24. Monitor and troubleshoot virtual networking
Azure Monitor for Networks “Azure Monitor Network Insights provides a comprehensive view of health and metrics for all deployed network resources, without requiring any configuration. It also provides access to network monitoring capabilities like Connection Monitor, flow logging for network security groups (NSGs), and Traffic Analytics.” From <https://docs.microsoft.com/en-us/azure/azure-monitor/insights/network-insights-overview> Monitoring Networks Go to “azure Portal -> Monitor -> Networks” From here you can see your different networks and…
22. Secure Access to Virtual Networks
NSGs (Network Security Groups) “You can use an Azure network security group to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. For each rule, you can specify source and destination, port, and…
23. Configure Load Balancing
Introduction to Load Balancing What is a load balancer? “An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. You define a front-end IP configuration that contains one…
20. Implement and Manage Virtual Networking
Introduction to VNet Peering By default, a VM on one VNet cannot communicate with a VM on another VNet. You can setup peering relationship between the 2 networks to allow them to communicate. Peering must be setup to work in both directions Setting up Peering In this example we will setup the connection between the Virtual Networks: vSydney and vMelbourne…
