Despite the name, serverless computing still uses servers. This means companies can access the exact resources they need whenever they need them, rather than paying for server space and computing power they only need occasionally. If servers reach maximum load and capacity in-house, something has to give before adding new services.

This will not only reduce the overall latency in displaying the user-feeds to users but will also prevent re-computation of user-feeds.
