Cloud Testing - Apica's three-sided approach to cloud computing testing

The following is an article about cloud testing from Apica.

"Cloud Testing - Why is it different?

When you test cloud applications, you need to validate and verify specific cloud functionality such as redundancy and performance scalability. For many cloud providers, dynamic instance-creation of new servers based on CPU load and failover to other availability zones come standard.

But does it really work? Is your application written in such a way that it can take full advantage of these features? These are the kind of actionable results you'll get from Apica LoadTest. We will guide you through the jungle of configuration of load balancing and front-end cache system management based on best practices and our experience with a wide variety of cloud projects.

In testing cloud applications, it's also critically important to mimic real user loads. Because it's never a good idea to only test from the same cloud provider or availability zone, Apica has load test servers in all major clouds and locations around the world.

We will test your cloud application to the limit regardless of your backend structure.

Shopatron Avoids Holiday “Scrambles” with BrowserMob Load Testing from Neustar

The following is a good article about load testing from BrowserMob.

"“We want to be ready for the unexpected,” said Dave Cumberland, VP of Engineering for Shopatron in a recent Internet Retailer article on holiday readiness. According to Cumberland, that’s why Shopatron, a provider of integrated ecommerce solutions, conducts rigorous load testing with BrowserMob from Neustar.
With 40% of its annual revenue coming in the fourth quarter, Shopatron needed to perform at its best between Thanksgiving and Christmas. Noted Cumberland, this means a 99.999% service-level agreement and average page loads of 2.5 seconds.
Facing Holiday Website Traffic with Confidence
“We see a lot of orders and a lot of browsing traffic,” said Cumberland. “Everything has to work up to our standards.” In previous years, before Shopatron began its load testing regimen, the company “held our breath” during the holiday rush.
Choosing BrowserMob for its flexible, On-Demand Load Testing service, Shopatron tests thoroughly during the holiday ramp-up, unleashing traffic surges to ensure its site doesn’t slow to a crawl or, worse, crash. “The overall results were tremendous,” said Cumberland. “More than anything, we felt much more confident as we entered the holidays.”

An Introduction to Performance Testing

An interesting article, written by Jim Holmes, about performance testing is as follows:

"If you've been monitoring our roadmap or other announcement channels, you may have heard we’re bringing performance testing to Test Studio. This is a pretty exciting step for us, and it lets us bring some great functionality to help you continue to boost the quality of the software you’re delivering.
I thought I’d take some time to lay down some of my opinions and experiences around performance testing in general as a bit of a lead in to later posts which will showcase our performance testing functionality. I’ll be writing a number of posts over the next few weeks to cover some fundamentals around performance testing.
The phrase “performance testing” can mean a great many things to different people in different scenarios, so covering a few of the different types of tests may be helpful.
Performance Testing is generally an umbrella term covering a number of different, more complex test environments. I’ve also used the term to describe a very simple set of scenarios meant to provide a baseline for performance regressions.
Load Testing generally uses a number of concurrent users to see how the system performs and find bottlenecks

Performance Testing Interview with Jason Buksh

The following is a good article about performance testing by LoadStorm.

" Tags: interview, load testing, performance testing
Jason Buksh is a Technical Test Manager at Expedia in London, England. Jason has extensive experience with performance testing at many companies including HSBC and Siemens. He is skilled with tools such as Rational, Grinder, and Performance Studio. His certifications include LoadRunner.

We appreciate his time to share some good thoughts with us about a topic that gets us excited. Here is his interview with us.

What is your technical background?
I learned to program when I was 13 - it was a vic20, I then swiftly moved onto 6502 for the BBC micro. University studying computer science was an obvious and easy progression for me. First job was writing rendering engines (C++) for virtual reality simulators. I would describe myself as a techie at heart - I’m genuinely interested in how things work. I think having a strong and long background in IT enables me to grasp new concepts easily - which is great when I have to go into different companies and need to understand their systems quickly. I've a 2:1 in Computer Science, ISEB Practitioner and SCRUM Master Certified.

Do you consider yourself more of a software developer or QA professional?

Dirks on Strategy: On testing business strategies Text Size

The following article is an article about stress testing by David Dirks.

