Azure Cosmos DB is powerful but can be expensive if misconfigured. The “Request Unit” (RU) model abstracts hardware, but understanding it is key to cost control. This guide covers partition key selection, indexing policies, and the new Autoscale throughput. Understanding Request Units (RU) 1 RU = 1 Read of a 1KB document by ID. Queries […]

React Class to Hooks Migration Guide
React Hooks (introduced in 16.8) are now the standard. Class components with `this.setState` and lifecycle methods are legacy. This guide provides direct translation patterns for migrating typical class components to functional components with Hooks. State Management: useState Lifecycle: useEffect `useEffect` replaces `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`. Common Pitfall: Stale Closures Hooks capture the state *at the […]

Even with tools like CDK, understanding the underlying CloudFormation mechanics is crucial. Improperly structured stacks can lead to circular dependencies, update rollbacks, and stuck resources. This guide covers nested stacks, cross-stack references, and drift detection. Cross-Stack References vs Nested Stacks Feature Cross-Stack Refs (Export/Import) Nested Stacks Coupling Loose (Independent lifecycles) Tight (Parent controls Child) Updates […]

CloudFormation YAML is verbose and lacks logic. The AWS Cloud Development Kit (CDK) allows you to define cloud resources using imperative languages. In this guide, we build a complete serverless stack (Lambda + API Gateway + DynamoDB) using TypeScript. The Construct Tree CDK components are called “Constructs”. Level 1 (L1) constructs are 1:1 mappings to […]
