Resource request with minimum expenditure by considering different constarints

Resource scheduling in cloud is a challenging job and the
scheduling of appropriate resources to cloud workloads depends on the constraints
and QOS requirements of cloud applications. In cloud environment, user’s
workload with different constraints and the heterogenity of resouces encounters
problems for allocation of resources, which cannot be solved efficiently
existing resource allocation policies..Existing algorithms focus on only one or
two constraints., This paper presents a resource scheduling strategy that
maximizes the resource utilization  as
well as meet the client request with minimum expenditure by considering
different constarints like cost,trust and priority. ie, it combines the existing three resource scheduling algorithm
based on selected constraints and effectively schedule the jobs as per the
request.

I. Introduction

Cloud Computing is an
essential ingredient of modern computing systems. Cloud Computing is an
computing technology that is rapidly consolidating itself as the next step in
the development and deployment of increasing number of distributed application.
Cloud computing is nothing but a specific style of computing where everything
from computing power to infrastructure, business apps are provided as a
service. It’s a computing service rather than a product. In cloud, shared
resources, software and information is provided as s metered service over the
network. When the end user accesses some service is cloud, he is not aware of
where that service is coming from or what is platform being used or where it is
being stored. The cloud computing paradigm makes the resource as a single point
of access to the number of clients and is implemented as pay per use basis.
Though there are number of advantages of cloud computing such as virtualized
environment, equipped with dynamic infrastructure, pay per consume, totally
free of software and hardware installations, prescribed infrastructure and the
major concern is the order in which the requests are satisfied which evolves
the scheduling of the resources. Allocation of resources has been made effi-
ciently that maximizes the system utilization and overall performance. Cloud
computing is mainly sold or rented on demand on the basis of time constrains
basically specified in hours or minutes. So the scheduling has to be done in
such a way that the resource utilization has need done efficiently. In cloud
computing environment, resource allocation or load balancing takes place at two
levels. First, when an application is uploaded to the cloud, the load balancer
assigns the requested process to physical computers, attempting to balance the
computational load of multiple applications across physical computers. Second,
when an application receives multiple incoming requests, these requests should
be each assigned to a specific requested application instance to balance the
computational load across a set of instances of the same requested application.
