E02 How Data Centres Interact with the World

ByMalaysia Data Centre Observatory

Key Takeaways

  • A data centre transforms physical resources such as electricity, water, land and connectivity into digital services used around the world.
  • Although its products are digital, a data centre is deeply connected to physical communities, utility networks, infrastructure systems and the natural environment.
  • Every major input reflects a balance between reliability, performance, sustainability, economics and public expectations rather than engineering considerations alone.
  • Understanding these resource flows provides a more balanced foundation for discussions about both the benefits and impacts of data centre development.

The Digital World Has Physical Neighbours

For most people, the digital world feels almost weightless.

A video streams instantly. A bank transfer completes in seconds. Artificial intelligence answers complex questions within moments. Behind the screen, everything appears to happen effortlessly, as though digital services exist somewhere beyond the physical world.

Yet nothing could be further from reality.

Every search engine query, online purchase, video conference, medical record, financial transaction and AI conversation ultimately depends upon physical infrastructure. Data travels through fibre-optic cables, is processed by powerful computers, cooled by sophisticated engineering systems, protected by multiple layers of security and supplied continuously with electricity. The digital economy, despite its virtual appearance, is built upon an extensive network of very real facilities.

At the centre of this network sits the modern data centre.

Malaysia is becoming an increasingly important part of that global infrastructure. Large-scale data centres are being developed across Johor, the Klang Valley and other strategic locations, forming part of a regional digital ecosystem that serves not only Malaysian users but businesses, governments and individuals throughout Southeast Asia and, increasingly, the wider world. A cloud application used in Singapore, an AI model serving customers across Asia-Pacific, or an international financial transaction may all be processed by computing infrastructure physically located in Malaysia.

This presents both an opportunity and a responsibility.

Malaysia can take pride in contributing to the infrastructure that supports the world’s growing digital and AI-driven economy. At the same time, these facilities become our physical neighbours. They consume local resources, connect to local infrastructure and interact with surrounding communities. Like airports, ports, highways or power stations, they deliver benefits that extend far beyond their immediate surroundings while also creating local impacts that must be carefully managed.

Understanding how data centres interact with the world is therefore essential. It allows discussions to move beyond simple questions of whether data centres are “good” or “bad”, towards a more informed appreciation of how they create value, why they require significant infrastructure, and how different interests can be balanced for the benefit of all stakeholders.

MDCO Insight: Data centres may serve global digital needs, but they always operate within local communities, making their success dependent on both international connectivity and local acceptance.

Every Data Centre Is a Transformation System

One useful way to understand a data centre is to think of it not simply as a building, but as a transformation system.

Every day, enormous quantities of resources flow into the facility. Electricity powers computing equipment. Water may support cooling systems. Fibre-optic cables carry digital information from users around the world. Engineers, operators and maintenance personnel keep systems functioning. Land provides space for infrastructure. Capital finances construction and continual upgrades. Equipment and spare parts arrive through global supply chains.

Inside the data centre, these diverse inputs are brought together through thousands of interconnected systems. Electrical infrastructure distributes power. Cooling systems remove heat. Network equipment routes information. Security systems protect physical and digital assets. Automation platforms continuously monitor and optimise operations. At the heart of the facility, servers perform the computing tasks that underpin modern digital life.

The result is transformed into something of immense value but largely invisible: computing services.

Cloud storage, online banking, e-commerce platforms, streaming services, government digital services, scientific research, enterprise software and artificial intelligence all depend upon this transformation process.

Yet the process does not end there.

Like every large infrastructure system, a data centre also produces physical outputs. Most of the electricity consumed eventually leaves the building as heat. Cooling equipment and transformers generate noise. Backup generators may produce emissions during testing or emergency operation. Water used for cooling may evaporate or require controlled discharge. Construction and operation create employment, investment and economic activity, while also increasing demands on supporting infrastructure.

In other words, a data centre continuously exchanges resources, services and impacts with the world around it. Digital services represent only one part of a much larger system of physical flows.

Viewing a data centre through this systems perspective helps explain why discussions surrounding these facilities often become complex. Questions about electricity, water, environmental performance, planning approvals, investment or community concerns are not isolated issues. They are different perspectives on the same interconnected transformation process.

MDCO Insight: A data centre is best understood not as a standalone building, but as a system that continuously transforms physical resources into digital value while interacting with society in multiple ways.

Inputs: What a Data Centre Receives from the World

Every digital service begins with something physical.

