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.

Serverless EventDriven AWS Devops
This talk will explore how a fintech market leader in Sweden, created a serverless and event-driven integration with Slack on AWS. Creating a solution, to automate tasks across a multi-account setup. Learn how this journey optimized cost, enhanced productivity and security by eliminating repetitive tasks, by minimizing human error. A key aspect was integrating alarms and notifications directly into Slack, enabling developers to take immediate action on system alerts. We will look at the problems, deep dive into implementation, and the challenges we faced. Join us to gain valuable insights and practical tips for transforming your workflows.

Serverless IoT AWS
In large-scale IoT systems, where thousands of devices are constantly communicating, data and control messages can flow unpredictably and at varying rates throughout the day. Serverless and event-driven architectures provide a dynamic and efficient solution to this challenge. In this session, we’ll explore why serverless is a great fit for IoT, particularly in handling data ingestion and management. We’ll dive into the key architectural patterns used in IoT systems, highlighting how event-driven design enables scalability, flexibility, and cost optimization. I’ll also walk you through an architecture I designed for an IoT use case, showcasing the integration of various AWS services tailored for data ingestion, processing, and analytics. Along the way, we’ll discuss the challenges encountered and lessons learned during development, offering actionable insights into the unique aspects of building serverless IoT solutions. Join me to understand how serverless and event-driven architectures can unlock the full potential of IoT, enabling resilient and scalable systems that are easy to manage and adapt to evolving demands.

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.

Serverless AWS DevOps
In today’s fast-paced development environments, reducing manual tasks is crucial for productivity. This talk will explore how MyMoney, fintech market leader in Sweden, leveraged Slack integrated with AWS, creating an event-driven solution, to automate tasks across a multi-account setup. Learn how this journey enhanced productivity and security by eliminating repetitive tasks, minimizing human error. A key aspect was integrating alarms and notifications directly into Slack, enabling developers to take immediate action on system alerts. We will look at the problems, implementation, and challenges faced. Join us to gain valuable insights and practical tips for transforming your workflows. Audience will learn how we integrated our DevOps way of working and tooling with Slack to automate tasks, boosting productivity, creating better developer experience and at the same time reducing cost. Key Takeaways: - How to automate task to increase developer experience - How to create an event-driven solution across multiple AWS accounts - Using automated scheduling to save cost.

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.

Serverless resiliency AWS
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. However, in the world of cloud, it's a well known that everything fails all the time. This reality becomes even more complex when serverless systems interact with non-serverless components, which may not possess the same agility in scaling.

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.
