Serverless Functions Overview

In Next.js, serverless functions are managed through specific files such as pages or app. Understanding how these functions interact with your application is crucial for optimizing performance and costs.

Function Invocations

• Pricing Metrics: Epycbyte charges based on the number of function invocations and their duration. Each invocation counts towards your bill, regardless of success or failure.
• Optimizing Function Invocations:
  • Use caching strategies to reduce repeated calls.
  • Implement lazy loading for static assets to minimize client-side requests.

Function Duration

• Calculating GB-Hours: The cost is determined by the number of vCPUs (virtual CPUs) allocated and the time your function runs. For example, a function running for 1 second on 1 vCPU costs 0.01 GB-hour.
• Optimizing Function Duration:
  • Adjust the maximum execution time to prevent long-running processes.
  • Use more vCPUs if your function requires additional resources.

Throttles

• Throttles count the number of times a request could not be served due to concurrency limits. While not directly charged, excessive throttles can lead to 429 errors and impact user experience.

Plan Usage

Managing Function Invocations

• Monitor your dashboard for insights into function usage.
• Use Epycbyte's grouping feature to track performance by function or route.

Optimizing Function Invocations

• Implement rate limiting on the client side to reduce unnecessary calls.
• Use tools like Varnish or Cloudflare Worker for caching and optimization.

Conclusion

By understanding and optimizing your serverless functions, you can minimize costs and improve performance. Regularly review your metrics and adjust configurations as needed to ensure efficient resource usage.
