CrateDB is a distributed SQL database built on a NoSQL foundation. It is familiar to use, simple to scale, and versatile for handling any type of structured or unstructured data with real-time query performance.
It’s always nice being able to choose from several services like databases. So I checked out how to develop a simple application and Azure IoT Edge module against Crate if running in a container.
In this blog, we see how we can use the CrateDB in Azure IoT Edge.
Since 2016, I have been involved in the world of LoraWan.
The combination of low powered devices together with long-range communication makes this protocol ideal for sending short messages from remote locations. It even supports two-way communication.
One of the most famous players in this knowledge area is The Things Network. They provide a set of open tools and a global, open network to build your next IoT application at low cost, featuring maximum security and ready to scale with LoraWan.
Its community is thriving on both enthusiastic makers, starters, and companies which are building their IoT solution on that backend.
This is not just an update. This is a completely new stack, built from the ground up and the team invests into a clean, portable, open-sourced backend. This new stack is standards-compliant by default and it will support the Lora 1.1 specification too. The V3 backend is designed for scale, for ‘N’ as they say (N customers, N regions, N devices, N versions):
We see the devices and gateways on the left, the V3 stack in the middle, and the third-party cloud integrations (eg. AWS, Azure) on the right.
In this blog, we look at registering a gateway and a device in the new TTN V3 Stack portal. And we integrate cloud connectivity.
In the past, I wrote an article on how to get Azure service tags. Back then, I was not able to access the Rest API provided.
A service tag represents a group of IP address prefixes from a given Azure service.
This week I revisited the API and dived a little deeper into this call.
In this blog, I show you how to read service tags using the Azure Rest API and we learn how to cope with the bearer token if we want to access the Access API. I show it both in Postman and using C# code.
