| Track IP addresses consumption with Azure Application Insights |
| |
| |
This tutorial will show you how to track the number of IP addresses used on your Azure Virtual Network subnet by sending custom event telemetry to an Azure Application Insights instance.
You will learn how to use PowerShell to send this telemetry and how to use the information to set up Azure Monitor alerts for when a subnet is close to full.
It also covers how to graph IP address consumption using this data. |

| Use Managed HSM for encryption and decryption |
| |
| |
| This article explains how to use Managed HSM (Hardware Security Module) instead of Key Vault in order to encrypt and decrypt messages in Azure. Managed HSM allows for faster encryption and decryption using AES256, and also allows for EC and RSA encryption. The article goes over the steps needed to create and activate an Azure Managed HSM, as well as the prerequisites and RBAC configuration required to authenticate and access the HSM in Azure. |

| Hosting a Capture-the-Flag event on Azure |
| |
| |
In this article, the author discusses the use of Capture the Flag (CTF) events as a way to improve team morale and upskill on new technologies. CTFs are traditionally cybersecurity exercises, but they can also be used to teach and practice other engineering practices.
The author mentions OpenHack, which is similar to CTFs but includes topics such as AI, ML, DevOps, containers, and security. The author also introduces CTFd, an open-source CTF framework, and explains how to set up a self-hosted CTFd environment using Azure PaaS.
The article includes a diagram of the infrastructure setup, which includes a Virtual Network, CTFd App Service, Azure Database for MariaDB, Azure Cache for Redis, and Azure Key Vault. The article includes links to the GitHub repository for the code and deployment scripts. |

| ChatGPT to author Bicep templates? |
| |
| |
This article talks about using ChatGPT, a large language model developed by OpenAI, to write infrastructure as code using Bicep. It shows an example of using ChatGPT to generate a Bicep template for creating a Vnet and how it can also generate a parameter file.
The author notes that while ChatGPT can assist with writing code, it should not be used to replace human programmers and should be used with caution in production environments.
The author also mentions that ChatGPT is trained on data current as of 2021 and may not have information that is more recent. |
