Modernization of a productive application to current software components.
An existing internal application will be converted to modern and currently secure components as part of the contract.
Struts-1, Spring 3, Hibernate 3, and similar outdated systems will be replaced. Stability in production had to be guaranteed under all circumstances for the changeover duration.
Details
- Creation and implementation of JUnit tests
- Replacing outdated APIs with new versions
- Conversion of the built environment to Docker / docker-compose
- Conversion of the production environment to Docker
- General maintenance and care
- Guaranteeing production stability
Activities
