Introducing Local emulator for Azure Service Bus
Azure Service Bus is a fully managed enterprise message broker offering queues and publish-subscribe topics. It decouples applications and services, providing benefits like load-balancing across workers, safe data and control routing, and reliable transactional coordination. In response to your feedback, we are pleased to announce the introduction of a local emulator for Azure Service Bus. This emulator is intended to facilitate local development experience for Service Bus, allowing developers to develop and test their code against Azure Service Bus, in isolation away from cloud interference. Why emulator? Developers across the globe love emulators! While there are numerous compelling reasons to use emulators, here are just a few of those reasons to consider: Optimized development loop: The emulator speeds up dev/testing against Azure Service Bus. Pre-migration trial: Try Azure Service Bus using your existing AMQP applications before migrating to the cloud. Isolated environment: Use the emulator for dev/test setup without network latency or cloud resource constraints. Cost-efficient: The emulator is free and can be run on your local machine for dev/test scenarios. Note: The emulator is intended only for development and testing. It should not be used for production workloads. Official support is not provided, and any issues or suggestions should be reported via GitHub. Get started with Service Bus emulator The emulator is accessible as a Docker image on Microsoft Artifact Registry, and it is platform-independent, capable of running on Windows, macOS, and Linux. You can use our automated scripts from the Installer repository or initiate the emulator container using the docker compose command. The emulator is compatible with the latest service bus client SDKs and supports a wide variety of features within Azure Service Bus.

Please provide feedback or report any issues on our GitHub repository. Wishing you a smooth ride with the Service Bus emulator, making all your tests pass! 😊Azure Service Bus Premium: Large Message Support Generally Available
The "Large Message" feature of Azure Service Bus Premium is now generally available for production use. The feature is a new, per-entity message size limit configuration setting that can range from 1MByte to 100 MByte and defaults to 1 MByte. The generous 100 MByte limit enables a broad range of queue-based document transfer use-cases. The configurability of the limit ensures that your application is protected from messages that are larger than expected in existing buffers and by memory configurations and can be set to the exact limits you need.Upcoming changes to IP-addresses for Azure Service Bus
At Azure Service Bus we are upgrading our infrastructure to the newest technologies, allowing us to use the latest features available. Due to this infrastructure change, the IP-addresses associated with our customers’ namespaces are also going to change. Your Service Bus based solutions may break if you are not following the best practices of using service tags or domain names in your firewall or network devices configurations to allow communication with this service, but are instead using these IP-addresses.Announcing Service Bus Explorer for Azure portal public preview
Today we are pleased to announce the preview of the completely revamped Service Bus Explorer tool on the Azure portal. While we have offered a portal-based Service Bus Explorer for data operations for a while now, our customers have provided us with feedback that the experience was still lacking compared to the community managed Service Bus Explorer OSS tool. To empower our customers even further, we are now releasing a new version of Service Bus Explorer, which brings many new capabilities to the portal for working with their messages, right from the portal.
Steps to upgrade control plane API references for Azure Service Bus, Event Hubs and Relay
On 30 September 2026, Azure Resource Manager control plane APIs 2014-09-01, 2015-08-01, and 2016-07-01 will be retired. Migrate to the latest control plane API version by that date to avoid potential service outages in Azure Service Bus, Event Hubs, and Relay. The latest API for control plane operations, version 2021-11-01, offers feature updates and performance improvements to make your applications more resilient.
