Azure Virtual Networks (VNets) enable you to create logically isolated networks within the Azure cloud. They provide secure communication between Azure resources and can be segmented into subnets for better organisation and security. VNets support features like private IP addresses, network security groups, and user-defined routes to customise network traffic flow.
VPN Gateways allow you to establish secure site-to-site or point-to-site connections between your on-premises network and Azure VNets. This is crucial for hybrid networking solutions where workloads are spread across cloud and on-premises environments. VPN Gateways support various VPN protocols, ensuring encrypted data transmission over public networks.
Azure ExpressRoute provides a private, dedicated connection between your on-premises infrastructure and Azure data centres. This connection offers greater reliability, faster speeds, and lower latencies compared to standard internet connections. ExpressRoute is ideal for high-performance and high-security applications, ensuring seamless integration with your existing network.
Azure Load Balancer distributes incoming network traffic across multiple virtual machines (VMs) or services to ensure high availability and reliability. It supports both TCP and UDP traffic, making it versatile for different types of applications. The load balancer helps in maintaining service continuity during high traffic volumes or server failures.
Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. It includes features like SSL termination, URL-based routing, and a web application firewall (WAF) to protect against common web vulnerabilities. The Application Gateway optimises HTTP(S) traffic and enhances application performance and security.
Azure Traffic Manager uses DNS-based traffic routing to distribute requests across multiple endpoints globally. It improves application responsiveness by directing users to the closest or best-performing endpoints. Traffic Manager supports various routing methods, including performance, geographic, and failover, to meet different business requirements.
Network Security Groups are essential for controlling network traffic in Azure. They allow you to create rules that filter inbound and outbound traffic to and from Azure resources. By defining security rules based on IP addresses, ports, and protocols, NSGs help you enforce network security and protect your applications from unauthorised access.
Azure Firewall is a managed, cloud-based network security service that protects your Azure Virtual Network resources. It offers advanced threat protection with features like stateful packet inspection, filtering based on application and network rules, and threat intelligence integration. Azure Firewall ensures comprehensive security across your Azure environment.
Azure Monitor provides a full stack of monitoring capabilities to ensure the reliability and performance of your network infrastructure. It collects and analyses telemetry data from your Azure and on-premises resources. With features like log analytics, application insights, and alerts, Azure Monitor helps you detect and diagnose issues, ensuring optimal network performance and availability.
