A Brief Overview – Green Cloud Computing

The term “green cloud” combines the words “green” and “cloud” to refer to the potential environmental benefits that green IT services, delivered over the internet, can offer to both individual companies and society as a whole. For a long period, cloud experts are trying to explore the potential benefits of cloud from an environmental perspective. 

• While some use the term to describe the overall environmental benefits resulting from the movement of IT systems to the cloud.
• It would be more accurate to refer to these benefits as the green benefits of cloud computing, rather than a green cloud. 
• Despite this, individual data center operators may make little effort to reduce their carbon footprint but taking reducing the usage of hardware components. 
• The trend toward the growth of cloud computing and increasing pressure to address the environmental impact of data centers are making the development of green cloud environments more urgent.
• A European Commission study published in 2020 found that data centers accounted for 2.7% of the European Union’s electricity demand in 2018. 

We expect that it will increase to 3.21% by 2030 if demand continues at its current pace. The U.S. Department of Energy has estimated that data centers account for about 2% of the country’s total electricity consumption. In a September 2022 report, the International Energy Agency estimated that up to 1.3% of worldwide electricity usage in 2021 was in data centers.

Describing Green Cloud Computing

Cloud computing refers to a range of internet-based services, such as servers, storage, databases, and networking, that businesses can access and use to enhance their agility, scalability, reliability, and overall performance. By leveraging these services, companies can improve their productivity, speed, and efficiency, while also reducing costs associated with maintaining their own IT infrastructure.

Cloud computing can be implemented in several ways, including through on-premises data centers, third-party data centers like Microsoft Azure, Amazon Web Services (AWS), Google Cloud Platform (public clouds), or a hybrid of both. While all three types of cloud computing can potentially be designed to be eco-friendly, large public clouds offer the greatest potential for energy consumption and carbon footprint reduction.

This is because major cloud providers like Microsoft can benefit from economies of scale to achieve greater efficiency in their IT operations, equipment, and data center infrastructure, as well as purchase larger amounts of renewable electricity. Overall, cloud computing offers a flexible and cost-effective way for businesses of all sizes to access powerful computing resources and leverage the many benefits of the cloud.

Ecological Benefits of Green Cloud Computing

Green cloud computing refers to the practice of using environmentally sustainable methods and technologies to design, deploy, and operate cloud computing systems. This includes reducing energy consumption, using renewable energy sources, and minimizing waste and emissions. Let us understand broadly now. 

Reduced Energy Consumption

An on-premises data center is known for its high energy consumption. This is because it needs energy to power various components such as physical servers, storage systems, network devices, and cooling systems. 

• In comparison, cloud environments also require energy to power up these components, but they are more energy-efficient. 
• This is because cloud environments extensively use server consolidation through virtualization, which means that the number of physical servers is reduced. 
• Additionally, automation, orchestration, and dynamic provisioning are used in cloud environments, preventing overprovisioning of virtual machines. 
• Overprovisioning is a common malpractice in traditional data centers that results in wasted storage space and energy. 

Lastly, cloud environments leverage multitenancy, allowing multiple organizations to share resources without sacrificing performance. New-generation hardware systems can provide extensive functionality in the most miniaturized components. 

Reduced Greenhouse Gas Emission

Every stage in the lifecycle of components that make up a data center, including production, assembly, transport, operation, and disposal, contributes to the emission of greenhouse gases (GHG). 

These components include physical servers, network devices, and cooling systems. In contrast, the equivalent components in cloud environments are designed to be more energy-efficient, resulting in significantly reduced GHG emissions throughout their lifecycle. 

This means that the impact of GHG emissions from cloud environments is substantially lower compared to that of traditional data centers. Unlike hardware systems in other sectors of business, cloud-based infrastructure has comparatively the least carbon emissions. 

Dematerialization

Dematerialization is a process that involves replacing physical products with their virtual equivalents. For instance, instead of using a physical server, organizations can use a virtual server or opt for a cloud-based video streaming service instead of a DVD player. 

This practice not only helps in reducing an organization’s overall carbon footprint but also decreases the volume of electronic waste (e-waste) generated when these physical devices reach their end-of-life (EOL). 

