  • What they don't tell you about migrating a message-based system to the cloud

    Written by Kyle Baley on September 12, 2023

    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 can’t be upgraded at the same time. This gets even more tricky when those integrations are over on-prem-only technologies, like MSMQ, that don’t integrate out-of-the-box with cloud alternatives like Azure Service Bus or Amazon SQS. It’s as if they’re saying, “Have you documented your system? Great! Have you chosen a cloud provider? Awesome! Do you have all the services in place? Wonderful! Now go rewrite all your code… we’ll wait…are you done yet?..What are you looking at me for? I’ve already told you to plan carefully, I can’t do EVERYTHING for you”

  • More powerful Cosmos DB persistence

    Written by Bob Langley, Daniel Marbach, and Aleksandr Samila on June 21, 2022

    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’ve also added pessimistic concurrency support for more reliable processing of sagas with high contention patterns.

    1. Maybe a little too powerful in this case, as there's a risk that the behavior for identifying the Cosmos DB partition could break the outbox feature.

    2. Unless you want to.

  • What's new with NServiceBus and Azure Functions

    Written by Hadi Eskandari, Mike Minutillo, Sean Feldman, and Tim Bussmann on August 31, 2021

    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.

    1. A source generator is a new type of Roslyn analyzer that runs during compilation, inspects the code you're building, and produces additional source files that are compiled together with the rest of your code. Check out the blog post introducing source generators or the Microsoft source generator docs for more info.

  • Cosmos DB Persistence — Questions & Answers

    Written by Adam Ralph, Dan Kent, and David Boike on August 17, 2021

    We recently released NServiceBus.Persistence.CosmosDB version 1.0, which provides saga and outbox storage for NServiceBus endpoints that is transactionally consistent with the business data you store in Cosmos DB.

    This component was previously offered as a preview package. Now that it has reached version 1.0, our full support policy applies, including API stability and backporting of bugfixes.

    Now that our Cosmos DB persistence has reached general availability, let’s answer some common questions about Cosmos DB and what it means to use Cosmos DB with NServiceBus.

    1. For reference, in one year, that's 5 minutes 16 seconds of downtime.

    2. A noisy neighbor problem is where one tenant in a multi-tenant hosting scenario monopolizes too many of the resources such that performance is impacted for the other tenants sharing the same resources.

    3. Data committed to the database but without an accompanying message sent out due to a failure between the database commit and message send operations. See What does idempotence mean? for more details.

    4. A message sent before a failure occurs that can't be recalled, so the message refers to data that never got saved to the database. See What does idempotence mean? for more details.

    5. The two package names are NServiceBus.Persistence.AzureStorage and NServiceBus.Persistence.AzureTable. They're the same thing, we just renamed the package between versions 2 and 3 to make it more clear what it does.

  • NServiceBus with Azure Functions turns 1.0

    Written by Sean Feldman and Yves Goeleven on April 27, 2021

    NServiceBus support for Microsoft Azure Functions, previously available as a preview package, is turning the big 1.0 and is now generally available.

    Over the past nine months, we’ve been offering NServiceBus support for Microsoft Azure Functions as a Preview. This marked the first in a series of previews designed to provide new capabilities to the Particular Software Platform and explore new options for NServiceBus customers.

    Now we’re adding Version 1.0 to its credentials, which means that in addition to production support, we’re also committing to all aspects of our support policy, including API stability and backporting of bug fixes. Plus we added a few more features, so you can do a lot more with Functions too.

    Let’s take a look.

