securely into the Azure cloud.
These are just a few of the Azure networking basics that you need to understand to effectively design, deploy, and manage your resources in the cloud. By mastering these concepts, you can build robust and secure network architectures that meet your business needs.
