Architecture Patterns — Cloud Computing

Match architecture weight to each runtime's init-amortization: lean handlers on single-purpose Lambda, more on a Lambdalith, full OOP/DI only on long-lived runtimes.

How to slice AWS Lambda functions: default to single-purpose, treat the single-domain Lambdalith as an earned exception, and the platform forces that decide it.

Production deploys need a real approval gate: use GitHub Environments with native protection rules and scoped secrets, not workflow if: hacks or marketplace actions.

Building a RAG agent on AWS Bedrock + Knowledge Bases + OpenSearch Serverless with CDK in TypeScript: architecture, IAM wiring, automated ingestion, and the chat UI.

What a Bedrock Knowledge Base really is, which data sources and vector stores are first-class, and why the console default rarely fits a small corpus.

Named signals that justify a Kafka migration from a managed event bus, and a four-phase outbox-anchored playbook to move without rip-and-replace.

DI containers, monolithic SDKs, god-handlers, top-level secret fetches, and heavy ORMs - what they cost on cold start, and the functional shape that replaces them.

An exploration of whether a Rust + WASM image-resize handler fits inside Cloudflare Workers' binary-size, memory, and CPU ceilings before the POC runs.

A platform-engineering default for multi-team AWS orgs: one event, many consumers, each in its own account with its own SQS and DLQ, fan-out lives in the event bus layer.

An exploration thesis: vendor lock-in in event-driven systems lives in the bus topology, not the runtime, and wasmCloud plus NATS make the bus portable.

Enterprise patterns for Model Context Protocol: tool composition, multi-agent orchestration, role-based access control, and production observability.

A practical 6-level framework for enterprise AI integration: when to use ChatGPT, RAG, MCP agents, or fine-tuning, with a focus on PII and finance compliance.

A practical guide to multi-tier caching: in-memory, Redis, and CDN layers, cache-aside vs write-through, ElastiCache vs MemoryDB, and stampede prevention.

Building scalable real-time APIs with AWS AppSync: JavaScript resolvers, subscription filtering, caching strategies, and infrastructure as code patterns.

Implement secure cross-account event distribution with Amazon SNS and SQS: IAM policies, KMS encryption, AWS CDK, and common production pitfalls.

A technical comparison of MQTT, AMQP, ZeroMQ, CoAP, and DDS for IoT logistics: fleet tracking, cold chain monitoring, and real-time device communication.

A beginner's guide to OpenTelemetry covering traces, metrics, and logs with practical implementation examples, common pitfalls, and a terminology glossary.

A practical guide to implementing customer relationship management using event sourcing, CQRS, and event-driven patterns for marketing automation and consent management

A practical introduction to Traefik for developers familiar with nginx. Learn core concepts, setup examples, and when to choose Traefik over traditional reverse proxies.

Learn to build automated preview environments using AWS CDK, Lambda, and GitHub Actions for seamless PR testing and review workflows

A technical case study on implementing multi-version APIs in production. Failed approaches, working solutions, and CDK patterns for managing API evolution.

Handle large file uploads with S3 signed URLs instead of Lambda proxies, including a full CDK implementation, security considerations, and lessons learned.

Production-ready DLQ patterns for event-driven systems: monitoring, circuit breakers, exponential backoff, recovery, and the anti-patterns worth avoiding.

Removing factories, services, and dependency injection from our Node.js microservices cut 40% of the code and most of the bugs, here is why functions won.

A practical guide to evolving Node.js monoliths into event-driven serverless functions, with migration strategies and proven architectural patterns.

Multi-account AWS architecture patterns for resilient event-driven systems: account structure, EventBridge routing, and cross-service communication.
