  • Use network load balancers (LVS, IPVS) for scaling
  • Compare prices and beware of vendor lock-in
  • For TLS: use HAProxy for fast frontend, Envoy for compatibility
  • Caching: Varnish, Apache Traffic Server for large content
  • Prefer open-source stacks and database caches (e.g. Memcached)
  • Use message queues and buffers for workload smoothing
