Serverless computing is a model of cloud computing in which the service provider operates the server and dynamically manages the allocation of computing resources such as processing, memory and storage. The provider bases pricing on the resources applications actually consume, rather than the tradition pricing model that requires the user to purchase resources before using them. Serverless computing simplifies enterprise software development by concealing administrative tasks such as capacity planning, maintenance and scaling from the developer. Developers can also combine serverless computing traditional code deployment styles.

Serverless computing is a cloud-computing model in which the cloud provider dynamically manages the allocation of computing resources. AWS Lambda is a serverless computing platform that Amazon provides as part of Amazon Web Services (AWS). It’s also event-driven, meaning that Lambda only executes code in response to events and automatically manages the computing resources that the code requires. These capabilities allow developers to focus on an application’s business logic, rather than provisioning resources and managing access control.

Kubernetes can manage complex sets of software containers by itself, but it also creates its own configuration and management challenges. Knative is an extension of Kubernetes that eliminates the need for developers to perform these tasks and also serverless capabilities to Kubernetes. It runs on top of Kubernetes, allowing Knative to manage a large number of containers in enterprise software development. Google developed Knative as an open-source platform in collaboration with other companies such as IBM, Pivotal, Red Hat and SAP.

Kubeless is a Functions-as-a-Service (FaaS) platform that runs with Kubernetes. It’s entirely open-source, so it has no affiliation with any commercial organization. Kubeless is a serverless framework that allows developers to deploy small units of code without considering its underlying infrastructure. This capability means that Kubeless can leverage Kubernetes resources to perform tasks vital to enterprise software development such as API routing, auto-scaling, monitoring and troubleshooting.
