3 Open API Access to Mainframe API Enablement Strategy Build and deliver mainframe services from CA as a set of microservice APIs Use-case driven prioritization of mainframe microservice creation Leverage existing CA mainframe solutions to create microservice APIs Build use-case driven APIs where needed API Gateway to deliver API scalability, consistency, and security API Catalog to consolidate, visualize and make APIs accessible to the developers 3

6 Let s Listen Project Brightside What are developers asking for with the mainframe? 6

7 7 Command Line interface - CLI

8 CLI Project Brightside Why a CLI? A CLI is both a UI and an API Developer-friendly UX Scriptability Examples: git, Linux (Bash), SonarScanner, AWS CLI, Google Cloud CLI

9 The Cloud Comparison AWS Google Cloud Microsoft Azure IBM BlueMix Pivotal CloudFoundry The AWS CLI puts the icing on the cake by tying control of all those services together into one simple command line interface. It cuts out the user-friendly (but timeconsuming, according to some) step of interacting with the system through a Graphical User Interface (GUI). What s common amongst all of them? Why? With it, you can control services manually or automate them with powerful scripts. 9

10 Common Use Cases for a CLI CLI use in any terminal CLI use in shell scripts CLI use in CI/CD CLI use in any IDE CLI use in Source Build tools 10

11 Gradle / Angular CLI Example "scripts": { "ng": "ng", "start": "ng serve", "builddev": "ng build", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" } 11

12 Shell Script / Docker CLI Example #!bin/bash $ docker run -a stdin -a stdout -i -t ubuntu /bin/bash $ docker run -a stdin -a stdout -a stderr ubuntu /bin/ls 12