"The rush to implement the "next big thing" can often blind us. When you run a business and you're the chief cook and bottle-washer at the same time, who has time to question what looks to be the greatest business strategy ever created?

Stress-testing a business strategy before it's implemented is one way to help mitigate some risk, though you can never eliminate it. Besides, if you own or manage a business, risk is what defines your path to success or failure. Here are a few ways to stress-test your next great business strategy:

- What return-on-your-investment do you need to call your strategy a success? To say "more sales" or "more profits" isn't quite the answer needed here. Calculating and clearly defining the ROI for your time and the resources expended to implement your business strategy is a must, not an option.

Teamcenter Performance Testing Measures Excellent

The following article is about performance testing, from Siemens PLM Software.

"A business unit of the Siemens Industry Automation Division and a leading global provider of product lifecycle management (PLM) software and services has measured excellent results in performance and scalability tests for its Teamcenter® software running on the Microsoft SQL Server 2008 R2 database and Windows Server 2008 R2 operating system. The testing simulated 5000 simultaneous user sessions – which can equate to many more potential users in a typical global environment. Conducted in conjunction with Microsoft and with the help and support of HP and Intel, the test results demonstrate the full enterprise capabilities of the Microsoft SQL Server database for PLM.

Best Practices for SSD Performance Testing

The following article is about performance testing from seagate.com.

"Everyone knows that solid state drives are fast. While speed is great,
consistent performance is essential. That’s because data centers are driven
by service level agreements (SLAs) that demand the same level of fast
storage performance 24×7×365, regardless of the workload complexity or
changing I/O intensity levels. So how can you evaluate the sustainability of
SSD performance?
Criteria for Evaluating SSD Vendors
When evaluating enterprise SSD vendors and products:
1. Ask vendors to have product performance claims validated by a proven,
independent third-party auditor.
2. Make sure the test methodology leverages enterprise workloads that
include predominately random I/Os per second and uses both query and
update operations. Online transaction processing, email, and database
applications deliver these types of workloads.
3. Confirm that the test evaluates and reports on user responsiveness
(eliminating excursions) and latency with respect to changing I/O
intensity levels. This is an important performance consistency indicator
as it shows the level of variance in end-user response time.
4. Ask the vendor to disclose the test duration. One-hour tests are good
to gauge general performance, but insufficient to prove long-term

Day 2 – Morning Session #prognet11 @skillsmatter @simonbrown

The following is an article from gep13's Blog about load testing.

"The second day of the Progressive .Net Tutorials got off to a flying start thanks to Simon Brown (@simonbrown) and his “Load Testing for Developers” session.

First up, I have to give Simon a lot of credit for his preparation for this talk. His blog post clearly listed all the requirements for his very interactive session. This included getting the source code for the application that was being tested, the load testing tool (jmeter) that we were going to be exercising, as well as his slide deck.

Interestingly, his slide deck was in the form of an Evernote notebook, which as well as having the standard slides, also had a set of exercises that were to be completed during the course of this presentation. Normally when I am in a session like this, I fire open OneNote and take notes in there, but for the sake of this session, I closed OneNote . I have to say though, I was impressed with Evernote. I don’t think I will being switching any time soon, but it was very good.

Now, onto the actual content of the session….

I have to say that I was very impressed with the session. Now, I have never done any form of Load Testing, and I was worried that in order to do any there would be this convoluted process to put all the pieces in the right place and get it all working, but this is simply not the case.

A practical approach to firmwide stress testing

The following is a good article about stress testing from SAS High performance Computing.

"Stress tests have been used in the past by risk practitioners in larger banks to assess the impact of a scenario on the value of its portfolio. However, the global financial crisis that began in 2007 generated new interest in stress testing.

The financial crisis revealed weaknesses in the organisational aspects of current stress testing programs. Prior to the crisis, stress testing was performed mainly as an isolated exercise by the risk function within a bank, and results were manually reported to regulators. Further, differing stress events and assumptions used in each model also meant that the outputs could not be easily aggregated into a meaningful, combined result. Results of each model were reviewed independently, making comparison across risk types or assets impossible. The financial crisis also highlighted the use of macroeconomic stress testing as an important part of any stress-testing framework.
