Cloud Architecture
Make the target state visible across network, identity, compute, data and operations.
What is cloud network architecture?
Cloud network architecture is the design of how cloud workloads, users, services and external systems communicate securely and reliably. It defines network boundaries, address spaces, routing, internet and private connectivity, DNS, load balancing, security controls and the paths traffic follows between environments. Good cloud network architecture is not just a diagram. It connects network design to identity, application dependencies, resilience, observability and the way the environment will be operated.
Network segmentation
Separate workloads and environments using VPCs or virtual networks, subnets, routing domains and security boundaries that match ownership and risk rather than arbitrary resource groups.
Connectivity design
Plan internet access, private endpoints, peering, transit, VPN or dedicated connectivity around the systems that actually need to communicate and the failure modes those links introduce.
Traffic and service paths
DNS, ingress, load balancing, service discovery and egress controls should make application traffic predictable enough to troubleshoot and secure.
Security controls
Network policy, firewalls, security groups, private connectivity and identity-aware controls work together to reduce unnecessary exposure without blocking legitimate service communication.
Resilience and failure domains
Availability zones, regions, redundant paths and dependency behavior should be designed around the service recovery objectives rather than assumed from provider defaults.
Network observability
Flow logs, DNS telemetry, load-balancer health and service metrics help operators distinguish network failures from application or dependency failures.
Cloud network architecture should support the operating model.
On AWS that may include VPC topology, Transit Gateway, Route 53, private endpoints, load balancers and hybrid connectivity. On Azure it may include virtual networks, hub-and-spoke or Virtual WAN, Private Link, Azure DNS, application gateways and ExpressRoute. The specific services matter less than whether the architecture gives applications clear connectivity, controlled exposure, observable traffic paths and a design teams can operate over time.
Identity
Cloud Architecture work is shaped around the systems that matter, the people who run them and the outcome the business needs.
What Cloud Architecture can include.
Create a target architecture that connects applications, data, security and operations.
What Cloud Architecture can include.
Create a target architecture that connects applications, data, security and operations.
Network topology
Cloud Architecture scope is shaped by the current environment, the business objective and the dependencies that must remain stable. The capability areas below show the technical work most directly connected to this service.
Identity
Cloud Architecture work is shaped around the systems that matter, the people who run them and the outcome the business needs.
Compute
Identity, networking, workloads, automation and operations are designed together so the environment remains understandable after launch.

Resilience
The work produces a target architecture with major dependencies, security boundaries, availability assumptions and operating responsibilities made clear. The architecture is then used to guide implementation, review and future change rather than existing only as a diagram.

Cloud architecture is useful when individual design decisions are being made without a shared target state. Networking, identity, compute, data, resilience and observability need explicit relationships so teams understand how the environment is expected to behave.
