Load Balancer Architecture

January 20 News, a few days ago, the foundation cloud service provider Qingyun Qingcloud announced the introduction of Load balancer (LB) of the private network mode and the router's IPSec Cryptographic tunneling service.       It is reported that the private network lb not only allows users to save the public network of IP, thereby saving it expenditure, but also through the private network lb to build more complex network architecture, so that enterprises with the physical world the same IT environment. Load ...

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 ...

I started serving Windows http://www.aliyun.com/zixun/aggregation/13357.html ">azure" since 2009. During this period I was fortunate enough to build a solution for many customers of all sizes. As the solution grows, I often need to load balance my internal servers. When this article is published, Windows Azure has no built-in solution for load balancing. However, by introducing access control columns to the public endpoint ...

Summary: Discusses architecture reliability to avoid single points of failure that cause critical applications to fail, and to reduce events that can lead to significant economic losses and corporate branding in the event of catastrophic errors. Here are some storage and network diagnostics issues and I need to list the top ten apps in the company. Note that you ask questions that are related to all programs, while others only need to be relevant to a given domain. I'm going to focus on the memory and http://www.aliyun.com/z of the top 10 applications ...

VMware suddenly released its first open source Paas--cloudfoundry this April. In the months since its release, the author has been concerned about its evolution and benefited from its architectural design, and felt the need to write to share it with you. This article will be divided into two parts: the first part mainly introduces the architecture design of Cloudfoundry, from the module that it contains, to the information flow of each part, how the modules coordinate and cooperate; The second part will be based on the first part, how to use Clou in your data center ...

"Editor's note" in the famous tweet debate: MicroServices vs. Monolithic, we shared the debate on the microservices of Netflix, Thougtworks and Etsy engineers. After watching the whole debate, perhaps a large majority of people will agree with the service-oriented architecture. In fact, however, MicroServices's implementation is not simple. So how do you build an efficient service-oriented architecture? Here we might as well look to mixrad ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem. Such a simple service is bound to bring many challenges to the unprepared IT department. 　　We've been through this many times before: the benefits of a technology that are easy to use end up being an unexpected management challenge, such as virtualization, which causes virtual machines to become fragmented, new security risks to smartphones, and instant messaging that triggers corporate governance problems. This article is intended to show IT managers how to maximize cloud computing ...

VMware released the industry's first open source Paas--cloudfoundry. Today, the author has been concerned about its process, of course, from its architectural design to harvest a lot of things, now take out to share with you my feelings. This article is divided into two parts to describe: The first part mainly talks about the architecture design of Cloudfoundry, from the introduction of the module introduced to each part of the message flow, the coordination and cooperation of each module; The second part will be based on the first part, how to use in your data center ...
