The dream of serverless is simple: focus only on your code and let the provider handle everything else. No servers to patch, no OS to manage, and no scaling configuration to tweak.
However, the reality is more complex:
**The Pros:**
* **Absolute Scalability:** It handles 1 user or 1 million users with ease.
* **Pay-per-execution:** You only pay when your code actually runs.
* **Reduced Ops Load:** Your team focuses on features, not maintenance.
**The Cons:**
* **Cold Starts:** Initial latency when an idle function is triggered.
* **Vendor Lock-in:** Moving a complex serverless app between providers is incredibly difficult.
* **Debugging Hurdles:** Monitoring distributed functions across a cloud environment is notoriously tricky.
Serverless isn't a silver bullet, but for the right workloads, it’s the most efficient way to build.
