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.
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'm using a lot of load balancers in my workplace and I was wondering if there is a good open source one?
By good I mean one that can be used in an enterprise, and also is it efficient to use that software with regular PC?
BTW, I've been searching the internet a lot and found a few but not sure which one is better than the other one, I need your expertise.
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 ?
Say someone makes a http get/post request to api.example.com/a/b
Now say I have 10 servers setup as my backend servers. I want ha proxy to act as a load balancer and during the request handshake respond with:
apiX.example.com/a/b
where X is a number in the range 1..10
If haproxy isn't the right tool for this, what would you suggest?
What benefits to hardware based load balancers offer?
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 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.
I want to load balance + failover backup multiple vps webservers hosted on different providers.
I heard that for HAProxy you need multiple server under the same subnet, plus a shared (virtual) ip address between load balancers.
But it's not possible in my case cause every VPS is on different node/network.
Is there a way to use HAProxy in this kind of setup ?
