Cloud Stack Definition

OpenStack has a very high popularity, Cloudstack has plenty of money, Eucalyptus and Amazon established a close relationship. OpenStack, created jointly by Rackspace and NASA in 2010, is undoubtedly highly popular. Now it has established partnerships with giants such as At&t, IBM and Hewlett-Packard, who are committed to OpenStack as the basis for their private cloud solutions. Another open source Cloud platform Cloudsta ...

According to foreign media reports, Juniper Network company in December last year to acquire 176 million U.S. dollars Software definition network (sdn,software tabbed receptacle) contrail Bae, and before that contrail company is not known to many people. Juniper Network launched its own SDN plan one months later, and released the beta code this May. Now that part of the code is ready for a formal launch, the Juniper Network has announced that it will be available to users in open source licensing mode. ...

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 ...

Virtual Machine Management program is a commodity, then where do we go? 　　Virtualized physical computers are the backbone of the public cloud [note] and private cloud [note], enabling enterprises to optimize hardware utilization, enhance security, support multi-tenant, and so on. Early virtualization approaches were based primarily on analog CPUs, such as x86 on PowerPC Macs, enabling users to run DOS and Windows. 　　Not only do you need to simulate CPUs, but you also simulate other components in your hardware environment, including graphics adapters, hard disks, network adapters, memory, and interfaces. ...

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 ...

The definition of cloud computing for some people, cloud computing is synonymous with the Internet. Although in many cases, there is a close correspondence between the two, but in fact there are some differences. The detailed definition of cloud computing is a daunting task, and there is a certain "when I see it, I know". The National Security Technology Agency (NIST) provides a good start on the definition of cloud computing. 　　Although it should not be regarded as authoritative in absolute sense, it can serve as a basis for our discussion. NIST's definition of cloud computing involves three aspects: base ...

First of all, "Wild hope" here is an exotic word, represents a kind of ambition and desire, and when I see the OpenStack Hong Kong Summit Exhibition Board of the manufacturer logo, and the OpenStack foundation of the main members of the list, it will naturally appear in my mind this word, This is also the peak to me a prominent impression, today we will talk about the traditional it giant cloud wild look. OpenStack 2013 Hong Kong Peak Exhibition Board manufacturers logo, the traditional It manufacturers clearly more eye-catching what is the traditional it factory? But ...

With the security it process continues to advance, Yunan defense, cloud computing, cloud storage in the field of security hot; On the other hand, security high-definition, networking and intelligent development, security, especially video surveillance data explosion-type growth, massive data storage and application become a new problem. 　　In this context, cloud storage becomes a necessary choice for security data storage and higher-order applications. As we all know, the rapid development of security applications, especially intelligent city, Safe city, intelligent transportation and other industries in the application of in-depth, security large data such as video surveillance videos, alarm data, and also an explosion of growth. According to I.

From all aspects of the situation, 2012 seems to be a better development of cloud computing year. Over the past year, in addition to being a favorite of all media, cloud computing has reaped a bumper harvest in the number and scope of implementations. While the outlook for cloud computing is promising, cloud computing is largely symbolic of the vendor's financial reporting. Even the optimistic estimate, its market profit is only achieved less than 1% of the total. Cloud providers or potential suppliers are concerned; how can services be transformed into commodities? Lucky ...

When cloud services are running smoothly and service level agreements (SLAs) are in place, business parties, businesses, and institutions may want to transfer data from cloud storage to different providers, but find it impossible to do so for some reason. One reason is that the data format required for API calls to store data in the cloud is incompatible with, or not interoperable with, API calls used by different providers to store data in the cloud. As a result, the business side will be confronted with data transmission failure due to the format used by different providers before choosing a provider to provide cloud services ...
