Cloud Native and Multi-Cloud Architecture: A Complete Guide to Modern Infrastructure
The evolution of cloud computing has fundamentally transformed how we architect, deploy, and operate applications. Cloud-native architecture and multi-cloud strategies are no longer optional—they’re essential for organizations seeking agility, resilience, and competitive advantage in the digital economy. This comprehensive guide covers cloud-native principles, multi-cloud strategies, Kubernetes orchestration, and practical implementation patterns with real-world examples. Cloud […]
Read more →Architecture Decision Records (ADRs): Documenting the Why
Code comments explain *what*, but not *why* a particular architectural decision was made. **ADRs** are lightweight Markdown documents capturing context, options considered, and the decision chosen. ADR Template Key Takeaways Store ADRs in the repo (`docs/adr/`). ADRs are immutable. If a decision changes, write a new ADR superseding the old one.

Service Bus is Azure’s fully managed enterprise message broker. It supports Queues (point-to-point) and Topics/Subscriptions (pub/sub). Choosing the right pattern prevents architectural headaches. Queues vs Topics Dead-Letter Queue Messages that fail processing N times go to a special DLQ for inspection and replay. Key Takeaways Use **Sessions** for ordered processing (FIFO for a specific session […]
Read more →Event-Driven Architecture with Azure Event Grid
Azure Event Grid is the backbone of event-driven architectures on Azure. It’s a fully managed event routing service that uses a publish-subscribe model. Unlike messaging services (Service Bus, Event Hubs), Event Grid is optimized for reactive programming patterns where you want instant notifications of state changes. Event Grid Architecture Key Concepts Topics are endpoints where […]
Read more →Dapr: Distributed Application Runtime Introduction
Dapr (Distributed Application Runtime) simplifies cloud-native development by abstracting away the complexity of distributed systems. It provides “building blocks” like Service Invocation, State Management, and Pub/Sub via a sidecar architecture. This means your code (C#, Go, Node) talks to localhost via HTTP/gRPC, and Dapr handles the infrastructure. The Sidecar Pattern Building Block: Pub/Sub Publish a […]
