Transforming a global financial services enterprise

Migrating mission-critical technology from corporate data centers to a global Equinix colocation platform across the Americas, Europe, and Asia-Pacific.

Executive summary

A large global financial services organization had reached an inflection point in its technology strategy.

For years, the company had operated its technology infrastructure from a network of privately owned and operated corporate data centers on company campuses throughout the United States, Europe, and Asia-Pacific. Those facilities had been designed around a very different technology environment.

Over time, the technology footprint expanded dramatically. New applications, higher transaction volumes, expanding digital services, growing cybersecurity requirements, cloud adoption, regulatory obligations, increasingly distributed users, and demand for real-time access to financial data had transformed the company's infrastructure requirements. A global technology environment could no longer be effectively optimized around a collection of campus-based data centers.

The company made a strategic decision: exit its legacy on-campus data center footprint and establish a globally distributed technology infrastructure across Equinix data centers in North America, Europe, and Asia-Pacific.

This was not simply a data center relocation. It was a global infrastructure transformation. The program required the migration of core compute, storage, network, security, applications, databases, communications, and enterprise infrastructure while maintaining the availability and security expected of a global financial institution.

Arcellium served as the organization's technology transformation and migration partner, providing the program leadership, architecture, engineering coordination, migration planning, implementation, testing, and operational transition required to execute the transformation.

The result was a new infrastructure model built around global connectivity, geographic resiliency, scalability, security, performance, and operational flexibility.

The business challenge

A global financial institution outgrowing its campus data centers

Financial services organizations operate in an environment where technology is inseparable from the business. Trading platforms, payment systems, customer-facing applications, financial databases, risk systems, analytics, regulatory reporting, authentication, cybersecurity, communications, and enterprise applications all depend on highly available infrastructure.

For this organization, infrastructure availability was directly tied to its ability to serve customers, process transactions, communicate with financial markets, protect sensitive information, and operate across multiple time zones.

The legacy campus data centers had become increasingly difficult to operate and expand. The organization faced a combination of challenges:

The fundamental problem was no longer "How do we operate our data centers?" It had become:

How do we create a global infrastructure platform capable of supporting the future of the business?

The strategic decision

From campus data centers to global colocation

The organization determined that continuing to own and operate its own physical data center facilities was no longer the optimal strategy. Instead, it would move to a globally distributed colocation model using Equinix facilities across key markets in the United States, Europe, and Asia-Pacific.

The strategy let the organization retain control of its technology infrastructure while shifting the physical data center layer to a specialized global provider. That distinction mattered. The company was not simply "moving to the cloud." It retained ownership and control of its critical:

It used Equinix for the underlying data center environment and its extensive interconnection ecosystem. Equinix currently describes its platform as spanning hundreds of data centers across 70+ metropolitan markets, providing access to thousands of clouds, networks, and enterprises. For a global financial institution, that ecosystem was strategically significant.

Why Equinix?

Equinix gave the organization a global platform positioned around major financial, technology, telecommunications, cloud, and enterprise ecosystems. Equinix positions its financial-services infrastructure around private connectivity, predictable performance, regulatory considerations, data sovereignty, and proximity to financial-market ecosystems. Its global footprint also let the institution distribute infrastructure geographically rather than concentrating critical systems in a small number of corporate facilities.

A global architecture

The target architecture was designed around three primary geographic regions.

Americas

  • North American operations
  • Corporate systems
  • Financial applications
  • Customer-facing services
  • Cloud connectivity
  • Disaster recovery
  • Enterprise networking

Europe

  • European operations
  • Regional applications
  • Financial systems
  • Data-residency requirements
  • Regulatory workloads
  • Regional disaster recovery
  • European cloud connectivity

Asia-Pacific

  • APAC operations
  • Regional applications
  • Customer services
  • Financial-market connectivity
  • Regional infrastructure
  • Disaster recovery
  • Local cloud and telecommunications ecosystems

Equinix currently identifies 108 data centers across the Americas, 101 across Europe, the Middle East, and Africa, and 63 across Asia-Pacific. This geographic model let the organization move away from a centralized campus model toward a distributed infrastructure architecture.

The business rationale: infrastructure as a global strategic asset

Several strategic objectives drove the migration.

Increase resilience

Critical systems could be distributed across multiple geographic locations rather than relying on a limited number of corporate campuses.

Improve connectivity

Infrastructure could be positioned closer to financial exchanges, market data providers, payment networks, cloud providers, telecommunications carriers, business partners, customers, and regional offices. Equinix highlights its financial-services footprint and connectivity to financial markets as a core part of its platform.

Increase scalability

The organization could expand infrastructure capacity without first expanding its physical corporate data centers.

Reduce capital requirements

The company could shift investment away from facility infrastructure and toward technology that directly supported the business.

Improve operational agility

New technology infrastructure could be deployed within established Equinix facilities and connected to the required networks, clouds, and partners.

Support cloud adoption

The architecture provided a physical foundation for a hybrid and multicloud strategy.

Improve geographic flexibility

Infrastructure could be deployed in the geographic markets where business requirements demanded it.

