Simulation-Based Analysis of a Platform as a Service Infrastructure Performance from a User Perspective

This paper describes analysis of a real-world case where growing up Platform as a Service (PaaS) provider faced and solved problems with scaling cloud-based infrastructure. Scientific, Petri net-based method was used to asses decisions taken by Heroku – the PaaS manager – and legitimacy of claims of the PaaS clients caused by not satisfying efficiency of the new solutions. Exhaustive information provided in the Internet by both parties of the conflict were used in order to create model of the application and infrastructure corresponding to the real case. The model was then used to perform reliable simulations and show that while the client’s claims were well founded, but growth of the PaaS infrastructure forced and justified changes in the management algorithms.
