Many large companies like Coca- Cola and The Seattle Times are already leveraging the benefits of serverless computing to help trigger code in response to a series of pre-defined events. This helps them to manage their fleet of servers without the threat of overhead costs.
One of the main attractions of serverless computing is that it is a ‘pay as you use’ model. You just need to pay for the runtime of your function – the duration your code is executed and the number of times it’s been triggered. You don’t have to incur the cost of unutilized functions as seen in a cloud computing model where even ‘idle’ resources must be paid for.
