LoadRunner Cloud: Get out your Umbrellas and Rubber Boots

So - today I read about the new HP annoucement for "HP Cloud Assure" and how we are going to help customers to gain more confidence in cloud-based applications. HP Cloud Assure delivers industry-leading IT management solutions as a managed service to help companies gain the benefits of cloud services without sacrificing control and increasing business risk." (just to quote the website). What this really means for quality's sake, is to ensure we don't become too casual about the responsibility for application performance in the cloud. "Don't look at me, man - performance is something the cloud guys do" should not be a common excuse for cutting performance-corners from your test plan.

As a performance tester, I'm reminded of a very large load test I worked years ago where we were running almost 1,000,000 browser connections from load generators all over the world. It was nearly impossible back then to get our quite simple website to scale - the infrastructure had issues, the firewalls had issues, the server-to-server clustering had issues and the database honestly was the last of our bottlenecks to be resolved. The scale of that test is dwarfed by comparison to today's cloud infrastructures, especially when you consider the almost exponential increases in density and computing power. I think that most engineers should be very concerned about the challenges of testing cloud-based applications with LoadRunner.

  • the topology for running an application in the cloud has transformed dramatically...it's not the same ole' web architectures you already know

  • monitoring the system-under-test will be a challenge if you don't have local access to servers and/or proper permissions

  • your capability to conduct root-cause analysis and hunt down a bottleneck in the servers will be limited, sometimes dramatically

So, if you have applications that are hosted out in the cloud or have dependencies on web services running remotely across the internet, you would probably realize a lot of benefit from working with HP SaaS. They have more than 9 years experience conducting performance testing "in the cloud" and by the way, they have some of the best LoadRunner guys I've ever known working there.
