As data grows across businesses and society, the infrastructure used to store and protect it is increasingly important. Artificial intelligence (AI), the Internet of Things (IoT), digital payments and connected industries all depend on fast, reliable access to information. Dr Chandan Dash highlights how cloud storage, data centres and edge computing are working together to support this transformation.
Understanding the Three Layers of Digital Infrastructure
Traditional data centres are purpose-built facilities housing servers, storage systems, networking equipment and power and cooling infrastructure. They provide the computing capacity needed for enterprise applications, large databases, data retention and analytics.
Cloud computing makes these resources available over the internet. Rather than owning all the infrastructure, organisations can access storage and computing services from providers such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud. Cloud environments may be public, private, hybrid or multicloud, depending on security, compliance, cost and operational needs.
Edge computing complements centralised infrastructure by processing data closer to where it is generated. Local gateways, devices and smaller facilities can analyse information near smart factories, connected vehicles, hospitals or IoT sensors. This reduces delays for time-sensitive decisions, while central platforms support coordination, analytics and backup.
India’s Expanding Data Centre Ecosystem
India’s data centre sector is growing with digital services, cloud adoption, AI workloads and demand for local infrastructure. The Press Information Bureau reported that installed data-centre power capacity reached around 1.57 GW in August 2026, compared with approximately 375 MW in 2020. This highlights the growing need for dependable infrastructure.
Major operators and infrastructure providers in India include ST Telemedia Global Data Centres India (STT GDC India), Yotta Data Services, CtrlS Datacenters, NTT Global Data Centers, Nxtra by Airtel, Sify Technologies, AdaniConneX, Equinix, Digital Connexion and Iron Mountain. They provide colocation, power, cooling and connectivity to enterprises and cloud customers. STT GDC India, for example, reports 34 data centres across 10 cities and 613 MW of IT load capacity. Capacity figures should be compared carefully, as providers may report operational, designed, under-construction or planned capacity differently.
Cloud Storage Versus Local Storage
Cloud storage keeps files on remote infrastructure managed by a service provider. It enables access across devices, easy sharing, collaboration, synchronisation and off-site backup. Drawbacks can include recurring fees, internet dependence, transfer costs and privacy or compliance concerns.
Local storage keeps information on hardware controlled by the user or organisation, such as SSDs, hard drives, USB devices or network-attached storage (NAS). It offers fast offline access and direct control. However, devices may be damaged, stolen or fail, causing data loss if backups are not maintained.
Neither option is best for every situation. A hybrid strategy can keep frequently used or large files on local systems while using encrypted cloud storage for remote access, collaboration and off-site recovery. Businesses should keep separate backups and test recovery.
A Fast-Growing Global Market
Market forecasts underline the scale of investment in cloud infrastructure. Fortune Business Insights estimates that the global cloud storage market was valued at USD 161.28 billion in 2025 and could rise from USD 197.8 billion in 2026 to USD 809.99 billion by 2034, representing a compound annual growth rate of 19.3%. These are estimates, not guaranteed outcomes, and vary by research method.
AI workloads, rising data volumes, hybrid-cloud adoption, digital transformation and connected devices are driving demand. North America currently accounts for the largest regional share, while Asia-Pacific economies, including India, are investing in infrastructure to serve expanding digital activity. Leading cloud ecosystems include AWS, Azure and Google Cloud.
Challenges and the Road Ahead
Expansion brings challenges: reliable electricity, cooling, skilled professionals and robust physical and cyber security are essential. Water use, emissions, compliance, data sovereignty, resilience and construction costs also matter. Edge systems also require secure monitoring and updates.
The future is unlikely to be a choice between cloud, local storage or edge computing. Organisations will combine them according to workload, latency, cost, security and compliance needs. As Dr Chandan Dash notes, the strength of the digital economy will depend not only on how much data can be stored, but on how efficiently, responsibly and securely it can be accessed and used.
