Er Apache Camel riktig valg for deg? Lytt til erfarne Camel spotters.

Editor's Notes

  1. Hva har kompisen til mikael palin med camel spotting å gjøre?Om oss:Vi er nok en bedrift som er litt mer opptatt av transaksjonell sikkerhet enn andre...
  2. For mye tekst
  3. For mye tekst
  4. For mye tekst
  5. Rollback funker, men kun på en og en transaksjon.
  6. Felles begrepsapparat => felles design og arkitektur?
  7. Overdrevet kompleks og lang rute i stedet for en enkelt service som opererer direkte mot database?Choice when mrf filter til å hente inn filer med et suffix i stedet for file.listfile(.txt)..
  8. Ja, hvorfor ikke? Du trenger ikke basere hele designet ditt på camel selv om du tar det i bruk.Særlig om du ikke har noe særlig eget allerede for integrasjon, og kanskje manglende erfaring med integrasjon?Men du må fortsatt forvente å bruke meste parten av tiden på å forstå hva som skjer inni camel, antagelig nok tid til at du godt kunne skrevet alt selv, men det hadde ikke blitt noe bedre!Hvis du er som oss veldig opptatt av transaksjoner vil du måtte gjøre en hel del for å få camel ruta di sikker, men dersom du lager applikasjoner som gjør veldig mye integrasjon, og hvor hver melding kanskje ikke har så høy verdi og krav til sikkerhet så vil du kunne få det mye enklere...
  9. Spring integration, mule, roll your own?

  11. MainframeJava – stay etc..
  12. Aktivt community, satsing på lettvektsutvikling.. Mange store bpel orienterte rammeverk etc...
  13. Camel har utrolig mye kraft i lite og konsis kode. Alt blir veldig enkelt, men det er veldig lett å trå feil!