Although attention often focuses on servers and software, the ability of a data centre to operate depends upon a steady flow of resources from outside the facility. These inputs originate from utility providers, governments, investors, equipment manufacturers, telecommunications operators, construction companies, regulators and the communities in which data centres are located.

Each input serves a different purpose, yet all are interconnected.

Electricity: The Foundation of Digital Services

Electricity is the most fundamental input to any data centre. Without it, every server, storage device, network switch, cooling unit, security system and monitoring platform would cease operating almost instantly.

Modern hyperscale facilities may consume tens or even hundreds of megawatts of continuous electrical power. This level of demand is comparable to that of a medium-sized town or major industrial estate, explaining why many facilities require direct connections to high-voltage transmission networks through dedicated 132kV or 275kV substations.

However, providing sufficient electricity is only part of the challenge.

Digital services increasingly underpin banking systems, hospitals, telecommunications, manufacturing, logistics, government operations and artificial intelligence. Society expects these services to remain available at all times. As a result, customers demand extremely high reliability, encouraging developers to invest heavily in redundant electrical systems, uninterruptible power supplies and standby generators.

This illustrates an important principle that appears repeatedly throughout the data centre industry. Infrastructure is rarely designed solely because engineers prefer complexity. More often, it reflects society’s expectation that essential digital services should never stop.

Different stakeholders naturally view electricity from different perspectives. Customers prioritise reliability. Utilities focus on grid stability. Investors consider operating costs. Governments examine national energy security and economic competitiveness. Communities may be concerned about visual impacts, noise from substations or future electricity availability. Environmental organisations may focus on energy efficiency and carbon emissions.

All of these perspectives influence how electrical infrastructure is ultimately designed.

Water: Cooling the Digital Economy

If electricity powers computing, cooling enables it.

Almost every unit of electricity consumed by computing equipment eventually becomes heat. Unless this heat is removed, servers quickly exceed their safe operating temperatures and digital services become unreliable.

Many data centres therefore use water, either directly or indirectly, to support cooling systems. Depending on the chosen technology, water may circulate through cooling towers, chillers or heat exchange equipment before dissipating heat into the surrounding environment. Water is also required for fire protection systems, equipment maintenance and normal building services.

The relationship between water and sustainability, however, is far from straightforward.

Cooling technologies that minimise water consumption may require additional electricity. Others reduce energy demand but increase water use. Designers must therefore balance local climate, water availability, electricity prices, environmental objectives and operational reliability rather than attempting to optimise a single performance indicator.

This explains why seemingly simple questions about water use rarely have simple answers. The most appropriate solution in one location may not be the most appropriate elsewhere.

Increasingly, the industry is also exploring alternative cooling technologies, including liquid cooling for AI workloads, closed-loop cooling systems and greater use of recycled or non-potable water where suitable. These innovations reflect not only technological progress but also growing expectations from governments, customers and communities regarding responsible resource management.

Connectivity: The Digital Lifeline

Unlike electricity or water, connectivity functions as both an input and an output.

Every search request, video stream, online purchase or AI prompt enters the data centre through fibre-optic networks. After being processed, the resulting information immediately leaves the facility along the same interconnected global telecommunications infrastructure.

In many respects, fibre-optic cables perform a role similar to highways or railways in the physical economy. Instead of transporting goods, they transport information at the speed of light, linking users to computing resources across countries and continents.

This explains why data centres are frequently located near major fibre routes, internet exchanges and submarine cable landing stations. Reliable connectivity is as important to digital infrastructure as reliable roads are to manufacturing or logistics.

As digital services become increasingly international, connectivity also acquires strategic significance. High-capacity telecommunications infrastructure enhances economic competitiveness, supports cross-border investment and enables Malaysia to participate more fully in the regional and global digital economy.

Land, Materials, People and Capital

While electricity and water often receive the greatest public attention, many other inputs are equally essential.

Every data centre begins with land. The location determines available utilities, transportation links, environmental conditions and proximity to surrounding communities. Construction requires substantial quantities of steel, concrete, copper, aluminium, specialised mechanical and electrical equipment, as well as sophisticated computing hardware sourced through global supply chains.

Equally important are the people who design, build and operate these facilities. Engineers, architects, contractors, regulators, utility providers, maintenance specialists, security personnel and emergency responders all contribute to different stages of the data centre lifecycle. Their expertise represents an input every bit as important as physical infrastructure.

