Virtual networks and address planning
Reserve non-overlapping address ranges, plan subnets for workload and platform needs, and document future expansion.

Azure Cloud Networking
Connect Azure workloads to each other and existing environments with clear routing, DNS, and security boundaries.
Understand the service
How does cloud networking in Azure work?
Azure networking provides the paths that connect workloads, users, platform services, and existing environments. The design must account for address space, segmentation, routing, name resolution, inbound and outbound access, private services, and troubleshooting. Network choices made early affect Landing Zones, AVD, AKS, application hosting, and migration options, so the target should reflect real traffic flows rather than diagrams alone.
Technical design
Network architecture areas
The architecture depends on workloads, identity, connectivity, and the operating model; there is no single design for every organization.
Topology and connectivity
Select hub-and-spoke or Virtual WAN patterns where appropriate, and define peering, VPN, or ExpressRoute requirements.
Routing and segmentation
Use route tables and network security groups to control paths and separate trust boundaries according to required traffic.
DNS and private services
Plan name resolution, private DNS zones, private endpoints, and the links needed for hybrid and cloud workloads.
Ingress, egress, and protection
Identify approved entry and exit paths, application publishing needs, inspection points, and egress restrictions.
Visibility and operations
Enable appropriate flow and diagnostic logs, document dependencies, and define ownership for network changes and incident triage.
From design to operations
How Rollitech designs cloud connectivity
We clarify scope, assumptions, and ownership before configuration, then validate the result and hand over usable operating guidance.
Map traffic and dependencies
Identify users, applications, data services, DNS, on-premises connections, and required inbound and outbound flows.
Choose a target topology
Document address space, segmentation, routing, connectivity, private access, and the security boundaries.
Implement and validate paths
Configure agreed network components and test name resolution, routes, access controls, and application reachability.
Document change and support
Provide diagrams, configuration records, escalation ownership, and guidance for future workload onboarding.
Before implementation
Network questions to resolve
- Will Azure use existing address ranges without overlap across connected environments?
- Which services need private connectivity, and how will DNS resolution work across locations?
- Where are traffic inspection, egress control, and network change approvals owned?
Connect Azure workloads with a network design that can be operated.
Bring current network diagrams, address ranges, and application flow requirements to the discussion.
