Although you may establish a dependable, fast connection to MS Azure away from the public internet with the aid of an Azure ExpressRoute, it is fundamentally different from a traditional VPN connection over the internet. The table below highlights the most significant variations.
ExpressRoute Connectivity Options
With the help of four distinct network connectivity options, ExpressRoute provides private peering.
Point-to-Point Network Model
A dedicated connection between two points, like between an on-premises data center and/or an Azure region, is established by an organization under this model. This connection, which is not shared with other organizations, can send data between the two points.
Any-to-Any Network Model
According to this model, to connect to other networks and services, an organization must first create a connection to an exchange point like a network exchange or internet exchange. Organizations may communicate data with various partners thanks to this model, which enables them to build connections with numerous partners and service providers.
Virtual Cross-Connection Network Model
This model and the any-to-any model are comparable. However, instead of a physical cable, it uses virtual cross-connections, which are logical connections that let organizations connect to several networks and services.
ExpressRoute Direct Connection
The on-premises resources of an organization are connected to Azure over a dedicated, private connection under this model. This connection is established via a private circuit or leased line and is not shared with other organizations. Because it provides high-bandwidth, low-latency connectivity, this model benefits organizations that need to transmit significant volumes of data between their on-premises resources & Azure.
Azure ExpressRoute Features
Here are a few of Azure ExpressRoute’s key features.
Connectivity To Different Azure Regions
ExpressRoute supports different Azure regions. These are geographically dispersed data centers with networking, processing, and storage capabilities. Users choose a certain place when Azure builds a specific resource. Which Azure data center or region the resource is produced in depends on its storage location.
ExpressRoute from Microsoft leverages the BGP (Border Gateway Protocol) standard protocol to support dynamic routing. Routes may be exchanged between local networks, Azure instances, and publicly accessible Microsoft addresses. In addition, the network can set up several BGP sessions for various data traffic profiles.
If users enable a local SKU, ExpressRoute may be used for cheap data transfers. (stock-keeping unit; here: unique identification). Thanks to local SKUs, the data may be sent to one of the ExpressRoute locations near the desired Azure region. Data transmission is already included in the port price as a component of ExpressRoute Local.
ExpressRoute Global Reach
Exchanges between several local locations may be made using the ExpressRoute Global Reach function. It is employed, for instance, when users run many private data centers in various locations. Using ExpressRoute connections, these data centers may be linked. The Microsoft network is used to carry the generated data traffic between data centers.
ExpressRoute Direct provides physical isolation as an option to address the difficulties of many sensitive sectors. This physical seclusion is especially well suited for communicating private information in businesses like banking or government organizations. Additionally, power distribution may be accurately managed and customized to the needs of various business units.
ExpressRoute Main Benefits
ExpressRoute allows private, high-bandwidth, low-latency networking between Azure regions or Azure and on-premises data centers. Compared to connecting to Azure through the open internet, it gives several advantages.
ExpressRoute provides sophisticated multi-layer security protections to safeguard your resources. Additionally, since connections do not use the open internet, they are less susceptible to security threats and assaults.
For applications needing quick reaction times, ExpressRoute connections offer lower latency than connections over the open internet, which might be beneficial. At one of the ExpressRoute sites, each connection in ExpressRoute has two connections, each with two MSEEs (Microsoft Enterprise Edge Routers). Additionally, users have the option to choose not to provide redundant connections. However, redundant equipment is used by connectivity providers themselves. It is done to ensure that Microsoft receives a redundant connection.
It is beneficial for applications that need to move a lot of data since ExpressRoute connections can provide more bandwidth than is generally accessible via the public internet.
Better Compliance And Control
ExpressRoute can assist organizations in meeting compliance demands that a shared internet connection might not be able to. In addition, organizations may modify their network infrastructure to meet their unique needs with ExpressRoute, giving them more control over it.
Integration With On-premises Resources
Organizations may effortlessly combine Azure services with their on-premises resources thanks to ExpressRoute service. In addition, using Azure ExpressRoute, existing data centers’ capacity may be increased or linked.
