Automating Cross-Account / Cross-Region Backups with AWS Backup in AWS Organizations

In this blog post we’ll dive deep into AWS Backup. We cover how the service works, how to set it up and focus on how it interacts with different AWS resources. It’s crucial to understand which features are supported for different services such as EBS or S3 to understand how to protect your environment. Additionally we look into Cross-Region and Cross-Account backup and restore options in the context of an AWS Organization.

Introduction to SSO with the IAM Identity Center and Entra ID

IAM Identity Center, formerly AWS SSO, is often used as an access management solution in front of one or more AWS accounts. More often than not, its purpose is to grant access to AWS accounts within an AWS organization. Today we’ll shed some light on the basic concepts and explain how this solution can be integrated with Azure AD which has recently been renamed to Entra ID to provide Single-Sign-On to your AWS environment.

Using undocumented AWS APIs with Python

It’s probably not a surprise that (almost) everything Amazon Web Services offers is accessible through web services. AWS also provides a range of SDKs that make interfacing with and integrating them in your code base relatively painless. These SDKs are sometimes a bit limited, though. There are certain things that you can only do through the AWS console, meaning that there are still services under the surface, but they’re undocumented and not accessible through the official SDKs. That API call is what we refer to as an undocumented API. In this post, I’m going to show you how to discover these APIs and use them in your scripts.

RAG AI-LLM Databases on AWS: do not pay for oversized, go Serverless instead

The RAG - Retrieval Augmented Generation is an approach to reduce hallucination using LLMs (Large Language Models). With RAG you need a storage solution, which is a vector-store in most cases. When you have the task to build the infrastructure for such a use case, you have to decide which database to use. Sometimes, the best solution is not the biggest one. Then you should go serverless to a smaller solution, which fits the use-case better. In this post, I introduce some of the solutions and aid you in deciding which one to choose.