Behind all these resources lies investment capital. Developing a modern hyperscale campus requires significant long-term financial commitment, often involving international investors, technology companies, financial institutions and government investment promotion agencies. These investors expect projects to deliver reliable digital infrastructure while also achieving commercial sustainability over many years.

Taken together, these inputs illustrate that a data centre is not simply a collection of servers. It is the meeting point of multiple infrastructure systems, industries and institutions working together to support the digital services on which modern society increasingly depends.

MDCO Insight: Every resource entering a data centre reflects decisions made by many different stakeholders, each balancing technical performance, economic value, sustainability and public expectations.

Transformation: How Infrastructure Converts Resources into Computing Services

Receiving electricity, water, connectivity and other resources is only the beginning of a data centre’s role. The true purpose of the facility is to transform these inputs into reliable digital services that users can access anywhere and at any time.

This transformation is made possible by a network of highly specialised infrastructure systems working together continuously.

Electrical systems distribute power from the transmission grid through transformers, switchgear, uninterruptible power supplies and standby generators before it reaches the servers. Cooling systems remove the heat generated by computing equipment to keep it operating within safe limits. Fibre-optic networks carry information into and out of the facility, while security systems protect both physical infrastructure and digital assets. Fire protection systems safeguard equipment and personnel, while building management and automation systems continuously monitor thousands of operating conditions to optimise performance and identify potential faults before they become failures.

None of these systems exists in isolation. Each reflects decades of technological development and the accumulated experience of governments, regulators, equipment manufacturers, operators, customers and international standards organisations. Their combined objective is remarkably simple: to ensure that digital services remain available whenever society depends upon them.

The design of these systems is therefore not determined solely by engineering considerations. It is also shaped by expectations. A hospital expects uninterrupted access to patient records. A bank expects financial transactions to remain available every second of the day. Cloud customers expect their applications to continue operating despite equipment failures, utility interruptions or extreme weather events. These expectations ultimately influence decisions about redundancy, resilience, security and operational procedures throughout the facility.

Yet every improvement carries consequences. Higher reliability often requires duplicate equipment. Greater resilience demands additional electrical infrastructure, cooling capacity and backup systems. Enhanced cybersecurity introduces more sophisticated monitoring and access controls. Each decision improves one objective while increasing costs, complexity or resource requirements elsewhere.

The modern data centre is therefore not simply an engineering achievement. It is the physical embodiment of society’s collective expectations regarding reliability, security, performance and trust in the digital economy.

MDCO Insight: Every major infrastructure system inside a data centre exists because society values continuous digital services enough to justify the additional investment and resources required to achieve them.

Outputs: What a Data Centre Gives Back

The most obvious output of a data centre is digital.

Every second, millions of users access cloud computing, artificial intelligence, financial systems, communications platforms, government services, scientific research and countless other applications supported by computing infrastructure housed within data centres. These services increasingly underpin economic productivity, innovation and everyday life.

However, the benefits extend well beyond computing itself.

Large-scale data centre investments stimulate demand for construction, engineering, manufacturing, utilities, telecommunications and professional services. They encourage improvements to electricity networks, fibre infrastructure and transport systems that may also benefit surrounding industries. They attract investment, create employment opportunities and strengthen Malaysia’s position within regional and global digital supply chains.

At the same time, every physical process produces physical outputs.

Almost all of the electricity entering a data centre eventually leaves as heat. Cooling equipment, transformers and standby generators generate noise. Water used in cooling systems may evaporate or require controlled discharge. Construction activities consume materials and produce waste. Backup generators may emit pollutants during routine testing or emergency operation. Large facilities increase demand for electricity transmission, water infrastructure and supporting public services.

Not all of these outputs should automatically be viewed as negative. Heat, for example, is not pollution in itself but an unavoidable consequence of converting electrical energy into computing. Noise is not intentionally produced but results from equipment necessary to maintain reliable operation. Similarly, standby generators exist not because operators expect frequent failures, but because society expects essential digital services to continue during rare disruptions.

Viewing these outputs as interconnected rather than isolated helps explain why discussions surrounding data centres often involve multiple disciplines, including engineering, planning, environmental management, economics and public policy.

MDCO Insight: A data centre produces far more than digital services—it also generates economic opportunities, infrastructure demand and physical impacts that must all be managed together.

Why Every Output Exists

Many discussions about data centres focus on individual impacts such as electricity demand, water consumption, noise, heat, or emissions. While each issue is important, examining them separately can obscure the reasons these outputs exist in the first place.

