Sustainable Cloud

Cloud computing requires significant energy, cooling and physical infrastructure. Sustainable cloud computing focuses on reducing that environmental impact through greater energy efficiency, innovative cooling technologies, efficient use of hardware and more responsible data-centre design.

Explore the technologies, measurements and approaches shaping more sustainable cloud infrastructure.

Essential Reading

Explore the technologies and principles behind sustainable cloud computing, from liquid immersion cooling and data-centre efficiency to the metrics used to measure energy and water consumption.

How Sustainable Cloud Infrastructure Works

Sustainable cloud infrastructure is not defined by a single technology. Efficiency comes from combining computing, cooling, data-centre design and resource management to reduce the infrastructure required to deliver digital services.

Efficient Computing

Learn how virtualisation and higher infrastructure utilisation can reduce the amount of physical hardware required to support computing workloads.

Efficient Cooling

Explore how modern cooling technologies can reduce the energy and resources traditionally required to remove heat from data-centre infrastructure.

Liquid Immersion Cooling

Discover how immersing IT equipment directly in dielectric fluid provides an alternative to traditional air-based server cooling.

High-Density Computing

Understand how efficient thermal management can support greater computing density, including demanding HPC and AI workloads.

Understanding Data-Centre Efficiency

Understanding sustainability requires more than looking at electricity consumption alone. Data-centre efficiency can be assessed across energy use, cooling, water consumption, hardware utilisation and the resources required to operate IT infrastructure.

Power Usage Effectiveness (PUE)

Understand what PUE measures, how it is calculated and what the metric can—and cannot—tell us about data-centre efficiency.

Water Usage Effectiveness (WUE)

Learn how WUE measures the water consumed by data-centre operations and why water efficiency is becoming increasingly important.

Cooling Efficiency

Explore why cooling represents an important component of data-centre resource consumption and how different cooling architectures affect efficiency.

Server Utilisation

Understand why improving utilisation can allow organisations to deliver more computing capacity from the same physical infrastructure.

Sustainable Cloud by Business Need

Reduce Energy Consumption

Explore how efficient infrastructure and cooling technologies can reduce the energy required to operate cloud computing environments.

Reduce Water Consumption

Understand the relationship between data-centre cooling and water use, and how alternative cooling technologies can reduce dependence on water-intensive systems.

Support ESG Objectives

Learn how cloud infrastructure decisions can contribute to broader organisational environmental and sustainability strategies.

Modernise Legacy Infrastructure

Explore how consolidation, virtualisation and efficient cloud infrastructure can reduce reliance on underutilised physical IT systems.

Liquid Immersion Cooling in Practice

Liquid immersion cooling takes a fundamentally different approach to managing server heat. Instead of using fans and large volumes of conditioned air, computing hardware is immersed in a non-conductive fluid that transfers heat directly away from components.
