Serverless computing is a modern cloud-based application architecture, where the application’s infrastructure and support services layer is completely abstracted from the software layer. Any computer program needs hardware to run on, so serverless applications are not “serverless” - they do run on servers - it’s just that the servers are not exposed as physical or virtual machines to the developer running the code.
In a truly serverless architecture paradigm, program code runs on infrastructure hosted and managed by a third party - typically a cloud service - which not only takes care of provisioning, scaling, load balancing and securing the infrastructure, but also installs and manages AWS toolkit, operating systems, patches, serverless architecture framework, code libraries and all necessary support services. As far as the user is concerned, a serverless back-end would scale and load-balance automatically as the application load increases or decreases, all while keeping the application online. The user only needs to pay for the resources consumed by a running application. ...read more!
