Service providers and service consumers in the cloud environment are two important subjects to regulate the cloud computing market and the interests of the game between these two have a certain dynamic. Therefore, in this paper, a framework of SLA negotiation based on evolutionary game theory is proposed in the cloud environment, and the purposes are not only that the parties can negotiate successfully, but also that it clearly demonstrates dynamic evolutionary game process of the participant groups and the internal of the groups. The experimental results show that there are two long-term stable strategies of service providers and service consumers: Firstly, if the service providers take high-quality strategy, then service consumers adopt the high-price strategy; secondly, if service providers take low-quality strategy, then service consumers adopt the low-price strategy. And the analysis by the evolutionary game model and the evolutionary game path shows that the cooperation of the service providers and the service consumers in the consultation are mainly affected by the direct incomes, the distribution percentage, the preferential subsidies, the violation penalties, the violation revenues, the payment costs and other factors .
