This post discusses building composable serverless architectures with Fauna, Netlify, and Big Nerd Ranch. It highlights the benefits of serverless solutions in reducing operational management and allowing engineering teams to focus on product development. The post emphasizes the need for consideration of performance impacts when making architectural decisions, including cold start times, long running processes, network overhead, and vendor lock-in. It also covers common application needs such as authentication, database storage, and deployment of static assets to a Content Delivery Network (CDN). The post introduces Fauna as an ACID-compliant Serverless Database that provides strong consistency and temporal queries, and discusses how it can be integrated with Netlify for seamless deployment. Additionally, the post touches on handling cron jobs and long-running processes, Continuous Integration, and shared modules to keep code DRY. It also highlights front-end considerations such as using Web Components and provides a starter repository as an example to get started with building composable serverless architectures.
