AWS Serverless Application Model vs. Azure Functions vs. OpenShift Cloud Functions vs. Serverless Stack Comparison Chart

AWS Serverless Application Model (AWS SAM) consists of two parts: AWS SAM templates and the AWS Serverless Application Model Command Line Interface (AWS SAM CLI). AWS SAM templates provide a short-hand syntax, optimized for defining Infrastructure as Code (IaC) for serverless applications. An extension of AWS CloudFormation, you deploy AWS SAM templates directly to CloudFormation, benefiting from its extensive IaC support on AWS. The AWS SAM CLI is a developer tool that puts AWS SAM features at your fingertips. Use it to quickly create, develop, and deploy serverless applications. Some of the many features of AWS SAM include AWS Serverless Application Model Accelerate (AWS SAM Accelerate), which speeds up local development and cloud testing, and AWS SAM CLI integrations, extending AWS SAM to other tools such as the AWS Cloud Development Kit (AWS CDK) and Terraform. Streamline your serverless development cycle, quickly and efficiently taking an idea to production.

Red Hat Openshift Cloud Functions (OCF) is a FaaS - Function as a Service that can be deployed on Openshift and is based out of Knative a FaaS project in the Kubernetes community. It will enable developers to run code without needing to know anything about the underlying platform specifics. Developers need access to services faster, deploying backend services, platforms or applications can be time-consuming and tedious. This also means developers should not be restricted to any certain language or framework but also to create business value quickly and enhance services by way of FaaS i.e. Function as a Service that can scale a small unit of custom code while depending on other third-party/backend services. Serverless is an architectural model that provides an event-driven way to implement distributed applications that can auto-scale on demand.
