networkingConfigure HAProxy with Consul for dynamic service discovery and automatic backend updates
Build a self-updating load balancer by integrating HAProxy with Consul service discovery, consul-template, and health checks so backends register and deregister automatically without manual reloads.
Implement Istio multi-cluster canary deployments and traffic splitting
Build a primary-remote Istio multi-cluster mesh with shared trust domain, then run progressive canary rollouts using DestinationRule subsets, weighted VirtualServices and metrics-based promotion across clusters.
Configure PostgreSQL 17 SSL encryption and certificate-based authentication
Set up a private CA, issue server and client certificates, enforce TLS 1.2+ with strong ciphers, and configure pg_hba.conf for mutual TLS client certificate authentication in PostgreSQL 17.
Set up HAProxy SSL termination with Let's Encrypt certificates
Learn how to terminate SSL/TLS at HAProxy using Let's Encrypt certificates, redirect HTTP to HTTPS, automate renewal with deploy hooks, and harden your cipher suites for production load balancing.
Configure HAProxy with Consul for dynamic service discovery
Learn how to combine HAProxy, Consul and consul-template to build a self-updating load balancer that discovers backends automatically, reacts to health checks, and reloads without downtime.
Configure PostgreSQL 17 connection pooling with PgBouncer for high availability
Deploy PgBouncer in front of PostgreSQL 17 with session, transaction and statement pooling modes, SCRAM-SHA-256 authentication, keepalived-based HA, and Prometheus monitoring for production workloads.
