6. Paper #1
0 Idea
0find out the cost-resource benefits of executing real life
applications on open source cloud platform
0measured by evaluating the empirical data
0 Result(s)
0revealed that the cloud features play key role to improve
cost-resource performance
0memory utilization increase by 22.16%
0direct-indirect cost savings sum up to 40%

7. Paper #1
0 Impact
0extent to which cloud can reduce memory wastage and save
costs is an important issue of research
0no analysis was held before to measure performance of
open source cloud using practical scenario and data
0 Evidence
0comparison of five real life applications
0metrics used –
o Resource Utilization (RU)
o Resource Wastage (RW)
o Direct-Indirect costs (DC and IC)

8. Paper #1
0 Criticism
0well-structured and clarity in presentation
0could differentiate open source cloud with proprietary
cloud services for better understandability
0 Future Scope
0only concentrates on IaaS(Infrastructure as a service)
0need to research on –
o PaaS(Platform as a service)
o SaaS(Software as a service)
o NaaS (Network as a service)
o STaaS(Software Testing as a service)

10. Paper #2
0 Idea
0propose the design of a software testing framework to
provide Test-first Performance (TFP) as a Service to be
incorporated in the existing cloud testing frameworks
0 Result(s)
0introduces a testing framework named IVRIDIO which
offers TFPaaS (Test-first Performance as a Service)
0IVRIDIO adds PTFPC (Plugin for TFP in the Cloud) in the
client-end
0 incorporates the paradigm Convention over Configuration
(CoC)

11. Paper #2
0 Impact
0 Though many research papers addressed cloud testing
frameworks, none specifically addressed TFP to be provided as
a candidate to be executed in the cloud
0 proposes the design of a cloud testing framework IVRIDIO
which extends D-Cloud and AGARIC
0 allows the developers to execute critical test suites along with
the regular development phase, provides a fast feedback,
reduces overall test effort and most of all decreases test costs
0 Evidence
0 The framework is demonstrated briefly in the paper which
focuses on the structural components of the framework as well
as the interaction between them
11/18/2014 Paper Review 11

12. Paper #2
0 Criticism
0 good piece of work
0 The significance of its idea is high and worthwhile
0 presentation is also good and well-structured
0 demonstration of the design of the framework is neat and clear
0 slight modification needed in the title which does not contain
the broad domain of the problem
0 Future Scope
0 design a plugin which will support different cloud based
testing services
0 design a generic architecture

0 Paper Title
Developing Fault Tolerant Distributed Systems by Refinement

11/18/2014 Paper Review 13

14. Paper #3
0 Idea
0present a formal approach to developing distributed fault
tolerant systems
0used the action system formalism as design framework and
followed the technique of stepwise refinement
0 Result(s)
0demonstrates how to specify and refine fault tolerant
components and complex distributed systems composed of
them
0general pattern for abstract specification and refinement of
fault tolerant components (the idealized fault tolerant
components) is presented
11/18/2014 Paper Review 14

15. Paper #3
0 Impact
0distributed systems are usually complex component based
systems
0might have several failure modes, ensuring fault tolerance
of distributed systems is a challenging task
0development process proposed in this paper guarantees
correctness of the system’s fault tolerance mechanisms
0 Evidence
0demonstration of developing distributed fault tolerant
systems includes mathematical notations
0showed by stepwise formalization and validation
11/18/2014 Paper Review 15

16. Paper #3
0 Criticism
0 contains high level terminologies without specifying exact
meaning of them
0 presentation of the paper is also weak and incapable to keep
the attention of the reader
0 mathematical notions are presented without proper
theoretical introduction
0 the significance of the idea is high and can be of great effect for
the domain
0 the overall paper arrangement is not much good, as a result
regular reader may face difficulty to conceive its idea
0 Future Scope
0 extend the proposed technique to fault tolerant distributed
systems with dynamic reconfiguration
