On our Day 4 Live Session, we covered Azure VPNGateway , Express Route

The previous week In Day 3 session we covered about Azure Networking and VNet peering.

Two weeks before In Day 2 session we covered about Azure Resource Manager, Subscriptions, NSG, and PowerShell.

Three weeks before In Day 1 session we covered about Azure Cloud Fundamentals, App Services, and Scaling Strategies

VPN Gateway

VPN Gateway in Azure establishes a safe and encrypted connection over the public internet between your on-premises network and Azure’s virtual network. It allows for smooth communication and data transfer while protecting data privacy and security. VPN Gateways, which support both Site-to-Site VPN and Point-to-Site VPN configurations, allow you to connect your whole on-premises network or specific devices to Azure services. This enables organisations to build hybrid environments, expand their network infrastructure, and utilise Azure services while maintaining a secure and dependable connection. VPN Gateways are critical in allowing secure connection between on-premises resources and Azure services, hence enabling effective hybrid cloud deployments and remote access scenarios.

Types of VPN gateway:

Site-to-Site VPN: A VPN Gateway that connects your on-premises network to an Azure virtual network. It establishes a safe and encrypted connection over the public internet, allowing your network infrastructure to be extended inside Azure.
Point-to-site VPN: It is used for Individual devices (such as laptops or mobile devices) which can securely connect to an Azure virtual network via Point-to-Site VPN. This is important for remote access scenarios, allowing users to access Azure resources from anywhere.

Q1) What is the advantage of using Azure VPN Gateway?

Ans. Azure VPN Gateway provides a secure and reliable way to extend on-premises networks into Azure or connect remote users/devices to Azure resources. It enables remote access, hybrid cloud scenarios, and secure communication without exposing sensitive data to the public internet.

Q2) Is VPN and VPN gateway same?

Ans. No, both are not same. A VPN is a service that creates a secure connection between two or more networks over the internet, while a VPN gateway is a device that creates a VPN connection. VPN gateways are always located in the cloud and are more reliable than VPNs, which can be located on-premises or in the cloud. VPN gateways are also easier to manage, as they can be managed from the Azure portal.

Q3) What is the difference between Point-to-Site and Site-to-Site VPN connections?

Ans. Point-to-Site VPN connects individual devices(laptops or mobiles) to Azure resources, while Site-to-Site VPN connects entire on-premises networks to Azure, extending your network infrastructure to the cloud.

Q5) What are the bandwidth options for VPN Gateway?

Ans. It offers a various bandwith options for VPN Gateway .

Basic: 100 Mbps
VpnGw1: 650 Mbps
VpnGw2: 1 Gbps
VpnGw3: 1.25 Gbps
VpnGw4: 2.5 Gbps
VpnGw5: 5 Gbps

Express Route

ExpressRoute is a service that connects your on-premises data centre or network environment to Microsoft’s Azure cloud services via a dedicated and private network connection. When compared to traditional internet-based connections, it provides a more dependable, low-latency, and higher-throughput connection.
Benefits of ExpressRoute

A connectivity provider can provide Layer 3 connectivity between your on-premises network and the Microsoft Cloud. An IPVPN network, a point-to-point Ethernet connection, or a virtual cross-connection via an Ethernet exchange can all provide connectivity.
Access to Microsoft cloud services across the entire geopolitical region.
The ExpressRoute premium add-on provides global connectivity to Microsoft services across all geographies.
BGP-based dynamic routing between your network and Microsoft.
Redundancy is built throughout every peering site for increased reliability.
SLA for connection uptime.

Q1) What are the benefits of using ExpressRoute?

Ans. ExpressRoute has advantages such as better network performance, enhanced data privacy and security, dependable connectivity, easy hybrid cloud integration, and quick data transfers, making it ideal for mission-critical applications and workloads.

Q2) Difference between Express Route and VPN gateway?

Ans. ExpressRoute provides dedicated and private high-speed connections between on-premises networks and Azure, ensuring dependable and secure communication while avoiding the use of the public internet. It’s ideal for data-intensive applications, real-time communication, and hybrid cloud integration because it has low latency and high performance. VPN Gateway, on the other hand, creates encrypted connections over the public internet and can be used for remote access or site-to-site connections. It is also more scalable and cost-effective than ExpressRoute. The choice between them is determined by performance, security, and connection requirements.

Q3) What are some common use cases for ExpressRoute?

Ans. ExpressRoute is appropriate for scenarios including as data migration, disaster recovery, operating latency-sensitive applications, privately accessing Azure services, and building hybrid cloud architectures.

Q4) What connection speeds are supported for ExpressRoute?

Ans. Supported connection speeds in express route are 50 Mbps, 100 Mbps, 200 Mbps, 500 Mbps, 1 Gbps, 2 Gbps, 5 Gbps, 10 Gbps.

Q5) What is the limit of Express Route?

Ans. ExpressRoute takes up to 4000 private peering prefixes and 200 Microsoft peering prefixes. When utilising ExpressRoute premium, you can boost the limit for private peering to 10,000 routes.

Q6) How can I modify the bandwidth of an ExpressRoute circuit?

Ans. You can do using the Azure portal, REST API, PowerShell, or Azure CLI.

Q7) Difference between VPN gateway and Express Route?

Ans.

Feature	VPN Gateway	Express Route
Connection Type	Public Internet	Private Connection
Bandwith	Up to 10 Gbps	Up to 100 Gbps
Reliability	Can be affected by congestion and latency on the public internet	More reliable, as it is a dedicated connection
Security	Traffic is encrypted over the public internet	Traffic is encrypted over a private connection
Cost	Less expensive	More expensive

Q1)What is an Azure VPN gateway?

Ans. An Azure VPN Gateway is a Microsoft Azure cloud-based networking solution that provides secure and private communication between on-premises networks and Azure virtual networks. It acts as a gateway for Virtual Private Network (VPN) connections, allowing data to be securely sent via the internet or dedicated connections.

Q2)What is the difference between a site-to-site connection and point-to-site?

Ans. A Site-to-Site (S2S) VPN connection creates a secure link between an on-premises network and a cloud network, allowing for seamless resource integration. A Point-to-Site (P2S) VPN connection, on the other hand, enables individual devices to securely access a cloud network remotely, making it perfect for remote worker access and smaller-scale connectivity requirements.

Q3)What is the Azure ExpressRoute route?

Ans. Azure ExpressRoute is a unique Microsoft Azure service that uses a global network of connectivity partners to provide a private, high-performance link between your on-premises network and Azure's cloud architecture. This allows safe, dependable, and low-latency connectivity for essential workloads and hybrid scenarios, effortlessly extending your network into the cloud and providing benefits such as direct access to Azure services and network isolation.
