Conceptual routed spine–leaf data center
Two spines, three workload leaves and one border leaf. All four leaves connect to both spines. Border leaf connects to routing/firewall service edge, then enterprise WAN and selected hybrid cloud. Shared hypervisors host logically segmented workloads. Management links are representative out-of-band connections, not production traffic.

Architecture
How a Modern Data Center Network Works
A spine-leaf fabric separates the physical routed network from the logical networks your tenants and applications use. Select a layer to see how each part fits together.
Two-spine VXLAN EVPN fabric
Four workload leaf VTEPs and two border leaf VTEPs each have a routed link to both spines. In this chosen design both spines act as EVPN route reflectors. Both borders attach to the routing and firewall service edge. Tenant VM tags are logical workloads, not VRFs terminating on servers.

Chosen architecture: spines are EVPN route reflectors, leaves and borders are VTEPs. Dotted Leaf 1 sessions to both RRs and gray management paths are representative; the same RR pattern applies to all six VTEPs. VXLAN crosses the routed underlay, not a direct leaf cable. External security handoffs are conceptual; redundant edge implementation is engagement-specific.
Underlay
Every leaf connects to every spine with routed Layer 3 links. There is no fabric-wide Layer 2 broadcast domain, and ECMP can use eligible equal-cost routes when supported and available; recovery depends on routing and failure detection.
Overlay
VXLAN encapsulates tenant traffic between leaf VTEPs (data plane). BGP EVPN advertises MAC and IP reachability between them (control plane).
Tenant segmentation
VRFs isolate routing tables; L3 VNIs identify overlay routing contexts and L2 VNIs identify bridge segments. Segmentation alone is not a security or compliance guarantee. Traffic between tenants is permitted only where it is routed through defined policy points.
Network modernization
Modernize Your Data Center with VXLAN EVPN
Legacy designs stretch VLANs across core, aggregation, and access layers and rely on Spanning Tree Protocol to prevent loops — which blocks redundant links and makes large Layer 2 domains harder to scale and troubleshoot. A VXLAN EVPN fabric takes a different approach.
Underlay
A routed spine-leaf network that provides IP reachability and multiple equal-cost paths between leaves.
VXLAN
Encapsulation that carries Layer 2 or Layer 3 tenant traffic across the routed underlay, identified by a VNI.
BGP EVPN
The control plane that distributes MAC/IP and prefix information, reducing reliance on flood-and-learn.
VRFs & VNIs
Logical separation of tenants and applications on shared physical infrastructure.
Before
Traditional Layer 2 Data Center
- VLANs stretched across many switches create large failure domains
- STP blocks redundant links, leaving capacity unused
- Flood-and-learn behavior grows with the size of the domain
- Adding tenants often means manual VLAN changes on many devices
After
Modern VXLAN EVPN Fabric
- Routed underlay with equal-cost multipath across spines
- Layer 2 extended only where an application actually requires it
- EVPN control plane distributes host reachability
- Tenants added as VRF/VNI definitions — well suited to automation
Engineering note: STP is often still used at the edge for host-facing ports, and fabrics still require sound design and change control. Workload mobility between sites depends on virtualization, storage replication, latency, routing, and application requirements. Logical segmentation supports — but does not by itself guarantee — regulatory compliance; policy enforcement between segments is still required.

Each row is an independent alternative, not a requirement to connect all three clouds. IPsec paths are encrypted logical tunnels over the internet. Solid connectors indicate network transport / routing flow, not a single physical cable across the provider. BGP exchanges routes where configured; AWS VPN can also use static routing. Cloud Router is a control-plane service, not a packet-forwarding appliance. Private connectivity is not automatically end-to-end encrypted. Redundancy, attachments, route filtering and service scope must be designed per provider.
Network connectivity
VPN and private circuits carry traffic; each needs redundancy planning and correct routing.
Cloud identity & security
Cloud IAM, security groups, and posture management are configured in each provider's own tools.
Workload integration
Applications, DNS, and data flows are planned per workload — not every cloud is used or managed in every engagement.

Automation
Automating Modern Data Center Operations
Automation makes changes repeatable and consistent. It reduces manual effort and configuration drift — but it still depends on good design, validation, and change control.
-
Design
Define the intended state and reusable templates.
-
Validate
Review changes and check them against standards.
-
Deploy
Apply changes through approved tools in a window.
-
Verify
Run post-change checks and compare to intent.
-
Monitor
Track health, alerts, and configuration drift.
-
Improve
Feed lessons back into templates and design.
| Tool | Typical role | Where it fits |
|---|---|---|
| Terraform | Declarative, desired-state provisioning (Infrastructure as Code) | Cloud resources and API-driven platforms |
| Ansible | Configuration management and repeatable tasks | Network devices, servers, compliance checks |
| Python & APIs | Custom integrations, validation scripts, reporting | Gluing tools, monitoring, and workflows together |
| Cisco NDFC | Fabric management and orchestration | Cisco Nexus VXLAN EVPN data center fabrics |
| Cisco DNA Center | Intent-based automation and assurance | Primarily enterprise campus and branch networks |
Changes require approval, a maintenance window, post-change checks and a documented rollback plan. Automation reduces repetitive errors; it cannot eliminate configuration errors.
Cisco ACI is a separate, policy-driven fabric managed by its own controller (APIC) and is not the same platform as NDFC.
Resilience
Designing Data Centers for Resilience and Availability
Availability is designed, tested, and operated — not assumed. The right level of redundancy depends on your applications, budget, and recovery objectives.
- Redundant paths — dual uplinks and multiple spines
- HA infrastructure — paired devices and power feeds
- Failure domains — limit the blast radius of faults
- Routing resiliency — fast convergence and ECMP
- Change management — reviewed, scheduled, reversible
- Monitoring — detect degradation early
- Backup & recovery — tested restores and dependencies, see Backup & Disaster Recovery
Recovery depends on routing / detection; loss possible.

