Serverless platforms automatically create as many function instances as needed when traffic surges. Unlike traditional servers that require manual scaling or preconfigured capacity, serverless responds in real time. A sudden viral post or flash sale won’t crash the system. Each request is handled independently, preventing bottlenecks. Once traffic subsides, resources vanish just as quickly. This elasticity is nearly impossible to replicate with fixed infrastructure.
Applications remain available even during extreme demand spikes. Businesses avoid downtime during critical moments.
This dynamic scaling enables confidence in launching global campaigns without infrastructure anxiety. Teams can focus on growth instead of capacity planning.
Serverless can scale from zero to thousands of requests per second automatically.
