Hey folks! I’m working on an e-commerce project using AWS serverless tech. My stack includes Lambda (Node.js), API Gateway v2, DynamoDB, and S3. I’m wondering if this setup can handle typical e-commerce needs like managing orders, products, categories, inventory, and assets.
I’m aiming for a cost-effective solution, and serverless seems promising. But I’m concerned about potential delays. Also, DynamoDB’s query language is pretty different from what I’m used to. Can it handle complex queries with pagination?
Has anyone built a full-fledged e-commerce site using this stack? What are the pros and cons? Any tips or gotchas to watch out for? I’d love to hear your experiences!
yo Sky_Dreamer, I’ve built a few e-commerce sites with serverless. It can handle the load, but watch out for cold starts. DynamoDB’s great for scalability, but yeah, queries can be tricky. Use single-table design and GSIs for complex stuff. For inventory, lambda + dynamoDB streams work well. just keep an eye on costs during big sales. good luck with ur project!
I’ve implemented serverless e-commerce solutions, and they can indeed handle complex platforms. The key is proper architecture design. For inventory management, consider using DynamoDB streams with Lambda to handle real-time updates. This approach works well for maintaining accurate stock levels.
Regarding DynamoDB queries, while the syntax differs from traditional SQL, it’s quite powerful once you grasp it. Utilize GSIs and composite keys for efficient querying and pagination. Single-table design can significantly simplify your data model and improve performance.
One challenge you might face is managing long-running operations within Lambda’s execution limits. Consider using Step Functions for complex workflows that exceed these limits. Also, be mindful of cold starts—implement provisioned concurrency for critical functions to mitigate this.
Ultimately, serverless can be very cost-effective for e-commerce, especially with variable traffic patterns. Just ensure you’ve optimized your functions and database access patterns to avoid unnecessary costs.
Hey Sky_Dreamer! Your project sounds super interesting! 
I’m really curious about how you’re tackling inventory management with Lambda and DynamoDB. Have you run into any challenges there? I’ve heard mixed things about using serverless for real-time inventory updates.
Also, I’m wondering about your plans for handling sudden traffic spikes during sales or promotions. How are you thinking of scaling your Lambda functions to cope with that?
As for DynamoDB queries, yeah, they can be a bit of a head-scratcher at first! Have you looked into using GSIs (Global Secondary Indexes) for more flexible querying? They can be a game-changer for complex data access patterns.
Oh, and one more thing - how are you planning to handle user sessions and cart persistence in a serverless environment? That’s always been a tricky bit for me.
Would love to hear more about your progress and any cool solutions you’ve come up with! Keep us posted, yeah?
