Consul Infrastructure Recipes
Preetha Appan, Consul Expert at HashiCorp This talk covers several specific infrastructure and distributed systems problems, and how to use Consul to solve them. Use cases include: • Load balancing across service instances • Running active/passive instances that fail over without operator intervention using locks • Transparent data-center failover during outages using prepared queries • Turning experimental features on/off for a subset of application servers using the KV store • Integrating Consul with existing applications using consul-template -- If you liked this video and want to see more from HashiCorp, subscribe to our channel: https://www.youtube.com/c/HashiCorp?sub_confirmation=1 To learn more, visit our hands-on interactive lab environment, HashiCorp Learn: https://learn.hashicorp.com/ HashiCorp is the leader in multi-cloud infrastructure automation software.