By implementing dematerialization, organizations can contribute to sustainable development by reducing their environmental impact and minimizing the generation of e-waste. Green cloud computing is the surefire solution for promoting dematerialization. 

Usage of Renewable Energy Resources

Major cloud service providers like Azure, AWS, and Google Cloud have made a commitment to purchase significant amounts of renewable energy. They do so by obtaining energy certificates indirectly or by directly sourcing electricity from suppliers that generate power from renewable sources like wind and solar farms. 

Moreover, most of these providers aim to shift towards sourcing 100% of their electricity from renewable sources in the foreseeable future. These efforts demonstrate the cloud industry’s efforts to prioritize sustainability and environmental responsibility by reducing their carbon footprint and supporting the growth of renewable energy markets.

Economic Benefits of Green Cloud Computing

Green cloud computing, which refers to the use of environmentally sustainable practices in the design, operation, and maintenance of cloud computing systems, offers several economic benefits. 

• First, it can reduce energy costs by optimizing the use of computing resources and adopting energy-efficient hardware and cooling systems. 
• Second, it can improve the reputation of businesses by demonstrating their commitment to sustainability, which can attract environmentally conscious customers and investors. 
• Third, it can enhance the overall efficiency and productivity of cloud computing systems, reducing downtime and improving the user experience. 

Finally, it can help organizations comply with regulatory requirements and avoid potential fines and legal liabilities associated with environmental non-compliance.

Lift Extra Burden on IT

The migration of workloads to the cloud entails outsourcing a significant portion of IT operations to the cloud provider, including the deployment and administration of hardware, hypervisor management, some areas of security, and more. 

This implies that members of the IT team can free up valuable time that was previously spent on managing and resolving technical issues, and instead focus their efforts on building innovative solutions that can empower the business. 

By delegating IT operations to a trusted cloud provider, businesses can reduce the burden on their IT staff, who can leverage their expertise to explore new opportunities and develop solutions that drive growth and competitiveness. 

This shift in focus from reactive problem-solving to proactive innovation can create significant value for the organization and position it for long-term success in a rapidly evolving technology landscape.

Reduce Costs of Infrastructure

By utilizing the services of a cloud provider, your business can avoid the substantial initial investment required to construct and maintain a data center. Data centers usually cost a lot and the maintenance cost is pretty higher too. 

This is because the cloud provider assumes responsibility for managing the underlying hardware and various components of the data center such as cooling systems, floor space, CCTV cameras, and the physical building itself.

By entrusting these responsibilities to the cloud provider, your business can focus on its core operations and allocate resources toward other critical areas. A single data center can cater to the needs of a variety of businesses altogether, so it saves a lot on infrastructure costs. 

Facilitating Virtual Working and Collaborations

Cloud computing empowers employees to access essential business applications and data from any location and at any time, whether they are waiting for their flight at the airport, commuting on a train, or working from home. 

This capability of remote access and collaboration not only improves employee productivity but also provides organizations with the flexibility to reduce their dependence on physical office space and onsite equipment, furniture, and supplies, thus minimizing associated costs. 

By enabling remote work, cloud computing technology offers organizations the opportunity to leverage a distributed workforce, allowing them to operate more efficiently while reducing overhead expenses.

Expand The Availability of Resources

Major cloud service providers have established robust and resilient IT infrastructures that ensure the high availability (HA) of their services. These infrastructures typically involve the deployment of multiple data centers across different geographic locations that are designed to withstand various types of disruptive events that could otherwise result in extended downtimes, and downtimes are counter-productive for many businesses. 

Achieving the same level of HA capabilities by building an on-premises data center would be impractical or even unfeasible for most businesses due to the substantial capital and operational expenses involved. Especially, if you are planning on running a startup business, it is better to avail infrastructure-as-a-Service from a cloud service provider.

By leveraging the infrastructure provided by cloud service providers, businesses can benefit from the scalability, reliability, and security of their services, which enables them to focus on their core business operations without the need to invest in expensive and complex IT infrastructure, which also requires high maintenance. 

Conclusion

To practice green cloud computing, prioritize energy efficiency by using low-power hardware, optimizing workloads, and reducing idle resources. Choose cloud providers that use renewable energy and implement sustainable data center practices. Finally, minimize data transfer, implement virtualization, and recycle or repurpose old hardware.
