Secure Cloud Computing

The positive factors of the cloud computing: the great commercial value, the cheap and convenient use, has been recognized widely. But there are many risks on security. These security risks will greatly restrict the development of cloud computing. Cloud security risks such as: the cloud platform is easily vulnerable, cloud resources is easily abused, the cloud platform data is accessed by unauthorized user or the data is missing, the violations in the network is difficult to trace and survey, and the service providers replacement will affect the migration of the users data and services. So we research the virtualization technology, data backup and disaster recovery technology, encryption technology of data storage and transmission, the authentication technology of service providers and users, risk assessment, and legal constraints and safety training. Our research is strived to obtain a secure cloud computing environment.

The paper examines one of cloud computing (CC) issues that is the migration process to the cloud computing environment. The purpose of the paper is to create a cloud computing migration model through the analysis of organization's information resource migration process.The paperuses scientific literature analysis and synthesis, proposes visualization and modeling methods, analysis of the factors and criteria that determine the content of the stages of the migration process. Global information technology (IT) research and IT consulting company studies and experience show that the volume of cloud computing applications is constantly rising. The trend was also observed in Lithuanian context. It was foundthat themarket forcloud computing application scenarioscould be possibly used in different areas: for individual users, small and medium-sized companies, large organizations and the public sector. The above observations demonstrate that the growing number of organizations will use cloud computing model to manage their information resources. The future of cloud computing technology users need to understand migration processes and therefore have a defined migration model.

Cloud computing is a type of parallel and distributed system consisting of a collection of interconnected and virtual computers. This technological trend has enabled the realization of a new computing model called cloud computing, in which shared resources, information,software & other devices are provided according to client requirement at specific time, are provided as general utilities that can be leased and released by users through the Internet in an on-demand fashion.Cloud workflow scheduling is an NP-hard optimization problem, and many meta-heuristic algorithms have been proposed to solve it.Allocation of resources to a large number of workflows in a cloud computing environment presents more difficulty than in network computational environments.A good task scheduler should adapt its scheduling strategy to the changing environment and the types of tasks. In this work, modified ant colony optimization for cloud task scheduling is proposed. The goal of modification is to enhance the performance of the basic ant colony optimization algorithm and optimize the task execution time in view of minimizing the makespan of a given tasks set.

In the cloud computing frameworks, when utilizing virtualization technology, the client's mentioned information data or storing away assistance is obliged by a lot of imparted virtual machines (VM) in a scale and flexible way. These VMs are put in at least one server point as per the point stores capacities or probabilities. The VM arrangement accessibility refers to the probability that in any event one lot of all client's mentioned VMs works during the requested. In this research paper we proposed an algorithm for better VM placement load balancing. Allocation is made based on the Assignment Problems arrangement strategy idea, which is planned for cloud computing. Assignment issues whose decision making parameters are summed up numbers as triangular fuzzy set as well as Centroid Ranking Technique is used for ranking the dataset. The linguistic variables are used to change the subjective information into quantitative information. Another positioning strategy is proposed to defuzzify the fuzzy numbers, trailed by Hungarian system for ideal cost and time. A numerical model is proposed methodology for better assignment of VM in the physical machine for cloud computing environment.
