4 quick tips for Serverless developers

Are you a serverless developer? Don’t worry, it’s probably where you last had it.

Seriously though, sometimes being a serverless developer can be a busy occupation and you don’t have time for endless waffle. With that in mind, here are four super-quick good practices to consider when designing your serverless architecture:

1. Decompose your application into small, focused functions: Each function should have a single responsibility and be independently deployable. This modular approach allows for better scalability, maintainability, and cost optimization.
2. Leverage event-driven architectures: Serverless functions are well-suited for event-driven scenarios. Design your application to react to events, such as changes in a database, file uploads to storage, or incoming HTTP requests. This enables your functions to be triggered only when needed, reducing idle time and costs.
3. Use asynchronous processing: Many serverless platforms support asynchronous function invocations. Leverage this capability to decouple time-consuming tasks from the main request flow. This allows your application to respond quickly to user requests while offloading heavy processing to background functions.
4. Optimize function packaging: Package your functions with only the necessary dependencies and libraries. Avoid including large frameworks or unused code, as it increases the function's size and startup time. Use techniques like code splitting and lazy loading to further optimize your function packages.

By following these best practices and embracing the serverless mindset, you can unlock the full potential of serverless architecture. You'll be able to build scalable, cost-effective, and maintainable applications that can adapt to changing business requirements with ease.
