Distributed Transactions: An Intuitive Deep Dive
Distributed transactions: A deep dive into cross-service atomicity, database consistency, and failure recovery. Explore 2PC, Sagas, and more to ensure data integrity across microservices.
How To Handle Distributed Transactions in Microservices
Distributed transactions are the hardest part of microservices. This guide breaks down proven patterns—sagas, outbox, idempotency—with real code and lessons from production. Learn which frameworks to use, how to survive failures, and how to build systems that stay consistent without sacrificing scalability. Perfect for engineers and teams designing modern microservice architectures.
Designing a High-Performance Static+Dynamic Web Architecture with CDN and Next.js
Building a scalable web app is more than picking a framework—it’s about orchestrating edge caching, rendering modes, and automated pipelines for peak performance. This post breaks down real-world architecture patterns with CDN and Next.js, benchmarks static vs. dynamic rendering, and highlights CloudFront best practices. If you’re architecting for millions of users—or want a blueprint for hybrid static/dynamic scale—start here.
Evolving Scalability and Maintainability from 10K to 1M+ Daily Active Users
Discover concrete system architecture patterns and engineering trade-offs for scaling platforms from 10,000 to over 1 million daily active users. A senior engineer’s guide to maintainable code, microservices, distributed databases, multi-region deployments, caching, CI/CD, and service mesh—no buzzwords, just actionable advice.
Resolving RAC0690 on Dell PowerEdge Servers Running Ubuntu 20.04
Learn how to resolve the RAC0690 warning on Dell PowerEdge servers running Ubuntu 20.04 by installing the iDRAC Service Module (iSM). This step-by-step guide covers the cause of the warning, why iSM is essential for full hardware observability, and how to enable seamless integration between your OS and Dell’s iDRAC management interface.
Hard Lessons from Operating Stateful Systems on Kubernetes: Why We Moved Away from EFS
Learn why Amazon EFS fell short for stateful workloads on Kubernetes and how moving to image-based deployments with node-local persistent volumes improved speed, reliability, and operational control. This post shares real-world performance data, practical architecture tips, and key lessons for running production-grade systems.
