Takeaways

• 🚀 AWS Amplify is a 'glue service' that helps developers quickly build full-stack applications, from front end to back end.
• 🖥️ Amplify supports various technologies, including JavaScript, React, Angular for web apps, and React Native, Android, iOS for mobile apps.
• 🔧 Amplify primarily functions through a CLI tool, though there is an Admin UI for basic administration tasks.
• 💡 Amplify allows easy integration of services like storage, authentication, and monitoring without needing to know the specific AWS services behind them.
• 🛠️ Behind the scenes, Amplify leverages services like AWS Lambda (functions), DynamoDB (datastore), Cognito (authentication), S3 (storage), and API Gateway (APIs).
• 📝 Amplify simplifies infrastructure management by using AWS CloudFormation under the hood to manage and deploy resources.
• 👨‍💻 The CLI workflow is straightforward, guiding users through commands like 'amplify add api' to add features like APIs to projects.
• ⚡ Amplify is excellent for rapid prototyping and fast development cycles, making it easy to add and remove functionality quickly.
• ❌ One major con is that users don't deeply learn AWS services, which can become problematic when troubleshooting issues outside of Amplify.
• ⚠️ There's potential for surprise bills, as Amplify provisions AWS services (like Cognito) behind the scenes, which can incur costs.
