TravelSmart is one of the world’s largest online travel services provider with millions of interactions daily.
Users can search the TravelSmart database with custom queries. When a user submits a request at their HTTP web
service interface, backend services query that from thier database and provide the requested results. Since
they have a very large database with thousands of online users, they need to have a proper way to respond to
Since TravelSmart need to handle millions of requests daily, they decided to introduce an ESB as the bridge
between their backend db services and the database.
Each request coming from the web interface will go through UltraESB-X and now ESB is responsible of
handling queries efficiently. UltraESB-X will cache each successful response with a hash key generated from
the incoming payload. When the same request comes for the second time, instead of querying the TravelSmart
database, ESB will send the previously cached response.
