aws, iot, security, serverless


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.

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.

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 vs streaming data in AWS

aws, event-driven, streaming data


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.

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.
