SOA Patterns is “deal of the day” on Manning’s site (Apr. 14th)
I just got a notice from Manning that my book SOA patterns will be featured as “deal of the day” on Apr 14th – that means that it will be available for 50% off starting Midnight US ET of April 14th (and considering it’s a world-wide offer it would actually last for more than 24 hours).
To get the 50% discount use code dotd0414au at www.manning.com/rotem
If you’re not familiar with my book (which I guess is unlikely if you’re reading my blog, but anyway), you might want to check out the SOA Patterns page on my site, read one or more of the pattern draft or check out the book reviews.

The Saga pattern and that architecture vs. design thing
It has been few months since SOA Patterns was published and so far the book sold somewhere between 2K-3K copies which I guess is not bad for an unknown author – so first off, thanks to all of you who bought a copy (by the way, if you found the book useful I’d be grateful if you could also rate it on Amazon so that others would know about it too)
I know at least a few of you actually read the book as from time to time I get questions about it :). Not all the questions are interesting to “the general public” but some are. One interesting question I got is about the so called “Canonical schema pattern“. I have a post in the making (for too long now,sorry about that Bill) that explains why I don’t consider it … Read More »
SOA Patterns : Composite Frontend
I am not blogging much these days – most of it is due to trying to get my bloody book finished. A case study and a finished anti-pattern chapter where recently pushed to the MEAP, and here’s one additional pattern from chapter 6 (service consumer patterns):
When we try to think about service consumers, the obvious candidates are, of course, other services. Nevertheless there are other software components that interact with services e.g. legacy systems, Non-SOA external systems or reporting databases. The Composite Frontend pattern deals with yet another type of service consumer – the User interface.
First let just verify that User interfaces aren’t in fact services. One reason user interfaces are not services is that they converge several business areas e.g. if you want to enter an order you’d probably also want to lookup information about the customer, maybe you’d … Read More »
SOA Patterns short status update
First off, In the previous post I published the Transactional Integration anti-pattern – if you need it for off-line reading you can also get it in PDF form.
I am currently writing the “3-tier SOA” anti-pattern and it seems that together with “Whitebox services” anti-pattern it will complete the anti-patterns chapter. The two other anti-patterns in the chapter are Nanoservices and the Knot
I’ve also started writing the composite-front end pattern (e.g. portals, prism etc.) but mid-way I thought about it and stopped. I basically realized that there are a few patterns that are pretty common to SOA on one hand, but you are much more likely to use a 3rd party solution that includes them than to realize them yourself. These include the composite front-end mentioned above, repository, orchestration, servicebus, service host that appears in chapter 2 (though I think that is marginal … Read More »
