We are the Borg. Your messages have failed and will be assimilated. Resistance is futile. Distributed systems are a lot like Star Trek’s infamous Borg Collective: massively parallel, highly interconnected, and sometimes, drones services go down or are inaccessible. After all, even with a galaxy-class architecture, things sometimes go wrong. Messages can fail due to transient errors, unexpected exceptions, or configuration hiccups. However, well-designed distributed systems take a stronger c...| Particular Software
In distributed systems, coordination is hard—really hard—especially when both parties depend on mutual confirmation to proceed, but there’s no guarantee their messages will arrive. This classic dilemma is known as the Two Generals’ Problem. Like most problems in computer science, it’s easier to understand when explained with lasers, spaceships, and sarcastic smugglers. Let’s set the stage: It’s Return of the Jedi and the second Death Star looms large over the forest moon of Endo...| Particular Software
It doesn’t matter if you’re developing using MVC, WebAPI, or Razor pages—you want your controller code to be nice and lean. The more bloated that code is, the more coupling you have, and the closer you are to an unmanageable big ball of mud. You probably already know that, but I’d bet not all of your controller code is as lean as you’d like it to be. Is it? So that leaves the question… How do we get there?| Particular Software
Every software system evolves through different stages of complexity. They start simple—attempting to solve a problem that might not yet be well-defined. As they grow, problems become more well-defined, and then they grow some more. Just like with lanky teenagers, this growth can sometimes cause growing pains. A skilled architect knows how to watch for the signs of these growing pains and how to apply more robust architectural patterns to ensure the system can continue to grow and flourish....| Particular Software
Migrating a message-based system from on-premises to the cloud is a colossal undertaking. If you search for “how to migrate to the cloud”, there are reams of articles that encourage you to understand your system, evaluate cloud providers, choose the right messaging service, and manage security and compliance. Curiously, what’s often missing from the discussion is details, like how to handle all the other on-prem systems that integrate with your system, both upstream and downstream, that...| Particular Software
We all love building greenfield projects. 1 But inevitably, starting a new project involves lots of meetings with business stakeholders to hash out initial requirements and canonical data models. Those are…not so fun. When one of those meetings occurs after a carb-heavy lunch, it’s easy for your mind to drift away…back to those university lectures about entity design. Think of the nouns and what attributes they have. A dog and a cat are both animals and have 4 legs. Except now it’s Cu...| Particular Software
When code breaks, our first move is carefully inspecting the call stack. It helps us find the needle in the haystack by understanding how, where, and why the failure occurred, including how we got there. However, in a message-based system, we no longer have a single call stack. We’ve exchanged it for a haystack of call stacks, which makes finding the needle (the root cause of the failure) even more difficult.| Particular Software
You’re standing in the airport, waiting to pick up your bag. Did you ever stop to think about all the software systems involved in tracking your luggage on your journey? From the moment you drop it off at your departure airport to the moment you breathe that sigh of relief as it shows up on the baggage carousel is a complex story of messaging and system integrations. I recently had the opportunity to chat with the lead developer for the luggage arrival system at a major Asian international ...| Particular Software
NServiceBus endpoints have always been good at running reliably, but they could have been better at stopping. And when you want an endpoint to stop, you want it to stop…now. In NServiceBus 8.0, which is now available, we have introduced support for cooperative cancellation, which will give you greater control over how an NServiceBus endpoint behaves when you need to shut it down. Let’s talk about what cancellation is, how it relates to NServiceBus, and how we’re delivering cancellation ...| Particular Software
Because it’s hard to write idempotent code effectively, NServiceBus provides the outbox feature to make your business data transaction and any sent or received messages atomic. That way, you don’t get any ghost messages or zombie records polluting your system. 1 But the outbox can only be used inside a message handler. What about web applications and APIs? With the new NServiceBus.TransactionalSession package, you can use the outbox pattern outside of a message handler too.| Particular Software
The NServiceBus messaging pipeline strives to achieve the right balance of flexibility, maintainability, and wicked fast…ummm…ability. It needs to be wicked fast because it is executed at scale. For our purposes, “at scale” means that throughout the lifetime of an NServiceBus endpoint, the message pipeline will be executed hundreds, even thousands of times per second under high load scenarios. Previously, we were able to achieve 10X faster pipeline execution and a 94% reduction in Gen...| Particular Software
We get a lot of questions about Kafka. Is it good? Does it live up to the hype? And most frequently, when are we going to support Kafka in NServiceBus. But to fully answer these questions, it’s essential to understand what Kafka is, and more importantly what it isn’t, and then think about the kinds of problems that Kafka solves. So, let’s dive into the (heavily footnoted) details…| Particular Software
The Particular Service Platform is packed full of features that help you monitor your NServiceBus systems. Among other things, it enables you to: manage messages that require a manual retry see when endpoints go offline and back online detect connectivity problems with databases, brokers, and other systems using custom checks troubleshoot message processing performance, both per-message and across an entire flow, using ServiceInsight Many of these capabilities have been developed over time as...| Particular Software
The key to a successful Cosmos DB system is its data partitioning strategy. Like the rows of shrubs in a hedge maze, the logical partitions that divide data must be carefully planned, because that affects the scalability of the system and defines the boundaries for logical transactions. In version 1.1 of our CosmosDB persistence package, we’ve made defining the partition key for each message processed by NServiceBus much more straightforward, without needing a custom pipeline behavior. We...| Particular Software
Sagas are one of the most powerful tools available in the NServiceBus toolbox. With a saga, a business process that would otherwise have been implemented as a clunky batch job 1 can be built in a much more elegant and real-time manner. We’ve focused on supercharging your ability to develop NServiceBus sagas in our latest round of releases. As a result, you’re going to feel like you’ve got your own “heads-up display” when developing sagas. We’ll give you suggestions and point out p...| Particular Software
One of the greatest ever contributions to video games was the invention of the pause button. There are some sequences—those that require absolute perfect timing—where your repeated failure can make you so frustrated you just need to pause, walk away, and try again later until you get it right.| Particular Software
Sometimes developers only care about speed. Ignoring all the other advantages messaging has, they’ll ask us the following question: “But isn’t RPC faster than messaging?” In place of RPC, 1 they may substitute a different term or technology like REST, microservices, gRPC, WCF, Java RMI, etc. However, no matter the specific word used, the meaning is the same: remote method calls over HTTP. So we’ll just use “RPC” for short. Some will claim that any type of RPC communication ends ...| Particular Software
Do you think Azure Functions are pretty great? Us too! Do you hate boilerplate code? Yeah, us too. Have you heard of C# source generators 1 and thought they sounded pretty cool but didn’t really know how they could be useful? In the newest version of our Azure Functions integration, we’ve used source generators to reduce the boilerplate needed to set up an NServiceBus endpoint on Azure Service Bus down to just a few lines of code.| Particular Software
