Stages of database applications development

Development

The development level service characterizes by:
  • 8/5 monitoring and availability
  • DBA consultancy by e-mail
  • limited database space (maximum 500MB)

To have an account on development level service:

  • have a CERN NICE account
  • fill the form provided by IT/DES on the web

Integration

The integration level service characterizes by:
  • 8/5 monitoring and availability
  • DBA consultancy by e-mail, phone for optimize application
  • Dedicated node for testing application performance with expected data volume and concurrency

The integration level goal:

  • test application's behavior under the workload similar to the expected production one

The application development team's role is:

  • to provide workload simulating tools, generating the traffic as similar to the production conditions as possible
  • to ask for a slot time (usually week) for tests
  • to run tests

Production

The production level service characterizes by:
  • 24/7 monitoring and availability
  • Backups every 10 minutes
  • Limited number and scheduled planned interventions

To move to production level service is necessary to provide:

  • database schema
  • security plans (use of reader/writer or roles)
  • data volume expected for next 2 years
  • expected simultaneous connections
  • reference workload (script) and reference running time of it
  • if (volume expected > 50 GB) or (simultaneous connections > 50) then should pass also a test on integration phase
