A Security-Aware Trust-Based SLA Framework Using SDN in Cloud Environment

Software-defined network is an emerging technology in the IT industry. Cloud computing provides the services to the users based on the requirements. Service-level agreement is signed between user and cloud provider. SLA compliance is an important feature in cloud environment. Trust-based SLA is considered for the system. Monitoring of activities is carried out using SDN controller. SDN controller gathers the information completely about cloud provider and cloud user. The main idea of this paper is to monitor and notify any unusual activities such as attacks and hence, trust-based SLA framework is proposed. The framework strongly monitors the malicious users by SDN controller through OpenFlow switches. If the user is found to be unreliable, resources allocated will be released and reallocated to another user. Hence, security monitoring is carried out using SDN controller.
