负载均衡变得简单？ [英] Load balancing made simple?

问题描述

好的，我有两个相同的Web服务器运行Windows 2003 web

服务器。我有一个ASP.NET应用程序，它在

之一上运行得很好。专用的IP地址，在我们的防火墙后面等等。每个人都很高兴。

现在 - 我如何利用第二台电脑来支付
负载均衡网站？它真的会给我的用户带来明显的性能提升吗？你是如何做到这一点的？我读过很多这些MS文章，而且很复杂......告诉我使用负载

平衡硬件和什么不是。什么是最简单，最快捷的方式

通过多个网站获得良好的性能（和可靠性）提升？
服务器？或者，这比仅仅几分钟的

配置设置更复杂吗？ :)

Okay, I have two identical web servers running Windows 2003 web
server. I have an ASP.NET application which runs great on one of
them. Dedicated IP address, behind our firewall, etc. Everyone''s
happy.
Now -- how do I take advantage of that second computer to
"load-balance" the web site? Will it really give my users a noticable
performance increase? How do you accomplish this? I''ve read many of
those MS articles and it''s complicated... telling me to use load
balancing hardware and what-not. What''s the easiest and quickest way
to get a nice performance (and reliability) boost with multiple web
server? Or, is this more complicated than just a few minutes of
configuration setup? :)

推荐答案

当你说相同的服务器时，你正在谈论的是群集，而不是

这是一个简单的活动。没有经验，特别是如果你在本地使用

asp.net会话，而不是通过另一台服务器上的数据库获得

的例子。


不幸的是，我不认为任何人都可以轻易地告诉你如何实现

聚类，你将需要做很多阅读和

试验。

Yo但是你可以考虑以另一种方式提高性能。你有两台服务器，两台服务器都可以使用ASP.NET和IIS6的缓存

功能 - 非常好。您可以根据asp.net

应用程序拆分服务器，在最佳猜测和测试基础上测量使用和平衡

是否单个服务器可以应对您的预期最大值加载，以及

你需要拆分到另一个盒子。例如，您可以从一台服务器渲染所有的图像和文件，而所有的asp.net来自

另一种 - 所有提高性能的好方法，我如果你花时间回顾一下你的解决方案，我相信你可以考虑其他方式。

When you say identical servers, you are talking about clustering and its not
an easy activity for the inexperienced, especailly if your making use of
asp.net sessions locally, rather than via a DB on another server for
example.

Unfortunately, I dont think anyone can easily tell you how implement
clustering, your going to have to do a lot of reading about and
experimenting.

You could however think about performance increases another way. You have
two servers, both capable of making use of ASP.NET and IIS6''s caching
features - which are very good. You could split your server based on asp.net
applications, gauging use and balancing on a best guess and testing basis on
whether an individual server can cope with your expected max load, and where
you need to split off to another box. You could for example render all of
your images and files from one server, and all of your asp.net from
another - all good ways of increasing the performance, I''m sure you can
think of other ways if you take the time to go over your solution.

我已经在另一台计算机上安装了StateServer，并且正在运行

罚款。

我想我正在谈论群集 - 能够嗅出

哪个服务器最适合处理当前请求，基于

cpu ，内存，负载，无论你想要什么叫它。这通常是由固件中的路由设备设置处理，还是全部

软件服务器设置？

关于你的其他评论关于速度增加，我理解

你在说什么...如果我有，比如，

网站的两个重要部分，我可以将一个部分推到另一台服务器并在那里托管了

应用程序，似乎将公司的一半推到另一台
计算机上，致力于这一项任务。我同意它可以增加

的性能，但我不太清楚我是否理解如何将所有

图像或网页本身移动到另一台服务器上可能会增加

表现？与代码隐藏的

DLL和它需要加载的ASPX页面相比，这些东西很小，更不用说SQL

命令，这些命令可能是呈现

页面所需的时间。

你的大多数答案都来自测试你的使用场景，

识别可能的模式失败或高峰使用。如果您有两台服务器执行相同的任务，您可以使用简单的循环DNS随机选择服务器

，或者配置您的路由器以选择基于服务器的服务器客户端IP。

它们主要是实现集群的网络问题。正如我所说，

不幸的是，这大部分只是一个长时间的阅读和学习练习。


关于动态图像和硬文件的评论（word docs等）到另一个

服务器意味着你的asp.net服务器不必处理这些请求。

你的asp.net页面交付速度更快，然后浏览器请求

以典型的

请求方式修复客户端另一台服务器上的图像，从而从asp.net服务器中删除CPU周期

primary目标是处理代码，DLL和aspx文件。这是BBC这样大量网站使用的技术。

Most of your answers will come from testing your scenarios of use, to
identify likely patterns of failure or peak use. If you have two servers
doing the same task, you could use simple round robin DNS to choose a server
at random, or configure your routers to choose a server based on client IP.
They are mostly network issues for a implementing a cluster. As I said,
unfortunately most of this is simply a long reading and learning exercise.

The comment on moving images and hard files (word docs etc) to another
server means your asp.net severs dont have to process request for these.
Your asp.net pages are delivered faster and the browser thenrequest the
fixed things like images from another server at the client side in a typical
request fashion - thus you remove CPU cycles from the asp.net servers whos
primary goal is to process code behind, DLL''s and aspx files. This is a
technique used by very large volume sites like the BBC.
