Load Balancing



Does anyone of you have tips regarding Load Balancing an EPiServer-solution, or load balancing in general? We are building a website that occasionally will have a pretty big load. We are thinking about, in these occasions, scaling up the solution with a second front-end webserver, using only one database server. Does this sound reasonable or is there a better way? Is Microsoft NLB a good enough tool for "spreading out the requests" on the two servers or which one do you recommend? After reading on EPiServer World I understand that when scaling up a solution we have to consider synchronization of the cache between the servers. Is that easy to set up and does it work? Any other things we have to consider?

Thank you!

There are lots of customers running load-balancing with two or more web servers and a database behind. But the one I talked to (including our own hosting) say the same thing: Avoid NLB if possible, use a hardware load-balancer instead that understands HTTP traffic.

Load balancing is really scale-out, you can also do scale-up by investing in multi-processor machines which also give you a good performace boost.
