The Meaning and Countermeasure of Cloud Outburst

The development of cloud services is not a simple development. It must also take into consideration various challenges facing the current network from the aspects of content security, on-demand capabilities and network connectivity.

According to IDC's survey, cloud computing has become widely prevalent. Only 88.1% of the people in the cloud today are greatly concerned about cloud performance issues, "Radware President & CEORoy Zisapel pointed out a major issue facing cloud computing." Once How to ensure that individual users can get the promised service quality under such circumstances, and how to ensure that if there are too many people who visit the platform, there is a problem with the platform, and how to ensure that if a large number of users visit the cloud platform (this situation is called cloud explosion) Data is not lost. "

Cloud outbreaks pose challenges for operators

Cloud outbreaks are divided into two forms, internal outburst and external outburst. Take the Bank of China's IT system as an example. Suppose that its public cloud computing network is provided by China Telecom. Usually, Bank of China e-banking customers have direct access to bank IDC. However, once the visiting clients increase substantially in a single time, the Bank's internal IDC will cease to exist To provide effective services, for this reason, Bank of China IDC will look for auxiliary resources to complete the service in telecommunication cloud computing. This is called internal outbreak or the bank website directs users to directly access telecommunication cloud computing to complete the service and is called external outbreak.

Internal cloud outbreak, the server from the cloud resources to increase the number of servers to serve customers. It is very difficult for the end user to be completely unaware. First of all, what kind of mechanism to increase service resources, how to determine the existing resources under what circumstances will no longer meet the demand; Second, to increase service resources, without increasing network resources, users still can not get due service; Finally, if not On-demand expansion concept, when faced with traffic bottlenecks, will not be able to effectively improve the network resources.

The outbreak of the external cloud is more complicated, and the entire BOB IT framework needs to be copied to China Telecom as it is, assisting IDC of China Telecom into an IDC. "But the new question comes again. The outbreak of an outlying cloud takes a long time for IDC construction. How can IDC replication ensure that clients like Bank of China get a cloud burst in time?" RoyZisapel said.

Configure on demand to meet the cloud's resiliency needs

According to Roy Zisapel, cloud computing should be a new and easy way to access shared resource pools and take computing resources on demand. In this process, on-demand protection of customer service needs is very important.

In the United States NIST theoretical system, cloud computing has five basic characteristics. Feature 1, Cloud computing needs fast flexibility, enabling customers to quickly access and release resources; Feature 2, there will be a certain consideration of service capabilities to ensure that customers have the ability to provide services at any time; Feature 3, for the user , The purchase is a process of on-demand experience, the customer must be able to understand what they need, and can be purchased according to their highest demand portfolio; Feature Four, cloud computing must have a high-speed network that allows customers at any time with the cloud platform to maintain high-speed connectivity; Feature Five, must have a resource pool, all of the computing resources can work together for customer service.

RoyZisapel pointed out that among these features, the most important thing is how to quickly and flexibly, so that customers enjoy their cloud services without any perception. Both external and internal outbreaks will have a big impact on customer perception.

To this end, Radware put forward on-demand application delivery solution, after the acquisition of Nortel Alteon platform, launched the Alteon5412 application delivery platform, in the case of an appeal, once the cloud broke out, you can use the Alteon platform, the service portals and Alteon phase Connect, let it notify the cloud platform network resource adjustment, the use of Radware's freeware vAdapter, you can dynamically adjust the Alteon device server configuration resources. In this case, the cloud network can keep dynamic synchronization between the switch and virtualization server resources, when the need to increase or decrease, the information will be fed back to the switch, but also according to cloud computing needs to increase the processing performance, the ultimate realization Timely to meet customer service needs.

Joe Skorupa, research vice president at Gartner Group, said: "The advanced application delivery system helps cloud service providers dramatically increase data center efficiency by 20% to 50%. In addition, because application delivery control integrates dynamic caching, Compression, prefetch, and other related Web acceleration technologies, so often helping end users achieve more than 50% performance improvement. "

Currently, in addition to Radware, F5 and Huaxia Innovations have also launched delivery products suitable for cloud computing. Huaxia's innovative asymmetric TCP acceleration technology can speed up TCP / IP-based applications and improve TCP application performance across all WANs by 2 to 5 times. F5 also proposed a new version of BIG-IPv10 for delivery of products for cloud services. Joyent, a leading cloud computing provider, has deployed F5's Application Delivery Controller to enable its virtualized server infrastructure to quickly scale its applications by delivering IaaS by offloading large volumes of traffic and optimizing client-hosted application performance.
