3. Objectives Identify overall project objectives:
Fast architecture delivery
Secure architecture: by design
Reproducible builds
Secure lifecycle for code and architecture components
Infrastructure as code, semantically managed
Constant updates through CI for architecture as code
Version control system for each component: OSGi artifacts, general code, architecture description, building systems…
Self healing architecture

4. Project Scope
Define a simple architecture with the following features:
Source code should be automatically sent to Test and Production system as a unit
Repositories should be automatically managed and linked to the registry
Artifacts should versioned and each build should be reproducible
Units of deployment (Docker) should be formed by units of functionally (OSGi)
Service composition should be made through the composition of units of deployment
Each unit of deployment should be self-contained, and immutable in every possible location
Permission systems should be tailored to specific apps, while no container will run with administrative privileges
Each instance should be recreated exactly as every other one created from the same process, resisting restart events
May require more than one slide

5. Deliverables Open-source self building architecture
Production pipeline as code – CI for each component and version controlled pipes
Metric providers and collectors for Java apps

6. Success Factors
Each element must be automatically built and have its building pipeline controlled by a version control system
Each element should be hardened and resist security tests
No software component should be provided by code – only from the warehouse (Artifactory)
Final criteria: if a bomb explodes the data center, the architecture should be able to build itself in a second location
