NETEVENTS2015:SDN and NFV ground flowering safety and standards issues remain prominent

Editor's note: With the deep development of cloud computing,SDN and NFV have been on the ground in the world with cloud-like concepts, and have a certain scale of application in enterprise network and telecom network, but standardized, Security issues are becoming more prominent.

The "NetEvents2015 Global Cloud Computing Innovation Summit" was held in San Francisco, USA, and the summit gathered all aspects of the cloud computing industry chain, including MEF,NTT , VMware , Citrix, Dell, Si Bollen, Infineon, the network, and many other international organizations, operators and manufacturers gathered at the venue, the cloud computing field of hot topics and development trends in-depth discussion.

With the development of cloud computing, the concept ofSDN and NFV , which is associated with cloud computing, has been blooming all over the world, and has been applied to the enterprise network and telecom network in a certain scale. At the same time, standardization, security and other issues that have long plagued the development of cloud computing are becoming more prominent. To this end, in the "NetEvents2015 Global Cloud Computing Innovation Summit", the standardization, security and other issues become the focus of the discussion guests.

where does the Million dollar cake come from?

     Talk about cloud computing, people are always optimistic about its development prospects, there are forecasts that the future of cloud computing market size will reach 1000 sdn IDC predicted to 2018 year sdn 80 billion. Predicting digital exclusively optimistic and positive, it seems that cloud computing is a "place where milk and honey", anyone with a little pay will be fruitful. But is it true?

Jeremiah Caron , Senior vice President of current analysis , reminds people of the cautious optimism about cloud computing. No company is planning to add a lot of investments, according to current analysis's survey of multiple companies. "It's clear that customers are simply moving other areas of investment into cloud computing, which is destined to inevitably compete between cloud providers and other it service providers, especially with traditional it providers. , or even a bitter battle. "Jeremiah Caron said.

If users can recognize the benefits of cloud computing and migrate traditional networks to cloud computing platforms quickly, the competition between cloud service providers and traditional IT vendors will be less intense, but the migration of users to cloud computing is not an overnight move, constrained by various conditions.

Up to now, the server system has experienced the host, client / server, Cloud computing 3 stages of development, these three platforms have their own characteristics, from the actual application, the three platforms have their own living space, There is no complete substitution of the latter phase for the previous phase, so there are three platforms that exist on the market today.

Citrix Vice president Nand Mulchandani believes that the debate about private and public clouds requires a return to what is going on in the cloud, "if you're running a traditional business in a virtual environment, then moving it to the public cloud is no good, and it can be inconvenient." ”

As a result, cloud computing manufacturers face fierce competition from peers on the one hand, but also to deal with the strong traditional IT vendors, so the market competition is very fierce. Jeremiah Caron that, in such a situation, cloud computing manufacturers can only continue to innovate, establish their own differentiation advantage to stand out, and maintain a long-term competitiveness.

Sean Hackett, vice President of 451, said that it was not important for anyone who was a subversive or subversive in the cloud computing market to become more and more powerful. "Just like on the African prairie, the first thing that the antelope opened his eyes every morning was that I had to run faster than the fastest lion, or I would be eaten; at the same moment the lion wakes from his sleep, and the thought that flashes in its mind is: I must catch the fastest antelope, or I will starve to death. " faced with the torrent of cloud computing,every player in theIT market must make themselves stronger," saysSean Hackett . "

Safety is a barrier and an opportunity.

Since the advent of cloud computing, security has been a lingering topic and a key factor affecting the rapid spread of cloud computing. Hosting data in an invisible, confusing, and out-of-control place is a risk for users: is the cloud service provider trustworthy, skilled, and able to call data at any time, without any resistance to transfer to other cloud service providers ' platforms? For users, the security and reliability of cloud computing is fraught with uncertainties.

According to the survey of current analysis, among users who use cloud computing,58% chooses a private cloud,28% chooses a hybrid cloud, with only 15% selected a public cloud. In a survey of "What are the main concerns about the reluctance to use cloud computing", 44% respondents chose security,29% respondents chose reliability,25% respondents chose to protect their privacy.

The survey explains the security concerns of cloud computing: cloud computing is divided into public cloud, hybrid cloud and private cloud 3 forms, in which private cloud security is relatively high, public cloud security is low, most users choose to use the private cloud is due to security considerations.

The security issue is so important that it naturally causes a wide range of concerns in the cloud computing industry chain. "Security is at the heart of everything, and we are working with our partners to create a secure cloud environment. Mike Curtis , deputy Director of Network Marketing, said.

In the eyes of Vice President Nand Mulchandani , the security of cloud computing includes not only data not being stolen and destroyed, but also data ownership-data hosted in the cloud-computing environment, can customers call and extract as freely as possible? He believes that to ensure the security of cloud computing, it is necessary to achieve platform security, operational security, and finally the security of the business operations on the cloud platform. Glenn Chisholm , chief technology officer of Cylance Corporation, stressed that the security of cloud computing is not static, but dynamic, and requires a strong security system.

