[Podcast] Message Ordering: Is it Cost Effective?
2008-01-02 00:01:00 In this podcast we’ll be discussing the issues around multi-threaded processing of messages by a service, specifically that the processing of message received second may be finished before that of the first. This scenario tends to rear its ugly head at higher levels of load and is critical for correctness in high-scalability environments. Our long time ... More About: Podcast , Cost , Message , Effective
WCF Everywhere? Not on my watch.
2007-12-29 16:00:00 The other day I was at Juval’s presentation where the main message was WCF is a better .NET. In other words, if you use WCF on every one of your classes, you’ll benefit. I don’t know about you, but I’m quite wary of silver bullets - they tend to inflict quite a bit of ... More About: Watch , Architecture , Performance , Development , Scalability

What Makes Smart Clients Safe?
2007-12-26 08:42:00 After my recent post on using AOP for smart client development, my partner-in-crime, Arnon, suggested I explain a little bit more on the whole issue of multi-threading in the UI. This isn’t going to be another tired explanation of how you should only update controls on the main thread. This is going to be ...

YAGNI - Once Bitten, Twice Shy?
2007-12-20 23:23:00 It?s one of the things that sometimes drives me mad about the YAGNI philosophy of Agile . We need to stop throwing out the baby with the bath water. Jay really liked that statement with relation to my previous post “Scalability - you wish you’re gonna need it“, so I thought I’d put up a logo ... More About: Architecture , Simplicity

ASP.NET Async pages and tasks now supported by nServiceBus
2007-12-19 00:57:00 I’ve been getting quite a few requests to support the asynchronous programming model exposed by ASP.NET 2.0 to enable the higher levels of scalability afforded by its IO completion ports. Well, nService Bus now supports it. You can find a sample in the “Samples” that demonstrates how to use PageAsyncTasks to complete work asynchronously. If you’re interested in ...

No more workflow for nServiceBus - please welcome the Saga
2007-12-17 12:42:00 As a part of my efforts to make clearer what place nService Bus has in the Microsoft .NET ecosystem, I’ve decided to retire the term “workflow”. Almost every conversation about nServiceBus where the term “workflow” was brought up, the reaction was almost identical: “What’s wrong with Workflow Foundation? Why aren’t you using it like you use ... More About: Saga

Web Service to NServiceBus Integration Sample
2007-12-16 23:18:00 After receiving numerous requests to see how to expose a synchronous web service that communicates asynchronously with other services via nService Bus, I’ve finally got a sample up. I’ve included a direct link here for convenience (webservicebridge.zip). In this sample, we have a service communicating over msmq, receiving a request message, and based on the value of the ...

Basic Request-Response sample for nServiceBus
2007-12-06 23:00:00 I’ve been getting more and more requests for tutorials and “getting started” stuff for nService Bus so the first one is now up on the Sourceforge site.

Object Builder - the place to fix system-wide threading bugs
2007-12-06 11:38:00 Last week I was at a client in their test lab and saw a strange bit of behavior. The system could be described as something like an air traffic control system, showing things moving around on a map. For just a second, a fraction of a second, one of the “planes” disappeared from the map ... More About: Architecture , Performance , System , Service , Scalability

[Podcast] Migrating from N-Tier to SOA
More articles from this author:2007-12-05 22:27:00 In this podcast we’ll be discussing certain methodologies for migrating an architecture from N-Tier to SOA. We’ll see what parts can be used almost unchanged, and which N-Tier concepts have no place in this new, service-oriented world. Ketan asks: Hello Udi, I am Ketan, working as Analyst Programmer in India. I want some information regarding SOA Architecture. I ... More About: Podcast , Web Services 1, 2, 3, 4, 5, 6, 7 |
