How to install Serverless toolkit in RHEL 8 by Raj Gupta

Serverless is your toolkit for deploying and operating serverless architectures. Focus on your application, not your infrastructure. Build faster with serverless architectures: ------------------------------------------------------------------ Develop, test and deploy in a single environment, to any cloud provider. You don’t have to provision infrastructure or worry about scale. Serverless teams cut time to market in half.
