Testing The World Wide Cloud

Cloud Performance Testing

For all the discussion about the potential opportunities for the world wide cloud, there have been very few real world examples of applications that can take advantage of this idea. Today, in possibly one of the first true killer applications for multiple global cloud providers, SOASTA a provider of cloud based testing platform has announced its new CloudTest Global Platform.

SOASTA has unveiled an ambitious plan to utilize an interconnected series of regionalized cloud providers for global load and performance testing Web applications and networks. They're calling this new service the CloudTest Global Platform, which is commercially available today, and is said to enable companies of any size to simulate Web traffic and conditions by leveraging the elasticity and power of Cloud Computing.

In full disclosure, over the last several months I've gotten to know Tom Lounibos, the Co-founder and CEO of SOASTA quite well. At Enomaly, we've worked on several projects together so I can honestly say Tom is a the kind of guy a young technology entrepreneur (like myself) strives to become. Tom is a visionary and has an impressive resume to prove it. He brings more than 30 years of experience in building early stage software companies as well as leading two companies to successful IPO's. (Remember when there was an IPO market?) Most recently, Tom was CEO of Dorado Corporation, focused on Enterprise Lending Automation. In the world of cloud CEO's Tom is one to keep your eye on.

Back to what I find interesting about this new scheme; traditionally performance testing has been a kind of "best guess" scenario. Although there are many testing frameworks available most of which create a hypothetical experience using a set of static machines typically limited to one or two geographic locations. With the emergence of a global supply of regional cloud providers SOASTA is tapping into almost limitless capacity to test your application environment in a proactive fashion. Until the emergence of cloud based infrastructures testing beyond a few hundred thousand users was impossible, now you can slap together a few regionalized clouds and realistically see how 3 million or more users around the globe will actually experience your application and infrastructure. This is specially important in emerging markets such as China and India where even a low usage site can routinely get millions of users.

I think the the idea of a global testing platform is very intriguing for a number other reasons as well. Although they're pitching "CloudTest" as a testing / performance tool there is nothing saying that it can't be used as part of a proactive monitoring / scaling environment where you periodically test performance thresholds. In this proactive scaling approach you may want to predefine when, where and how you scale your infrastructure based on the real world conditions your users are "actually" experiencing. When your application is in production you could use your performance tools for proactive analysis allowing for BPM and other performance based policies to be defined ahead of time ensuring a consistent Quality of Experience.

In examining the opportunity for a world wide cloud the idea of using the quality of a user experience as the basis for scaling & managing your infrastructure will be a key metric going forward. Scaling based solely on "load" is a relic of the past. The problem is a given cloud vendor/provider may be living up to the terms of their SLA's contract language, thus rating high in quality of service, but the actual users may be very unhappy because of a poor user experience. In a lot of ways the traditional SLA is becoming somewhat meaningless in a service focused IT environment. With the emergence of global cloud computing, we have the opportunity to build an adaptive globalized infrastructure environment focused on the key metric that matters most, the end user's experience. Whether servicing an internal business unit within an enterprise or a group of customers accessing a website, ensuring an optimal experience for those users will be the reason they will keep coming back and ultimately what will define a successful business.
