Serverless computing platforms give developers a rapid way to build APIs without servers. OpenWhisk supports automatic generation of REST API for actions exposed by API Gateway. When the capabilities provided by the API Gateway do not cover all usecases you have for an API - such as publishing it in a developer portal or performing advanced mapping, transformation, validation, you can migrate to the API Connect service.
Earlier this year, the wsk api command was introduced as the replacement for the wsk api-experimental command. The wsk api-experimental command is now deprecated and will be withdrawn at the end of July, 2017. On August 1st, all APIs created with the wsk api-experimental command will be removed.
The OpenWhisk CLI commands for API Gateway functionality labeled "wsk api-experimental" have been replaced with the new command "wsk api".
As your app gets more users and traffic how do you scale its components to handle the additional load?
