Application delivery bottleneck in cloud computing background needs to be broken

With the wide application of new information technology and network technology, users ' demand for efficient application delivery in cloud computing background is becoming more and more strong, so it is urgent to need innovative, high-performance load balancing and application delivery products to meet their own needs.

Cloud computing improves high performance application delivery requirements

Internet banking, securities market and fund company's Web site for security reasons, the basic use of the web based on SSL protocol, such as online business services, because no need to install client software, through the browser access, flexible and convenient, and gradually accepted by many users. However, in the rapid increase in access, even with the most configured server, if the number of users more than the increase, especially when some special events after the burst of traffic, the Web page reaction rate will be significantly reduced, then there is a common Web page response blocking phenomenon. In order to solve such problems, in the financial and securities industry, we are exploring how to use cloud computing technology to provide end users with fast and uninterrupted web services and design high-speed online trading platform.

E-commerce Web site for the stability of the system also has stringent requirements to ensure 7x24 stable operation. Because of the great pressure of user access, it is also considering how to improve the stability of the business system through cloud computing technology and provide users with better network services.

In addition, in the government, telecommunications and various industry sectors, is also considering how to use the Cloud computing data Center deployment, the implementation of electronic business applications.

Cloud computing through its high-performance, high reliability, high security, easy to maintain and other characteristics, is being the government, finance, telecommunications and other industries competing in pursuit. However, in the cloud computing system deployment, there is a problem we can not avoid: a large number of virtual host is the core of cloud computing technology, how to effectively integrate so many virtual host, centralized system allocation? In all major network vendors to provide the cloud computing technology solutions, the answer is invariably concentrated here: High-performance application delivery. But how should this high-performance application delivery be implemented? Many of the answers are: Technology exploration ...

So array NX released the new APV series High-performance application delivery products emerged. The new Array APV series employs asymmetric multi-processing (AMP) technology to form a robust speedcore architecture, with multiprocessor, multi-core performance, combined with multiple-channel parallel and port-high speed forwarding at the TCP layer, A huge leap in processing performance has multiplied the performance of the APV series application delivery device. At the same time, because APV is to improve load balancing performance through software technology, the product can be developed two times according to the needs of different users for cloud computing, in order to solve the user's unique application demand of cloud computing load.

APV Cloud Computing Application Load Solution

Below we will use the array receptacle APV8600 (hereinafter referred to as AVP8600) to understand how APV8600 solve the problem of cloud computing load balancing in government affairs, finance, Telecom, business and other industries.

1. High performance load balancing--the foundation of cloud computing system integration

Whether it's government, finance, telecoms or business, cloud computing platforms have this commonality--the need to address the ever-increasing demand for user-application connectivity. However blindly increase the number of virtual machines is absolutely not enough, if you can not apply the user request average to each virtual machine processing, or can not solve the actual problem.

APV8600 with super load balancing processing performance, 800,000 TCP connection requests per second processing performance, not only to meet the growing user application data access requirements, but also the application of the perfect average distribution, sent to the background of many virtual host, to carry out step-by-step processing. While processing application-tier user connection requests, APV8600 's processing power can be increased to 1.75 million user (HTTP) application connection requests per second. This high-performance application load processing capability is essential in large cloud computing data centers.

2, high accurate load balance--the first problem of cloud application

Data centralized storage is another feature of cloud computing platform, but this design also produces some data transmission efficiency problems while improving security. The usual technical solutions are addressed through the iSCSI protocol and the FCOE capabilities of the data center switch. But if a technology is used well, the performance of data transmission and user response time will be more than 10 times times higher----cache. Both real and virtual servers cache the data that the user accesses in memory so that they can be invoked directly the next time they visit. Therefore, when the same user each data call is assigned to the same server, its data calls will be significantly reduced, and response time will be significantly improved. AVP8600 can achieve this goal effectively through the load balancing algorithm of "PI, ha sparse, header" and so on.

In addition, in the cloud computing applications, in order to improve the processing performance of cloud network, all packets may only be transmitted through the two-layer MAC address, and at this time, many load-balancing devices can not support the two-layer MAC address load balancing function, resulting in load balancing function failure! AVP8600 not only can effectively support the two-layer MAC address load balancing, but also can be a variety of load balancing functions through the form of "group strategy" perfect combination. While providing a high precision load balancing function, it effectively improves the response time of cloud computing applications.

3, high security--to ensure the stable operation of cloud computing

Such an application requirement-access security-is present in both financial and business cloud computing platforms. Without losing the application performance, how to ensure the safety and reliability of the user access information is a major problem that users need to solve. AVP8600 provides the ability to provide powerful SSL encryption and decryption processing and integration with CA certificates and client certificates, based on load balancing functions, through the array appvelocity feature. It can make flexible strategy to realize access and authorization based on certificate identity, which is very suitable for the application of commerce types such as online banking and electronic transaction. and the highest 2048-bit SSL data encryption is possible. Thus ensuring the reliability of user data access security.

In the government affairs and the Telecommunication Cloud computing platform, also needs to carry on the effective protection to the network attack. AVP8600 provides Webwall technology with high-performance access control lists (ACLs), network address translation (NAT), and stateful packet detection capabilities, not only to protect against illegal access and Dos attacks, but also to block application-level attacks that some solutions cannot detect. AVP8600 strengthens the core of the system and ensures the real security of the network and its applications. Its rich 2 to 7-tier firewall strategy provides more comprehensive security by setting multi-tier policies. In the test, a tester was used to send a 1.4 million/sec Synflood to attack AVP8600, AVP8600 the CPU occupancy rate was only 8% while defending against attacks and ensuring normal access traffic was unaffected.

4. High reliability-Multi-link load balancing and TCP connection multiplexing

In the cloud computing platform of Government, finance and commerce, many different ISP links are usually used to ensure the reliability of links. AVP8600 can reduce the pressure of server to handle TCP connection applications on the basis of the multiple link load balancing function to enhance the reliability of data connection and TCP connection multiplexing. And can effectively reduce the data flow in the link through the Web page compression function.

High-efficiency application delivery ERA due to array APV8600
