Network Isolation

Hadoop yarn also supports two resource scheduling for both memory and CPU, and in yarn, resource management is performed by ResourceManager and NodeManager, where the scheduler in ResourceManager is responsible for allocating resources, and NodeManager is responsible for the supply and isolation of resources. 　　This article Dong Xi will introduce some of the progress of yarn in resource isolation. Author of the original: resource scheduling and resource isolation is yarn as a resource management system, the most important and most ...

The active immune isolation propagation model in cloud computing network is Xu Rongfei, Van Tong the related elements involved in cloud service abstraction, extracts its ecological defense characteristics, and establishes a Seir class propagation model with active immune isolation function according to the virus propagation theory in artificial immune system. The model can take proactive precautions against virus intrusion. Depending on the degree of network risk, different isolation strategies are adopted to maximize the security of service behavior in the cloud environment. Simulation results show that the model has high adaptability, robustness, intrusion tolerance and self-healing ability.

A secure private cloud storage system based on virtual isolation mechanism Bowa Shaoping Feng Miuga storage technology is an important research direction in cloud computing field, because of privacy leakage and security problems, public cloud storage services are often difficult to be widely used in organizations that hold core data, such as innovative enterprises and armies. A secure private cloud storage system based on virtual isolation mechanism is proposed VI-PCS: The system virtualized physical storage media and public cloud storage services into virtual storage capabilities and services to the system through centralized lifecycle management; The system files stored procedures ...

Recently, the http://www.aliyun.com/zixun/aggregation/35112.html "> Prism Gate Incident has caused a stir in the world," the former CIA employee Snowden revealed the U.S. "Prism" Project monitoring program, There are more than 61,000 cyber attacks on the US National Security Agency worldwide, with hundreds of such actions targeting the mainland and Hong Kong, mainly attacking the network hub, which allows access to 100,000 of computers without invading every computer.

Everyone knows that 2017 double 11 has set a new record, with a total trading volume of 168.2 billion, a peak transaction of 325,000 pens per second, and a peak payment of 25.6 W pens per second.

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

The Construction of Enterprise Security Talk about the Security of Office Network. In most internet companies, the main focus of security building is put on the business network security, and the office network often becomes the short board. In order to avoid textbook-style theory of preaching, this article from the offensive and defensive perspective to medium-sized Internet companies, for example, to discuss the construction of office network security. The office network here is a narrow office network, including only employee office network area, support office erp, e-mail and other systems are not included. Office network infiltration ideas Office network is usually a major breach of hacking, the reason I think the main: office network security into the relative business network is not ...

Security is the key to the healthy development of mobile internet in cloud computing mode. At present, in the 3G network has become mature, mobile internet services have been widely popularized, more and more network and mobile security problems began to appear. Especially with the development of 3g/lte and the introduction of cloud computing Application model, the security problem of broadband mobile Internet becomes more complicated, which brings unprecedented challenge to the security of mobile Internet. Cloud computing virtualization, multi-tenant and dynamic introduced a series of new security issues, mainly in data security, privacy protection, content security, operating environment security ...

Editor's note: The last period of time reproduced in the "5 minutes to understand docker! "Very popular, a short 1500 words, let everyone quickly understand the Docker." Today, I saw the author make a new novel, and immediately turned over. The reason to call this code reading as a fantasy trip is because the author Liu Mengxin (@oilbeater) in the process of reading Docker source, found a few interesting things: from the code point of view Docker did not start a new development mechanism, but the existing tested isolation security mechanism to use the full use, Including Cgroups,c ...
