Geographic Data Placement with S3-Compatible Storage

In today’s digital era, organisations are generating and storing massive amounts of data, much of it unstructured. S3-compatible storage solutions have become the backbone of sustainable cloud storage, providing scalability, reliability, and seamless integration with cloud-native applications.

As sustainability becomes a key IT priority, businesses must look beyond performance and cost savings to evaluate how the physical location of data storage impacts their environmental footprint. Geographic data placement — storing data closer to where it is accessed or processed is emerging as a leading strategy for carbon reduction in data centres and greener cloud operations.

The Hidden Environmental Cost of Distance in Data Storage

When data is stored far from its point of use, it must travel long distances over the Internet backbone infrastructure. This leads to:

• Higher energy consumption during data transmission
• Increased network latency and bandwidth costs
• Greater carbon emissions from long-haul data movement

Research shows that transmitting data over the internet consumes 5–20 kWh per gigabyte, depending on network efficiency and distance. At enterprise scale, where billions of gigabytes are moved annually, the environmental and operational costs multiply significantly.

Centralised cloud storage in remote hyperscale data centres can optimise costs but increases the carbon footprint for global businesses with distributed users or edge devices.

How S3-Compatible Storage Enables Regional Data Placement

Modern S3-compatible storage platforms offer the flexibility to store data in specific geographic regions, whether in public cloud, private cloud, hybrid setups, or edge data centres. This approach allows businesses to:

• Create regional buckets to keep data close to local users
• Deploy on-premises or edge S3 storage near where data is collected and consumed (e.g., in manufacturing, healthcare, or retail)
• Reduce long-distance transfers, improving speed, reliability, and sustainability

By aligning data locality with application proximity, organisations can lower network energy use, reduce carbon emissions, and enhance user experience with faster access speeds.

Sustainability Benefits of Geographic Data Placement

Placing data closer to users delivers measurable sustainability gains:

• Lower transmission energy – Shorter transfer paths mean less electricity is consumed moving data across networks.
• Reduced network equipment power – Fewer hops between routers and switches decrease overall infrastructure energy use.
• Optimised caching and replication – Edge S3 deployments reduce repeated long-haul data transfers.

According to the International Energy Agency (IEA), data centres and transmission networks accounted for 1–1.5% of global electricity use in 2022. Implementing geographic data placement with S3 storage can yield meaningful carbon reductions at scale.

Conclusion

Sustainable Cloud Storage Through Proximity

Geographic data placement is not just about performance — it’s a carbon reduction strategy for sustainable cloud storage. With S3-compatible solutions, organisations can:

• Choose storage regions aligned with user locations
• Minimise energy-intensive data transfers
• Enhance resilience and operational efficiency

In an era where environmental impact is closely measured and regulated, storing data closer to where it’s needed isn’t just efficient — it’s essential for building a sustainable cloud infrastructure.
