Question

我想利用Java EE来发展集群和负荷平衡,如果我收到任何要求,我将根据负荷因素向目录提出请求。我要补充一下我的申请失败,并重复会议。建议。

The API for load balncing and clustering that i have to use and where it should be down loaded from?
What are the books that i can make reference to make my application programming?
Is Apache web server is useful to my application or not?
what are the sites that i have to use for developing my application?

Answer 1

我必须使用的平衡负荷和集群的APIC,以及应当从哪里削减负荷?

集群实际上属于Java E规格的一部分,因此,集装箱应当为此提供支持(这里可以理解:集群的斜线是指在你方面进行方案规划,在开发 your EE应用时,你只必须遵守一些规则)。

在Tomcat一案中,对Tomcat s ,更确切地说,是 Tomcators 文件,用于 <<ware/strong>。请注意,许多公司更喜欢使用hardware 负荷平衡解决办法(如F5 BIG-IP或Nortel Alteon等产品)。虽然如此,但费用将略高。

就负荷平衡算法而言,通常使用简单的圆环(这是我的建议)。

对于本届会议的失败部分,你需要使用Persistent Manager,很可能是JDBC Based Store。不要忘记使你在<代码>上投放的物体。

我可以参考哪些书本介绍我的应用方案?

不是确定你通过申请方案意味着什么,而是因为你问这个问题的简单事实,我认为你应该不执行自己的解决办法,而是利用现有的解决办法(软件或硬件)。

阿帕奇网络服务器是否对我的申请有用?

在软件负荷平衡方面,Pharma(+ mod_jk)将是我选择网络服务器。 Refer to the TomcatLinkors documentation previous referred.

我为开发我的申请而必须使用的场所是什么。

同样,我不肯定你通过“开发我的申请”的含义,但迄今为止提供的联系是海事组织的良好起点。如果你想再做一个比喻的话,可能要检查。根据J2EE集群/(这仍然是一条好的条款,即使不是真正的新条款)。更具体的答复,请提出一个更具体的问题:

我认为,Tomcat和Acpa已经具备这一能力:

Answer 3

The API for load balancing and clustering that I have to use and where it should be down loaded from? In my experience, load balancing is best done using hardware like F5 or Cisco ACE routers, not in software.
What are the books that I can make reference to make my application programming? See answer to 1.
Is Apache web server is useful to my application or not? Yes, it s common to put a web server in a DMZ and let it proxy requests into the app server inside the second firewall.
What are the sites that I have to use for developing my application? Can t tell based on the info you provided. It s probably not possible to get an answer to such a broad question here.

Answer 4

There is a good product (open source) called Terracota wich allows you clustering and balance. http://www.terracotta.org/
