When discussing the world’s largest data centers, Amazon Web Services (AWS) inevitably takes center stage. Launched in 2006 as a sister company to Amazon, AWS was entirely dedicated to cloud computing and has since become one of Amazon’s most successful ventures. With annual revenue exceeding $10 billion – nearly 10% of Amazon’s total revenue – AWS currently dominates more than a third of the global data center market. As the first modern cloud infrastructure provider, AWS’s early entry into the market has been key to its enduring success.
Today, AWS boasts the most comprehensive infrastructure among cloud providers. It runs approximately 33% of daily Internet activity through websites hosted in its data centers. Its market share continues to grow, driven by continuous innovation and an ever-expanding customer base.
AWS customer base
AWS sells computing and processing power services to businesses, enabling them to avoid the costs of owning physical hardware. Her diverse client list includes top names like Airbnb, Netflix, LinkedIn, Facebook, BBC, Reddit, Adobe, Twitter, Twitch, BMW and HTC. Netflix, for example, relies on AWS to host most of its back-end infrastructure.
AWS also supports non-traditional customers such as the UK Department of Justice and NASA’s Jet Propulsion Laboratory. In government, AWS data centers served Obama’s 2012 presidential campaign and the U.S. Navy, which moved 72,000 users to AWS as a step toward cloud-based data and analytics. In 2021, DISH Network announced plans to develop and launch its own 5G network on AWS. Additionally, in October 2021, British intelligence agencies such as GCHQ, MI5 and MI6 contracted AWS to host classified materials.
By lowering barriers to entry for businesses, AWS has fueled the rapid growth of startups and large enterprises alike. However, its role as an important partner to competitors — such as Netflix and Amazon’s Prime Video — has raised a potential conflict of interest.
Advanced fiber optic cable networks
AWS data centers are connected to each other through a robust 100Gb metro fiber network and transoceanic cables spanning the Pacific, Indian, and Atlantic oceans. These urban fiber networks provide high-speed, low-latency broadband connections that outperform traditional infrastructure. AWS has further enhanced its connectivity by partnering with Softbank to launch a 14,000 km trans-Pacific cable, ensuring exceptional performance and reliability for global operations.
Global access to AWS data centers
AWS operates 102 Availability Zones worldwide in 32 regions around the world, and each region often includes multiple data centers. AWS has major availability zones in the US, such as Ohio, Oregon, Virginia, and California, and has dedicated GovCloud data centers for government customers. GovCloud ensures compliance with strict regulations and secures sensitive and non-confidential data.
Outside of the US, AWS services extend to Canada, Brazil, the UK, Sweden, Germany, France, Bahrain, China, Australia, South Korea, Singapore, and more. Amazon continues to build large-scale data centers around the world, comprising tens of thousands of servers. AWS’s largest center is in northern Virginia, an area that is home to more than 100 data centers, though competitors like Google and Microsoft also maintain facilities there.
Despite AWS’s global presence, the company remains tight-lipped about its exact data center locations, often operating through subsidiaries.
In 2018, WikiLeaks published the “Amazon Atlas,” a document from late 2015 that details more than 100 Amazon Web Services (AWS) data centers in 15 cities in nine countries. Notably, the document listed 38 data centers in Northern Virginia alone. The publication included specific addresses and operational details for these facilities.
In the immediate aftermath of this leak, Amazon became even more secretive, referring to its data centers by availability zones rather than specific locations. They avoid sharing exact coordinates and instead focus on regions (e.g., “US East (Virginia)”). Furthermore, Amazon often operates data centers through subsidiaries, making it difficult to trace ownership. For example, properties may be listed under names unrelated to Amazon.

Inside AWS data centers
AWS prioritizes security and resiliency across its data centers. These facilities use a layered approach to protect data and infrastructure:
Ocean layer: Access is strictly monitored, and entry is checked. Employees or contractors must justify their access, subject to regular reviews. Unauthorized access is quickly monitored and remedied through monitoring and intrusion detection.
Infrastructure layer: Backup power systems, HVAC units and fire suppression equipment ensure uninterrupted operations.
Data layer: Multi-factor authentication, automated monitoring, and audits by external auditors secure sensitive data. Auditors evaluate compliance with more than 2,600 standards annually.
AWS chooses data center locations strategically, mitigating risks such as seismic activity and severe weather.
However, the company faces criticism for its lack of transparency regarding environmental sustainability. As demand for data grows, concerns about AWS’ carbon footprint remain unresolved. Amazon’s data centers often rely on fossil fuel-based electricity grids, contributing to a large carbon footprint.
Despite the criticism, the company is showing its commitment to environmental efforts. As of 2023, AWS is already the world’s largest buyer of renewable energy, with 379 wind and solar projects. AWS infrastructure is 3.6 times more energy efficient than typical enterprise data centers, according to 451 Research. This includes innovations such as liquid cooling and energy-efficient processors.
However, AWS’s cooling systems rely heavily on water. While it has pledged to be water positive by 2030, how to achieve this remains unclear. Critics highlight that AWS needs to provide more transparency about emissions outside its direct operations, such as those from its supply chains.
