Reaching a global audience often means providing content in multiple languages. In this post, I explore how I extended my event-driven blog pipeline with automated translation capabilities using Amazon Nova Pro, enabling my technical content to reach readers in German, Spanish, French, Italian, and Portuguese.

Writing technical content as a non-native English speaker often means spending significant time proofreading for spelling and grammatical errors. In this post, I explore how I extended my existing event-driven blog CI/CD pipeline with automated proofreading using Amazon Nova and Amazon Bedrock, seamlessly integrating AI-powered text correction.

Taking our authorization system to the next level! In this third part of our series, we're enhancing our Amazon Verified Permissions (AVP) solution with Attribute-Based Access Control (ABAC). By combining RBAC and ABAC, we get a powerful authorization system that can enforce fine-grained access based on user attributes and context - perfect for multi-tenant applications where access control needs to account for more than just roles.

As authorization needs evolve, managing access efficiently becomes even more crucial. In this follow-up post, we extend our Policy Decision Point (PDP) and Policy Enforcement Point (PEP) solution by introducing Amazon Verified Permissions (AVP) for fine-grained authorization. Instead of storing permissions in DynamoDB, we leverage AVP’s centralized policy engine and Cedar policy language to define and enforce access control dynamically.

Authorization is a critical part of securing cloud applications, and understanding the best practices for implementing it can make all the difference. In this post, we dig deep on the concepts of Policy Decision Points (PDPs) and Policy Enforcement Points (PEPs), and how they work together to manage user access efficiently. We dive into a serverless solution using AWS Lambda and API Gateway, implementing Role-Based Access Control (RBAC) for fine-grained access control based on Cognito User Groups. This solution ensures scalability, low latency, and efficient authorization in serverless environments.

Secure communication is a important in IoT systems, where certificates and trust play a vital role. In this post we extend the API introduced in part 1, we will add functionality to create device certificates, introduce an inventory, add some event-driven parts, and the possibility to list and get certificates. This hands-on approach is great for learning purposes and development environments, production setups however require robust managed solutions.

Secure communication is a important in IoT systems, where certificates and trust play a vital role. In this post, I explore the foundations of certificate management, including PKI, certificate chains, and trust. Also I introduce a serverless self-service API using Amazon API Gateway and Lambda for an easy way to create certificates. This hands-on approach is great for learning purposes and development environments, production setups however require robust managed solutions.

In this post, I extend the File Manager service I built previously by adding content moderation capabilities. The original service stores files in S3 and records them in a DynamoDB table, using a serverless, event-driven approach. Now, with AWS GuardDuty and Rekognition, I’ve enhanced the service with malware scanning and image moderation.

re:Invent is one of, if not the biggest, tech conferences in the world. Attending re:Invent for the first time can be overwhelming. In this post I try give you some advice how to survive not only re:Invent but also Las Vegas as a first time attendee.

In part four of the series about the world of BBQ, where tradition and technology rarely cross paths. The future of grilling is here, and it’s connected, smart, and runs on the cloud! We look at the key difference between Authentication and Authorization in a SaaS solution. We introduce a new authorization architecture with a centralized Policy Decision Point (PDP) and distributed Policy Enforcement Points (PEPs) implemented serverless with API Gateway and Lambda.

In part three of the series about the world of BBQ, where tradition and technology rarely cross paths. The future of grilling is here, and it’s connected, smart, and runs on the cloud! I continue with tenant management using an serverless and event-driven approach with EventBridge, StepFunctions, API Gateway, Lambda, and Cognito User Pools.

One of the major reason that I write all of these blog posts is to help people learn about cloud and AWS. How would you know that you understood what you read and learned from it? In this post I discuss how I introduced gamified learning by adding a quiz from kvist.ai on my blog posts, directly from my CI/CD pipeline running as an event-driven system using Amazon EventBridge and AWS StepFunctions.

Events are changes in a system’s state, often triggering specific actions, while data streams represent continuous flows of data elements over time. Events can form part of data streams, but not all data streams are composed of events, as they may include continuous data points like sensor readings. AWS offers services like Amazon EventBridge and SNS for managing events, Amazon Kinesis for, real-time data streams, and IoT Core that can handle both, making it possible to handle both concepts in cloud.

In part two of the series about the world of BBQ, where tradition and technology rarely cross paths. The future of grilling is here, and it’s connected, smart, and runs on the cloud! I continue with user management using an serverless and event-driven approach with Cognito User Pool together with Lambda, EventBridge, and StepFunctions.

In the world of BBQ, tradition and technology rarely cross paths. But what if I told you that the future of grilling is here, and it’s connected, smart, and runs on the cloud? In this blog series, I will explore how AWS IoT, serverless, and event-driven architecture enables an automated cooking experience. As a tech-savvy griller, I discover how cloud technology can elevate my grilling game to a whole new level.

Serverless and event-driven workloads on AWS are well known for their inherent high availability and scalability, offering a robust platform right out of the box. In the world of cloud, it's well known that everything fails all the time. This reality becomes even more complex when serverless systems interact with non-serverless components. In this post, I'll dig into architecture concepts that can help you handle failures effectively.

In this post we'll look at Amazon Verified Permissions (AVP) a serverless service for easy management and enforcement of application permissions, and how to use it to secure Amazon API gateway API together with Cognito User Pools.

AWS offers several great serverless services for data engineering and analytics. In this post I describe my serverless analytics setup for click stream analytics of a static webpage, using Amazon Glue, Athena, Managed Grafana for analytics. Data ingestion and storage with Lamba@Edge, StepFunctions and S3.

Introducing My Serverless Handbook. This will be the home to my serverless experience and learnings on AWS. It all started 2015 with the creation of my first Lambda function, now several years later, serverless solutions are still my passion. This is my story, this is my journey, this is my experience!

Calling an API from AWS StepFunctions has for a long time required us to write a Lambda function to handle that. With the release of HTTP EndPoint there is no need for that anymore. In this post I'll go over the functionality and show how to use it.

How do we efficiently redirect users from one site to an other? In this post we'll create a solution using serverless technologies to handle this redirect in an efficient way. We'll use AWS, CloudFront, and the new Function KeyValueStore.
