Scalable Architecture

architecture

  • Scaler :
    • front end.
    • load balancers
    • web caching/ squid
    • connection pooling to Apache/Web Server machines
    • mark down/up machines
  • Web Server
    • Apache or lighttpd
  • Distributed Databases or XXXX
    • might have a grid network here that is specialized to serve specail needs besides the generic databases. Example - CDNs (content delivery networks).
    • each web server does NOT necessarialy connect to all databases.
    • Can have caching before database / networks....example memcached.
