The data centre industry continues to evolve as digital demands increase worldwide. As a result, businesses are looking to the leading technology providers that can support them in their innovation.

With this in mind, Data Centre Magazine spotlights some of the leading technology companies that support the industry with mission-critical technologies. The companies featured on this list hold very strong influence in the data centre sector, with the ranking based on market cap and their technology-led offerings.

10. Nvidia

HQ: Santa Clara, California, USA

CEO: Jensen Huang

FY Revenue: US$60.9bn (FY 2024)

Once known primarily for gaming hardware, Nvidia now powers AI and high-performance computing (HPC) in data centres worldwide. The company envisions traditional data centres transforming into 'AI factories' - a vision driving its strategy. GPUs from NVIDIA train complex AI models and run scientific simulations that were previously impossible.

Energy efficiency remains a priority as AI workloads multiply, with the company continuing to expand beyond processors. Specifically, its BlueField platform signals broader aspirations to provide end-to-end infrastructure for next-generation computing needs.

9. Schneider Electric

HQ: Rueil-Malmaison, France

CEO: Olivier Blum

FY Revenue: €38 billion / US$41.72bn (FY 2024)

Power distribution systems, cooling technologies and management software form the backbone of Schneider Electric's offerings. Crucially, the company is a leader in data centre infrastructure management (DCIM) tools, as it seeks to monitor physical systems across complex environments. Schneider Electric has successfully been able to link business strategy to sustainability targets, helping operators improve Power Usage Effectiveness (PUE) metrics to meet strict environmental regulations.

When data centres stay online and operate efficiently, Schneider's systems are often working behind the scenes. The company tackles the fundamental challenge of keeping facilities running without interruption.

8. Broadcom

7. Oracle

HQ: Austin, Texas, USA

CEO: Safra A. Catz

FY Revenue: US$49.9bn (FY 2023)

Following its enterprise software success, Oracle now operates data centres worldwide supporting Oracle Cloud Infrastructure (OCI). Hybrid and distributed cloud solutions form the core of Oracle's strategy, allowing enterprises to maintain control while modernising IT infrastructure.

In March 2025,Oracle announced a US$5bn investment plan over the next five years to expand its cloud infrastructure across the UK.

Security and compliance standards also remain central to the company's approach, addressing regulatory requirements that vary across jurisdictions. Likewise, by 2050, Oracle aims to achieve net-zero emissions, with a goal of 100% renewable energy usage.

6. Digital Realty

HQ: Austin, Texas, USA

CEO: Andrew Power

FY Revenue: US$5.55bn (FY 2024)

As a leading data centre organisation, Digital Realty manages over 300 carrier-neutral facilities across more than 50 metropolitan areas. Anticipating that AI will only continue to driveunprecedented demand for data centre capacity, requiring substantial investment in high-density computing infrastructure.

Digital Realty is also prioritising certifications and resource conservationinitiatives have become standard practice for the company. Direct, low-latency connections to major cloud providers enable clients to implement hybrid strategies, which in turn creates flexibility for organisations balancing on-premises needs with cloud expansion plans.

5. Equinix

HQ: Redwood City, California, USA

CEO: Adaire Fox-Martin

FY Revenue: US$8.748bn (FY 2024)

'International Business Exchange' data centres form the foundation of Equinix's global infrastructure network. The organisation operates more than 260 of these facilities worldwide, creating an interconnection ecosystem where businesses exchange data with minimal latency and reduce performance bottlenecks for mission-critical applications requiring instant response times.

As a key player in the data centre industry, Equinix has responded to continued shifts in the market by expanding its support for private AI infrastructure deployment. This move addresses growing client demand for computing resources that balance performance with control over sensitive data.

4. Cisco

HQ: San Jose, California, USA

CEO: Chuck Robbins

FY Revenue: $53.8 billion (FY 2024)

Cisco critical infrastructure solutions provide reliable, automated and secure networking for mission-critical data across the customer's access, edge, core, data centre and Internet connections. Data centre uptime depends on Cisco switches and routers that form communication pathways between computing resources.

Acquiring Splunk in 2024 ultimately broadened Cisco's ability to monitor complex environments and identify security threats before they impact operations. The deal strengthened observability capabilities at a time when infrastructure complexity only continues to increase.This shift mirrors wider industry movement toward practices that reduce energy consumption while maintaining performance standards.

3. Google Cloud Platform (GCP)

HQ: Mountain View, California, USA

CEO: Thomas Kurian

FY Revenue: US$43.2bn (FY 2024)

Google Cloud builds world-class data centres that provide essential infrastructure for businesses, governments and individuals to connect with each other. With this in mind, specialised infrastructure for AI and analytics has become a strong marker of their brand, as the tech giant seeks to harness its workloads to reshape the requirements of data centres design.

Water resource management features are also prominent in the company's facility planning, with Google prioritising community engagement to create local economic growth around its data centre locations. At its heart, Google Cloud is eager to prioritise a sustainable future for the data centre industry, particularly in the wake of its emissions rising last year.

2. Microsoft Azure

HQ: Redmond, Washington, USA

CEO: Satya Nadella

FY Revenue: US$261.8bn (for twelve months ending December 2024, Intelligent Cloud segment)

Hybrid cloud solutions have helped define Microsoft Azure's approach to data centre services. Significantly, its zero-water cooling designs - that it plans to implement across its new data centre developments - mark a fundamental shift in its approach to thermal management for high-density AI workloads.

Microsoft is also aiming to become carbon negative by 2030, setting ambitious environmental targets that include 100% renewable energy by 2025. These goals align with increasing focus on ESG factors throughout the sector. Likewise, Azure bridges on-premises infrastructure with public cloud environments in a way that appeals to organisations maintaining both.

1. Amazon Web Services (AWS)

HQ: Seattle, Washington, USA

CEO: Matt Garman

FY Revenue: US$107.6bn (FY 2024)

AWS has more than 200 offerings that span from basic compute and storage to machine learning capabilities that power innovation across multiple industries. For data centres specifically, AWS is leading by design with its cloud services making it one of the largest consumers of Internet data centre capacity.

Continuously improving the design and systems of its data centres, AWS hopes to continue protecting its facilities from man-made and natural risks. It implements controls, builds automated systems and undergoes third-party audits to confirm security and compliance. As a result, the most highly-regulated organisations in the world trust AWS with their data.

The company is targeting ratings of 1.08 for new facilities, which is significantly below the industry average. A move like this demonstrates a clear focus for AWS on operational efficiency in a sector where energy costs impact competitiveness.
