.NET 5.0 is out!

… or, globally available (GA), as Microsoft tends to say.
Technically, this is absolutely great news, because the newest version of the Microsoft development runtime brings a lot of new features, fixes and performance improvements.
It also cleans out a lot of the past architectural wanderings, the .NET platform has undergone in the recent years.
A really good summary of the new features and changes can be found in the .NET Core documentation.

V5 – A new engine for .NET!


Nevertheless, I always stand in wonder, how the marketing guys find the most confusing names for new products. Must be a contest.
With .NET 5.0, this is hilarious!
It is not .NET (well classic!), but based on Core, while the ASP .NET and Entity Framework parts keep “Core” in their names and, by the way, it does not replace .NET Standard.
I give 10 out of 10 obfuscation points…..

But nevertheless, developers, this is a great runtime and SDK release, so lets get over the naming accidents.
As always! 😉

Rent a gateway! – Azure Stack Edge

Some of us know the problem:

Bandwidth terror through an abundance of chatty sensors!

For example, in a manufacturing building, network traffic would go through the roof, if “everything” would be directly connected to the Internet (although, it is the Internet of Things) and, of course, it would be a security nightmare, too.
Well, let us leave the latter topic aside for a moment and stick to the traffic requirements.
The Cloud promise was, connect everything to the Internet and in the Cloud, magically, everything gets done!
While this is not false in a lot of scenarios, it is not always true!
Depending on solution use cases in focus, there are quite a few scenarios where distributed smart architectures have significant benefits over a centralistic approach.
In these cases devices on the “Edge” come into play. They are gateway devices running pre-processing logic and providing storage capabilities to handle part of the overall system workload on-premise, on the edge to the Internet. By doing this, enable the transformation of raw events into higher quality events, such as e.g. the reporting of temperature sensors only, if set limits are exceeded. The higher quality events are passed into the Cloud solution and are handled there to trigger related business logic.
Benefits of this design include

  • Significant lower traffic on central system
  • Better manageability / monitoring and security of data flow
  • Robustness against network outages (at least in some of the scenarios)

but, it comes with challenges, as well, such as:

  • Handling of business logic on the edge
  • Device management of IOT devices as well as edge devices

This needs to be taken into consideration!

However, if you are a vendor creating Cloud solutions experiencing a lot of data ingress, sooner or later you end up installing Edge devices to sort out raw events spamming your backend. You will buy devices and or talk to the customer to install these devices in the on-premise data-center.
The drawback with this approach is that it adds a lot of upfront cost to your solution.
Edge devices might be quite capable, full-fledged and therefore expensive servers that a customer may also want to include into his system management to keep them patched and secure. This triggers often time consuming approval processes to get things into place.
All of this may kill your project or POC before it even has started!

So, is there a smarter way to approach this issue?
As you may have guessed from the title of the post, there is. Microsoft is extending its Cloud-native rent-my-system approach to edge hardware and software. In this case the system of interest is called Azure Stack Edge (fka Azure Data Box Edge – Microsoft likes the renaming game, as we know).
There is a very informative IOT Show episode on this solution, still using the old name.

Benefits of the Cloud-rental approach are that the Stack Edge devices are managed centrally via an Azure service. The service allows the installation and management of Azure IOT edge modules taken over the responsibility for the distributed logic in the system. Looking at IOT devices, it is especially interesting that these devices can be connected to a local (Edge) instance of IOTHub and also be managed from there, which gives you the best of both worlds: The devices are safe behind the firewall, but still accessible via the Edge gateway for administrative purposes!
Microsoft operates the Edge devices as an appliance, which means it takes over responsibility for any OS (Stack Edge is running on Linux) or runtime patches.
IOT Edge modules deployed can be available building blocks from Microsoft or 3rd party vendors, as well be self-developed Edge modules suiting the implemented solution.

This is really powerful, because it leaves solution developers the flexibility to draw existing commercial building blocks e.g. for AI or highspeed processing from Azure Marketplace and focus on the business needs of the solution.

If a customer needs a test at their location, the rental model is not to beat. Just ship your devices and a pre-configured Edge device and a POC can be up and running in minutes, not costing a fortune and hardware. If not suiting, it can be stopped any time with out wasting more costs and energy.

Looks like a quite innovative, efficient and modern approach to me! 🙂

Microsoft Build 2020 coming up this week!

Microsoft teams have geared up, this time, of course, virtually, to present all the newest stuff from their development repositories. Looking at Azure IOT there is quite some interesting information in the pipe.
Focus, this year, seems to be on Azure Sphere and Digital Twins, although they might come up with some new stuff, as well.

So tune in, I’ll be there. 🙂

Interesting Industrial Azure IOT showcases from Festo, Kao, and AkzoNobel

We just stumbled about some quite interesting new showcases in the Industrial Azure IOT space that demonstrate quite good the bandwidth of different services leveraged in Azure ranging from operating IOT devices in the field to using AI and Machine learning creating new and innovative products by turning Big Data into Smart Data.

Festo for example, uses Azure IOT to create dashboards providing insight on all their deployed industrial IOT devices.

Azure networking capabilities move into the edge!

When implementing telemetry solutions with mobile systems, network latency can be a quite limiting factor. Communication retries are costly and also hinder a system to provide a real-time view on the current state.
To mitigate this risk you now are able to leverage Azure Edge Zones! Microsoft is teaming up with some Telcos leveraging the new 5G to provide a fast lane into Azure data centers.

Azure Edge Zones – 5G access directly into Azure

This is approach, combining all the newest technologies, is able to provide ultra-low latency in the area of milliseconds response times. Especially looking at older mobile connections this is a performance gain in more than an order of magnitude and a great enabler, if your solution requires to be as close to reality as possible.
It is certainly also interesting to mention that this technology is also available for on-premise solutions, keeping the same APIs and services. Due this your solution can be ready for any network scenario.
