Serverless computing in Azure with .NET

Pay-As-You-Go

In serverless computing, you only pay for what you use. The Pay-As-You-Go model is likely to result in cost savings in most cases (remember the underutilized infrastructure), and becomes particularly beneficial in the inconsistent traffic scenarios described in the previous section. The model also means that any speed optimization of your service translates directly into cost savings.

Pay-As-You-Go is also an advantage of any PaaS service, however, most PaaS services do not get as granular in allocating compute power.

While the translation of execution time to cost is a lot more direct in an FaaS environment, it is wise to calculate whether or not the dynamic compute allocation is actually the best pricing model for your application. ...
