In this article, we will discuss the concept of Energy Efficiency in Cloud Computing.

Let’s begin with a brief overview of cloud computing. 

What is cloud computing?

Cloud Computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. 

To get the most out of this blog, you should brush up on your knowledge of cloud computing by checking out the article Introduction to Cloud Computing.

Now, it is important to understand what do we mean by energy efficiency in general?

Energy efficiency refers to using less energy to get the same job done and, in the process, cutting energy bills and reducing pollution.

Owing to several factors like digital transformation across a huge number of industries, internet penetration, and increased consumption of data across several domains, the cloud computing industry has registered massive growth in past few years.  

Though it is beneficial for businesses, we know that every coin has two sides. 

The benefit of cloud computing comes at the cost of huge energy demands.

In the further sections, we will learn about the causes of increased energy demands and methods to solve the energy efficiency problems in cloud computing.

Cloud computing and Increased Energy Demands

Data centres are the backbone of cloud computing which play a crucial role in making cloud computing successful. 

Data centres consist of servers for storing and retrieving data, air conditioners, cables, etc. This leads to huge emissions of CO2 in the environment. 

To provide reliable and load balancing services to consumers worldwide, the cloud service providers keep the servers ON all the time, which again requires a continuous power supply.

Overloading of the servers leads to a wastage of energy. 

Interestingly, more than data storage, the transmission of data between servers and home computers consumes huge amounts of energy.

To address the need for optimizing energy utilization, the concept of Green Cloud Computing came into existence. 

Green Cloud Computing

It is referred to as the practice of designing, manufacturing, engineering and disposing of computing resources with minimal damage to the environment.

Making Cloud Computing More Environment Friendly

Some of the steps/measures that various organizations are currently taking, to make cloud computing more environmentally friendly are as follows:

  • Increasing the use of renewable energy sources.
  • Building energy-efficient data centres, for instance, by maximizing power usage efficiency (PUE).
  • Recycling of maximum hardware.
  • Adopting reuse of heat from computer servers.
  • Using hardware has longer life spans because they comprise less toxic materials comparatively to the rest of the hardware.

Techniques and Algorithms to Minimize Energy Consumption

Some of the techniques used for minimizing energy consumption are:

  • Dynamic Voltage and Frequency Scaling (DVFS)
  • Virtual Machine(VM)
  • VM Consolidation and Migration

Algorithms used for minimizing energy consumption are:

  • Maximum Bin Packing
  • Highest Potential Growths
  • Power Expand Min-Max 
  • Minimization Migrations

  1. Why there is a need for resource management and energy efficiency in a cloud computing environment?
    The growing demand for Cloud infrastructure has drastically increased the energy consumption of data centres, which has become a critical issue. Hence, energy-efficient solutions are required to minimize this energy consumption.
  2. What is efficiency in the cloud?
    Cloud efficiency is the ability to make the best possible use of cloud resources at the lowest cost with minimal waste and unnecessary effort.
  3. What are the benefits of cloud computing?
    Scalability, Business continuity, Collaboration efficiency, Flexibility of work practices, Access to automatic updates.
  4. What is reliability in cloud computing?
    Cloud reliability is a measure of the probability that the cloud delivers the services it is designed for.
  5. Is cloud computing greener?
    Customers consume 77% fewer servers, 84% less power and reduce carbon emissions by 88% by using the cloud. There is no denying that its positive impact on the environment is just another one of its many positive attributes.
  6. What is virtualization in the cloud?
    Virtualization is the creation of virtual servers, infrastructures, devices and computing resources.
