A kind of job transfer scheduling algorithm based on Hadoop Deng, Van Tong, Peak cloud environment Service cluster There is a problem of non-uniform distribution in job submission, which leads to the aggregation of jobs at one time, which causes the response time of the job to exceed the user tolerance range. To solve this problem, a queue based job transfer scheduling strategy (JTSA) is proposed under the Hadoop platform using two-level queue technology. The experimental results show that in the case of a sharp increase in the number of operations, the total completion time has little effect and can be more significant ...

Research on the proof model of data holding in cloud storage the Liu Huanan of Zhengzhou University, as the next-generation architecture of the IT industry, cloud computing is more than simply putting applications and databases in a centralized large-scale data center, but with greater flexibility, allowing arbitrary endpoints to participate in cloud service interactions, This is reflected in cloud storage services: entities that provide storage services may be the integration of a variety of providers. This heterogeneous new feature and the incomplete credibility of the storage provider makes it possible to prove the data holdings in the cloud environment.

Security is often a top priority when planning to invest in cloud-based technologies. Of course, in a cloud environment, technology is often outside the network boundaries of an enterprise, so users can use resources instead of physical racks, servers, power systems, and other related devices. One important issue to be sure of is that critical data such as customer data, medical records, and intellectual property rights are not affected by other customer systems and data files. In this article, we will look at another security issue in the Enterprise Cloud environment: internal threats. We will explore deliberate (planned) attacks and accidents based on cloud-critical resources (...).

As companies continue to enter the cloud, it is important to define responsibility by choosing a cloud vendor and signing a contract with the manufacturer. Most cloud environments are characterized by shared security responsibilities and form a continuum. For SaaS environments, SaaS providers assume most of the responsibility. For an infrastructure that is a service (IaaS) or a platform that is a service (PaaS) environment, the vendor's responsibilities are smaller and the customer's is larger. In the IaaS cloud environment (for simplicity, this article will combine IaaS and PAAs), vendors provide the core infrastructure. Which means the basic network ...
