10. “In the last 7 years, do you know how many times I have lost any personal
data? Zero.
Announcement Cloud in 1997
Do you know how many times I have backed up my computer? Zero…
I have computers at Apple, at NeXT, at Pixar, and at home. I walk up at any
of them and log in as myself, it goes over the network, finds my home
directory on a server, and I got my stuff where ever I am…
Carrying around these non-connected computers or computers with tons of
data and state in them is Byzantine by comparison.”

12. Cloud testing
• a form of software testing in which
web applications use cloud computing
environments to simulate real-world user
traffic.
en.wikipedia.org/wiki/Cloud_testing
• allows you to use simulated web traffic to „load
test‟ a website or web application with a
flexible, scalable and affordable testing
environment.

• Accessible at Any place, Any time, Any device
• Scalability
• No infrastructural constraints
• No geographical constraints
• Low time to market
• Temporary contract / low costs
•
No installation
•
Availability
•
Usability
•
Possibilites for endurance testing

20. Test Service Level agreement
• Effort driven:
• Number of test cycles per period (including peak and off-peak)
• Through put time (test execution, test preparation, etc.)
• Test or QA activities in general
• Creation of Reports (operational and tactical)
• Result driven:
• Test coverage (quality level) or effort
• Defect detection percentage (DDP)

22. Resume
• The cloud is a TaaS enabler
• The cloud will change the expectation of users
regarding quality
• Cloud services require different test approach
• Cloud test tools allow test teams to:
• avoid high costs on investments
• execute test global tests
• The cloud allows the test community to cooperate
and connect
The cloud has a already a high impact on
Software Testing
…….. and the impact will become huge
Richter magnitude scale representing the energy scale of an earthquake 0 – 6: Micro to Moderate -> Happens often and no or less impact/damageLow impact. Perhaps a small change in specific testing approach, but nothing to worry about.6,1 – 9: Strong -> Happens a few times per year. Damage within a local area. Impact but not killing. High impact. It offers opportunities to optimize our way of testing and our test tooling. Changes will occur but no change in image or fundaments.9,1 – 10: Huge impact, happens a few times in a working-life time. Killing impact on software testing Huge impact. It will change the fundaments and image of the testing profession, like the millennium change did.Regularity -> conformance to standards, policies or law
- What’s the cloud in general – What is the history of the cloud- The cloud and testing – What’s is the cloud currently offering to testing What are the possibilities of the cloud for our testing profession according to me. At last providing some special attention points on testing of cloud solutions.

After the internet bubble Amazon modernized their data centers, because they were only using 10% of the total capacity at any one time.Also triggered by the extending of computer networks to meet the Black Friday peak load.First SaaS solutions were CRM related (like SalesForce.com, Inntact and Salesnet)Amazon S3 (Simple Storage Service)-> first publicly available web serviceGoogle apps (2006 – Gmail) – 2008 site creationMicrosoft Azure (2009) -> SQL Azure Relational Database / Since june 2012 Azure also offers additional services on infrastructural level (like secure site to site network connectitvity)Gartner 2008 -> "organizations are switching from company-owned hardware and software assets to per-use service-based models" Compound annual growth of number of licenses – average growth over a certain period meaning 2012 – 2015 a real growth of almost 50% (and from 2007 of 400%)
