Any hosting company providing load balancing in from of 2 VM'S on separate nodes?
Look for a low cost solution to run an ATOM server on 2 separate nodes. No need for web sites, control panels, etc.
Just Jetty or apache + atom + postgres.
I have come across a number of hosts who offer Load Balanced hosting. I know that load balancing has something to do with distributing the requests to a cluster of servers. Bu how does it actually work?
What happens if I host my website on load balance hosting provider? Will copies of my website be placed on different servers and the website will be served from the server with the least load?
Has anyone any experience of using Load Balanced Clustered VPS servers?
If so who would you rate the best provider?
I have set up a HA network.
Web Servers #1 and #2 have their own IPS, but share a dedicated load balanced IP via the H5 Load Balancer.
We have our domain name registered with Yahoo!
How do we point the domain name at Yahoo! to the load balanced IP?
We have setup and are currently testing a load balanced cluster using heartbeat and ldirectord. One of the problems we have come across is that we are unable to reliably use the same web server for connections from the same user. As a result the php sessions are getting in a bit of a muddle.
Obviously its not something that we can easily sync between servers like the customers other web content. We are looking at either storing the sessions in a database or NFS.
The site is pretty busy and we are a bit worried that when the site goes live both these options will slow everything down.
Apart from using different load balancing software is there any other solutions we could use for this? Has anyone stored php sessions in a database on a busy site or on a NFS?
I currently have one server a
Dual Xeon 5130 2GHZ (woodcrest)
2GB Ram.
Running cPanel/WHM
Now I run a website that is VERY PHP & MySQL Intensive and MySQL is ALWAYS the top of the process list, hogging a ton of usage. It's getting to the point where the site is needed a second server and I know there's a few options; but I'm not sure which one would be the best.
They way I see it my two options are getting a 2nd server and setting up the two to do load balancing, or getting a 2nd server and setting one up for just Apache and the Other for MySQL and using the 2nd as a remote SQL server.
If I do the Apache on a seperate server would I need such a powerful server? And if I also would want to upgrade this server along with getting a 2nd server would I be better of upgrading to 4GB of RAM or upgrading the processors?
One of our customer is looking to use wild card SSL on one of his site hosted with us, he needs clarification on following.
Quote:
We want to have load balanced site serving contents from three different Apache on different physical machines. Site needs SSL security and we will have wildcard SSL for it. However, since the CSR is generated from one apache, will the SSL certificate give errors or alerts if the request is transferred to other apache?.
This is something I am not aware of, infact no such need come thru.
My host [in USA] that I only use for php/mysql points to my static content CentOS server [in Japan] in my house connected to my CATV. At least for testing (outside my house) I can't notice any bad latency since my USA host just serves up small HTML code dynamically and the static content (up to 100k-500k per file) is already available inside Japan. I want to keep (and scale up, if needed) my php/mysql in USA due to language and other issues so I'm hoping (?) as the number of users goes up (or any other issues I can't think of now) latency does not become a problem just for the html. Any comment on that?
My next step to "create" balanced static hosting in Japan is to get two different VPS accounts here in Japan (on two different physical servers) and use php to randomly select which VPS will provide the static content when a user logs in. PHP will also test to make sure the static server is active. If it is down the code will direct to the other server. If my project grows I will - on the Japan side - get more VPSs or even multiple dedicated servers and use the php to manage this "balanced" system like I described.
I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.
Copy these into the browser:

