We have WebLogic installed on two separate RHEL 5.6 servers. An Apache web server instance will be installed on each of those servers which will be configured to listen on 80 and 443 and redirect any requests from 80 to 443. SSL will terminate at the Apache web server and traffic between the Apache web server and the WebLogic servers will not need to be encrypted.
I have one major domain but the server spec behind it is not good enough. Hence I want to relay the traffic, in particular php-mysql queries to multiple smaller servers. How is that normally be done?
(BTW I wonder how much traffic or number of php/mysql request a normal setup on ec2 micro instance can handle? )
I did have a look of EC2 load balancer.
I want to configure Haproxy for outgoing mail load balancing.
my configuration file /etc/haproxy.cfg is.
global
maxconn 4096 # Total Max Connections. This is dependent on ulimit
daemon
nbproc 4 # Number of processing cores.
Please correct me, but my understanding is that with software load balancing a service must be run on each server while there is one DS that notifies the other servers that a server has gone down and that they should consume that servers load.
With hardware load balancing what happens in a fail-over? Could someone explain?
We have a SQL Server 2008 R2 (10.5) on a dedicated box with a single 2.4Ghz processor, which regularly runs at 70-80% CPU.
I have been reading many posts on serverfault as well as on other sites regarding all these.
What I understand is, Multiple A records(round-robin dns) can be used for both :
Load sharing (round-robin, but NOT load-balancing).
We use Varnish as our front-end web cache and load balancer, so we have a Linux server in our development environment, running Varnish with some basic caching and load-balancing rules across a pair of Windows 2008 IIS web servers.
We have a wildcard DNS rule that points *.development at this Varnish box, so we can browse http://www.mysite.com.development, http://www.othersite.com.development, etc
I have heard people say "oh that server is off the load balancer so you can run that expensive script on it".
What implications does a server off the load balancer have? Fundamental to answering this, I understand load balancing, but I don't know what the dynamics of a system with 5 servers (4 on the load balancer) has.
Thanks
Does anyone know of any Windows software that will do forward-proxying load-balancing, like HAProxy does? There are tons of reverse-proxy solutions, but I can't find any that do what HAProxy does, that is, allows you to load-balance a group of forwarding-proxies. I have a proxy farm (don't ask) that I need to round-robin balance. HAProxy will do it, but is very unstable on Windows. Thoughts?
