Does anyone remember the times when hardware was more expensive than software? The purpose of the multi-tenancy option is to save hardware resources like CPU, RAM and disk. The price of those hardware resources is much, much lower than the price of multi-tenancy option itself. Let me demonstrate:

The price of a PC with Intel I7 CPU, 32GB of RAM, low end graphic card and two 2TB disks is around $1.5k. Intel I7 is an 8-core CPU. The price of Oracle EE (CPU license) for that PC is $80k. If I run two instances of Oracle on that PC, I will likely use 2GB RAM and 1 core on overhead alone. PDB option can save me from such wasting of resources - for $80k. If we take the more expensive large Dell pc with 4 CPU sockets and 512GB RAM, the price is higher, about $7k Multi-tenancy option, assuming CPU license, will be for 32 cores. List price says that it will cost $320k. And it will save me resources on $7k PC. You are right. It's sad.
