Companies are always worried about infrastructure costs and provisioning of servers when their Functions call rate become very high. Serverless providers like Microsoft Azure are a perfect solution for situations like this as they aim to provide an event-based serverless compute experience to aid in faster app development.
It is event-driven, and developers no longer have to rely on the ops to test their code. They can quickly run, test and deploy their code without getting tangled in the traditional workflow. Serverless Computing automatically scales your application. With each individual trigger, your code will run parallel to it, thereby reducing your workload and saving time in the process. When the code is not running, you don’t have to pay anything.
