(Part 4) Testing the limits of Windows Azure Service Bus


In the last post related to this subject we discover how we can process millions of messages over a network using Windows Azure Service Bus Topic. For the problem that we want to resolve we find out that 4 worker roles of Medium size is the perfect configuration for our case.
In this post we will talk about costs. We will see what the costs to process 10.000.000 messages are. We assume that messages are send to Service Bus from our on-premise servers. If the messages are send from our the same data center, the cost related to bandwidth would be 0.
Sending messages to Service Bus

  • Sending messages: 10$
  • Bandwidth cost: 27.46$ 

Receive messages from Service Bus

  • Receiving messages: 10$
  • Bandwidth cost: 0$ (we are in the same data center)

Worker role costs:

  • 4 medium worker roles: 8.64$

Remarks: From our results, we need 8h and 40 minutes to process 10.000.000 messages from Service Bus. In this time we included the warm up of each instance – 20 minutes. We calculate the cost of running 4 instances for 9 hours.
Windows Azure Table Storage:

  • Storage: 5$ (cost per month)
  •         Transactions:  2$

Remarks: In the transaction cost is included the cost of reading other data from Table Storage. Otherwise the cost of transaction to Table Storage would be maximum 1$ - because of batch support this value can be smaller.
The final cost of processing 10.000.000 messages and store them to Table Storage for 1 month is:

  • 63.1$ (when messages are send from on-premise servers)
  • 35.64$ (when messages are send from the same data center)

In theory, using this configuration, the price of each message processing would be 0.0003564$. What do you think about this cost? I would say that this is a pretty good price.
If we would need to process 10.000.000 every day, during a month, our final cost would be:

  • 924.2$ (when messages are send from the same data center)

In this post we saw what the costs of processing 10.000.000 messages are. Even if the costs look pretty good, I still have one thing that I don’t like - the time processing of all messages is pretty high – over than 1 hour and a half. In the next post we will see what we can do decrease the time processing.

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(

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
