Abstract—With the increasing number of users in the cloud, the development of data centers is also
increasing which consumes more energy and has become a major concern financially and as well as
environmentally. The total amount of energy consumption by the data centers of these cloud providers
accounts for 1%-2% of the total electricity production in the world. About 85% of the energy produced in
the world is obtained by unsustainable resources and an urgent need is required to optimize energy
consumption. By doing this, the utilization of resources shouldn't be reduced. With less usage of energy,
most resource utilization ought to be attainable. Green computing is an emerging technology that focuses
on preserving the environment by reducing various kinds of pollution. In order to produce cost-efficient
executions in cloud surroundings, an appropriate task programming strategy is critical. This paper reviews
existing programming rules for cloud data centers and tries to render task scheduling which is meant in
such a way that it does not solely minimize computation value, it additionally reduces cooling.

Cloud computing offers a user-friendly and
on-request network ассеss tо соmmоn соmрuting
resources, mаking it аn enсоurаging stаndаrd fоr bоth

II. LITERATURE SURVEY
In a cloud computing environment, people usually
demand heterogeneous useful resource services (e.g
additionally, lessen energy utilization and time to
execute the process asked through the person.
Therefore, Scheduling and load balancing techniques
are very important in increasing the efficiency of
cloud setups using limited resources.
The Authors in [3] concluded a cooperative web
server model for the heterogeneous cluster. The
model focuses on optimization of task distribution,
server configuration, power, and throughout.
In [4], several green task scheduling algorithms are
used in which some algorithms work for continuous
speeds and other algorithms for discrete speeds.
[5] aimed to predict the resource allocation and
utilization and better queuing strategies that will help
improve energy consumption. Using reinforcement
learning-based resource provisioning and task
scheduling that will help reduce the prices of the
energy of the cloud service providers. The two-step
resource provisioning and task scheduling processor
is designed that is based on deep Q-learning to
improve the results for enormous cloud providers that
receive an extremely large number of requests from
the user in a day. The use of the time of use pricing
and pay as you go policies are used, the paper uses
deep reinforcement learning and semi-Markov
decision process formulation to allocate resources
and minimize the energy
The work proposed in [6] gave task schedules that
minimize the execution time on a power scalable
cluster that maximizes the energy budget. In this, the
author has used a mixture of power profiling and
performance determination.
A green scheduling algorithm is given in [7] which
uses a neural network predictor to predict the future
load demand and the focus is on energy shortage and
global climate change problems.
The Authors in [8] have surveyed issues related to
energy conservation for servers. According to them,
the server is designed to operate at a fraction of its
capacity which helps in creating opportunities for
energy conservation.
The Authors in [9] concluded combined leverage of
DTM methods, distributed DVFS for heat
recirculation values, and recognized multiloop
control robustness and feasibility via OS-processor
collaborations.
[10] proposed reinforcement learning along with
more classic techniques that used the smart resource
provisioning method that they achieved by using
deep reinforcement learning and decision trees to
create an agent called DERP (Deep Elastic Resource
Provisioning). It automatically contacts the provider
about VM instances and places them into a NoSQL
cluster according to the user demands. Adopting this
approach, they reduced energy consumption using
resource allocation
III. DISCUSSION
There are many cloud architectures that are available
in the market but most of them focus only on the
performance of the cloud architecture. However, with
the advancement of cloud data centers, the
requirements of users are being diversified and this
cannot be achieved via traditional scheduling
algorithms. Cloud data centers are laid with
hot-aisle/cold-aisle by fitted pricked floor tile in a
high floor. Computer room air conditioners (CRACs)
as shown in Fig.1, provide air conditioning in the
data center, and also the cold air is flown to the
elevated floors. The air that flows through the front
captures the heat whenever it passes the racks and
departs from the back end of the rack. The hot air that
comes out from the rack is again sent to the air
conditioner's intake that is positioned in the top of the
hot aisles. Every rack is equipped with many chassis,
every chassis ten further equips many computational
resources such as servers or networking devices. A
large amount of heat is released which has adverse
effects to the environment that leads to global
warming. Even though the temperature on the server
is increasing resources are still allocated in order to
produce maximum performance leading to further
heat generation. This is harming the environment as
CRACs are used to cool down the servers and also
harmful gases are released in this process.
Fig 1. The cloud environment
The massive growth of сlоud соmрuting hаs led tо
huge аmоunts оf energy соnsumрtiоn аnd саrbоn
emissions by а lаrge number of servers. Оne оf the
mаjоr аsрeсts оf сlоud соmрuting is its scheduling оf
mаny tаsk requests submitted by users. Minimizing
energy соnsumрtiоn while ensuring the user's QоS
рreferenсes is very imроrtаnt tо асhieving рrоfit
mаximizаtiоn fоr the cloud service providers аnd
ensuring the user's serviсe level agreement (SLА).
Therefоre, in аdditiоn tо imрlementing user's tаsks,
сlоud data centers should meet the different criteria in
аррlying the сlоud resources by соnsidering the
multiрle requirements оf different users. Mаррing оf
user requests to сlоud resources for рrосessing in а
distributed envirоnment is а well‐knоwn hаrd
рrоblem. Therefore we need an energy-efficient task
scheduling technique that will help us minimize the
cost and make a green cloud environment.
IV. CONCLUSION
As per our research, we come to a conclusion that
temperature is one of the crucial parameters that is
supposed to be kept in control keeping the QoS of
users in mind. So we put forward a scheduling
technique that allocates the resources to tasks only if
the allocation does not overheat the cloud
environment. Different from these approaches, we
would like to solve the energy optimization problem
using DRL, which will help us to improve the energy
issue at a new level, such as for scheduling. The
primary benefit of using DRL is that it works better
than any algorithm on the workload that is constantly
changing like the dependencies of incoming jobs. It
will schedule the jobs according to the server
temperature. This system has been curated keeping in
mind the best interest of users as well as the cloud
environment.
