In the ever-evolving world of web development, serverless architecture is a buzzword you canโt ignore.
But is it the magic bullet for every project?
Letโs break it down โ the good, the bad, and when you should (or shouldnโt) go serverless.
๐ What Is Serverless Architecture?
Serverless doesnโt mean no servers โ it means you donโt have to manage them. Cloud providers like AWS, Azure, and Google Cloud handle server management, so you can focus purely on code.
Popular services:
AWS Lambda
Google Cloud Functions
Microsoft Azure Functions
If you want a hands-on example, hereโs an AWS Lambda tutorial to get started.

Pros of Serverless Architecture
Cost-Effective: Pay only for what you use (goodbye, idle server costs).
Scalability: Auto-scales to handle any traffic surge without manual intervention.
Faster Deployment: Focus on writing features, not infrastructure.
Reduced DevOps Burden: No server maintenance, patching, or capacity planning.

Cons of Serverless Architecture
Cold Starts: Functions can take longer to spin up after being idle.
Limited Execution Time: Not great for long-running processes.
Vendor Lock-in: Switching providers can be painful.
Complex Debugging: Troubleshooting distributed functions isnโt always straightforward.
Hereโs a GitHub repo for an open-source serverless framework, if you want to experiment without full cloud lock-in.
When to Use Serverless Architecture?
Itโs a perfect fit for:
APIs & Microservices
Scheduled Tasks & Automation
Real-Time File or Data Processing
Prototypes & MVPs (fast development, low initial cost)
When to Avoid Serverless?
Think twice if you:
Handle heavy computation or large file processing
Need consistent, low-latency responses
Rely on legacy systems that donโt play well with serverless
