Spring Security Configuration with Flow Diagrams
In modern Java systems, Spring Security is widely used, offering numerous settings for various scenarios. This diversity can be confusing when more specific configurations beyond the default formLogin(withDefaults()) are needed. This article demonstrates basic configurations with detailed component analysis through diagrams and code examples, providing a starting point for further customization.

Being Functionless: How to Develop a Serverless Mindset to Write Less Code!
Dynamic cloud services like AWS Lambda have revolutionized computing, leading to rapid deployment and innovation in serverless technology. However, over-reliance on Functions as a Service (FaaS) can create complex architectures and increase costs. Adopting a functionless mindset and leveraging native service integrations fosters simplicity, enhances sustainability, and optimizes efficiency.

Beat the Plan: Probabilistic Strategies for Successful Software Delivery at Scale
Large-scale software delivery demands managing complexity across teams and organizations. Similarly to betting strategies in Vegas, embracing probabilistic thinking helps tackle uncertainty, shifting from rigid plans to adaptive systems. By making informed bets and designing for change, leaders can control volatility, respond to evolving conditions, and drive success in dynamic environments.

Architectural Intelligence – the Next AI
Architectural Intelligence is the ability to look beyond AI hype and identify real AI components. Determining how, where, and when to use AI elements comes down to traditional trade-off analysis. Like any technology, AI can be used creatively, but inappropriately. Identify if AI makes sense for your use case, then work to use it effectively to meet your needs.

Cell-Based Architecture Adoption Guidelines
The challenges in building modern, reliable, and understandable distributed systems continue to grow, and cell-based architecture is a valuable way to accept, isolate, and stay reliable in the face of failures. Organizations must ensure that the cell-based architecture is the right fit for them and that the migration will not cause more problems than it solves.

Securing Cell-Based Architecture in Modern Applications
Securing cell-based architecture is essential to fully capitalize on its benefits while minimizing risks. To achieve this, comprehensive security measures must be put in place. Organizations can start by isolating and containing cells using sandbox environments and strict access control mechanisms like role-based and attribute-based access control.

Taking Advantage of Cell-Based Architectures to Build Resilient and Fault-Tolerant Systems
Cell-based architectures offer a robust approach to building resilient systems. They achieve this through the core principles of isolation, autonomy, and replication. Each cell manages its resources and makes decisions autonomously. Observability for cell-based architecture requires a tailored approach to address the unique challenges and opportunities presented by this distributed system design.
