Edge Functions vs Serverless for Solo Projects A Practical Comparison
📰 Dev.to AI
Learn when to use edge functions vs serverless for solo projects and how to combine them for optimal performance
Action Steps
- Run edge functions for tasks requiring sub-20ms cold starts, such as cookie gating and redirects
- Use serverless for tasks involving database queries, heavy dependencies, or long-running jobs
- Configure a split setup with edge functions handling fast tasks at the front door and serverless handling heavy lifting
- Compare the costs of edge functions and serverless using a cost calculator or a billing statement, such as Vercel's billing
- Test and optimize the performance of both edge functions and serverless using monitoring tools and benchmarks
Who Needs to Know This
Developers and engineers working on solo projects can benefit from understanding the trade-offs between edge functions and serverless architecture to optimize their application's performance and cost
Key Insight
💡 Edge functions are ideal for fast, low-latency tasks, while serverless is better suited for tasks that require heavy computation or database queries
