What is Serverless Computing?
Despite the name, serverless computing does not mean there are no servers. It simply means developers do not have to manage, provision, scale, or patch servers themselves. The cloud provider dynamically manages the underlying infrastructure and runs your code in stateless, event-driven containers.
Key Advantages of Serverless
- No Server Management: Zero administrative overhead allows teams to focus entirely on writing business logic.
- Automatic Scaling: Serverless applications scale up instantly to handle high traffic spikes and scale down to zero when idle.
- Pay-Per-Execution: You are charged only for the CPU time and memory used while your code runs, resulting in massive cost savings.
Ideal Use Cases
Serverless architecture is perfect for building RESTful APIs, processing files and uploads (e.g., resizing images), running background cron jobs, and orchestrating event-driven workflows.
Conclusion
Serverless computing lowers infrastructure costs and accelerates release cycles. Choosing serverless components will streamline your engineering velocity.
