Load Balancing with Piranha for Luminis 5

Submitted by mcshell on Tue, 11/05/2013 - 10:25

Hello All,

I was wondering if any one was using Piranha for load balancing for Luminis 5 or if you use it in Luminis 4. We are currently looking to implement Luminis 5 and will need to move into the realm of load balancing and just trying to see if this would be a viable solution or to look else where.

Thanks,
Mike

Luminis Version:

Mike,

While I am not familiar with Piranha I have worked with several sites that run Luminis behind a variety of different load balancers. F5 seems to be a popular hardware option but I do work with people who utilize software load balancing solutions as well.

Do you currently use Piranha for any of your PROD systems?

I believe the load balancer requirements for LP 5 are basically the same as LP 4 which is mainly just support for 'sticky sessions'.

I hope that helps! Someone else may be able to elaborate more on their specific installation.

Thanks,
Tom

Tom,

Currently we do not use Piranha to load balance any of our prod systems. What other software packages are other schools using to load balance? We have looked at F5 3900 series as a option.

Thanks,
Mike

Mike,

I have heard of a few different software options but the one I've seen recently used successfully is HAProxy. For hardware load balancers I have also worked with Cisco ACE and an A10 load balancer but I'm not sure which A10 model.

As I mentioned previously, just about any current load balancer should be able to do the job. The main functionality that you want to make sure you can support is session stickiness.

Good luck with your evaluation!

Tom

Tom,

The college that went with HAProxy did they implement this for Luminis 5.0.4 or 5.1? From reading about it, it looks promising.

Do you happen to know the specs of the server that they are running it on? From the reading it appears a low/medium grade server would work.

Thanks,
Mike

We've been happy with our F5 Big IP load balancers for Luminis IV. We plan on using them with LP5 also. They also balance our Banner INB, and a few other services.

The F5's are more like big applications. Like this one "module" of an F5 can talk SAML for access control to apps http://www.f5.com/products/big-ip/big-ip-access-policy-manager/specs/

The management gui is pretty slick, and we've had zero downtime due to the F5's since we bought them. About.. hmm, maybe 4-5 years ago.

The downside is cost. Fairly expensive.

Jason,

The F5 load balancer you are using, would you mind letting me know what series it is? We looked at the 3900 series but you are right they are kinda expensive.

3600. The smallest one they made at the time. Even at peak registration times we barely use any of its resources. That is about 5000 concurrent sessions from our Portal, and I have no idea how many from INB, but not much.. few hundred more maybe.

We ended up buying three total. Two of them teamed for fail over in production, and one for testing.

Jason,

That is great to hear that you have had no issues with the F5 load balancers.

Thanks,
Mike

Mike,

I don't see why Piranha wouldn't work for you.

We use Apache httpd in a reverse-proxy configuration to load balance between two Luminis 5 nodes. Happy to share the config if you're interested.

Nick,

That would be great to see the config you are using. My email is mcshell at edison dot edu.

Thanks,
