Performance modelling is simulation of the user inputs and then altering the systems' configuration in order to monitor performance of software. Performance modelling rarely incorporated but gradually the users have realized its significance. There are various approaches for modelling and each has its own benefits and hindrances. Performance modelling when applied on the cloud is again a very challenging task. For a good model for specific software users should have a good knowledge about the software working. This paper includes all the important performance modelling approaches.
