There is certainly a rush from testing vendors to make their testing products scalable to cloud and mobile in last few months. Apica has enriched its existing load testing portfolio with acquisition of ProxySniffer towards middle of this year and still offers a free 20 user license for the product.
Powered by Apica ProxySniffer, the company is offering four flavours for load testing viz. Internal Testing, Pure Cloud Testing, Apica LoadTest Self Service and Apical LoadTest Full Service. While Internal Testing allows to generate loads of upto 100,000 virtual concurrent users, Pure cloud Testing loads upto 200,000 served from AWS data centers with a pay-as-you-go pricing model powered by good old ProxySniffer.
Apica LoadTest Self-Service and Full-Service options allow to create and store scripts for load testing on Apica's premium testing network and Management service respectively. Full-Service can reach a very high usage of upto 2 million virtual users.
Apica sure stands out in comparison to other services launched recently like CloudPerform from Orasi Software or CloudMonkey from Gorilla Logic with an ability to conduct tests from behind a firewall, AWS data centers or from its own premium testing network of over 50 worldwide physical and virtual locations. The company has already been exposing its cloud based services via its partnership with Eucalyptus, the most widely used on-premise cloud computing platform based on AWS compatible API's. For users looking for options, alternatively one another service that really hits the notes of SaaS based load testing is AgileLoad.
