In a clear nod to the public cloud’s growing popularity, long-time simulation software maker ANSYS began offering what it calls ANSYS Enterprise Cloud beginning this month. ANSYS Enterprise Cloud on AWS is not SaaS (Software as a Service). It’s not the option to use ANSYS from a browser in a pay-as-you-go model. Rather, it’s the option to run ANSYS in a “virtual private cloud,” set up on public cloud provider AWS’s infrastructure. It sounds paradoxical, but it probably makes perfect sense to the IT folks.
