Application Load Balancing Architecture

Cloud computing is designed to provide on-demand resources or services over the Internet, usually depending on the size and reliability of the data center. MapReduce is a programming model designed to handle large amounts of data in parallel, dividing work into a collection of independent tasks. 　　It is a parallel programming, supported by a functional, on-demand cloud (such as Google's BigTable, Hadoop, and sector). In this article, you will use compliance randomized hydrodynam ...

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 ...

In this article, we look at the most common use cases for setting up a high-availability (HA) and load-balanced environment: Load balancing enables you to http://www.aliyun.com/zixun/aggregation/13999.html "> Workloads are dispersed across multiple instances, increasing throughput and achieving redundancy. Use case: Load level across two WEB servers running Apache HTTP Server or IBM HTTP server ...

Taobao in the "double eleven" has been an unprecedented response, of course, in the "double eleven" behind, OceanBase distributed system load balancing also helped a lot of busy, the following is the experience of sharing. Cloud computing is now the trend of the times. Its low cost, high performance, high availability, and high scalability coincide with the increasing challenges of Internet applications. It has become a hot topic in the Internet in recent years. Of course, in the underlying cloud computing architecture, distributed storage is an integral part of the indispensable. Like a well-known foreign Internet company Google, Am ...

Design and implementation of dynamic load balancing scheduling algorithm based on feedback in Hadoop heterogeneous environment Nanjing University of Li Yuanhung Benvin in the introduction of cloud computing basic concepts, architecture and application development, based on the analysis of cloud computing model implementation Framework and fault-tolerant mechanism. For the cloud computing Hadoop Open Source Platform, the detailed analysis of the Distributed File System (HDFS, Hadoop Distributed File systems) and the MapReduce computing model, and the operation under the Hadoop platform ...

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 ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

Introduction Cloud application developers and DevOps have successfully developed tens of thousands of applications for IaaS (Amazon AWS, Rackspace, etc.) and PAAs (Azure, Google App Engine, Cloud Foundry, etc.) platforms. These platforms provide basic security mechanisms such as authentication, Dos attack defense, firewall policy Management, logging, basic user and account management, but security concerns remain the primary obstacle to enterprise cloud implementations. Security concerns for the cloud, deploying from a secure configuration ...

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 ...
