Companies are increasingly using cloud computing and investing more and more. The only reason why big-business executives are hesitant about cloud computing is the security of cloud computing. 　　However, most enterprises have no concept of how to safely assess or even reinforce the cloud computing that is about to be used, and therefore it is difficult to reach agreement and consensus on using cloud computing for efficiency and convenience and security two. Based on this, this paper for the risk type of cloud computing using the classic "CIA three", that is, confidentiality (confidentiality), integrity (Int ...).

The 1th part of this series discusses the basic aspects of cloud computing, including the cloud layer and different cloud types and their pros and cons, and explains why it is important for enterprise developers to understand the cloud. The 2nd part explores the public cloud and how to deliver Web applications hosted on the public cloud infrastructure using Ibm®websphere®smash and IBM db2®express-c. This article will refer to ...

Editor's note: Management is an important guarantee for IT system benign operation, different IT equipment has its own management system. In particular, large-scale data centers, must be centralized management system to run the management of computing, storage, network and other equipment to be able to quickly respond to and deal with data center business changes, abnormal events, continuous optimization. In the "IP Navigator" to the period of the article has focused on "data center management", but most of the focus on "network-centric" management, this article will be magnified to the entire cloud computing environment in the data center, the three kinds of operation and management model of the comparative analysis. Traditional number ...

With the rapid development of IT technology, the virtualization technology is becoming more and more mature, and more and more enterprises are starting to deploy the virtualization platform because of its obvious advantages in the capital saving and it efficiency. The number of LPARs in a virtualized platform increases as the business grows, and rapid deployment of the operating system becomes a must. The general deployment of an AIX operating system takes about 50 minutes and requires more human involvement, and takes up a lot of time and effort from the administrator. To improve the deployment speed and flexibility of the system, this article will focus on the existing IBM power V ...

In a larger network of work environment, network administrators can not find an effective way to manage and maintain the network, then his work efficiency will become very low, without reducing the quality of the work of the network administrator will become more intense. Then how should network administrator for their own burden, let oneself from the frequent simple labor liberation? In fact, good at managing a DHCP server is a good way to lighten the network management of the DHCP server, the entire process of the establishment of the most critical, reasonable settings can really make the Internet management once and for all! 1. Set the lease term ...

With the rapid development of SOA (Service Oriented architecture, services-oriented architecture) and cloud computing, all kinds of enterprises are confronted with the great challenges and opportunities brought by this technology development. Many enterprise technology architectures are turning to SOA or a hybrid model built with other architectures, providing services that take full advantage of cloud delivery.

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...
