Application Servers

PreviousClientsNextDatabases

Last updated 2 years ago

Stateless App server

  • All servers don’t remember client sessions

    • Using server-side cache like Redis

    • Using self contained data coming with the request such as tokens payload, headers, request payload...

Stateful App Server

  • Remember user sessions

    • Hash table (or any other cache data structure) to remember which app server to routes to

    • Sticky sessions

    • More difficult to scale
