Tata & AWS Build AI-ready Long-haul Network Across India
Tata Communications is building a new national network in partnership with Amazon Web Services (AWS), aimed at boosting AI and machine learning (ML) capabilities across India.
Connecting Mumbai, Hyderabad and Chennai, this infrastructure will be one of the most extensive long-distance telecoms networks deployed in the country to date.
Designed to handle the scale and speed required for Gen AI, 5G and high-performance computing (HPC), the network links AWS’ key Indian data centre regions. This provides the foundation for businesses to adopt advanced cloud technologies with improved security, throughput and latency.
A national backbone for AI and cloud
The new deployment connects three AWS infrastructure hubs via high-bandwidth, ultra-low latency fibre, forming the foundation for a large-scale AI and cloud network across India.
These routes form what Tata Communications describes as its largest national long-distance network programme by bandwidth and reach.
By using its existing communications infrastructure and advanced network technology, Tata aims to provide pathways capable of handling increasingly data-heavy AI applications.
This includes workloads that rely on massive compute power, such as Gen AI, which generates text, images or other content in response to prompts, and HPC tasks across sectors like finance and healthcare.
“This association marks our largest ever National Long-Distance program and showcases Tata Communications’ unparalleled capability to support large-capacity, complex projects requiring scaled network solutions,” says Genius Wong, EVP of Core and Next-Gen Connectivity Services and Chief Technology Officer at Tata Communications.
“AI is transforming industries globally and our collaboration with AWS positions us at the forefront of this revolution in India. Together, we’re enabling a network that not only meets the current demands but anticipates the needs of tomorrow.
“By building a tailored network solution we're ushering in an AI era in India, reinforcing our position as the long-term partner of choice for global technology leaders.”
Designed to meet intensive data demands
The partnership supports AWS' Indian operations, where the cloud provider already operates primary data centre regions in Mumbai and Hyderabad, and maintains additional AWS Direct Connect and Edge Network capabilities in Chennai. These enable direct private connectivity to AWS services and provide local points of presence for data processing.
The long-haul network between these cities is purpose-built to reduce latency and support seamless data transfer essential for AI and ML tasks.
As businesses shift towards compute-intensive use cases, performance and bandwidth become key requirements. This initiative is expected to provide the capacity to meet those demands while staying aligned with regulatory and data protection expectations.
AWS’ custom-designed network technologies form part of this architecture, offering improved performance, availability and security across the entire fabric.
This ensures that workloads — from real-time AI inference to large-scale model training — can be processed efficiently and within Indian borders, a crucial factor for data compliance and trust in cloud systems.
"We are excited to work with Tata Communications to establish an advanced in-country network in India,” says Jesse Dougherty, Vice President for Network Edge Services at Amazon Web Services.
“The infrastructure is designed to support the most data intensive workloads, like 5G, Gen AI and high performance computing. This collaboration with Tata Communications will further enable our customers in India to innovate at scale with cloud and Gen AI and drive growth in India’s rapidly expanding digital economy.”
Built to support growth and innovation
The network enables Indian enterprises across sectors — from education and retail to finance and healthcare — to develop and run AI systems at scale. Tata Communications expects this to unlock new business models and drive national adoption of digital tools.
Faster connectivity between major hubs also improves performance for cloud-based applications.
Lower latency and higher throughput mean AI and HPC workloads can be deployed and scaled more efficiently, cutting both time and cost for businesses aiming to integrate Gen AI.
The infrastructure also supports the evolution of 5G by providing backhaul suitable for high-speed, data-heavy applications such as streaming, smart cities and IoT. These developments reflect a broader pattern within India and other emerging markets: cloud and AI-ready networks are becoming central to digital transformation strategies.
Tata Communications’ role in deploying and managing the infrastructure, paired with AWS’ global cloud services, provides India with a telecoms foundation ready to meet the increasing demand for AI-based solutions.
For telecoms leaders, it highlights how cross-sector partnerships are reshaping network expectations across the region.
As Genius Wong concludes, “By building a tailored network solution we're ushering in an AI era in India, reinforcing our position as the long-term partner of choice for global technology leaders.”
