Serverless computing is a cloud-computing execution model in which the cloud provider runs the server, and dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity. The IT giants offers very rich and powerful solutions for serverless, from AWS Lambda to Google Cloud Fuctions with very small specificities. Serverless usage is increasing in different fields, from automatic testing to e-commerce, MABL is one the innovating projects using Google's serverless architecture
