Why is AWS the Leading Data Centre Company in the World?

Amazon Web Services (AWS) has secured the top position in Data Centre Magazine's Top 100 Data Centre Companies list for 2025 in recognition of the cloud provider's infrastructure scale and pace of innovation across its data centre operations.

AWS operates one of the most extensive cloud and data centre platforms worldwide, supporting millions of customers across industries, from startups to enterprise and public sector organisations. 

In 2025, AWS was ranked number one in Data Centre Magazine's annual Top 100 Data Centre Companies report, due to the company’s global presence, technical leadership and role in providing digital infrastructure to the digital economy. 

"I'm honored and humbled to see AWS recognised as THE #1 company in DataCentre Magazine's Top 100 Data Center Companies!" says Sergio M Loureiro, Vice President of Global Datacenters Operations at AWS.

"This achievement wouldn't be possible without:

• "Our customers who entrust us with their mission-critical workloads
  
• "Our partners & suppliers who strengthen our ecosystem daily
  
• "The communities where we're proud to operate
  
• "Every AWS builder who brings innovation to life."

AWS’s data centres underpin services critical to digital transformation, from compute and storage to AI and machine learning, and enable operations for customers worldwide.

Its operations have expanded through new infrastructure regions, such as the recent launch in New Zealand, which further strengthens both its network capacity and regional focus on renewable energy integration. 

Each expansion aims to serve workload requirements more reliably and with lower latency, while maintaining consistency in security and compliance requirements.

Recent developments: AI, sustainability and capacity expansion

AWS’s ongoing investment in infrastructure has been marked by the introduction of new data centre components designed to support the next generation of AI and high-density computing.

“AWS continues to relentlessly innovate its infrastructure to build the most performant, resilient, secure, and sustainable cloud for customers worldwide,” says Prasad Kalyanaraman, Vice President of Infrastructure Services at AWS. 

Prasad describes the latest data centre redesign as a step towards increased energy efficiency and capacity: “These data centre capabilities represent an important step forward with increased energy efficiency and flexible support for emerging workloads. But what is even more exciting is that they are designed to be modular, so that we are able to retrofit our existing infrastructure for liquid cooling and energy efficiency to power generative AI applications and lower our carbon footprint.”

AWS’s new designs bring together simplified electrical and mechanical systems, modular power distribution and high-density liquid cooling to support the sharply rising compute demands of AI and machine learning. 

These efforts enable AWS to deliver increased compute capacity while reducing overall energy consumption, offering a reported 12% more compute power per site for customer workloads. According to AWS, these changes are expected to lead to a 46% reduction in mechanical energy use during peak cooling and a 35% reduction in the embodied carbon of the concrete used for data centre construction.

A parallel priority for AWS has been the shift toward renewable energy, with the company matching all electricity used in its operations with renewable sources—originally achieving a 2030 target in 2023. 

The current expansion is supported by approximately US$100bn investment across multiple global regions, aimed at building new facilities and refitting existing data centres to minimise environmental impact and maximise operational efficiency.

In June, for instance, AWS unveiled plans to invest US$13bn in Australia to expand its cloud and data centre infrastructure by 2029.

“This is the largest publicly announced global tech investment in the country’s history and reflects the incredible innovation we’re seeing from Australian organisations and their growing demand for advanced cloud and AI capabilities,” said AWS CEO Matt Garman on LinkedIn.

In addition to new regional data centres, AWS announced plans to support the infrastructure expansion by developing green energy capacity in Australia.

“With this commitment, we’re also doubling down on sustainability with three new renewable energy projects to power our operations,” added Garman. “From startups to enterprises to government agencies, we’re excited to support Australia's digital future.” 

Meeting demand responsibly

AWS continues to invest in infrastructure to support its customers’ evolving needs, ensuring that it can offer flexible, scalable environments for next-generation workloads while maintaining security, reliability and sustainability as core principles. 

As the use of generative AI continues to rise and GPU capacity demands increase, AWS data centres are adapting to support increasingly higher power densities and customer needs. Its modular approach allows the company to retrofit existing infrastructure to boost energy efficiency and support for liquid cooling closer to where our users need it most.

AWS also continues to invest in backup power solutions that can run on renewable diesel, reducing greenhouse gas emissions in line with broader Amazon climate commitments. These shifts illustrate the company’s ongoing reevaluation of how its data centres operate and its focus on long-term efficiency.

AWS’s place at the top of Data Centre Magazine’s 2025 Top 100 Data Centre Companies list underscores the company’s influence in powering a digital economy increasingly reliant on AI, cloud and sustainability-centred infrastructure.