  • Azure Storage Queues learns some new tricks

    Written by Aleksandr Samila, Daniel Marbach, Sean Feldman, and Yves Goeleven on April 13, 2021
    Azure Storage Queues is a basic yet robust queueing service available on the Azure platform. In contrast to other messaging services in Azure, it has very few features out of the box. For example, it lacks concepts like topics and subscriptions to build publisher and subscriber topologies—these are capabilities NServiceBus adds on top of Azure Storage Queues. In our latest enhancement release, we’ve added native publish/subscribe to our Azure Storage Queues transport, creating feature parity between Azure Storage Queues and… Read more

  • Transactions with Azure Table Persistence

    Written by Daniel Marbach and Laila Bougria on December 8, 2020
    One of the major changes that have permeated organizations across the globe in the last decade is the use of cloud providers and the variety of services they offer. For data storage alone, Azure offers: Table Storage, CosmosDB, SQL Server, Blob Storage, and more. There are, of course, many advantages to these cloud services, like minimizing infrastructure management, and higher performance at a reasonable cost and it’s easy to accept these advantages in the face of the trade-offs, like giving… Read more

  • Support for Azure Functions

    Written by Sean Feldman and Bob Langley on August 19, 2020

    Update: NServiceBus hosting with Azure Functions for Azure Service Bus is now 1.0. In addition to full production support, that means API stability and backporting of bugfixes. See our release announcement here.

    Microsoft Azure Functions provide a simple way to run your code in the Azure Cloud. They are easy to deploy, scale automatically, and provide many out-of-the-box ways to trigger your code. Rather than pay for an entire virtual machine, you only pay for compute while your code is being executed.

    NServiceBus makes Azure Functions even better. You can use a simple but powerful API to consume and dispatch messages, add robust reliability features like delayed retries, an extensible message processing pipeline, and a suite of tools to help you monitor and maintain your message-driven system. We think they go together like milk and cookies.

  • The end of the legacy Azure Service Bus transport

    Written by Kyle Baley on June 30, 2020

    A while back, we introduced a brand new transport for use with Azure Service Bus. This transport was a necessary step in our Azure offering to allow users to target .NET Standard and .NET Core. It also used the new Microsoft.Azure.ServiceBus client rather than the older, deprecated client.

    More importantly, it started the process of deprecating the now-legacy Azure Service Bus transport. At the time, we didn’t have details about how we would do that; now we do.

  • Getting NServiceBus ready for the cloud

    Written by Anne Epstein on June 2, 2020

    More and more companies are realizing that it’s in their best interest to move to the cloud. As software consultants at Headspring, we’re often tasked with helping organizations migrate their highly complex legacy systems to modern cloud environments. For clients using NServiceBus to facilitate messaging, moving to the cloud without it seems untenable. So how do we prepare to take NServiceBus with us?

    For complex software systems like the ones we’re used to working with, moving to the cloud often involves more than a simple “lift and shift.” NServiceBus proves to be just as valuable in a cloud environment, but various aspects of its configuration and integration into the system need to be modified in order to take full advantage.

    One of our recent clients—a government agency—was already using NServiceBus and wanted to migrate their system to Azure. The steps we took to get NServiceBus ready to run in Azure may be helpful to you as you map your own cloud moves. I’ll walk you through exactly what we had to do differently in the cloud, explain the hybrid-cloud solution we built with NServiceBus for reporting, and demonstrate how we handled logging in the cloud, as well as our client’s need to run locally on occasion.

  • Has Microsoft really changed?

    Written by David Boike on April 25, 2019
    New Leaf
    Did Microsoft really turn over a new leaf?

    People have a lot of opinions about the “new” Microsoft under CEO Satya Nadella. They’ve embraced open-source, including .NET Core. They declared Microsoft ❤ Linux. They acquired GitHub. It’s been a wild ride for those of us used to the closed, dare I say grumpy Microsoft of the past.

    But are things different today? When the rubber hits the road, is Microsoft really more open, more accessible, more helpful?

    When we were building the Azure Service Bus transport for .NET Core we got a chance to find out.

  • NSBCon 2015: All about Transports

    Written by Particular Team on March 2, 2016

    Knowing which NServiceBus transport is best for your application is not easy. There are many factors involved in selecting a message transport; distributed transactions, legacy integration, cross-platform capabilities, and cloud deployments are a few that might be considered. At NSBCon 2015 Andreas Öhlund outlines the different transports that are available for NServiceBus. He covers the highlights and lowlights of each. Rather than telling you which transport is the right one, Andreas provides you with the tools to make that decision yourself, within the context of your project.