Noise provides a useful example. Cooling fans, chillers, pumps and transformers generate sound because they are performing essential functions that keep servers operating safely and reliably. Backup generators produce emissions during testing because they must remain ready to supply electricity during emergencies. Heat is released because the laws of physics require electrical energy consumed by computing equipment to be converted ultimately into thermal energy.

In other words, these outputs are not independent problems. They are direct consequences of engineering decisions made to satisfy other objectives such as reliability, safety and performance.

This illustrates one of the central themes emerging throughout the MDCO Explain Series. Many of the characteristics associated with modern data centres arise from deliberate trade-offs rather than technical shortcomings.

Reducing electricity consumption may increase water use if different cooling technologies are adopted. Reducing water consumption may require additional electrical energy. Increasing redundancy improves reliability but requires more equipment, larger buildings and greater investment. Higher levels of security protect digital infrastructure while sometimes reducing public visibility into facility operations.

None of these decisions can be evaluated in isolation. Their implications depend upon local circumstances, available technologies, regulatory requirements and the priorities established by different stakeholders.

Understanding these relationships helps move discussions away from simplistic assumptions towards a more informed appreciation of the complex balancing processes underlying every modern data centre.

MDCO Insight: Most physical outputs associated with data centres are not accidental—they are the inevitable consequences of society’s expectations for reliable, secure and continuous digital services.

Every Flow Reflects Multiple Stakeholder Objectives

Perhaps the most important lesson from this article is that no single organisation determines how a data centre is designed or operated.

Customers define expectations for reliability, performance and security. Investors seek financially sustainable projects capable of generating long-term returns. Developers balance technical performance with commercial viability. Operators focus on safe and efficient day-to-day operations. Governments encourage investment while protecting national interests. Utilities ensure that electricity and water systems remain reliable. Regulators oversee compliance with planning, environmental, safety and technical requirements. Communities seek assurance that development will occur responsibly and fairly.

These objectives sometimes align.

Reliable infrastructure benefits customers, operators and investors alike. Efficient energy use reduces operating costs while supporting environmental goals. Effective community engagement strengthens both public confidence and the long-term sustainability of projects.

At other times, tensions emerge.

Communities may favour quieter operations while operators require additional cooling capacity. Governments may encourage rapid investment while planning authorities require comprehensive environmental assessments. Investors may seek cost efficiency while regulators require higher technical standards. Environmental objectives may encourage reduced electricity consumption, whereas computing demand continues to increase because of artificial intelligence and cloud services.

Importantly, these tensions should not automatically be viewed as failures.

Complex infrastructure projects inevitably involve competing priorities. The objective is not to eliminate every disagreement but to ensure that decisions are made transparently, informed by evidence and with appropriate consideration of all affected interests.

This broader perspective also explains why no single metric can define whether a data centre is “good” or “bad”. Technical performance, environmental stewardship, economic contribution, community acceptance and long-term sustainability all contribute to the overall outcome.

The challenge is not choosing one objective over another, but achieving an appropriate balance between them.

MDCO Insight: The final design of a data centre reflects the combined influence of many stakeholders whose objectives often overlap, sometimes conflict and continually evolve.

The Observatory Perspective

Discussions about data centres often begin with a single issue.

Some focus on electricity demand. Others concentrate on water consumption, planning approvals, economic investment, environmental performance or community concerns.

Each of these perspectives contains an important part of the story.

Yet none tells the whole story on its own.

A data centre is best understood as a system of interconnected flows. Resources enter from the wider world. Infrastructure transforms those resources into digital services. The process creates benefits, opportunities, demands and impacts that extend well beyond the site boundary. Every stage is influenced by engineering requirements, commercial realities, regulatory frameworks, public expectations and broader societal objectives.

Recognising these relationships does not eliminate disagreement. Different stakeholders will continue to assign different priorities to reliability, sustainability, economic development, environmental protection and community wellbeing.

However, a more complete understanding allows these discussions to be based on shared facts rather than incomplete information.

One of the purposes of the Malaysia Data Centre Observatory is to make these relationships more visible. By presenting data centres through an elevated, balanced and holistic perspective, MDCO seeks to reduce information asymmetry, encourage informed dialogue and support better decision-making across the entire ecosystem.

Greater transparency does not guarantee consensus. It does, however, provide a stronger foundation for balancing competing interests and identifying solutions that improve outcomes for industry, government, communities and society as a whole.

MDCO Insight: Better decisions begin with a shared understanding that data centres are not merely buildings, but interconnected systems linking the digital economy with the physical world.
