April 30: We have established proof-of-concept installs and are nearing 4.17 branching, with the possibility of Azure landing as Tech Preview. It is a good time to capture known outstanding work so we can work toward planning a 4.17 GA.   Outbound Access: poc uses an outbound load balancer to provide egress to control plane nodes. Keeping a third load balancer around for egress is unnecessary, so we should be able to handle this more efficiently. Need to add Bootstrap node public IP for SSH access. We will also need to delete the SSH security rule on bootstrap destroy. Captured in CORS-3302 Machine Provisioning is too slow. Recently a 15 minute timeout was added to each CAPI provisioning period. Apparently the Azure machines are far exceeding this timeout. We need to debug why machines are taking so long to provision. Need to make image creation concurrent (or remove the need altogether). Currently uploading the image and creating resources takes ~11 minutes, which isn't terrible, but is  noticeably slow as it blocks other progress. We should try to make this less noticeably slow. Compute nodes are using nat gateways for outbound access. This may not be desirable from a cost perspective, and we should allow this to be disabled if possible. May require upstream work. This may be captured by CORS-3074 We need to support multiple IPs per load balancer a la ARO: RFE-4561
