Part 2 - Where are the travel agents

[E. Messing]

Hi all
I have just realized that from the assignment text I couldn't tell where are the travel-agents : Out there on the net, using the internet to communicate with FBN (FireWalls etc) , or in the company - using the intranet to communicate (no Firewall).
What was you assumption?
thanks

[Ajith Kallambella]

Does it matter? I guess not. These days most enterprise architectures assume that the users are either in a DMZ or outside the firewall. Ensure you accomodate both these scenarios in your technical architecture and you'll be fine.
Hint : HTTP server in front of the web server and a Single sign-on

[E. Messing]

Well - it does matter when you think wether the Agents application will connect to the WEB-tier or the EJB-tier.
And about the hint : didnt get it . Web-Servers are HTTP servers...

[Denis Wang]

Since the 3270 terminals have to be thrown away, I prefer travel agents similar to web customers using browsers to connect to web servers through http/https.

[Denis Wang]

it is totally a valid assumption that, travel agents are centralized within the intranet for performance consideration.
if you assumed the other way, special security consideration is demanded.
Thank you very much for your thoughtful post.

Travel agents communicate with backend services via the intranet is a good assumption,for the original system communicate with server via dedicated line.And using J2EE,the presentation tier of travel agents is java client application,you can use http/https or also TCP/IP make a connection to backend service.
By the way,does we need consider there is email server for Transmaster,otherwise how they will send email to customer?

[E. Messing]

HI Jacky
I guess the email will be sent from FBN not the CC authorization system.

[Jacky Doner]

E. Messing,
I think you are right,but I think we should assume there is E-mail server subsystem in FBN.

There is word:" Our travel agents Java application must be able to access the system and we want our customers to have access throught the internet."
So Travel agent ---- Java application---> SW???
