Experience

Practical architecture. Measurable outcomes.

Selected engagements that show how Vector Six leads, architects, and implements high-consequence infrastructure decisions.

Cloud Architecture

Building segmented WAN connectivity across multiple Azure regions.

A cloud environment spanning multiple Azure regions required consistent segmentation, scalable routing, and seamless integration between regional hub-and-spoke architectures.

Business Challenge

Segmented WAN connectivity was needed across multiple Azure regions without creating isolated, inconsistent regional architectures.

Architectural Approach

Designed a network overlay across Azure to integrate regional hub-and-spoke architectures while preserving segmentation and routing consistency.

Business Impact

Established a repeatable cloud networking model that accelerated regional expansion, simplified operations, and ensured consistent security policies across the Azure environment.

WAN & Security Edge Transformation

Reducing WAN cost by rethinking the architecture.

A large enterprise relied on dual MPLS circuits across 45 branch locations, with centralized security inspection and backhauled internet traffic. The cost problem was not simply carrier pricing. It was architectural dependency.

Challenge

Expensive private transport, centralized inspection, and SaaS access patterns that no longer matched the business.

Approach

Redesigned WAN and security edge using SD-WAN, NAT-DIA, cloud security, AAR, and regional Azure edge.

Business Impact

Approximately $1M annual reduction in branch connectivity cost with a more flexible architecture.

Cloud On-Ramp Transformation

Improving cloud connectivity while reducing recurring cost.

A global financial organization needed resilient cloud connectivity with strict uptime and latency requirements while facing rising carrier costs.

Challenge

Increasing demand for capacity, strict latency requirements, and escalating monthly recurring connectivity cost.

Approach

Performed cloud-region and data-center analysis, managed multi-vendor RFPs, and optimized providers.

Business Impact

Approximately $50K monthly recurring cost reduction with redundant multi-cloud connectivity.

SD-WAN Traffic Optimization

Improving performance by improving path selection.

A utility provider had deployed SD-WAN but continued experiencing inconsistent application performance across WAN and SaaS environments.

Challenge

Static path selection, poor SaaS experience, and backhauled SaaS access creating unnecessary latency.

Approach

Introduced Application Aware Routing, Cloud OnRamp for SaaS to the SD-WAN Implementation

Business Impact

Significantly improved application performance and reduced latency across WAN and SaaS environments.

Private Cloud Connectivity Transformation

Modernizing branch connectivity to Azure private cloud.

More than 50 branch locations required secure, resilient connectivity to a private Azure environment. The existing Azure Virtual WAN deployment introduced operational complexity and limited the organization's ability to fully leverage its Cisco SD-WAN investment.

Challenge

Provide resilient private-cloud connectivity for more than 50 branch locations while improving application performance, simplifying operations, and reducing dependence on Azure Virtual WAN.

Approach

Designed and implemented Cisco SD-WAN edge deployments in two Azure regions, replacing Azure Virtual WAN with a native SD-WAN architecture that extended application-aware routing, segmentation, and centralized policy into the cloud.

Business Impact

Delivered a simplified cloud networking architecture with consistent policy enforcement across all branch locations, improved application resiliency, reduced operational complexity, and established a scalable foundation for future Azure expansion.

Data Center Architecture Assessment

Evaluating a next-generation data center fabric against business priorities.

A growing enterprise faced with an upcoming datacenter refresh was evaluating a modern spine-leaf architecture built on Juniper implementing VXLAN BGP EVPN. While the proposed design offered significant technical advantages, the organization needed to determine whether the investment aligned with current business objectives and budget constraints.

Challenge

Evaluate whether the modern datacenter fabric would deliver sufficient business value to justify the expense compared to a classical Ethernet data center architecture.

Approach

Developed a complete spine-leaf architecture, produced detailed implementation designs, and prepared budgetary estimates while comparing the operational and financial tradeoffs against a traditional Ethernet design.

Business Impact

Enabled executive leadership to make an informed architectural decision. Based on cost, operational requirements, and projected growth, the organization elected to implement a classical Ethernet architecture while preserving a future migration path to EVPN as business needs evolve.

Architecture isn't an expense. It's the decision that determines every expense that follows.
