HAProxy + Consul vs VulcanD + EtcD

HAProxy/Consul

• Pro: Both are production ready
• Pro: Can handle any throughput we will see
• Pro: More feature rich
  1. Healthchecks
  2. DNS and HTTP API available to map endpoints
  3. Lots of service discovery built in
• Pro: Solution could be used in more than one place (bld/prod/etc..)
