Subject: RE: Asynchronous message queue by SMTP&POP3 Whether you need asynchronous messaging, queuing, and guaranteed delivery depends on in part on the nature of your application. Some people are looking at XML for mission-critical (bet-your-business) applications. > Some of the advantages and particular features: > o almost guaranteed delivery or notification of failure That's workable for many applications -- for example delivering news articles to a browser or a class schedule to a university student. If there is a delivery failure, I can always read it later. > Disadvantages: > o no server programming model - how does one program a java service at > orchard@p...? > o not strong enough reliable delivery These are a problem if you want to use an XML infrastructure for mission-critical applications. For example, a major auto company processes many gigabytes of EDI transactions daily and there is a lot of momentum for moving to XML/EDI. You can't let $200 million in parts orders fall into the bit bucket. You'll need to do load balancing and custom document handling to get adequate performance with that type of application.
