I make a new stack, new VMs, new loadbalancer and just update dns record of the service from old stack to new. Thats blue-green. Rolling is trickier, but still

Rolling is trickier, but still, native cloud solutions do not use service discovery, imho.
- jordanbeiber 5y agoWhat you’re describing took place with on-prem iron as well - nothing cloud about it. At all. Service discovery is in part DNS with low ttl, but there’s a part of it that ties in to configuration management, monitoring and observability as well. If you “update dns” that means you’re doing a part of what consul does (only f ex nomad does it for you). Nothing magic, but you still “need it”. Tags and metadata is a large part of it though, as well as configuring things automatically based on state of the SD and K/V. In the end - whatever works, I guess.
