Virtualization encounters "bottlenecks" in traditional data centers, in the process of the IT system construction, the application and storage of 1:1, 2:1, 4:1, 8:1, 12:2 and so on are the corresponding physical configuration, the static load mode can be provided to the application side of the performance, capacity is completely predictable, storage quality is guaranteed. 　　However, the lack of flexibility in this deployment, the basic use of dry manual operations, often take weeks of deployment time, easy to manage islands, and with the passage of time, storage performance is getting worse, affecting TCO. With the cloud ...

You've heard it, but it's worth repeating that the network is a bottleneck in a private cloud. Now that servers and storage technologies have developed into shared resources, cloud administrators are free to invoke these resources, but the network is still manual. To improve flexibility, private cloud networks must be virtualized, and software definition networks (SDN) are a cost-effective approach. "Businesses need to respond quickly, like service providers, to internal customers. To do this, enterprises need to enable self-service it, and the biggest obstacle to this is the network, "is developing based on SDN network virtualization ...

In the era of cloud computing, the data center will be our key hub for application and data delivery, with users accessing data and services from parks, remote branch points, wireless and Internet locations, and networks connecting these services are more important than ever. Cloud computing requires reliable, scale-out, and high-performance networks, from user access to the Internet to data centers. Mass deployment virtualization and cloud computing spawned a workload-centric next-generation data center network that requires a complex network to provide End-to-end network resource responses to workloads. How to respond to business rapid response demand is the next generation of data center network personnel must not ...

Software has always played a very important role as data centers from physical to virtual to cloud, and even to the very hot http://www.aliyun.com/zixun/aggregation/13602.html "> Software definition Data center." But the introduction of software-defined data center (or "software-led infrastructure", as Wikibon calls it), has elevated the status of software to unprecedented heights. Although the hardware of the metal panels, ports and related equipment will not be Beecher ...

Hyper-V is the new concept of a recently virtualized network, with news that many of its most recent features affect network design. In previous articles, we briefly described some improvements in network virtualization and some improvements in virtual machine networks. This article introduces another network improvement: Network card Aggregation (NIC teaming), and a brief introduction to some of the new Hyper-V options for data center design. Network card aggregation is also called load balance failover (load balancing Fail over ...)

"Editor's note" Network after years of development, has come to the "post-Cisco" era, software definition network, network virtualization and other nouns have come to everyone, this article focuses on the traditional network architecture and SDN network of similarities and differences, the development of network virtualization, you can see, SDN manufacturers are gearing up, because of " We usually overestimate the changes in the next two years, and underestimate the changes that will happen in the next decade ", the traditional enterprises need to actively face the future changes in the network operation, the author from the Network Transformation and technology transformation in two aspects of the network industry in-depth discussion of the ...

Fourth Chapter online Retail payment settlement currency: Electronic money electronic money as the latest currency form, since the 1970s, its application has been more and more extensive. E-Money is the payment currency that the main parties of the network retail transaction use to complete the exchange. Without E-commerce, there would be no electronic money. Similarly, there is no electronic commerce without electronic money. [1] Electronic money overview One, the development of electronic money business at home and abroad, the development of electronic money in the late the 1990s, and has been widely concerned by the public and the official institutions.

Currently, VoIP faces security issues of four main: blocking service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. VoIP protocol security is not negligible pain. Information security experts will warn you that if you do not deploy VoIP properly, Internet telephony will be attacked by hackers and malicious code. VoIP can disrupt the security of the network, especially for corporate networks, because companies are eager to deploy this technology and ignore security. Careful analysis can be seen, VoIP first to face the security problem is the lowest ...

Market watchers believe that cloud computing, virtualization and mobile-office trends have become the driving force behind current corporate network changes. They also say that while companies have increased their investment in server, storage and network integration, the problem has not been completely resolved. Recently, reporters interviewed Frost & Sullivan, a researcher in the Asia-Pacific ICT sector, Mayankkapoor. In an interview, Kapoor that virtualization and cloud computing have become the biggest drivers of today's development of regional network markets. These technologies have greatly increased ...

January 25 This year, U.S. President Barack Obama in the United States Congress issued a second State of the Union address since taking office. In his one-hour speech, "Winning the Future" became the topic of high frequency. The third step to winning the future, he suggests, is "rebuilding America's Infrastructure", the most important of which is to provide next-generation high-speed Internet access to 98% of Americans within the next 5 years. On February 3, the Internet Domain name Authority (ICANN) announced in Miami, the United States, that the IPV4 address library has been depleted, a major historical event in the world's Internet. Also means that the next generation of Internet access to ...
