Cloud Based Load Generators For Web Applications And Blogs

Let’s face it, we are in web apps era! All the services that we get are all on the net mostly fetched via a cloud provider such as Amazon Web Services or Heroku or so. We expect lots of people to avail those services and at reasonable latency. Page rendering should in less than a second for people to stay interested.

So how do we make sure the web apps or blogs are indeed capable of delivering the value adds in those fraction of second? We need to make sure 100% that the web apps are responsive, scalable with no bottlenecks.
