Hi

Can someone help me understand what is the negative impact on reliability when a cluster a web servers are replaced with a a single web server in a 3 tier architecture and how?

When you have a single middle tier (web tier or business tier), hence you have a single point of fail. As if your tier fail all system fail.
It implicate in availability, so the system is less readable.

Hi Mateus Brum,

I think you mean to say, "less reliable" ?

Best regards,
