The Challenges
The customer had deployed application environments on Microsoft Azure in the US West (Seattle) region, with India-based teams accessing these environments remotely over public internet connectivity. This resulted in:
-
Unstable performance and high latency, impacting user productivity
-
Severe application lag, including noticeable delays in routine tasks within virtual desktops
-
Inconsistent access experience, affecting day-to-day operations
-
Compliance constraints, preventing data from being moved outside the US
To address these challenges, the organization needed a connectivity approach that could:
-
Deliver secure and compliant access to US-hosted workloads
-
Provide consistent, predictable application performance for offshore teams
-
Avoid penalties from end clients tied to poor connectivity and reduced productivit
The Solution
Tata Communications deployed IZO™+ Multi Cloud Connect (MCC Direct) to provide dedicated, enterprise-grade connectivity between the customer's India operations and their Azure environment in the US. Key capabilities, that addressed the requirements listed above, included:
-
Private MPLS connectivity: Deployed at the customer's Bangalore office to eliminate reliance on the public internet
-
Global Network Integration: Extension of this private network to Azure US West (Seattle) via Tata Communications' global backbone
-
Production-grade scalability: Upgrade from an initial proof-of-concept (POC) to a 500 Mbps production deployment
-
High availability design: Implementation of an active-active dual-link architecture for resilience and continuity
-
Committed reliability: Delivery of a 99.99% SLA for consistent, predictable performance
The customer validated performance improvements through a limited pilot before committing to full-scale deployment.
The Result
With IZO™+ Multi Cloud Connect, the organization achieved:
-
Improved latency and stability: Eliminating performance variability associated with internet-based access
-
Seamless application access: Reliable connectivity to Azure-hosted applications for India-based team
-
Enhanced productivity: No noticeable application lag in day-to-day operations
-
Enterprise-grade reliability: SLA-backed connectivity supporting mission-critical workloads
-
Sustained regulatory compliance: All data securely retained within the US, meeting HIPAA requirements
-
Deterministic, SLA-backed connectivity: A shift away from unpredictable internet performance to a scalable architecture built for growth
Post-deployment, the solution has operated smoothly, with no reported issues over several months of usage.
What we learnt
For a global healthcare provider balancing HIPAA compliance with offshore delivery, Tata Communications enabled a shift from unpredictable, internet-based access to a secure, deterministic connectivity model. IZO™+ Multi Cloud Connect gives regulated enterprises - across healthcare, GCCs, BPO/KPO, and other cross-border delivery models - a repeatable path to compliant, low-latency access to US-hosted cloud applications, without compromising on performance or productivity.
As organisations increasingly centralize global operations through Global Capability Centres (GCCs) and offshore delivery teams, many are required to support customers in highly regulated markets while maintaining strict data sovereignty and compliance requirements. Industries such as healthcare, financial services, and public sector services often mandate that sensitive data remain within specific geographic boundaries, requiring workloads and applications to be hosted in-country or within approved regions.
For these organizations, employees and contractors located overseas must securely access applications and data without violating regulatory requirements such as HIPAA and GDPR. Relying on public internet connectivity to access cloud-hosted environments can introduce unpredictable latency, inconsistent user experiences, and operational inefficiencies that directly impact productivity. The issues don't end with performance impact alone — they also translate into penalties imposed on GCCs by their primary end-clients over connectivity and productivity gaps.
Tata Communications recently served one such requirement for a global healthcare solutions provider serving US-based clients, with a significant delivery presence in India. Due to regulatory requirements such as HIPAA compliance, all application workloads and sensitive data had to remain hosted within the United States.
