Combining password policies for Active Directory and Entra ID (Azure AD)

Active Directory and Entra ID (formerly known as Azure AD) have their own password policies to prevent users from using weak and insecure passwords. While these policies can be combined, the level of protection achieved through this approach is still limited.

OpenTofu example (Terraform fork): Create an EC2 instance in AWS

HashiCorp changed Terraform's license from open source to Business-Source License (BSL). Soon after, the open-source fork OpenTofu became available. OpenTofu is an infrastructure-as-code (IaC) tool that allows you to define and manage your infrastructure in configuration files. In this post, I demonstrate with a practical example how to create an EC2 instance in AWS with OpenTofu.

L'efficacité énergétique est-elle incompatible avec nos usages exponentiels du web ? Non, bien au contraire. Les datacenters au cœur du réseau ont tout intérêt à optimiser leur fonctionnement. À l’image du fournisseur de services cloud Infomaniak, qui tente de changer la donne. Leurs équipes mettent d’importants moyens dans des datacenters nouvelle génération. Numerama est allé visiter celui de la coopérative de la Bistoquette, à côté de Genève.

Assign an IPv6 address to an EC2 instance and configure components with a bash script

In my previous post, I explained how you can quickly allocate an Elastic IPv4 address and associate it with an EC2 instance. As Amazon has recently started charging for in-use IPv4 addresses, you might want to consider switching to IPv6. Using the AWS Management Console to assign an IPv6 to an EC2 instance is not really straightforward. Several AWS network components must be correctly configured to make IPv6 work. The bash script introduced here checks all components, adds any missing pieces, and then assigns the IP to an EC2 instance.

In previous articles, I explained how to create an AMI from an EC2 instance and then launch the instance with scripts. Next, you probably want to assign an Elastic IP (IPv4 address) to the instance. In this post, you will learn how to allocate, release, associate, and disassociate an Elastic IP with the AWS CLI and bash scripts.

An example of using PowerShell to manage system and user-assigned managed identities in Azure

Managed identities provide secure authentication for resources accessing other resources in Azure without requiring sensitive information such as secrets, credentials, and certificates to be handled. Microsoft Entra ID manages these identities, enabling applications to obtain tokens for authentication. In this post, I will provide an example that illustrates how to use system and user-assigned managed identities with PowerShell.

Connect an Azure Function or Web App to a Key Vault to retrieve secrets with PowerShell

Azure Functions often require access to sensitive information. It is a security risk to store credentials in code or configuration files. Thus, protecting sensitive information like connection strings, API keys, or passwords is crucial. This is where Azure Key Vault comes in, offering secure and centralized storage for all your secrets. In this article, I will explain how to retrieve secrets from the Key Vault within an Azure Function using PowerShell.

Pulumi is an infrastructure-as-code (IaC) solution similar to Terraform. One advantage of Pulumi is that it allows DevOps engineers to use familiar programming languages to define, deploy, and manage cloud infrastructure. This post demonstrates how to deploy an EC2 instance with Pulumi.

Azure REST API: Manage Azure resources with the PowerShell cmdlet Invoke-AzRestMethod

Sometimes, managing certain Azure resources using PowerShell can be challenging due to the absence of specific cmdlets for those operations or services. This is where the Invoke-AzRestMethod cmdlet comes into play, which allows PowerShell scripts to communicate with Azure services by sending HTTP requests to Azure's REST API. It acts as a bridge between PowerShell and Azure services that still need to be integrated with cmdlets.

Create an Amazon Machine Image (AMI) of an EC2 instance with a Bash and PowerShell script

The provided Bash and PowerShell script helps automate the creation of Amazon Machine Images (AMIs) from existing AWS Elastic Compute Cloud (EC2) instances. This is particularly useful for creating point-in-time backups or disaster recovery. I mostly use the script to quickly clone an EC2 instance for testing or troubleshooting.
