Internet weekly: cloud computing era of P2P technology
|
Cloud computing has now say is what new technology. And the cloud services based on expensive and people cloud security worries of become a bottleneck of cloud computing development. In view of this, the ancient P2P technology in such new technology stage revealed its unique advantages, for the development of cloud computing can show a new vitality.
Cloud calculative Achilles heel
Cloud computing and P2P infrastructure very similar. They are based on distributed computing, based on its realization technology is also very similar. In cloud computing, computing resources is located in so-called cloud, we can flexible access to. Resource concentrate superior make computing clouds have three significant features:
1. Reliable data storage center allows users don't have to worry about data loss, virus intrusion etc trouble;
2. For the calculation of user-end cloud equipment requirements low, easy to use;
3. Transportation calculation can easily realize resource sharing.
Amazon from abroad to Google's various applications E2, and domestic swarm moves cloud base Settings, various enterprises and even the government has started to do a lot of input to meet cloud computing time arrival, this is ridiculous, but still become a trend. And the cloud services based on expensive and people cloud security worries of become a bottleneck of cloud computing development. In view of this, the ancient P2P technology in such new technology stage revealed its unique essence, can for the development of cloud computing show a new vitality.
Cloud computing is very popular in the U.S. market, but its infrastructure construction and operation cost is high, Google, Microsoft, yahoo, amazon for large sums of money into the company, in China, the development of cloud base is broadband capital such have abundant strength capital company. Capital bottleneck limits the innovative ideas have large enterprise development of entrepreneurship. P2P calculation is don't need too many investment, set up corresponding P2P networks, but to network bandwidth requirements would be higher.
At the same time to cloud computing now usually know the status of clouds and resources are not equal, and the owner of the cloud, and end only belongs to a borrower and ZuLinZhe. This in the open sharing of mobile Internet age formed an interesting paradox. Because it promoted resources can be itself is open, a kind of unequal state so that end users not to fall into a kind of its resources and safe approach, of absolute trust, unless, denying unavoidably shaky. At this time, we might have been known as mentioned the P2P technology.
Google's cloud computing services such as Gmail, ever appeared &to service will long time when machine problems. And amazon's S3 and Microsoft's AZURE also is such. Due to the scale of these services is very huge, so after your problems easily lead to the user, and then the distrust of cloud services have doubts. And Skype have little P2P services such as near as machine events appear large-scale. P2P services compared with cloud computing services may be more attractive. Skype now has more than 900 million users, this suggests that P2P services to also can have a very large size and reliability.
For cloud computing P2P complement.
P2P is peer - short for peer to peer - there are "(in English) equal status, ability, who" colleagues "and" partners "meaning. Thus, P2P also can be understood as "partners to partner" mean, or called peer-to-peer networking. In the technology development, is a kind of based on end-to-end equal relations. P2P peer-to-peer computing is distributed computing in P2P networks, each peer is both server client, namely is also provide service also is to accept service. In such a kind of equality of the atmosphere, private resources still exist in client.
But in resources by dispersing storage to reach optimization allocation at the same time, also because resources, also caused the dispersion of the management of resources itself increased the difficulty. This as C2C mode and B2C e-commerce mode distinction, in traditional cloud computing, because of its relative resources concentrated, can also realize intensive management. And by using a large number of P2P distributed storage, difficult to guarantee the reliability of the resources, which have caused public opinion before the attack on its that it has sharply against (providing content and toxic describe different files), making the network operation very slow or even collapse, user or software using the network did not contribute their own resources, download or delivering the file may have been infected by a virus or Trojan, software may contain spyware, network operators may try to prohibit transfer from the data on the P2P network, tracking Internet users and harassed type or use to attack them and legitimacy in the network did not request to send the information, etc. These problems once people with different purpose monopolist as force-out P2P sufficient and necessary reason. And in cloud computing era, these problems through the cloud services and P2P crossover applications, can get a certain degree of solution.
Through the resources of stored in the cloud, the management of cloud service provider, is usually some large enterprise supervision, easier to content copyright and dinkum sex management. Some popular public resources which can realize the sharing by cloud services.
As for some private resources, on the one hand, can pass build private cloud realized. Private cloud is cloud infrastructure and software and hardware resources within the firewall, create for institutions or enterprise internal departments Shared resource. Create private cloud, besides hardware resources outside, general and cloud equipment software; Now open source software mainly has the cloud equipment by NASA and Eucalyptus and Rackspace Hosting provider jointly developed Hosting OpenStack. Including OpenStack is a free open source platform to help service providers to achieve similar to amazon EC2 and S3 infrastructure services. Rackspace says its goal is to promote interoperability service development, or rather allow customers in the cloud service providers, make its move workload between not locked.
While the private cloud effective application can rely on the P2P technology, mature in friendly to the resources sharing between the. But at the same time, unfamiliar to achieve a server locks, the purpose of illicit.