Illustrative Scenario
Illustrative Scenario: Multi-Tenant VXLAN Deployment for a Houston Enterprise
This example demonstrates how a multi-tenant VXLAN EVPN architecture could be designed and deployed in a Houston enterprise environment. It is a hypothetical scenario intended to illustrate technical concepts and potential implementation approaches, not an actual customer engagement.
The Challenge
Consider a Houston-based enterprise operating a legacy Layer 2 data center design. Multiple vendors and service partners might need access to different workloads, but a flat network could create risks of traffic overlap, compliance gaps, and downtime from Spanning Tree Protocol (STP) loops. Scaling such an environment can mean complex VLAN management, and moving workloads between sites can be slow and error-prone.
Proposed Solution:
- A proposed solution would involve designing and deploying a VXLAN EVPN fabric with Cisco NDFC orchestration to replace the legacy Layer 2 design.
- Implementing multi-tenant segmentation could give each partner and vendor isolated logical networks while running on shared physical infrastructure.
- Moving to a Layer 3 VXLAN overlay could help reduce STP issues and allow better use of available links (full link utilization) and redundancy.
- Supporting VM mobility across sites could preserve Layer 2 identity while allowing workload moves between data centers, subject to virtualization, storage, latency, and application requirements.
- Extending Layer 2 services across sites via VXLAN could allow distributed applications and databases to run across sites where their requirements permit.

Potential Outcomes:
- Tenant Isolation: The proposed design is intended to improve tenant isolation, reduce unintended cross-tenant connectivity, and support compliance objectives.
- Future-Ready Scalability: The proposed architecture could support future cloud extensions and infrastructure expansion, such as onboarding new vendors, with less need for redesign.
Key Takeaway: A VXLAN EVPN multi-tenant design could provide a scalable, vendor-ready data center fabric with stronger tenant segmentation, helping an organization work toward its security and compliance objectives. Actual results would depend on a formal assessment, the design, the implementation, and ongoing operations.

7. Do you offer compliance-ready solutions?
8. What is the difference between a traditional data center and a VXLAN EVPN fabric?
A traditional design typically relies on core, aggregation, and access layers with VLANs stretched across them and Spanning Tree Protocol blocking redundant links. A VXLAN EVPN fabric uses a routed Layer 3 spine-leaf underlay, VXLAN encapsulation to carry tenant traffic as an overlay, and BGP EVPN as the control plane that distributes host and route information. The result is a design where redundant links can be used through equal-cost routing and Layer 2 segments are extended only where they are actually needed.
9. Can existing Cisco, Arista, or Juniper networks be modernized without replacing everything?
Often, yes. Many modernization projects start with an assessment of current hardware, software versions, and support status. Some platforms can run VXLAN EVPN with a software upgrade; others may need to be replaced. A phased approach can connect the new fabric to the legacy network through border or transit links so workloads move in stages rather than all at once.
10. How does hybrid cloud connectivity work between an on-premises data center and AWS or Azure?
Common options include site-to-site IPsec VPN over the internet and dedicated private connectivity such as AWS Direct Connect or Azure ExpressRoute, which are typically delivered through a carrier, exchange, or colocation partner. Routing, address planning, segmentation, and cloud-side security controls must be designed on both ends. The right option depends on bandwidth, latency, resilience, cost, and compliance requirements.
11. What is the role of Terraform, Ansible, and NDFC in data center automation?
They solve different problems. Terraform is commonly used for declarative, desired-state provisioning, especially of cloud and API-driven resources. Ansible is commonly used for configuration management and repeatable task automation across devices and servers. Cisco Nexus Dashboard Fabric Controller (NDFC) is a fabric management and orchestration platform for Cisco Nexus VXLAN EVPN fabrics. Python and vendor APIs are used to integrate these tools and handle custom workflows.
12. How do you reduce risks during data center migrations and network cutovers?
Risk is reduced through discovery and dependency mapping, a documented target design, lab or staged validation where possible, phased migration waves, defined maintenance windows, pre- and post-change checks, and tested rollback plans. These steps reduce the likelihood and impact of disruption, but no migration can be guaranteed to have zero downtime.
