We know that simply relying on improved hardware performance does not really solve the website http://www.aliyun.com/zixun/aggregation/13996.html "> Load balancing problem." Because the performance of a single server is always limited, generally speaking, a PC server can provide a concurrent access processing capacity of about 1000, more high-end dedicated server to support 3000-5000 concurrent access, such capacity is still unable to meet the requirements of the larger site load. Especially ...

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 network banking, securities market and fund company's Web site for security reasons, the basic use of SSL-based web transactions, such as online business service, because no need to install client software, through the browser access, flexible and convenient, and gradually be accepted by many users. But in the volume of traffic is fast ...

In this article, you will learn which delivery service the PaaS can use and consider which level of multiple defenses to better protect the IaaS and prevent cloud abuse. On a cloud island, PaaS developers often discuss different ways for developers to use IaaS virtual machines on blogs and IaaS network experts. One day, the developer cannot run and test an application. He complained that when he found out it was too late, the virtual machine capacity is not enough to deal with the sudden increase in the large amount of data, which is to meet the growing compliance needs of the ...

1, cloud base cloud, as an extension of it virtualization and automation, is well-known for more and more people, the advantages of the cloud is very obvious, first of all, can make full use of server computing resources, to allocate storage space, flexible scheduling and high reliability of the application of security and data security, can be obtained at any time, on-demand use, 　　Free expansion to achieve good scalability, system architecture flexibility greatly enhanced. As a provincial e-government platform, across a number of urban areas, the overall system includes the provincial backbone platform and the corresponding operation group and management group, as well as the city level of the branch center ...