NTT Americas integrated business manager Tom Gown sees business opportunities from security issues-since security is so important, security can also be provided as a virtual service. Cloud computing is more complex than the past IT service environment, and users do not have cloud computing expertise, do not know how to use devices, set firewall parameters, can not detect security risks early, if the business provider to provide these as services, It will not only ensure the security of cloud computing, but also promote the development of their own business.

The spear and shield of the standardization question

With the development of cloud computing,SDN and NFV , the problem of standardization is becoming more and more important. The lack of a unified standardization system has become a critical issue in the development of cloud computing, SDN and NFV.

     The importance of standardization, opencloud connect ( occ ) chairman jeff schmitz 1904 60 > miles away, the Washington fire brigade only used 38 > The minute was on the scene, but the fire brigade didn't play any role, Because the Washington Fire brigade's water gun could not screw up the Baltimore fire hydrant, in fact, at that time the United States fire hydrant up to 600

In the case of cloud computing,SDN and NFV , although the standard is not unified as the United States fire hydrant interface is not unified as a disaster, but it will seriously affect the industrial process.

UnderIDCsurvey, most companies in the world choose cloud computing not limited to a service provider, but also choose two or more at the same time. IDCThe survey shows that theIaaSaspect, choose to use1Home Service providers have49%, select Use2the home has28%, select3the home has7%, select4the home has6%; inPaaSaspect, the proportions were44%,29%,8%and the3%; inSaaSaspect, the proportions were42%,27%,16%,7%. As a result, cloud computing presents a multi-service provider, in which case it is important to get through the boundaries between different cloud services and to facilitate interoperability and sharing between different cloud services, which demands a unified standard.

In ONF manager Mike McBride , the standardization for SDN and NFV The biggest benefit is the ability to accelerate the progress of the industry and promote the rapid development of technologies and products, thereby promoting SDN and NFV on a large scale.

At present, in terms of standardization, the globalONF,ETSI,IETF,MEFand other standardization organizations, andONOS,Opendaylignt,OPNFVand other open source organizations, to promote standardization has made a positive effort. It is worth mentioning thatMEF,MEFThe Metro Ethernet Forum is a non-profit organization focused on solving the technical problems of Metro Ethernet, in the pastMEFIt mainly revolves around Ethernet, and promotes the development of the industry by promoting the standardization of Ethernet. NowMEFExpand the new realm of cloud computing by setting upOpenCloud Connectadvancing the standardization process of cloud computing.

However, although standardization is a general trend, there is still controversy over whether all of them are based on open source standardization.NTTof theTom GownFrankly, whether it is to follow open source standardization or smuggling has agreement on the road issues,NTTA combination of attitudes was chosen:NTTis aONFThe first private cloud is based on theOpenFlowof the SwitchSDNtechnology;NTTand Cisco,VMwaregood relations have also been established, the latter being the advocates of private agreements. NTTThis choice also takes into account customer needs,Tom Gownsaid that some customers value reliability, not willing to risk the stability and reliability of the open source agreement is not high, soNTTwill consider working with highly reliable suppliers. In fact, the high reliability of the private agreement is unfavorable to the industrial development, the open source standard accelerates the industry progress but the security is low, the two are indeed a pair of contradictory body which is difficult to weigh.

To put aside these contradictions,SDNand theNFVstandardization advancement There are still some problems to be solved. At present, the south-to-interface protocol has evolved and diversified, and the industry has also put forwardOpenFlow,Pcep,netconf,BGPmultiple control protocols, butOpenFlowThe agreement itself continues to evolve, fromv1.0to thev1.5, the content of the agreement has been expanded, so far it has not fully covered all known protocol types, and there is an urgent need for co-ordination. From the north, the current lack of unified standards, but also the relevant industrial alliances to play a role in accelerating the development of north-to-interface, forSDNIndustrial health development and scale deployment to provide the necessary technical support.

The "third type of network" has attracted much attention

As an active Catalystfor SDN and NFV , the "third type of network" proposed by MEF is attracting attention. MEF believes that there are two types of services that people now enjoy: one is a more reliable service, once the service is established, the quality, performance, security of the service is very prominent, but the establishment of such services may take several weeks, especially when the need to cross multiple carrier network time The second is the dynamic, on-demand, ready-to-provide network services, but the quality, performance and security are not up to the user's requirements.

MEF believes that a "third type of network" can be established, combining the advantages of the first two, providing enterprise-class connectivity, providing ubiquitous, on-demand services, but without the arduous and lengthy installation and commissioning process.

MEF also puts forward the concept of LSO(Lifecycle service Orchestration, life Cycle services orchestration), and points out that future networks should include service orchestration capabilities ,API, Protocol-independent NaaS information patterns, and service definitions between physical and virtual service endpoints enable Agile deployment of dynamic services to improve the delivery speed of new enterprise network services. Enable customers to easily configure and manage these products and services through a single Web portal.