And when i run cat /proc/user_beancounters:
i18.photobucket.com/albums/b106/gnatfish/beancounters2.jpg
This line is particularly scary:
numtcpsock 164 164 166 166 7321
What do i need to do, to get the website running again? It's only one site on the vps a proxy. So i thought a vps would be able to handle one proxy.
Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts
I just got a futurehosting VPS recently and something is puzzling me. Is it normal that an idle CPanel virtuozzo VPS that has no sites on it should display "top" loads of between 1 and 4 regularly? I've been watching the load for a bit now and it keeps jumping between 0-4. When it goes 1 or above, the WHM panel becomes really slow, timing out... They seem to use a beast 8 core machine, so it would take some activity to cause even a 1 load..
I do not have much knowledge about VPS hosting, on a dedicated I would expect the loads to stay 0-0.2 at this point... Is the 1-4 load showing the result of heavy usage by other VPS users on the node? There is absolutely nothing that could cause a load in my vps as far as I see... Is this perfectly normal on any VPS?
You think this is funny? Not at all.
I'm on LON03 server and I recive yesterday from Future Hosting this advise about hight load.
I got then 1 month ago, and the solution was *JUST* to remove a phpBB website with 80+ users.
I do not believe that the VPS could get this kind of loads.
Funny is that the VPS was "monitored" by them at the same time. They say the load spikes out for times to times in a matter of seconds.
This load is taken from the Parallels Infrastructure Panel or even the Node Panel, not from the VSP itself. Even when I'm logged in.
I've been a client for 6 month, and 2 of the last 3 constantly getting CPU hight usage. Strange is, that I come from a 512mb/25gb PowerVPS server to a 1GB/30GB server, with the *SAME* sites.
Anyway, the prupose of this topic is to:
- check if anyone had this problem (problem is: beeing sure that this load is IMPOSSIBLE to be created from yout service)
- recommend a decent VPS provider besides Future Hosting and PowerVPS.
From time to time my server's loads are going upto 900s.. And it becomes nearly same days each week. I've checked that backups and crons are disabled.

I get equal share from CPU plus it has got 384MB of memory? Why load is so high when I check in VPP......it is going in black and yellow zone in resources all the time?
It shows me following Parameters in QoS alerts
to know the load shown when doing a 'uptime' command is just for my VPS or the entire node?
what is the acceptable average load?
cos for mine, i see most the time is less than 1, but at times, for no particular reason that i know of, it can go up to between 5~10
Due to high IO load server is going crash once a day.
I have optimized the MySQL, Upgraded the kernel but still it's same. The SWAP seems normal.
Now probably it is due to high traffic of http or emails. How should I diagnose and fix it? I am in big trouble.

i've heart that xen can handle loads better than vz or openvz. is this right?

I want to have a fail over for my server. I was told that load balancing is the way to go.
Could anyone give me some instructions of what I would require. My primary server contains Cpanel.
the loads on my server is VERY HIGH and it needs to be upgraded fast.
I really have no clue as what to do... and i do not know any expert other than you people here - to help me out and put me on the right track.
i was thinking of
1) Getting a server with better CPU and more RAM
2) Load Balancing
However I know nothing of load balancing (other than how to spell it correctly )
1) Which of the above two options should i choose?
2) what are the extra costs in load balancing?
3) what should i know about load balancing before deciding?
4) How does load balancing work? I know there are two server - like one for database and one as webserver... but how does this work together?
5) what config should i be looking at in the two servers?
I'll stop here else i can go on and on and on...
I am giving the details of my server and service below, in case you guys need it.
We host a large number of small websites and are looking for high-availability and the ability to do maintenance on our application servers, so I'm looking for a load balancing solution. At this point, I'm considering Zeus ZXTM LB software, the Coyote Point e350si, and potentially an F5 1500 LTM.
The F5 solution is a total budget buster, and the Coyote Point UI is rough around the edges, but I've used them and they are reliable. Zeus looks like a winner with a great UI, but I haven't heard much about their reliability.
Bandwidth requirements are low at this point, so this is mostly about reliability and ease of configuration of a moderately complex set of services.
Any opinions on these vendors, or alternates I should consider?
I run a GSP (Game Server Provider) and i just baught 2 new octi xeon servers(Intel 5320)
i am having a problem with the load balancing, it dosen't balance de cpu usage on all cores but only on one, and it gets at about 80-85% and 3%CPU usage on the other one.
I was currious as to some suggestions you guys may have for setting up a load balanced website...
I would preffer it to be software based and free as I am just using this for some testing purposes.
I'm looking at load balancing a group of servers located at different data centers.
How feasible is this? Which options/solutions should I take a look at?
I would like to route using some sort of IP tunneling or similar so that the user doesn't see ww1.domain.com etc.
I will be distributing the load of the static/dynamic web pages, no database clustering.
I would prefer something a bit more intuitive than round robin. Perhaps directing incoming traffic based on existing server load etc.
Most of the load balancing solutions I've looked at assume all your servers are on the same local network.
I'm just curious, how many around here use load balancers in front of their webservers, and what kind of traffic do you push with them? (What kind of load balancer as well) Any other specifics would be nice as well.
Also, do you have failover for your load bal?
Hi. Can you please tell me how hardware load balancers work? I mean. What would i have to do to load a balance a site of mine?
Also what type of price range would i be looking at and what to look out for.
I'm really curious what makes the high end load balancer better than the low end ones.

My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)
