In India, that connection is visible in government services such as e-Office and e-Courts, digital payments, identity verification, financial services and enterprise systems. When infrastructure can host and process applications reliably at scale, public agencies and businesses have more room to deploy and expand digital services.
What data centres do for applications
An application needs computing resources to run its software, storage for information and systems to process requests and data. A data centre supplies the underlying facilities and IT infrastructure for those tasks. Cloud services build on that foundation by making computing resources available on demand, so an organisation can provision capacity without treating each application as a separate physical installation.

The Government of India’s Economic Survey 2025–26 describes data centres as supporting application hosting, data processing and storage for government platforms, financial services, enterprises and citizen-centric applications. The practical point is that infrastructure capacity helps determine whether a service can be deployed, store and process the data it needs, and accommodate demand as it grows. The performance of any individual application still depends on its design and operator; national capacity figures do not establish that app’s uptime or speed.

How the connection appears in Indian public services
Government data-centre infrastructure
The National Informatics Centre (NIC) describes its National Data Centres in Delhi, Pune, Hyderabad and Bhubaneswar, alongside 37 smaller data centres in state capitals. NIC says these facilities form the core of government e-governance infrastructure. It identifies e-Office, e-Courts and e-Transport among national projects whose information and communications technology infrastructure has been hosted or enhanced through its services.

NIC also reports more than 370 applications and over 1,080 virtual servers on its mini clouds. These are NIC-reported figures about its services, not a count of every Indian data centre or application. The page also describes co-location and government-cloud services, illustrating the range of infrastructure arrangements behind public-sector applications.
MeghRaj and cloud deployment
MeghRaj, the Government of India’s GI Cloud initiative, provides cloud services for central, state and union-territory departments. A Ministry of Electronics and Information Technology statement published by the Press Information Bureau on December 12, 2025 describes features including elasticity, scalability, pay-per-use metering, self-service provisioning, rapid application deployment and on-demand provisioning. These describe the cloud model and services, not a guarantee that every application hosted there uses every capability.
That December 2025 government statement reported cloud-based applications hosted on MeghRaj for 2,170 Ministries/Departments and 26 empanelled cloud service providers. It said providers were audited by STQC against specified ISO standards. The snapshot demonstrates the initiative’s reach, but does not mean that every ministry application is hosted on MeghRaj. The release also connects government cloud services to e-governance applications such as digital payments, identity verification and consent-based data sharing.
How large is India’s data-centre base?
Capacity statistics are useful context, but they are not a single, directly comparable time series. Sources use different dates and labels, including installed capacity and operational stock. The following figures should be read with their source and reporting period attached.
| Measure | Figure and date | Source and qualification |
|---|---|---|
| Installed capacity | About 1,280 MW as of June 2025 | Government of India, Economic Survey 2025–26, citing industry estimates |
| Data-centre count | Around 130 privately operated and 49 government-agency data centres as of June 2025 | Government of India, Economic Survey 2025–26, citing industry estimates |
| Operational stock and floor area | About 1,530 MW and 23 million square feet as of January–September 2025 | CBRE India Research, 2025 YTD market update |
| Geographic concentration | Nearly 90% of existing capacity in Mumbai, Chennai, Delhi-NCR and Bengaluru in the 2025 snapshot | CBRE India Research, 2025 YTD market update |
| Investment commitments | Nearly USD 94 billion between 2019 and September 2025 | CBRE India Research; commitments are not the same as completed spending or operating capacity |
| Installed capacity | 1.57 GW as of August 2026 | Press Information Bureau, Government of India, September 14, 2026 backgrounder |
| Projected capacity by 2030 | Around 4 GW | Economic Survey 2025–26, citing industry estimates |
| Projected capacity by 2030 | Nearly 8 GW | Press Information Bureau, Government of India, September 14, 2026 backgrounder; a separate projection, not a settled outcome |
| Potential electricity demand | 17 GW by 2031–32 | Central Electricity Authority estimate reported by the Press Information Bureau, Government of India, September 14, 2026; projected demand, not current consumption |
The figures differ in source, date and definition: for example, the Survey’s June 2025 installed-capacity estimate and CBRE’s January–September 2025 operational-stock figure should not be combined as though they measured the same thing. The separate 2030 projections also reflect different snapshots and estimates; neither should be presented as guaranteed capacity. CBRE’s reported investment commitments likewise do not establish that the associated projects have been completed or are operating.

CBRE attributes the concentration of capacity in four metro areas to factors including undersea cable landing stations, fibre connectivity, policy and financial ecosystems. Concentration alone does not prove that an application will be more reliable or faster for every user.
Why capacity matters beyond hosting
Service delivery and growth
For public agencies and businesses, data-centre infrastructure makes it possible to host services and process and store the information they use. Cloud features such as self-service and on-demand provisioning can make it faster to allocate resources and deploy applications. The benefit depends on how the service is implemented; cloud capability does not by itself guarantee a successful rollout.
The Economic Survey links data-centre expansion to digitisation and growing adoption of cloud computing, artificial intelligence, the Internet of Things and 5G. These technologies can add computing and data demands, while the infrastructure serves a broader mix of government, financial, enterprise and citizen-facing applications.
Availability, security and connectivity
Infrastructure size is only one consideration. NIC describes round-the-clock operations and on-site staff, while the MeghRaj statement describes layered security. These are stated operating and service-design approaches, not proof of uninterrupted service or perfect security. An application’s resilience also depends on its architecture, how it handles failures and the operator’s recovery arrangements.
Network connectivity and location matter because applications need users and systems to reach their infrastructure. When comparing infrastructure arrangements, consider where capacity is available, how it connects to users and other systems, whether it can scale, and what security, governance and disaster-recovery measures apply. Government cloud, private infrastructure and commercial cloud services are different arrangements; the available sources do not provide a like-for-like basis for ranking providers.

Energy, cooling and responsible growth
Data centres require dependable electricity and cooling. As capacity grows, power sourcing, cooling efficiency and water use become practical constraints alongside computing demand. The September 2026 Press Information Bureau backgrounder discusses power-demand projections, BIS measures covering power, carbon, cooling and water efficiency, building codes, renewable-energy initiatives and different cooling technologies. Its 17 GW electricity-demand figure is a projection for 2031–32, not a report of present use.
This makes responsible infrastructure planning relevant to application growth: more capacity can support more digital services, but reliable power and efficient, context-appropriate cooling are necessary to operate that capacity. Water and energy considerations should be assessed alongside the application and network requirements rather than treated as separate from digital service planning.
Policy and regulation in context
The September 2026 PIB backgrounder says data centres were included in the Harmonized List of Infrastructure in Union Budget 2022–23. It also describes a tax holiday until 2047 for eligible foreign cloud providers using India-based data-centre infrastructure under the Union Budget 2026–27 framework. These are time-sensitive policy summaries; eligibility and current terms matter if a tax provision is relevant to a specific organisation.
The Telecom Regulatory Authority of India’s data-centres page lists a consultation paper released December 16, 2021, recommendations released November 18, 2022, and a response to a Department of Telecommunications back-reference released November 17, 2025. The index shows continuing regulatory discussion concerning data centres, content delivery networks and interconnect exchanges; it does not, by itself, establish the final status or legal force of every recommendation.
