Overview
Background
The focus of this project is end of life for the EUCLID application tier, this includes:
- Operating system (RedHat 6, end date December 2020)
- Java (Java 6, end date 2018)
License cost should be taken into account and where possible Open Source should be used. The Student Record System vendor (Tribal) has confirmed support for Centos, upgrading to Centos (Open Source) will provide an added saving on license costs. Open JDK will be investigated as an alternative.
With the Student Area business calendar in mind including the annual SITS Upgrade, this work should be scheduled for summer 2019. The SITS Upgrade is taking place in Live in February 2020. Therefore, the move to Centos 7 needs to take place before December 2019 in order to ensure that SITS can run in the new environment for at least 2 months before the SITS Upgrade.
Scope
In Scope:
- Operating system upgrade of the EUCLID application tier
- Upgrade Java
- This will initially be carried out in the DUST Environment in order to test if this Upgrade works for the Integrator. There is a noted risk. In case the upgraded Java would not work for the integrator, it it would be managed on its own server with an old Java version with improved security on the server as there is no time/budget to rewrite the integrator.
- Use of automated deployment techniques where possible for speed and consistent deployment
Out of scope
- Student record components outside of the EUCLID/SITS application tier
