Low cost

In serverless computing, developers are billed only for the time that the function is running, unlike IaaS and PaaS, which are billed 24/7 for each server. This is good for companies with a huge setup of apps, APIs, or microservices that are currently running 24/7 and using resources 100 percent of the time, whether they are required or not. But with serverless, instead of running the application 24/7, we can execute functions on demand and share the resources, so we can reduce the idle time substantially and still make the application run faster.
