Azure Service Bus Premium - Better latency and throughput with predictability

A few days ago the public preview of Azure Service Bus Premium was announced. The first two things that people usually check at a new service like this is price and the added value. In this post we will talk about them.

Added Value
The biggest things between the standard offer and Premium is the dedicated VMs that are reserved only for the end customer. Each VM that is used by Azure Service Bus Premium is isolated from the rest of the customers and will be used only by him.
This means that the performance of the Azure Service Bus will be predictable. This is a very important quality attribute, especially when you need to know exactly how long it takes for a message to arrive at final destination, when latency and throughput needs to be predicted.
When you decide to use the Premium offer, the storage engine that will used behind the scene will not be the standard one, used by Service Bus, but the new one, used by Azure Event Hub - so called Jet Stream.
In this way, we can have dedicated resources (Message Unit) for our namespaces.

Capacity
The capacity of this system is called Message Unit (MU). This capacity unit is dedicated for each namespace that you creates. This means that you can have multiple Service Bus Topics under the same Message Unit. When you need better performance, you can create dedicated Premium namespaces, for each resource (Topic).
The Message Units for each namespace can vary from 1 to 4. Each MU will offer us an isolated "VM", with dedicated resources.

Price
In this moment, in preview mode, the price of Azure Service Bus Premium is 9.368€ per day for each Message Unit (current price is valid only for preview).

Let's see what we can with it (smile).

Windows Docker Containers can make WIN32 API calls, use COM and ASP.NET WebForms

After the last post , I received two interesting questions related to Docker and Windows. People were interested if we do Win32 API calls from a Docker container and if there is support for COM. WIN32 Support To test calls to WIN32 API, let’s try to populate SYSTEM_INFO class. [StructLayout(LayoutKind.Sequential)] public struct SYSTEM_INFO { public uint dwOemId; public uint dwPageSize; public uint lpMinimumApplicationAddress; public uint lpMaximumApplicationAddress; public uint dwActiveProcessorMask; public uint dwNumberOfProcessors; public uint dwProcessorType; public uint dwAllocationGranularity; public uint dwProcessorLevel; public uint dwProcessorRevision; } ... [DllImport("kernel32")] static extern void GetSystemInfo(ref SYSTEM_INFO pSI); ... SYSTEM_INFO pSI = new SYSTEM_INFO(

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine: threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded.

On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration: TeamCity .NET 4.51 EF 6.0.2 VS2013 It see

Navigating Cloud Strategy after Azure Central US Region Outage

Looking back, July 19, 2024, was challenging for customers using Microsoft Azure or Windows machines. Two major outages affected customers using CrowdStrike Falcon or Microsoft Azure computation resources in the Central US. These two outages affected many people and put many businesses on pause for a few hours or even days. The overlap of these two issues was a nightmare for travellers. In addition to blue screens in the airport terminals, they could not get additional information from the airport website, airline personnel, or the support line because they were affected by the outage in the Central US region or the CrowdStrike outage. But what happened in reality? A faulty CrowdStrike update affected Windows computers globally, from airports and healthcare to small businesses, affecting over 8.5m computers. Even if the Falson Sensor software defect was identified and a fix deployed shortly after, the recovery took longer. In parallel with CrowdStrike, Microsoft provided a too
