11/18/2014 5Paper Review

Paper #1

0 Idea0 find out the cost-resource benefits of executing real life

applications on open source cloud platform

0 measured by evaluating the empirical data

0 Result(s)0 revealed that the cloud features play key role to improve

cost-resource performance

0 memory utilization increase by 22.16%

0 direct-indirect cost savings sum up to 40%

11/18/2014 6Paper Review

Paper #1

0 Impact0 extent to which cloud can reduce memory wastage and save

costs is an important issue of research

0 no analysis was held before to measure performance of open source cloud using practical scenario and data

0 Evidence0 comparison of five real life applications

0 metrics used –o Resource Utilization (RU)

o Resource Wastage (RW)

o Direct-Indirect costs (DC and IC)

11/18/2014 7Paper Review

Paper #1

0 Criticism0 well-structured and clarity in presentation

0 could differentiate open source cloud with proprietary cloud services for better understandability

0 Future Scope0 only concentrates on IaaS(Infrastructure as a service)

0 need 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)

Paper #2

0 Idea0 propose 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)0 introduces a testing framework named IVRIDIO which

offers TFPaaS (Test-first Performance as a Service)

0 IVRIDIO adds PTFPC (Plugin for TFP in the Cloud) in the client-end

0 incorporates the paradigm Convention over Configuration (CoC)

11/18/2014 10Paper Review

Paper #2

0 Impact0 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 Evidence0 The framework is demonstrated briefly in the paper which

focuses on the structural components of the framework as well as the interaction between them

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

Paper #3

0 Paper Title Developing Fault Tolerant Distributed Systems by Refinement

0 Author(s)Elena Troubitsyna

Åbo Akademi University, Dept. of IT

Turku, Finland

11/18/2014 13Paper Review

Paper #3

0 Idea0 present a formal approach to developing distributed fault

tolerant systems

0 used the action system formalism as design framework and followed the technique of stepwise refinement

0 Result(s)0 demonstrates how to specify and refine fault tolerant

components and complex distributed systems composed of them

0 general pattern for abstract specification and refinement of fault tolerant components (the idealized fault tolerant components) is presented

11/18/2014 14Paper Review

Paper #3

0 Impact0 distributed systems are usually complex component based

systems

0 might have several failure modes, ensuring fault tolerance of distributed systems is a challenging task

0 development process proposed in this paper guarantees correctness of the system’s fault tolerance mechanisms

0 Evidence0 demonstration of developing distributed fault tolerant

systems includes mathematical notations

0 showed by stepwise formalization and validation

11/18/2014 15Paper Review

Paper #3

0 Criticism0 contains high level terminologies without specifying exact

meaning of them0 presentation of the paper is also weak and incapable to keep

the attention of the reader0 mathematical notions are presented without proper

theoretical introduction0 the significance of the idea is high and can be of great effect for

the domain0 the overall paper arrangement is not much good, as a result

regular reader may face difficulty to conceive its idea

0 Future Scope0 extend the proposed technique to fault tolerant distributed

systems with dynamic reconfiguration
