Enable SSH for containerized Azure Functions
Very often, in the active development phase, regular logging does not help too much. Azure Functions that process some data or heavier payloads (like images or video files even) tend to store temporary processing data inside the container. By default, there's no way you can get inside the container to take a look at what's going on at the file system level. For such purposes, Secure Shell (SSH)

Design your app for the cloud (best practices)
I had no opportunity to write in recent days. In this topic, I decided to share something unusual and highly theoretical. I want to talk about the best practices for adapting apps for the cloud (Microsoft Azure, particularly, but most of them are applicable to any cloud provider). I hope that the concepts outlined below will help you to understand the process better, and hence, apply it in

Fixing an issue with self-hosted agents in Azure Pipelines
If you decided to go with a self-hosted agent(s) as I described in one of my previous articles, you might run into specific runtime issues related to the absence of a framework or software installed on a target machine.

Despite many similar topics over the internet, people still can’t make heads and tails around this theme and the explanation below is

The theory of control
The idea to write this topic came to me after a production system failure we experienced recently. Failures are unavoidable. Nothing is worse than having your business application down without the proper way to mitigate the issue. That’s exactly how the catastrophe may develop, i.e. due to the somebody's negligence, lack of experience, bugs sneaked into the software, natural disaster, hacker

AZ-102 my way and the new role-based certifications explained
Oh boy, what a week! It's been a hasty preparation as this exam retires tomorrow. I had to put in extra effort to get this done, and I am absolutely happy about my achievement. The funny thing - I was taking part in beta testing of this and other transition exams, but never had time to take it for real... Until the note from MS landed in my mailbox, saying that AZ-102 is about to retire soon. So,
