E3 is not a server SKU, it's meant for workstations and it's more similar to i7 than E5. It lacks various features including ECC RAM which, I suppose, is a no-starter for cloud hosting. Also some virtualization capabilities are missing, notably accelerated interrupt injection (APICv+posted interrupts).