The Arcellium difference

Global transformation requires more than a migration team

Moving a server from one building to another is relatively straightforward. Moving the infrastructure that supports a global financial institution is fundamentally different. The environment involved thousands of dependencies. A single application could depend on:

A failure in any one dependency could affect the business. Arcellium therefore approached the initiative as an enterprise transformation program, not a physical relocation project, structured around:

Discover → Assess → Architect → Design → Build → Test → Migrate → Validate → Stabilize → Optimize

Phase 1: Global discovery and assessment

Arcellium began by building a comprehensive inventory of the existing global technology environment. The assessment covered:

Dependency mapping

One of the most important activities was identifying application and infrastructure dependencies. Arcellium worked with application owners, infrastructure teams, network engineering, security, operations, and business stakeholders to determine:

This dependency analysis became the foundation for the migration-wave strategy.

Phase 2: Global target architecture

Arcellium then developed the target infrastructure architecture, which incorporated:

The design was deliberately distributed. Rather than recreating the old campus architecture inside a new building, Arcellium redesigned the infrastructure around a global operating model.

Phase 3: Equinix facility design

Each Equinix deployment required detailed engineering. Arcellium coordinated:

Standardized deployment patterns were developed wherever possible. This created consistency across the global footprint while allowing individual regions to accommodate local requirements.

Phase 4: Global network transformation

The network became the connective tissue of the new architecture. The organization needed secure, resilient connectivity between Equinix facilities, corporate offices, financial-market networks, cloud providers, Internet service providers, business partners, customers, regional operations, and disaster recovery sites.

Equinix's interconnection ecosystem provides physical and software-defined connectivity options across its global platform. Equinix describes Equinix Fabric as enabling private connectivity between distributed infrastructure, clouds, networks, and partners across the Americas, EMEA, and APAC. Arcellium incorporated those capabilities into the broader network architecture, producing a network designed around the organization's new global model rather than the limits of its legacy campus environment.

Phase 5: Cloud and hybrid infrastructure

The migration also created an opportunity to modernize the company's relationship with cloud platforms. Rather than treating cloud and physical infrastructure as separate environments, Arcellium designed the architecture around a hybrid model. The Equinix environment became an important physical foundation connecting:

Enterprise infrastructure ↔ Equinix ↔ Cloud platforms ↔ Financial networks ↔ Business partners ↔ Global offices

Private connectivity reduced dependence on public Internet paths for critical traffic and let the organization design connectivity around security, performance, and predictable network behavior. Equinix describes private interconnection as a core component of hybrid multicloud architecture and supports direct connections to major cloud providers.

Phase 6: Security transformation

Security was built into the migration rather than treated as a post-migration activity. Arcellium worked across network, infrastructure, security, and application teams to establish the required security architecture. Key areas included:

The new architecture allowed security controls to be standardized across the global environment while maintaining appropriate regional separation.

Phase 7: Regulatory and data residency considerations

A global financial services organization cannot treat every workload as geographically interchangeable. Data residency, jurisdictional requirements, operational resilience, privacy, and regulatory obligations can influence where systems and data are deployed. Arcellium incorporated geographic and regulatory considerations into migration planning, classifying applications and data by:

Equinix identifies jurisdictional control, data residency, DORA, GDPR, MiFID II, and other regional requirements as considerations for financial-services infrastructure. This let the organization build a global architecture without treating "global" as synonymous with "centralized."

Phase 8: Migration factory

Given the scale of the program, Arcellium established a repeatable migration methodology. Each migration wave followed a standardized process:

  1. Assess: identify systems, dependencies, owners, and requirements.
  2. Prepare: configure destination infrastructure and connectivity.
  3. Validate: perform technical and application testing.
  4. Communicate: confirm stakeholders, maintenance windows, and business readiness.
  5. Execute: perform the migration according to the approved runbook.
  6. Test: validate infrastructure, network, application, and business functionality.
  7. Stabilize: monitor the environment following migration.
  8. Accept: obtain application-owner and business approval.
  9. Optimize: address issues and improve the environment before the next wave.

This created a migration factory capable of executing repeated migrations across multiple countries and time zones.

Phase 9: Business continuity

For financial services, migration windows must be engineered around business operations. The organization could not simply shut down its global technology environment and move it. Arcellium coordinated migration activities around:

Migration windows were selected to minimize operational exposure. Rollback procedures were established for critical migration events, and business stakeholders took part in readiness and acceptance activities.

Phase 10: Regional migration waves

The global program was executed as a series of regional and application-based migration waves.

Americas

The Americas migration established the foundation for the North American infrastructure footprint. Core infrastructure, enterprise applications, networking, security platforms, and business systems moved into the target Equinix environments, and the architecture established connectivity to major cloud and financial ecosystems.

Europe

The European migration added considerations around regional operations, data residency, privacy, regulatory requirements, and business continuity. Arcellium coordinated the migration of regional infrastructure while maintaining connectivity to the organization's global technology platform. The European environment became an integrated part of the global architecture rather than an isolated regional data center.

