Module 4: Azure Networking

Introduction to Azure Virtual Network (VNet)

Azure Networking provides a range of services to connect your Azure resources to each other and to the internet securely. It includes services such as Azure Virtual Network, Azure Load Balancer, Azure VPN Gateway, and Azure DNS. Azure Networking allows you to build complex network architectures to meet your application’s needs, with features for security, performance, and availability.

Azure Load Balancer and Application Gateway

Azure Load Balancer is a vital tool for distributing incoming network traffic across multiple instances or services within a load-balanced set. Operating at Layer 4 of the OSI model, it ensures even traffic distribution, optimizing resource utilization and improving application availability. For example, in a web application scenario, Azure Load Balancer can evenly distribute incoming HTTP requests among multiple web servers to handle varying levels of traffic.

Real-life scenarios: Setting up secure network connections

– Hybrid Cloud Connectivity: Businesses use Azure Networking to connect their on-premises network to Azure, enabling seamless communication between the two environments.

– Global Load Balancing: Businesses use Azure Load Balancer to distribute traffic across multiple regions, ensuring optimal performance and availability for their global applications.

Connecting Azure VNets with on-premises networks

Azure Virtual Network (VNet) allows you to create private, isolated networks in Azure. Connecting Azure VNets with on-premises networks is crucial for establishing hybrid network environments, enabling seamless communication between Azure resources and on-premises infrastructure.

Lessons Learned: Network optimization strategies

– Azure Virtual Network: Azure Virtual Network allows you to create private networks in Azure, enabling secure communication between your Azure resources and on-premises networks.

– Azure Load Balancer: Azure Load Balancer distributes incoming network traffic across multiple VM instances to ensure high availability and reliability for your applications.
