Is it possible to share SSL certificates across servers?

Question

We have a web application we will be launching soonish and for right now we just have one SSL/HTTPS certificate. We have this one certificate shared across 3 servers(in a cluster for load balancing) which we've been told is "not the right way"...

So do you always have to buy N certificates for N servers or is there a special "shared" certificate or such? Why is it not right to share the certificate when these 3 servers are exactly the same hardware and software?

Have a look at this question:
