03/11/14 Presentation on Cloud Testing by Sachin Aralikatti2
Agenda
 Introduction to concepts of Cloud
Computing & its services
 Understand the test types supported by
the cloud & how we can leverage Cloud
Computing for Testing

Cloud & Cloud Computing
 Cloud –
 A large number of computers connected through a real-time communication network
 Virtual & shared servers provide software, infrastructure, platform to customers
 Applications are available as hosted solutions on a “pay as you use” basis
 Cloud Computing –
 Computing by the use of a cloud
 Ability to run components of a program or an application on many connected computers at
the same time
 A model where IT networks, Servers, Storage, Applications and Services are shared with
multiple users
 Data is mirrored on multiple servers hence accessible all the time
 Cloud Computing has 3 delivery models….or services….

Cloud Computing Services…

Cloud Testing & the supported types
 Cloud testing is a form of software testing in which web applications use cloud computing
environments (a "cloud") to simulate real-world user traffic
Stress test is used to determine ability of application to maintain a certain level of
effectiveness beyond breaking point
Load Test involves creation of heavy user traffic per requirements and measuring
its response and monitor / tune the performance of any application
Performance Test is all about finding out thresholds & bottlenecks
Functional Testing of both internet and non-internet applications can be
performed using cloud testing. The process of verification against specifications or
system requirements is carried out in the cloud instead of on-site software testing
Compatibility Testing can be made effortless by using cloud environment where
instances of different Operating Systems can be created on demand whilst Inter-
Operability Testing focuses on using cloud environment to test with different
versions of an application
Disaster Recovery Testing helps ensure that an organization can recover data,
restore business critical applications and continue operations after an
interruption of services.
Latency Testing measures the latency between the action and the corresponding
response for / from applications after deploying it on cloud

Cloud Computing leverage
to Testing
Type of Test Cloud Testing Leverage
Stress Testing Ex: Christmas / Boxing Day online shopping (seasonal web traffic)
Load Testing Ex: People accessing www.bbc.co.uk for specific news (geographical traffic)
Performance Testing Ex: Cloud Analytics provide web performance graphs to highlight peaks and
troughs in performance
Functional Test Ex: Local apps can use a billing app hosted on the cloud for an end to end /
integration test
Latency Test Ex: Cloud Analytics provide response time statistics
Compatibility Test Ex: Cloud offers capability to test with different operating systems (Windows,
Mac, Unix, Linux…)
Inter-Operability Ex: Cloud offers capability to test with multiple versions of apps (Browser
Sandbox offered by www.Spoon.net
Disaster Recovery Ex: Cloud servers, storing mirrored data, helps Disaster Recovery testing

CineFunTV – A Case Study
Co. Description & Challenges Advantage of Cloud
 CineFunTV is a media distribution start-up company
and helps provide access to LIVE TV Channels, movies &
other media content from South Asian countries to
expats in the UK and Europe
 CineFunTV needed a high speed dedicated broadband
line accompanied by high performance servers to upload
several Terabytes of video content and allow for users to
search / browse & view the videos from anywhere in the
world
 Tried setting up local servers, 3rd
party vendors and a
few suppliers who all failed to deliver the results due to
large volume data, bandwidth & latency issues
 In addition to the above the CineFunTV Team based in
India had to ensure that end users were able to enjoy
uninterrupted high quality entertainment with minimal
latency issues, by carrying out a wide range of tests and
hence the servers had to be up and running all the time
allowing data access
 Use of Amazon Cloud (Pay as you use) servers / services
reduced the overall costs (monthly cloud usage cost =
$125/Tb for storage + Bandwidth costs) significantly due to
 reduced hardware & setup costs (£1000 to £4000
per server)
 server management & maintenance costs (approx.
£50 to £300 a month per server)
 readily available cloud storage setup accompanied
by high bandwidth facility for video streaming
 24 x 7 global access to data (cost of resources
working 24x7)
 Minimal latency issues due to Amazon’s CDN (content
delivery network) as the content requested by the end user
is delivered from the nearest located CDN node (server)
 CineFunTV team in India can access the data 24x7 as the
cloud servers are up and running all the time

Hybrid Cloud
Private
Cloud
- Single organization
- Self run data centres
- Dedicated Servers
- Guaranteed resources
- Secure front end / networks
- Customised solutions
- Capital intensive
- Setup & Maintenance costs
- Network open for public use
- Shared data centres
- Shared servers
- Shared resources
- Vulnerable to security threats
- Non-customised solutions
- Cost effective
- No Setup & Maintenance costs
- Network/Infrastructure shared between organisations from a specific community
- Shared data centres / servers / resources but with known users from the community
- Costs shared with other users in the community & benefits of cloud are realised
- Composition of 2 or more clouds (public, private or community)
- Clouds remain as unique entities, yet bound together, offering benefits of multiple deployment models
- Enables delivery of specific business service through use of externally available public cloud services