Asia-Pacific

The APAC migration introduced another level of complexity. Multiple time zones, regional telecommunications environments, local applications, and distance from other infrastructure hubs required detailed planning. Arcellium coordinated infrastructure deployment, connectivity, application migration, testing, and stabilization across the region. The result was a globally connected platform able to support APAC operations without centralizing all infrastructure in North America or Europe.

Global operations model

Following the migration, the organization moved from managing a collection of campus data centers to managing a distributed global infrastructure platform. The operating model centered on:

This significantly changed how the technology organization could manage infrastructure.

Business benefits

Increased resilience

The organization gained the ability to distribute critical infrastructure across multiple geographic locations. This reduced dependence on individual corporate campuses and supported a broader business-continuity strategy.

Global scalability

The organization could deploy additional infrastructure in strategic markets without constructing new corporate data centers. Equinix supports deployments ranging from individual cabinets to large-scale environments, so footprints can expand with business requirements.

Improved connectivity

The organization gained access to a dense ecosystem of carriers, networks, cloud providers, enterprises, and financial services organizations. Equinix currently reports more than 500,000 interconnections across its global platform. For a financial institution, that ecosystem can provide significant architectural flexibility.

Reduced latency

Locating infrastructure closer to financial exchanges, customers, cloud providers, and market-data ecosystems can reduce network distance and improve application responsiveness. This is particularly relevant to financial applications where predictable network performance can be operationally important. Equinix positions its financial-services infrastructure around predictable, low-latency connectivity to financial-market ecosystems.

Improved cloud integration

The organization could connect its private infrastructure directly to major cloud providers without requiring every application to traverse traditional corporate networks. This provided a foundation for hybrid cloud, multicloud, cloud migration, cloud disaster recovery, analytics, digital services, and data platforms.

Reduced data center capital requirements

The organization could reduce its dependence on privately owned physical data center facilities. Capital that would otherwise have gone to buildings, electrical infrastructure, cooling, generators, physical security, and facility expansion could be redirected toward technology and business initiatives.

Operational standardization

One of the most significant benefits was standardizing infrastructure deployment across regions. Instead of every corporate data center having its own architecture and operating model, Arcellium established repeatable deployment standards. This improved deployment consistency, documentation, security, troubleshooting, asset management, operational support, and change management.

Improved security

The new architecture allowed security controls to be designed consistently across global infrastructure. Physical security, network segmentation, private connectivity, access control, monitoring, and centralized security operations could be built into the global operating model. Equinix identifies security, compliance, physical controls, and private connectivity as core components of its financial-services infrastructure offering.

Improved business continuity

Geographic distribution created additional options for designing active/active and active/passive architectures, regional disaster recovery, cross-region replication, backup, application recovery, and infrastructure recovery. Critical systems could be designed around geographic resiliency rather than relying primarily on a second corporate campus.

Integrating the pieces

The success of a global data center transformation does not depend on any single technology. It depends on the integration of hundreds of technologies and decisions. Arcellium served as the connective layer between:

Executive strategy → Business requirements → Enterprise architecture → Data center architecture → Network architecture → Security → Cloud → Applications → Infrastructure → Migration → Testing → Operations

This was one of the defining characteristics of the program. Arcellium didn't simply move equipment. It orchestrated the transformation of the organization's entire infrastructure operating model.

Program governance

Arcellium established the governance structure needed to manage a global transformation of this scale, incorporating:

This ensured that technology decisions remained aligned with business objectives.

Vendor and partner coordination

The program required coordination among many organizations. Arcellium served as the technical integration point among:

Arcellium's role was to ensure that every workstream ultimately converged into a functioning production environment.

The transformation

The organization moved:

From
To
A collection of corporate data centers
A globally distributed digital infrastructure platform
Facility ownership
Infrastructure consumption
Regional silos
Global connectivity
Fixed physical capacity
Scalable infrastructure
Data center-centric architecture
Application, cloud, network, and ecosystem-centric architecture

The result

The financial services organization successfully transformed its global infrastructure environment, migrating mission-critical technology from its corporate campus data centers into a distributed Equinix footprint across the United States, Europe, and Asia-Pacific. The transformation established a new technology foundation designed around:

The company was no longer constrained by the physical limits of its legacy campus data centers. It gained a globally distributed infrastructure platform capable of evolving with the business.

More than a data center migration

The program demonstrated that a global data center migration can become one of the most significant technology transformation opportunities available to an enterprise. The organization did not simply relocate servers. It redesigned how infrastructure supported the business, bringing technology closer to the financial ecosystems, cloud platforms, networks, partners, and customers that mattered most.

Equinix provided the global physical and interconnection platform. The financial institution provided the business strategy and technology vision. Arcellium provided the architecture, orchestration, engineering, and execution that brought the two together.

Arcellium's role

Arcellium was instrumental throughout the transformation, from initial discovery and strategic planning through global architecture, data center design, network transformation, infrastructure deployment, migration execution, testing, stabilization, and operational handoff. The company served as the technology transformation partner responsible for turning an extremely complex global infrastructure strategy into an operational reality.

The result was not simply a successful data center exit. It was a fundamental transformation of the organization's global technology infrastructure.
