The document outlines a framework developed by National Instruments for defining, provisioning, monitoring, and controlling cloud-based systems using Java and SSH, primarily supporting AWS. It features an XML-based model for automation infrastructure as code, allowing for dynamic scaling and efficient deployment of services and applications. The framework integrates with a third-party monitoring service and emphasizes repeatability, rapid provisioning, and resilience in system management.

PIE - The Programmable Infrastructure Environment
- 1. Ernest Mueller Peco Karayanev National Instruments theagileadmin.com
- 2. a framework to define, provision, monitor, and control cloud-based systems written in Java, uses SSH as transport, currently supports Amazon AWS (Linux and Windows) takes an XML-based model from source control and creates a full running system
- 3. model driven automation infrastructure as code DevOps dynamic scaling agility
- 5. XML descriptions of the system as ‘specs’ system (top level) environment (instance of a system) role (“tier” within a system) image (specific base box config) service (specific software or application) commands (for various levels) templates (files to be parsed)
- 8. uses Apache Zookeeper (part of Hadoop project) the registry contains information about the running system specific addressing scheme: /fcc/test1/external-services/2/tomcat [/<system>/<environment>/<role>/<instance>/<service>] pie registry.register /fcc/test1/external-services/2 pie registry.bind /fcc/test1 pie registry.list /fcc/test1

- 12. integrated with third party SaaS monitoring provider Cloudkick systems register with Cloudkick as they come online and immediately have appropriate monitors applied based on tags set from the model
- 14. repeatable – no manual errors reviewable – model in source control rapid – bring up, install, configure, and test dozens of systems in a morning resilient – automated reconfiguration to swap servers (throw away infrastructure)
- 15. Azure support Faster performance Robust runtime (parallel, transactional, event-driven) Scripting ( search, map, regex, orchestration semantics) Data in the Model
