Azure Networking AZ 700

 Connecting on-premises networks to the cloud is a critical aspect of hybrid cloud architecture. This connectivity allows organizations to extend their existing IT infrastructure into the cloud, ensuring seamless communication and integration between on-premises resources and cloud services. Here are the primary methods and services used to achieve this connectivity in Azure: ### Methods of Connecting On-Premises Networks to Azure 1. **Site-to-Site VPN**    - **VPN Gateway**: Azure VPN Gateway connects on-premises networks to Azure VNets over an IPsec/IKE (IKEv1 and IKEv2) VPN tunnel.    - **Advantages**: Cost-effective, easy to set up.    - **Use Cases**: Suitable for development and testing environments, small to medium-sized deployments. 2. **ExpressRoute**    - **Azure ExpressRoute**: Provides a private, dedicated connection between on-premises networks and Azure. It does not go over the public internet, offering higher security, reliabil...

 Azure offers a comprehensive suite of networking services designed to provide secure, reliable, and high-performance connectivity for your applications and resources. Here is a list of key Azure networking services: ### Azure Virtual Network (VNet) - **Azure Virtual Network (VNet)**: The fundamental building block for private networks in Azure. VNet enables many types of Azure resources to securely communicate with each other, the internet, and on-premises networks. - **Subnets**: Segments within a VNet to organize and secure resources. - **Network Security Groups (NSGs)**: Control inbound and outbound traffic to network interfaces (NIC), VMs, and subnets. ### Connectivity - **VPN Gateway**: Provides secure cross-premises connectivity between your Azure VNets and on-premises networks. - **Azure ExpressRoute**: Dedicated, private connections between your on-premises networks and Azure data centers, offering more reliability, faster speeds, and lower latencies compared to typical in...
