    • PAPER REVIEWIntroduction:Cloud computing is the use of computing resources that are delivered as a service over anetwork. Cloud computing entrusts remote services with a users data, software and computation.It is an emerging technology with shared resources, lower cost and relies on pay per useaccording to the user demand. It is defined as the delivery of computing requirements as aservice to a heterogeneous community of end-recipients. The available services are mainlycategorized into three classes- Infrastructure as a Service (IaaS), Platform as a Service (PaaS)and Software as a Service (SaaS).In recent times, Software as a Service is transformed into a new type of service known asSoftware testing as a service (STaaS). It is defined as a model of software testing used to test anapplication as a service provided to customers across the internet. It provides testing supportsuch as load testing, stress testing, performance testing, functional testing, latency testing andcompatibility testing through web browsers.Though being a comparatively newer field, Cloud Testing has become a point of interest formany of the researchers and a plenty of research papers have been published. This documentattempts to reflect the motivations and findings of the papers [1] [2] [3]. Besides, the future workdirectives and some drawbacks which were observed are also mentioned here.Review:#Paper 1: Software Testing Based on Cloud ComputingThe paper provided an overall view of cloud testing. Till now, cloud testing is evolving as a newtechnology. Thus an overview covering all the prime aspects of the field is required for thepeople interested to contribute in it. The paper defines cloud testing keeping the concept of cloudcomputing in mind. Moreover it provides answer to some important research questions: Whichsoftware testing can be performed in cloud? Why do we require cloud testing? How can weperform cloud testing?1|Page
    • PAPER REVIEWThe paper stated that testing such as, hardware compatibility, software environmentcompatibility, software adaptability, functional automation, performance and stress testing canbe performed in the cloud environment. Besides they have identified some of the key reasons ofmoving towards cloud testing which includes- cost savings, improved testing efficiency andmore realistic performance testing. However, security vulnerability and inappropriate choice oftesting application is considered as major threats in their writing.According to this paper cloud testing service can be availed via two methods. One is by using aweb interface and another is by remotely logging into the virtual machine created for the testingpurpose. A general procedure for performing cloud testing was also introduced. The steps are- i)User Authentication, ii) Choosing appropriate resources and platform, iii) Reviewing theapplication and configuring the platform and iv) Payment procedure.Though the paper had provided a nice overview of the cloud testing field, it didn’t discuss themethods of collecting the data thus making the given information less reliable. Moreover, theimplementation details were not covered in the paper. A more detailed information regarding thegeneralized procedure of cloud testing could have added more value to the paper. Nevertheless,the paper helped me a lot to gather the basic knowledge regarding cloud testing.#Paper 2: Research Issues for Software Testing in the CloudThe paper discussed the research issues of testing in the cloud. It focused on the fact that sincethe software development paradigm is shifting towards cloud computing, it implies that themethods, tools and concepts to test them should also change. Therefore, it is important tohighlight cloud computing research issues from a testing perspective. They solicit an academicresearch agenda that puts testing within the fast growing cloud computing context and put up agood resource for the researchers interested this area. They have selected the grounded theory [4]approach to discover the research issues for software testing in the cloud. Grounded theory as anapproach aims at the creation of a theory from the collected and analyzed data. For datacollection, they interviewed eleven organizations and the selection of interviewees was guidedby theoretical and snowball sampling. In order to support their results they compared those withissues gathered from literature.2|Page
    • PAPER REVIEWAfter analyzing the data they had come up with several issues form three different perspectives-Application Issues, Management Issues, Legal and Financial Issues. The application issues are-Applications Suitable for Online Software Testing, Readymade Online Performance TestingPackage for any Customer, Quality Checks for Applications that have been tested in the Cloud,Harmonization of the Test Processes across Multiple Players and Online Testing Solutions forEbusiness Systems. The management issues include- Pool of Testers and Effects on theCustomer’s Business. Finally the Legal and Financial Issues that were discussed are- Test Dataand Pricing Models and Service Descriptions for Testing Services.Finally, the paper provides some vital research questions which should to be explored: Howcloud software development and testing will affect quality requirements in the future- addressingthe interdependency of cloud software development, cloud testing and overall quality assurance?How cloud computing, service oriented architecture, open source development technologies andcrowd sourcing affect an organization’s testing process? The paper had identified some of thekey issues of Cloud Testing from three different perspectives. However, it had ignored a majorperspective- Security Issues. Though in some cases they have raised the point of security, thefield itself is so vast that it demanded more attention. Besides it would also be better if they hadhighlighted the challenges of implementing cloud platform for business organizations.Highlighting the challenges might have provided some more research issues in this field.Overall, this paper was particularly helpful to me as it helped me to gain sufficient knowledge oncloud testing.#Paper 3: Blueprint for the Intercloud – Protocols and Formats for Cloud Computing Interoperability.This paper deals with interoperability protocols and formats for cloud computing. Major concernof this paper is how cloud can ensure the interoperability issue. It finds out the order of protocolthat defines the inter cloud operations. It identifies the fields in which implicit interoperabilitymay be applied. If the idea of implicit interoperability can be implemented in the Cloud Systems,then the communication among different clouds would be much more subtle and smooth. Cloudscan be residing in different geographies, in the form of any VMs. They can be connected by a3|Page
    • PAPER REVIEWcommon set of standards if these ideas can be implemented. IP mobility problem would beremoved. Naming, identity and trust issue would be met. There would be a common set ofstandards for messaging. Standard for multicasting would be set. When services would move aspayloads, a number of issues arise. Renowned company like Google, Yahoo and Apple use theseinteroperability suggestions. So it can be said with confidence that what was stated in this papermeets industry standard.It is possible to reproduce some of the aspects discussed in this paper. But it would needextensive hardware support, as it would need at least two clouds to test interoperability. IPmobility, naming, identity and trust issues are reproducible through normal network. Somequestions are being focused in the paper like what advantage would bring if implicitinteroperability is implemented, is it really worth trying, what standards should be followedwhile setting up clouds, how would we compare different results of different clouds setups etc.This paper doesn’t mention the cloud setup parameters. If one cloud provider wants to consumeservices of other clouds, their functionality must be interpretable. However, this cloud doesn’tdiscuss this issue of different types of cloud. This paper would have been more comprehensive ifit would have stated the implementation strategy of Clouds. Issues of IP assignment,Multicasting etc. aren’t explained in depth.Implicit communication among clouds can have great impact in the emerging and promisingmarket of cloud. Further researchers may work on setting a standard for implicit communicationsamong clouds.Conclusion:The objective of this review was to explore the conditions that influence software testing as anonline service and to find the direction for future research. The findings suggest that softwaretesting as an online service is experiencing a progressive trend. As more and more softwareproducts shift from the traditional desktop form to becoming online services, we can expect thatsoftware testing will follow the same trend. Cloud computing is increasingly becoming themeans through which online services are made available. In view of software testing, cloudcomputing presents two avenues whereby (1) the system under test is accessible online or (2)4|Page
    • PAPER REVIEWtesting infrastructure is hosted in the cloud for example the testing service mentioned in [1].Therefore, research regarding online software testing may benefit from advances in cloudcomputing. Each of the papers introduces a problem that should be addressed. A thoroughexploration may help to take a more standardized way of cloud testing. Therefore, cloudcomputing can be seen as a possible inclusion during future studies.Reference:[1] F. Meng, and W.
