Build a Serverless Blog App with AWS Lambda
Use AWS Lambda, S3, API Gateway, and DynamoDB to create a fully serverless blog app that’s scalable, cost-efficient, and easy to maintain.Serverless architecture eliminates the need to manage infrastructure. With AWS Lambda, you pay only for compute time, and your app scales automatically to meet user demand—ideal for content platforms like blogs.
The goal is to build a secure, fast, and scalable blog platform using AWS services where users can read, create, edit, and delete blog posts with markdown support and cloud storage integration.
Post Creation & Markdown Editor
Allow authenticated users to create posts using a markdown editor and preview formatting in real-time.
Serverless API for Blog Actions
Use AWS Lambda functions triggered via API Gateway to handle CRUD operations for posts.
Cloud-Based Storage
Store blog post content and images on AWS S3 with public access for viewers.
NoSQL Database for Metadata
Use DynamoDB to store post titles, authors, timestamps, tags, and status flags.
This serverless blog system is powered entirely by AWS cloud components. Static content is hosted via S3 or Amplify, APIs run on Lambda, and post metadata lives in DynamoDB. Authentication is managed via Cognito or a third-party provider.
- Frontend: React.js or Next.js hosted on S3 or AWS Amplify
- Backend: AWS Lambda + API Gateway to expose REST APIs
- Storage: S3 for blog images/content and DynamoDB for metadata
- Authentication: AWS Cognito for login/session handling
- Optional: CloudFront for CDN delivery, SES for email notifications
Frontend
Next.js or React.js with Tailwind CSS, deployed via S3 or AWS Amplify.
Backend Functions
AWS Lambda functions triggered through API Gateway endpoints for post operations.
Storage & DB
Amazon S3 for content and media; DynamoDB for storing post metadata and tags.
Authentication
AWS Cognito or Auth0 for user authentication and access management.
1. Set Up S3 and Amplify
Configure static hosting for the frontend and optionally link it to GitHub for CI/CD.
2. Write Lambda Functions
Create Lambda functions to handle create, read, update, and delete operations for blog posts.
3. Connect API Gateway
Expose the Lambda functions through RESTful routes using Amazon API Gateway.
4. Store Content in S3 and Metadata in DynamoDB
Upload images and markdown files to S3, while storing titles, timestamps, and tags in DynamoDB.
5. Implement Authentication
Use AWS Cognito to restrict post creation and editing access to authorized users.
Blog Smarter with Serverless Infrastructure
Build a modern blog that scales automatically, eliminates server maintenance, and keeps costs low using AWS Lambda and cloud-native services.
