Application portability in a cloud computing condition is characterized to be the exchange of utilization or its segments starting with one cloud administration then onto the next cloud administration of its specialized comparability. The application should be such transferred that it does not make any significant changes in the application code although recompilation or relinking may be allowed. Application portability can be performed by the customer only in case of IaaS and PaaS services because for SaaS the application code relies on the cloud service provider itself. The application artifacts and their dependencies play a major role in the target environment. Containers and their related infrastructure hold valuable importance for application portability. In this paper, we will elaborate on all the issues, challenges, scenarios, and approaches for application portability that rose to date. We will study all the facets of data and application portability such as its instruction, syntax, metadata, and policies. The evolution of automation tools and technologies has made the portability of applications easier as the manual processes were inefficient and error-prone.

Security Issues

Cloud computing is a rising paradigm in today's world. In this, users can send his or her request to any CSP, i.e., cloud service provider, of their choice. In return, the CSP reverts him back with that particular service. Now, while communicating from various two locations, the data transferred is not passed through that much amount of security and privacy as expected. So, there are lots of parameters in the environment that are taken care of while sending, receiving or just passing data over the network. This chapter presents various security issues that are underlying in cloud computing. This chapter has illustrated various issues such as Trust, Encryption, Authenticity, Confidentiality and Multi Tenancy. Also, some of the proposed solutions have also been discussed later in the chapter.

The Cost

Efficient computations are increasing now a day, so their need is very high in the world. Infrastructure and computation techniques are not as much as efficient in conventionally or in present scenario, therefore the cloud computing is new to deal this type of problems. Sequencing of hardware and software technologies, for giving scalable and low cost computational understandings in cloud computing. The major focus of this research is to diminish the transportation cost of resource allocation along with various virtual machines in cloud computing environment. In this research paper, implementation of Vogel's Approximation Method (VAM) to obtain an Initial Basic Feasible Solution (IBFS) and an algorithm to optimize the cost of resource transportations for cloud service provider (CSP) as well as present an example also to understand the proposed method for total supply values and total demand values. Although the calculation of cost reduction until the iteration still has a non-negative values, and the calculation is done again until the last iteration. A comparison has been shown the cost of the proposed mechanism is much less from other technique.

Yao’S Protocol

<p>Cloud Computing Environment provides computing resources in the form of Virtual Machines (VMs), to the cloud users through Internet. Auction-based VM instances allocation allows different cloud users to participate in an auction for a bundle of Virtual Machine instances where the user with the highest bid value will be selected as the winner by the auctioneer (Cloud Service Provider) to gain more. In this auction mechanism, individual bid values are revealed to the auctioneer in order to select the winner as a result of which privacy of bid values are lost. In this paper, we proposed an auction scheme to select the winner without revealing the individual bid values to the auctioneer to maintain privacy of bid values. The winner will get the access to the bundle of VM instances. This  scheme relies on a set of cryptographic protocols including Oblivious Transfer (OT) protocol and Yao’s protocol to maintain privacy of bid values.</p>

Cloud Computing is an emerging field in the IT industry. Cloud computing provides computing services over the Internet. Cloud Computing demand increasing drastically, which has enforced cloud service provider to ensure proper resource utilization with less cost and less energy consumption. In recent time various consolidation problems found in cloud computing like the task, VM, and server consolidation. These consolidation problems become challenging for resource utilization in cloud computing. We found in the literature review that there is a high level of coupling in resource utilization, cost, and energy consumption. The main challenge for cloud service provider is to maximize the resource utilization, reduce the cost and minimize the energy consumption. The dynamic task consolidation of virtual machines can be a way to solve the problem. This paper presents the comparative study of various task consolidation algorithms.

Provider Perspective

One of the most unique forms of contracting is apparent in cloud computing. Cloud computing, unlike other conventional methods, has adopted a different approach in the formation of binding contract that will be used for the governance of the cloud. This method is namely the clickwrap agreement. Click wrap agreement follows a take it or leave it basis in which the end users are provided with limited to no option in terms of having a say on the contract that binds them during the use of cloud services. The terms found in the contract are often cloud service provider friendly and will be less favourable to the end user. In this article, the authors examine the terms that are often found in the cloud computing agreement as well as study the benefit that is entailed in adopting this contracting method. This chapter has undertaken a qualitative study that comprises interviews of cloud service providers in Malaysia. Hence, this study is a novel approach that also provides insight in terms of the cloud service provider perspective regarding the click wrap agreement.

Cloud computing is comprised of major demand from the every group of organization because of easy availability and cost effectiveness. The responsibilities of cloud service providers will become increasing more due to the great progression in every cloud computing deployment model (public, private and hybrid) and service models (SaaS, PaaS and IaaS). In this perspective, cloud computing faces multiple challenges, especially in cloud computing security at all levels (e.g., host, network, application and data levels). Authentication is the constantly the biggest concerned for IT industries to adopt cloud computing environment. The availability, performance, key logger attack, malicious insiders, outsider attacks and service disruptions explore (service hijacking) issues are the key research challenges in the cloud computing authentication level. In this aspect, traditional user name and password is not enough as a single factor (first factor). This paper has proposed a secure cloud computing framework which uses first factor as a crypt user name and password with the ATM pin as a second factor called M-pin. The proposed work focuses on a solution to the threats that are the major issues in the cloud adoption.

The Common

Trust is the common factor of any network security. In cloud, trust is the major factor as this trust develops a relation between the user and resource of the service provider. To develop a strong trust there has to be a strong trust path between two entities. The model proposed builds a strong trust path between two important entities in cloud namely user and resources of the service provider. The trust path thus built strengthens the security of the resources as well as the authentication of the user. The implementation proved that trust model developed is more efficient in terms of computation time.

Data security in the cloud continues to be a huge concern. The adoption of cloud services continues to increase with more businesses transitioning from on premise technology infrastructures to outsourcing cloud-based infrastructures. As the cloud becomes more popular, users are increasingly demanding control over critical security elements of the data and technology assets that are in the cloud. In addition, there are still cries for greater data and security in the cloud. The goal of this paper is to provide cloud service users with greater control over data security in the cloud while at the same time optimizing overall security in the multi-tenant cloud computing environment. This paper introduces cloud-based intelligent agents that are configurable by the users and are expected to give greater compliance for data security in any of the cloud service models.
