load-balancing

问题 I've found articles that describe issues similar to mine but not close enough. I have a really intermittent problem where one user can land on another users session and end up seeing some of their information that's stored in a session. Here's my scenario: We use AbleCommerce in a load balanced environment using Application Request Routing and Web Farm Framework. We use in-proc sessions but we have sticky sessions (client/server affinity) configured and working. I've verified there is no

问题 We are planning a Biztalk 2009 set up in which we have 2 Biztalk Application Servers and 2 DB Servers (DB servers being in an Active/Passive Cluster). All servers are running Windows Server 2008 R2. As part of our application, we will have incoming traffic via the MSMQ, FILE and SOAP adapters. We also have a requirement for High-availability and Load-balancing. Let's say I create two different Biztalk Hosts and assign the FILE receive handler to the first one and the MSMQ receive handler to

问题 I am new to Google compute engine and I am try to setup network load balancing having 2 VMs for serving web pages. For ex, I have 2 VMs - app1 and app2 - both having apache server and serves simple web page. Both VMs are running with Red Hat Enterprise Linux Server release 7.0 (Maipo) I am able to access both web pages through the IP in browser. I created network load balancing setup and both apps are showing in green in target pool which means load balancer is able to connect to both VMs.

问题 Can the resources of one machine in a web farm be affected to such a point by an app running with Garbage Collection Mode = "server mode" such that the network load balancer will adjust for it? 回答1: Network load balancer is not "sensitive" to GC, in a sense it doesn't know when or where it happens. It may attempt to do some funky stuff with checking the "load" on the machine, but usually it hurts performance and a simple round robin turns out to be better a approach for most of the scenarios.

问题 Just looking for info on what strategies people use for this? In the examples I see it is really easy to make a remote database connection that I will call get() on. var remoteDb = new PouchDB('https://myhost.com/db'); var data = remoteDb.get("myId"); But what if I have several remote databases set up that are syncing with each other. I want the clients to be able to use them all without changing the code. I am considering doing this through dns. For example have db.myhost.com with multiple

问题 Basically, I have 3 servers where 1 of them serves as a load balancing server. In my ASPX page, I want to add a HTML comment to show the IP address or even host name of the server selected by the load balancer. I tried looking through IIS Server variables and tried using SERVER_NAME but that just returns the domain URL. So, is there any way to do this programming in ASP.NET? Thanks! 回答1: How about System.Environment.MachineName 回答2: For IP address: HttpContext.Current.Request.ServerVariables[

问题 I have a web app that accepts api requests from an ios app. My web app is hosted on Heroku using their free dyno which is able to process 512 mb of data per request. Because node is a single threaded application this will be a problem once we start getting higher levels of traffic from the ios end to the web server. I'm also not the richest person in the world so i'm wondering if it would be smart to create another free heroku app and use a round robin approach to balance the load received

问题 I'm trying to configure load balancer to serve in HTTPS with certificates provide by Lets Encrypt, even though I couldn't do it yet, reading this article gives steps how to configure Self-signed certs Network Load-Balancer w/ TLS backend HTTPS Load-Balancer w/ non-TLS backend HTTPS Load-Balancer w/ TLS backend As I'm intersting only in HTTPS, I wonder what is the difference between this two: HTTPS Load-Balancer w/ non-TLS backend HTTPS Load-Balancer w/ TLS backend But I meant not the obvious

问题 I had done simple setup: Backend(website): 1 machine having tomcat installed and serving on 8080. webapps folder of tomcat has two folder 1 withGoogleRule1 |--test.html 2 withoutGoogleRule1 |--test.html Now i have a google-load-balancer setup with below settings Now Backend machine direct ip is http://104.197.37.171:8080/withoutGoogleRule1/test.html Load Balancer url is http://107.178.240.39:8080/withoutGoogleRule1/test.html PROBLEM: No matter how many time we refresh url for direct machine,
