Azure Networking: Azure Networking refers to the collection of services in Azure that enables the creation and management of virtual networks, allowing users to connect and isolate their Azure resources securely. It includes features like virtual network peering, network security groups, and virtual network gateways.
Virtual Networks: Azure Virtual Networks provide a way to logically isolate and securely connect Azure resources. They act as your own private network in the cloud, allowing you to control IP address ranges, subnets, and security policies. Virtual networks are the foundation for creating multi-tier applications and establishing communication between resources.
Subnets: Subnets are a way to partition a virtual network into smaller address spaces. They allow you to further segment and organize resources within a virtual network, providing control over network traffic and network security. Subnets are used to group similar resources or isolate specific types of traffic.
Network Security Groups: Azure Network Security Groups (NSGs) provide granular network security control for Azure resources. They act as a basic form of firewall, allowing you to define inbound and outbound traffic rules based on protocols, ports, and source/destination IP addresses. NSGs help to secure virtual networks and protect resources from unauthorized access.
Azure Load Balancer: Azure Load Balancer is a traffic distribution service that distributes incoming network traffic across multiple resources, such as virtual machines, based on load balancing rules. It helps to improve availability and scale applications by evenly distributing traffic and preventing overload on individual resources.
Azure Application Gateway: Azure Application Gateway is a layer 7 load balancer that provides application-level routing and load balancing services. It can be used to optimize and secure web traffic to your applications by performing tasks like SSL termination, URL-based routing, and cookie-based session affinity.
Azure Traffic Manager: Azure Traffic Manager is a DNS-based traffic load balancer that distributes incoming traffic across multiple endpoints, such as Azure web apps, based on routing methods. It helps to improve availability and performance by directing users to the closest or healthiest endpoint based on their geographic location or performance measurement.
Azure VPN Gateway: Azure VPN Gateway is a virtual network gateway that provides a secure connection between your on-premises network and Azure virtual networks. It enables you to establish a site-to-site or point-to-site VPN tunnel, extending your on-premises network to the Azure cloud securely and privately.
Azure ExpressRoute: Azure ExpressRoute is a private connectivity option that allows you to establish dedicated connections between your on-premises network and Azure data centers. It provides a more reliable and low-latency connection compared to a typical internet-based connection, enabling faster data transfer and seamless hybrid cloud integration.
Azure DNS: Azure DNS is a hosting service for DNS domains. It allows you to manage and resolve domain names using the same scalable and highly available infrastructure that powers Azure cloud services. Azure DNS provides high-performance, reliable, and secure DNS resolution for your applications and services.
Azure Firewall: Azure Firewall is a managed network security service that provides a stateful firewall-as-a-service for Azure virtual networks. It filters network traffic using application and network layer rules, allowing you to define fine-grained access control, routing, and network segmentation policies. Azure Firewall helps to protect your Azure resources from unauthorized access and threats.
Azure Network Watcher: Azure Network Watcher is a monitoring and diagnostic service that provides insights into the health, performance, and security of Azure virtual networks. It allows you to monitor network traffic, troubleshoot connectivity issues, and gain visibility into network topology and metrics. Azure Network Watcher helps to ensure the reliability and optimal performance of your virtual networks.
