Nowadays, developers everywhere are introduced to an application development trend called serverless computing. The trend isn't new but rather an evolution culminating from a number of development methodologies, including service-oriented architecture (SOA), distributed cloud computing, Platform-as-a-service (PaaS) and Containers/Microservices. A key defining element of serverless computing is the serverless application's logic that combines custom-developed code and 3rd-party service functionality.
