Configure Proxmox high availability (HA) for VMs
Make Proxmox VMs restart automatically on another node when a host fails: cluster and shared storage requirements, fencing, HA groups, adding resources and testing failover.
DNS failover between servers or clouds explained
How DNS failover works with health checks and low TTLs, how it compares with floating IPs and load balancers, setting it up across two servers or providers, and its limits.
Floating IP failover between two servers with keepalived
Use keepalived and VRRP to move a shared virtual IP between two Linux servers or VMs automatically, with health checks for Nginx or HAProxy, and know when provider APIs are needed.
Server high availability basics: redundancy, failover and clustering
What high availability means for servers, single points of failure, active-passive vs active-active, floating IPs with keepalived, database replication and when HA is worth the cost.
