Synchronous RESTful communication between Microservices is an anti-pattern ... you seem to being saying that the Netflix architecture (hystrix, eureka, ribbon, ..) is broken ... hmm what would @benjchristensen say?

iscsi and iBFT test using qemu/kvm and ipxe

The general goal of this doc is to show how to use qemu, ipxe and tgt to test iscsi and iBFT.

There are loads of things that could be done to make this test environment. But for now, it just shows a simple case to show parameters necessary.

Setting up iscsi test environment

In examples here, the iscsi server is available at 192.168.1.10. The qemu host system is available at 192.168.1.11. We assume port 9999 is available to run a python simple web server.
