I am looking forward to share my thoughts on ‘Reinventing Performance Testing’ at the imPACt performance and capacity conference by CMG held on November 7-10, 2016 in La Jolla, CA. Cloud seriously impacts system architectures that has a lot of performance-related consequences. Mitigating performance risks moves to SaaS vendors.
