Big Bang integration

• Consider a case where you are working for vintage systems where we are developing ecommerce application in Waterfall model
  
• Application is in layered architecture
  
• We have team managers
  • Andy
  • Brian
  • Cathy
    
• Project has to be finished in an year
• Each team works independently for 9 months and finishes the devlopment
  
• Big Bang integrations are error prone, so best solution would be continuos integration (CI).
• The Goal of CI is to inform dev teams about the failures of integration.
• To perform CI different tools started like cruise control and hudson/jenkins
• Need for automated tests/unit tests started at this point.

Agile way of Software Development

• Agile had added smaller and frequent releases, this needs more aggressive automations than CI.
• Expectation:
  • Automated Pipeline which when developer pushes changes
    • Build/Package code
    • Code Quality and Security Issues
    • Automate test executions with System, Performance, Reliablity, Security
    • Report of the Quality of work done yesterday
  • Customer and Internal Releases every 2 weeks
