Server As

In the early stages of development, a single processor can power a server and all its applications. Then it developed into a multiprocessing era, when two or more processors shared a single storage pool and were able to handle more and larger applications. Then a server network appears, each server in the network specializes in different application sets. Now, with the server cluster, two or more servers work like a server, delivering higher availability and performance, far beyond your imagination. Applications can be moved from one server to another, or run on several servers simultaneously-...

Because cloud computing can integrate an enterprise's existing technology infrastructure in an industrialized way, it can bring many benefits while cutting a large number of jobs. In fact, the overwhelming majority of people will agree that cloud computing will certainly bring the industry, business technology and people a huge devastating impact on the way they do business. And for now, it seems that this devastating effect has spread to the labor market. In short, employees are going to start virtualizing like a server. The consequences of using cloud computing is that businesses need ...

Data for the corporate network dark attack and defense war. Data caching, also known as data extrusion, refers to the transfer of data from a computer without authorization. For the corporate network, these types of attacks can be done manually, such as using a USB drive; in addition, this attack can also be automated, when the need to use the network to transfer data. In this article, we will highlight the web-based data caching techniques used during penetration testing, along with the corresponding security hardening measures. As tunneling technology, we assume that we do not have valid domain credentials. This means that I ...

The intelligent home system based on cloud computing Wu Jiaching Li Ai Intelligent Home system based on cloud computing, it is a smart home system which takes cloud server as the core, provides storage and computation, and utilizes sensor technology, close communication technology and network support technology. The system uses a ZigBee home network to connect home devices and connect to the cloud server via the Internet. The user uses the PC or the handheld terminal to monitor, configure and operate the system. This paper presents a new intelligent home system model, which enables the device operators to design and minimize the function and cost of the family.

Using cloud point security services enables organizations to quickly gain the benefits of total cost of ownership (TCO) because it eliminates the need to deploy and configure an enterprise internal Management server. However, some cloud-based security products provide only relatively basic limited functionality, which may make it impossible for an enterprise to gain TCO advantages, or even to the contrary! In assessing cloud-computing endpoint security services, never assume that the functionality provided by the internal deployment product can also be found in the cloud service. This article provides guidance on how to assess cloud endpoint security capabilities from three aspects of deployment, alerting, and reporting. This cloud computing endpoint Ann ...

An electric donkey is a client-side software called Point-to-Point (peer-to-peer)-a tool used to exchange data on the Internet. A user can get files from other users, or distribute files to other users. The ancestors of the electric donkey and other point-to-point client software were a MP3-sharing tool called Napster-although Napster was only a few years older than an electric donkey, the donkey technically surpassed Napster. Napster uses its own central server to connect two points, but the donkey has hundreds of them ...

Editor's note: When it comes to the safety of containers, most people say it's not safe enough to give up the high performance and convenience it brings. The author of this article thinks that Docker has already provided a safe mode, and can be used with all Linux security schemes such as SELinux, as, but many people do not use it well. By comparing bare-metal, VMS and container to buildings, apartments and private rooms, the authors illustrate the problem. Of course, from another perspective, the author only considers the problem of single tenant, the situation of the multi-tenant, C ...
