Sample Pipeline

Requirements for system to store code

• Common Server/Application/Sytem to store the code from muliple developers
• Version should be maintained for every change.
• Multiple users should be allowed to work on same files/code
• Any system which satisfies above three points is a Version Control System
• VCS:
  • CVS
  • VSS
  • SVN
  • ClearCase
  • GIT

Architectures of VCS

• Client-Server Architecture:

  • Connected:
    • Clients should be connected to servers all the time
    • Administrators are required to take backups and also to replicate to multi-sites
    • Network connectivity issues could disrupt developers in doing the work

  

  • Dis-Connected:
    • Clients needed to be connected to servers only for getting the latest code or to submit work. Clients can work in offline mode
    • Administrators are required to take backups and also to replicate to multi-sites

• Distributed Architecture:

  • Whole copy of code is present on every node (client).
  • Backup of the Code is one more node
  • Other site is one more node
  • Git is a Distributed Version Control System.
