SA2-MCD: Secured Architecture for Allocation of Virtual Machine in Multitenant Cloud Databases

Abstract

Cloud computing is one of the most demanding technology in today's era. At one side, where cloud computing is offering unlimited amount of IT resources to provide exceptional performance in computing but on the other side, it is facing the security issues majorly with public cloud for multitenant cloud environment. Due to the security issues with public cloud, most of the government and private organizations are not moving their private and sensitive data over the public cloud and compromising with the limited IT resources available to them and limited performance from available resources. A solution to secure private space over the public cloud will resolve the aforesaid issues. This paper presents SA 2 - MCD : Secured Architecture for Allocation of Virtual Machine in Multitenant Cloud Databases. This proposed architecture is used for public cloud which provides the private space over multitenant public cloud environment. Moreover, SA 2 - MCD is used for efficient distribution of transactions in distributed databases over the public cloud to offer the secured and remarkable performance. It is useful for both software and hardware level security. Random encryption selection method ( RESM ) for software level security and N_port zoning, F_port zoning, logical unit number ( LUN ) masking, node_port_ID virtualization ( NPIV ), raw device mapping ( RDM ) have been used for hardware level security in SA 2 - MCD architecture. The proposed architecture has been evaluated mathematically and simulated through CloudSim 3.0.3 tool. The experimental results reveal that the proposed architecture SA 2 - MCD gives the better performance as compared to the existing architectures such as T-MMORRS, MGA , DPRA and PRP .
