SUSTAINABLE CLOUD & AI

Use compute. Store data. Waste less carbon.

Cloud and AI have a real environmental footprint. The useful question is not whether data centres use energy — they do — but whether your architecture is using the cleanest practical infrastructure, the right amount of compute and the right amount of data.

No greenwashing. We distinguish operational carbon from embodied carbon, renewable-energy claims from 24/7 carbon-free matching, and efficiency gains from genuine emissions reduction. “Zero carbon” is only used where the evidence actually supports it.
ARCHITECTURE FIRST

Make sustainability an infrastructure requirement.

We can design or review cloud, AI and data platforms with carbon, power, water and hardware utilisation treated as architecture constraints alongside cost, resilience, security and performance.

LOCATION

Lower-carbon compute placement

Choose cloud regions, sovereign cloud or colocation facilities where electricity supply and operating model can materially reduce operational emissions.

  • Regional grid carbon intensity
  • 24/7 carbon-free-energy evidence where available
  • Latency and data-residency trade-offs
  • Carbon-aware batch scheduling
COLOCATION

Sustainable data-centre architecture

For workloads that do not need hyperscale cloud, we can assess efficient colocation and private-cloud options with strong sustainability evidence.

  • PUE and cooling design
  • Water consumption and WUE
  • Renewable or low-carbon power sourcing
  • Heat reuse and facility transparency
AI & HPC

Carbon-aware AI compute

AI sustainability is largely an engineering problem: model choice, accelerator utilisation, workload timing and data movement all matter.

  • Right-size GPU and accelerator choice
  • Batch work when/where power is cleaner
  • Increase accelerator utilisation
  • Avoid unnecessary retraining and inference
DATA

Store less. Move less. Keep it intelligently.

Data that is duplicated, retained forever or held on inappropriate storage consumes energy and money for no useful business outcome.

  • Lifecycle and retention policies
  • Cold/archive storage tiers
  • Deduplication and compression
  • Reduce unnecessary replication and transfer
OUR POSITION

Efficient technology is usually better technology.

There is often no conflict between sustainability and good architecture. Fewer idle servers, smaller datasets, better utilisation, sensible lifecycle policies and efficient facilities frequently reduce both carbon and cost.

Measure before claimingPrefer auditable power, carbon and facility data over vague renewable-energy marketing.
Optimise the workload firstThe cleanest kWh is still the one the workload never needed to consume.
Use the right platformHyperscale cloud, sustainable colocation and private infrastructure each have valid use cases.
Include embodied impactHardware manufacturing and replacement cycles matter as well as electricity during operation.
WHAT WE WOULD ASSESS

Evidence, not eco-labels.

A sustainability review can turn broad concerns into architecture decisions and measurable criteria for suppliers.

EnergyGrid mix, carbon intensity, CFE matching and workload timing.
FacilityPUE, cooling, WUE, heat reuse and utilisation.
ComputeCPU/GPU utilisation, right-sizing and accelerator efficiency.
DataVolume, lifecycle, replication, transfer and retention.

Want sustainability designed into the architecture?

CloudFIXER can help define the requirements, compare cloud and colocation options, and produce an architecture that balances carbon, cost, resilience, security and performance.

WATER & COOLING

Cooling computers does not have to consume water.

Liquid cooling and water consumption are not the same thing. In a genuinely closed-loop system the coolant is recirculated. The key design question is how heat is rejected at facility level: a closed IT loop can still feed an evaporative tower, so CloudFIXER would preferentially assess facilities using closed-loop cooling with non-evaporative or dry heat rejection where practical.

Closed-loop designCoolant is reused rather than continually replaced.
Non-evaporative heat rejectionPrefer dry coolers or equivalent designs that do not depend on routine evaporation.
Measured WUEAsk for actual Water Usage Effectiveness, not simply a marketing label.
Water source & dischargeCheck potable vs reclaimed water, top-up, blowdown and wastewater requirements.
