What Node.js brings: • Full stack development • Skills • Born-on-the-web technologies • micro-services • APIs • Million of modules • Short development cycles https://www.ibm.com/products/sdk-nodejs-compiler-zos Node.js on IBM Z brings: • Free of charge SDK • Optional paid Support • Z modules (VSAM, Db2, CICS) • Lightning-fast access to Z resources • Modernize application and access to IBM Z
- 11. z/OS Vendor • Automated a manual system of issuing product licenses with long-running Node.js application • “The prototype for this modern event-driven solution using Node.js was completed in a single weekend. I can’t think of another language that can achieve so much, across such varied platforms, with so little effort” Major Financial Firm • Developing a Web UI to modernize and move away 3270 “Green Screen” application • Utilizing Node.js REST API support for localized communication with various REST enables assets on their system • Levering Node.js modules that interface with z/OS assets such as mvsutils and ibm_db Zowe • Developed a web user interface that provides a virtual desktop containing a number of apps allowing access to z/OS functions using Node.js on z/OS

- 13. IBM Z Open Automation Tool IBM Z Open Automation Utilities (ZOAU) provides a set of utilities for z/OS which are modelled after similar standard Linux commands but updated to work with z/OS data sets and file systems. Language support for these utilities is extended to allow programmers to use a preferred programming language, such as Java or Python, to develop scripts and automation tools. https://www.ibm.com/docs/en/zoau/1.0.0?topic=why-z-open-automation-utilities
- 14. • Developed in the late 80’s • Scripting but also convertible to executable (can help to Secure assets) • Possible to call C and Assembler code → Performance • Fast community with impressive skills • Start using Python scripting to replace JCL. • Let Python help you with IT Automation
- 15. Ansible is a radically simple IT automation engine automating provisioning, configuration management, application deployment, and many other IT needs. No clients or agents needed $ ansible all -m shell –a “ls”
