In a previous post, I shared a bash script that enables you to effortlessly create an Amazon Machine Image (AMI) from an EC2 instance in AWS. The bash script introduced in today's post allows you deregister an AMI and delete all associated snapshots in AWS.

Microsoft will retire the Role-Based Access Control (RBAC) application impersonation role in Exchange Online in May 2024. Applications widely use this role in Exchange Online as it enables them to impersonate users in the tenant to perform actions on behalf of the users. You must migrate all your applications from using this role to other options. This article will explore Microsoft's reasoning behind this move and the current alternatives.

Azure App Service Automatic Scaling is a new feature that intelligently manages the number of instances of a web application. It analyzes real-time HTTP traffic and scales out (adds instances) or scales in (removes instances) to match demand. The most significant advantage of Automatic Scaling is that it simplifies web application management, offering a less complex approach than services like Azure Virtual Machine Scale Sets (VMSS) or Azure Kubernetes Service (AKS), which often require detailed rule definitions.

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.

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.

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.

This guide will explore adding an Azure Active Directory (Azure AD) group to the local administrator's group. This will enable Azure AD group members to perform tasks requiring administrator privileges on Windows 10 and Windows 11 computers.

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.

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.

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.

In my previous post, I shared a Bash and PowerShell script that enables you to swiftly generate an Amazon Machine Image (AMI) from an EC2 instance. In this post, I will be explaining how you can promptly launch an EC2 instance using the AMI.

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.
