I'm searching since many time a solution,but nothing. I have posted on Spring forum,but no one seems can help me. I appreciate if you can help me.Thank you Antonio

SOASTA Announces Cloud-Based Performance Certification Program
Cloud computing platform vendors, testing companies and independent cloud service providers support the program

SOASTA, the leader in cloud testing, today announced a Performance Certification Program designed to enable companies deploying software in the Cloud, at hosted data centers, or behind corporate firewalls to certify that their website has been tested and has met or exceeded industry benchmarks for performance at peak levels of user traffic. Whether due to cost, complexity or lack of resources, the vast majority of web applications and sites have not been tested at normal user volumes, much less for unexpected spikes in traffic. The user community has become the testers for most Web 2.0 sites, a risk that has proven very costly time and again.

"To our customers, performance matters!" said Lew Moorman, President, Rackspace Cloud. "By utilizing the SOASTA Performance Certification program our customers will have the ability to isolate performance issues before they occur by simulating real world user activity and traffic. Performance certification ensures that websites are being tested, which only leads to greater levels of reliability."

Supporting SOASTA in this performance certification initiative are industry leaders in cloud computing including platform vendors, testing companies and independent cloud service providers. They include 3Tera, Appistry, Chegg.com, Enomaly, GoGrid, Hexaware Technologies, Intuit, JackBe, PowerTest, Rackspace, RightScale, rPath and Zephyr. Concerns over performance and reliability are consistent themes heard by each of these companies when their customers face the uncertainties of extending access to applications outside the firewall, not to mention moving those applications completely offsite. This diverse group of companies represents all aspects of the application lifecycle, from development to deployment, all supporting the need for independent, external validation of end-to-end performance.

Many companies are currently considering or have already moved their applications to the Cloud, typically to lower costs and/or to take advantage of the elasticity of the compute power offered by the Cloud. However, just as in the data center, simply adding low cost servers doesn't solve most performance problems. Performance-related issues, such as latency or an actual website crash, are often the result of a change to the deployment environment, changes in the application itself, or the inclusion of third-party content. The only way to certify a site's performance is by simulating both expected and potential peak traffic while monitoring the impact. With Performance Certification, this is no longer too expensive or too complex to achieve and alleviates additional strain on internal resources.

"Improving performance cannot be achieved solely by adding hardware," said Michael Crandell, CEO, Rightscale. "Web applications and deployment stacks are complex and must be tested under real world traffic conditions to assess what actual performance will be in production.   Having a certification process that ensures sites are tested is an essential element of cloud computing development."

How Performance Certification Works
SOASTA Performance Certification is designed as a turnkey process, minimizing disruption by eliminating any unnecessary impact on the existing environment. SOASTA and its partners collaborate with companies to define common use cases and then simulate those scenarios in the most accurate way possible-by using the web to test the web.

There are a number of purpose built tools to analyze the performance characteristics of individual components of a web-based application, such as web page design, application design, database implementation, or network architecture. SOASTA's Performance Certification leverages its Global CloudTestTM Platform to provide an affordable end-to-end analysis of a site's performance as well as measure responsiveness at normal and peak usage levels. Certified sites receive a comprehensive report on Key Performance Indicators (KPIs), with a focus on response times achieved at various user loads.

Certification confirms that the site has been tested at specific traffic volume levels (1K, 10K, 25K, 50K, or 100K users) and has been measured against KPIs such as response time and error rates. In addition, as part of the certification process SOASTA and its partners provide valuable analysis of site latency to help companies improve the overall performance and responsiveness of their website.

Companies such as Chegg.com, Dell, Intuit and Vovici are just a few of the companies that have had their websites SOASTA Certified. "As traffic to our website continues to grow at record levels, we need to ensure that our site will be able to meet the demand," said Dan Bartow, Manager of Performance Engineering, Intuit TurboTax. "SOASTA enables us to simulate every possible user scenario including massive load. Thanks to SOASTA's Performance Certification process, we are confident that our site will be ready for almost any situation we might encounter."
