Performance Testing Strategy for Cloud-Based System using Open Source Testing Tool
Download as ppt, pdf2 likes1,608 views
This document outlines a performance testing strategy for a cloud-based system using an open source testing tool. It describes introducing virtual users gradually from 1 to 3000 to test response times. Response times remained under 5 seconds for up to 1500 users but slowed for 3000 users. Testing showed faster response for high-speed internet and unloaded servers. The strategy successfully tested the system's ability to handle increasing loads in the cloud. Future work could include hosting the testing tool in the cloud and expanding performance analysis.

Performance requirements that should be
specified are throughput level, latency, capacity
and ability to operate in lower mode level
(Hussain and Abdulsalam, 2012].
This study illustrates the
strategy employed for
conducting performance
testing for a cloud-based
software by using open
source testing tool via
distributed performance
testing approach
Important tasks during and after the performance
test execution of the cloud should involve
environment deployment, monitoring of
environment status, controller-agent model
implementation, logs analysis, analysis of slow
queries, errors visualization as well as statistics
comparison (Lynch, Cerqueus and Thorpe, 2012)
A framework for testing scalability of web
application on the cloud should include software
that serves as HTTP server, load balancer,
database, cache and benchmark tool (Vasar,
Srirama and Dumas, 2012)
Testing cloud application shall also deal with
quality of workload generation, complexity in data
analysis and service level agreement (Zhou, Zhang
and Ye, 2013)](https://image.slidesharecdn.com/mysec2013paper53dhiauddin-131203213351-phpapp01/85/Performance-Testing-Strategy-for-Cloud-Based-System-using-Open-Source-Testing-Tool-3-320.jpg)

2011 Edelman Health BarometerEdelman Japan In Japan, media such as television and newspapers are the top sources of health information, more so than conversations with healthcare professionals. While the majority of Japanese validate information with their healthcare provider, traditional media sources are relied on more heavily than the global average for health news and information. Family and social connections also have significant influence on perceptions of health responsibility and behavior change in Japan.

Smarter Aviation Data Management: Lessons from Swedavia Airports and SwecoSafe Software Managing airport and airspace data is no small task, especially when you’re expected to deliver it in AIXM format without spending a fortune on specialized tools. But what if there was a smarter, more affordable way?
Join us for a behind-the-scenes look at how Sweco partnered with Swedavia, the Swedish airport operator, to solve this challenge using FME and Esri.
Learn how they built automated workflows to manage periodic updates, merge airspace data, and support data extracts – all while meeting strict government reporting requirements to the Civil Aviation Administration of Sweden.
Even better? Swedavia built custom services and applications that use the FME Flow REST API to trigger jobs and retrieve results – streamlining tasks like securing the quality of new surveyor data, creating permdelta and baseline representations in the AIS schema, and generating AIXM extracts from their AIS data.
To conclude, FME expert Dean Hintz will walk through a GeoBorders reading workflow and highlight recent enhancements to FME’s AIXM (Aeronautical Information Exchange Model) processing and interpretation capabilities.
Discover how airports like Swedavia are harnessing the power of FME to simplify aviation data management, and how you can too.

Pivvot maintains a robust internal metadata hierarchy used to support ingestion and curation of thousands of external data sources that must be managed for quality before entering our platform. By using the SQLExecutor, Pivvot can efficiently detect problems and perform analysis before data is extracted from our staging environment, removing the need for rollbacks or cycles waisted on a failed job. This presentation will walk through three distinct examples of how Pivvot uses the SQLExecutor to engage its metadata hierarchy and integrate with its Data Quality Management workflows efficiently and within the source postgres database. Spatial Validation –Validating spatial prerequisites before entering a production environment. Reference Data Validation - Dynamically validate domain-ed columns across any table and multiple columns per table.

Performance Testing Strategy for Cloud-Based System using Open Source Testing Tool

- 3. Introduction & Related Works Performance requirements that should be specified are throughput level, latency, capacity and ability to operate in lower mode level (Hussain and Abdulsalam, 2012]. This study illustrates the strategy employed for conducting performance testing for a cloud-based software by using open source testing tool via distributed performance testing approach Important tasks during and after the performance test execution of the cloud should involve environment deployment, monitoring of environment status, controller-agent model implementation, logs analysis, analysis of slow queries, errors visualization as well as statistics comparison (Lynch, Cerqueus and Thorpe, 2012) A framework for testing scalability of web application on the cloud should include software that serves as HTTP server, load balancer, database, cache and benchmark tool (Vasar, Srirama and Dumas, 2012) Testing cloud application shall also deal with quality of workload generation, complexity in data analysis and service level agreement (Zhou, Zhang and Ye, 2013)

- 9. Findings & Discussion • • • • • • • • The online services system hosted in the cloud platform could response to specified performance requirement of five seconds from 1 user to 1500 concurrent users without any break. At 3000 concurrent users, the system still can response to huge requests without fail but with delay in response time. When the server is under heavy load or many concurrent users are accessing the online services system, a particular end-user may experience slower response time accessing the online services via the client system. End-user with fast Internet connection will access the online services faster than those with slow speed in any server load condition. Cloud platform allows the virtual web servers to be scaled up in order to meet the performance requirements for faster response time Performance testing activities should be planned earlier in the life cycle and not during execution or after execution completed Performance test cases should mimic the real-world scenarios to ensure the reliability of test results Understanding of the performance requirements will help in selection of suitable performance test tools to accommodate different usage profile, loads, strategy and environment setup
- 10. Conclusion • The study has demonstrated the success of the test strategy in measuring the performance of cloud-base system with the support open source testing tool • it is important to have proper planning and come out with realistic scenarios for performance testing • Performance testing should not be treated as “when required” or “when requested” basis. When performance test is done using the right strategy, right scenarios and appropriate testing tool, any system would be able to deal with increasing loads • Future works? Host the performance testing tool in the cloud too Expanded the performance analysis further to not just on response time, but also other aspects such as CPU utilization, memory utilization, disk I/O and network latency Explore other possible real-world scenarios for the system usage to ensure better performance testing coverage
