Businesses are replacing internal resources with cloud-based ones more frequently in order to benefit from features like faster capacity scaling up and scaling down, and access to cloud-based applications and services without having to purchase and maintain on-premises equipment. Cloud computing has greatly arrived. There hasn’t been much discussion so far regarding how efficient and environmentally friendly it is.
Where cloud computing falls on the spectrum of sustainable technology has been a pressing concern for companies wanting to gain credibility in the media and ESG points for being environmentally friendly. Energy and resource efficiency are two important aspects of a green IT strategy that are addressed by cloud infrastructure. As-a-service computing will be more environmentally friendly for the following reasons, whether it is implemented in a private or public cloud configuration. Here we have discussed the reason why cloud computing is green technology. Let’s have a look.
1. Resource Virtualization: Promotes Resource and Energy Efficiency
In order to create cloud-based infrastructure, virtualization is a fundamental technology that enables a single physical server to execute many operating system images simultaneously. Server virtualization facilitates consolidation by reducing the overall physical server footprint, which has environmental advantages. Less hardware is required to operate workloads, which proactively reduces the size of the data center. A data center will use less electricity if it has fewer pieces of physical equipment that need to be plugged in from an energy-efficiency standpoint.
2. Automation Software: Boosts Utilization and Consolidation for Efficiency
Virtualization by itself does not maximize resource and energy efficiencies. Automation software is necessary for cloud-based infrastructure to quickly relocate and scale workloads. Pushing the boundaries of conventional consolidation and utilization ratios, automation enables IT professionals to maximize their investment in cloud-based infrastructure when used in conjunction with the appropriate skills, operational, and architectural standards. Less physical infrastructure is required the higher these ratios are, which maximizes the energy and resource efficiencies from server virtualization.
3. Pay-Per-Use and Self-Service: Promote Life-Cycle Management and More Productive Behavior
In this Cloud Computing, Cloud-based infrastructure’s pay-as-you-go model which encourages users to only utilize what they absolutely need. When self-service is combined with it, life-cycle management will be improved since users can only utilize infrastructure resources when they are actually needed and can turn off resources with predetermined expiration dates. Since customers only use the computing resources they require, when they require them, pay-per-use and self-service capabilities of cloud-based infrastructure simultaneously create energy and resource efficiency.
4. Multitenancy: Offers Scale-Based Efficiencies to Numerous Organizations or Business Units
A shared cloud-based infrastructure can be utilized by numerous organizations or numerous business units inside a single organization. The peaks and troughs of compute requirements flatten by aggregating demand patterns across numerous organizations and business units. The ratio of peak to average loads decreases when automation is added, which lessens the demand for more infrastructure. The end outcome is significant scale- and energy-related economies of efficiency.

Cloud Features for Green Computing
Technology advancements like virtualization and creative cooling techniques increase the capacity of servers to withstand heat and humidity. The energy consumption is reduced by two-thirds because of trends like server consolidation. Additionally, compared to other industries, the IT sector consumes a higher percentage of renewable energy. The primary cloud computing capabilities that enable the decrease of data center carbon emissions are reviewed in the list below.
- Flexible Provisioning
A centralized console or application can deploy virtual machine instances efficiently via dynamic provisioning. If a user application needs more resources, cloud providers are responsible for moving these virtual machine instances to another host. Such deployments may be necessary to meet requirements for high service availability or unstable application loads.
Cloud service providers forecast and track application resource demand, allocating resources as needed. Less resource-intensive apps can be combined into one server. As a result, data centers can continually keep active servers in line with demand. As a result, energy usage is lower than it would be using the conventional provisioning strategy.
- Efficiency of Data Centers
By utilizing energy-efficient technologies, cloud providers can dramatically raise the Power Usage Effectiveness of their data centers. This incorporates improved water or air-based cooling, power supply optimisation, and container-based server design. These technologies enable cloud providers to achieve more power efficiency than conventional data centers and dramatically increase PUE.
Additionally, cloud computing enables businesses to migrate their services to data centers with superior PUE scores by employing virtualized services and high-speed networks.
