Connect your offices to Azure securely.

Azure networking is the set of services that connect your Azure resources to each other, to your offices and to the internet. At its core is the Azure Virtual Network, a private network in the cloud with its own address ranges, subnets and security rules.

It is the foundation of any Azure deployment. Servers placed in a well designed network are reachable only by who should reach them. A badly designed one exposes services to the internet or makes it impossible for systems to talk to each other.

For businesses with offices, networking is also how Azure becomes an extension of your existing network. Staff in the office reach cloud servers as if they were next door, and cloud servers reach office systems when needed.

Common patterns include a hub and spoke design, where a central hub network holds shared services such as firewalls and VPN gateways, and separate spoke networks hold different workloads. It scales cleanly and keeps security controls in one place.

Name resolution, routing and security are all part of the design. DNS needs to resolve names across the cloud and the office. Route tables decide where traffic flows. Network security groups and firewalls decide what is allowed.

Good Azure networking protects the business. It keeps servers off the public internet, separates systems that should not communicate and gives you logs when something happens. That reduces the chance and impact of an attack.

It also determines performance and experience. A clean, direct connection with the right size and placement gives users fast access to cloud systems. A poor design causes slow applications and complaints.

Finally, it enables the hybrid model. Many businesses will keep some systems on site for years, and the network is what lets both worlds work as one.

A company with three offices connects each office firewall to an Azure hub network with site-to-site VPNs. File servers and applications run in Azure, all traffic passes through a central firewall, and remote staff use a point-to-site VPN. Adding a fourth office takes an afternoon.

This is an illustrative example of how the service is used, not a description of a specific client.
