High-availability architectures are critical for business intelligence tools that require continuous uptime. This article explores a production setup using Keepalived for virtual IP management and Nginx as a reverse proxy to achieve automatic failover. The design ensures that if the primary server fails, traffic is seamlessly redirected to a standby server. Key components include health checks, VRRP configuration, and Nginx upstream management. This pattern is widely applicable beyond BI tools, making it a valuable reference for any service requiring high availability.
