Thanks Gordon, and Sandy. With RabbitMQ if a message is silently dropped by the broker will a timeout still occur/exception be raised because no reply/ack was received? With the QPID driver the automatic ack()'s Sandy mentioned don't occur? Will the sender eventually become aware that a message

[Openstack] lbaas members IPs vs instances

2014-07-15 Thread Aaron Knister
Hi, I just went to add a new member to an LBaaS pool in neutron and noticed something that seemed strange to me-- one adds an IP address to the LBaaS pool vs an OpenStack instance. This is in contrast to AWS where you do add instances to ELB pools, not raw IP addresses. To me the benefit to
