I am running several EC2 instances behind load balancers.
Can I insert my SSL certificate into Apache server without insert my cert into the load balancers?
How should I set for the load balancers? Change the rules of security groups or something else? Thanks!
We're building a load balanced setup with two load balancers (that also terminate SSL) and several upstream servers. Both the load balancers and the upstream servers run nginx. The network on which requests are forwarded to the upstream servers cannot be trusted, hence we have to re-encrypt it after SSL termination on the load balancer.
I'm planning to add a hardware load balancer, but I'm not sure if adding one will cause me to lose the ability to restrict traffic by IP ( on folder level by using allow and deny in apache configuration)?
Do you use hardware load balancers to shift traffic with client IP or load balancer IP ?
Our infrastructure consists of load balancers running HAProxy and Apache, which forward traffic to our app servers running just Apache. The past few days, we've been seeing connection floods which the load balancers happily pass along, but the connections quickly overwhelm our application servers.
I am tasked with setting up redundancy on two load balancers (using Haproxy & Keepalived). The idea is that we will have a load balancer managing our site but we need that load balancer to have a backup.
I am having trouble pinging a load balancer server through a VPN. I'm using keepalived for a failover to keep the load balancers redundant.
What are some load balancers that has this algorithm (Minimum Expected Delay or Shortest Expected Delay)?
Are there any theoretical studies that might support this algorithm like equations for the delays between users to the NLB and to its server farm?
P.S. I'm trying to make a simulation tool for network load balancers..
In the case that we buy a range of IPs at RIPE. Is there any way to assign those IPs to Amazon EC2 instances or load balancers?
PS: I know that OnApp providers can do it
I am using Haproxy to load balance replicated mysql master servers. I am also using Heartbeat and Pacemaker for Active/Active ip failover with two virtual ips on the two load balancers for web server high availability. I used location in pacemaker to stay VIPs one on each load balancer and I'm using round-robin DNS domains pointing to VIPs to load balance the load balancers.
I'm working on design of enviroment for enterprise application. There is plan to host application in one Hyper-V server in several VMs.
Host server has limited CPU and memory capacity, disrtributed between VMs.
Is it good idea to use load balancers in order to improve perfromance of VM servers hosted in Hyper-V enviroment or much better to allow to use more resources to VMs?
