• Master nodes:

  • 192.168.0.13 cis-cose-master-01
  • 192.168.0.8 cis-cose-master-02
  • 192.168.0.12 cis-cose-master-03

• Slaves:

  • 192.168.0.9 cis-cose-slave-01
  • 192.168.0.7 cis-cose-slave-02
  • 192.168.0.10 cis-cose-slave-03
  • 192.168.0.11 cis-cose-slave-04

• Public Slave using for security/access reasons:

  • 192.168.0.6 cis-cose-slave-public-01 (floating IP: 128.107.5.125)

• Load Balancer:

  • 192.168.0.5 cis-cose-lb-01

• VPN-server:

  • 192.168.0.2 cis-cose-vpn-01 (floating IP: 128.107.5.123)

Application Architecture

Data Source

GitHub hosts open-source software projects. This is the main source of data.

The data is gathered via:

• GitHub API
  • User Level data - Username, Company the user works for, # of Followers, # of Following, # of Public Repos,# of Contributions, Repos contributed to, attributes etc.
  • Repository Level data - Watchers, Forks, Commit, Comments, Response time, unique Contributors and collaborators
• Google BigQuery
  • Events timeline data - This is used to capture timeline of Events performed by a User on a Repository.
