Building an IoT Smart Bin with ESP32 and Azure
I recently purchased an ESP32S IoT microcontroller from Amazon to explore its capabilities and gain hands-on experience with microcontrollers and sensors. After spending a few days setting up basic samples—such as LED control, WiFi connectivity, and sending touch sensor data to the cloud using MicroPython—I decided to tackle a fun proof-of-concept (POC) project: building a Smart Bin.
Run Azure Functions in a Docker Container
As you might already aware that .NET Core is a cross-platform applications targeting Windows, Linux and macOS and Docker gives more flexibility to run .Net Core application anywhere any devices. Latest Azure function version 2 runs on .NET Core, which means it is cross-platform. Anyone wants to run Azure function on Linux or small non-windows devices can easily run same Azure functions.
Maintain state in Azure Stream Analytics
Azure Stream Analytics is easy to get started. It only takes a few clicks to connect to multiple sources, sinks and to create an end-to-end pipeline, and is based on temporal window. Stream analytics maintain state based on window you are using in your ASA query. If you want to maintain some custom state based on your window result, I don't see any out of box solution.
Optimize the cost of Azure Cosmos DB
I used Azure Cosmos DB in many projects and heard common concern from application owner and stakeholder is Cosmos DB is best NOSQL database but it's very costly!
How to use Azure Key Vault Secrets using Manage Identity
One of the common concern of every application, either On-premises or Cloud, how to manage application keys and secrets? Keeping credential, secrets and other keys is an important task. Keeping sensitive information in code is not a good practice. Most people keep application keys and secrets in application config file (JSON or XML) and change those value according to environments. I followed the same practice with Azure Function, WebJob and Web App.
What is the reason of your Azure WebJobs stop/restart?
In this post, I shared how to use Azure activity log to find Azure WebJobs stop/restart problem.
