Impact on Other Customers
This project serves as a Reference Architecture for any global organization with a multicloud strategy.It validates the efficient deployment of virtual routers and firewalls (Cisco CSR 1000V and ASAv) on a global interconnection platform, ensuring the network keeps pace with the speed of digital business.
1. The Digital Infrastructure Foundation: Platform Equinix
Before exploring the solution, it is essential to understand its foundation.
Equinix is not merely a data-center operator it is a global, neutral interconnection platform built to accelerate digital ecosystems.
Figure: Founded in 1998, Equinix created a space for interconnection the exchange of traffic among networks and enterprises.
The International Business Exchange (IBX) is more than a data center; it is a marketplace where customers transact, collaborate across borders, and create new value
Figure: Over more than 20 years, Equinix has become the platform of choice for digital leaders in internet, e-commerce, and cloud ecosystems.
Global Scale and Service Pillars
Equinix’s connectivity strategy is inherently global:
Three service pillars at the heart of modern interconnection design:
- Data Center Services: IBX Data Centers and xScale Data Centers
- Interconnection Services: Equinix Fabric, Equinix Internet Exchange, and Cross Connects
- Digital Infrastructure Services: Network Edge (NFV) and Equinix BareMetal
Figure: Integrated Equinix Services
2. The Imperative of Network Decentralization
The network is no longer just a cost center it is the foundation for creating digital value.
Where and how you connect are strategic assets.
Legacy architecture is obsolete.
Centralizing security and backhauling all traffic to a primary data center causes congestion and high international bandwidth costs.

Cisco–Equinix Solution: Geographic Distribution of Network and Security
- Immediate Advantage: Optimized data paths for multicloud environments
- Distributed Control: Security enforcement at the Cloud Edge
Digital Core and Digital Edge Strategy
Segmenting the network by latency and processing ensures optimal performance:
- Digital Core: Hub adjacent to the cloud, focused on high-speed interconnection and global latency <50 ms for enterprise networks, partners, and multicloud integration
- Digital Edge: Hub adjacent to the user/IoT source, focused on real-time processing with latency <10 ms for IoT, video, and user transactions

Multicloud Ecosystem in the IBX
The Digital Core is implemented within IBX® through direct interconnection, providing access to multiple carriers and public-cloud providers (AWS, Azure, Google Cloud, IBM Cloud, Oracle Cloud).
Figure: This physical proximity guarantees low-latency networking and design flexibility for hybrid and multicloud environments.
3. Cisco SD-WAN and Platform Equinix: Engineering the Connection
The Cisco–Equinix partnership ensures enterprises can achieve high-performance, secure hybrid/multicloud environments.
Cisco SD-WAN Cloud onRamp for Colocation
This architecture converges all users and networks at the interconnection edge:
- Cisco SD-WAN Fabric, legacy WANs (MPLS/L3 VPN), and remote users (AnyConnect) meet at Equinix, acting as a Service Exchange Point.
Traffic is intelligently routed and secured to:
- IaaS: AWS, Azure, Google Cloud
- SaaS: Cisco Umbrella, Microsoft 365, and more
Objective: Consolidate routing and security management at a single control point before distributing traffic to the cloud, maximizing agility, performance, and cost optimization.
Network Edge (NE) and NFV
Equinix Network Edge transforms network provisioning from months to minutes:
- Pure Agility: Operational platform for virtual appliances, eliminating hardware lead time
- Bundled Services: Pre-integrated with Equinix Fabric and Equinix Connect for internet access
Cisco Appliances on NE
