Implementing Modern Architecture

To be a successful architect, one needs to know the pros and cons of different architectures and under what conditions they are applied in a project. In addition, a good knowledge of the development process and project support in production is also very valuable.

Fenomenalt kurs. Obligatorisk for alle systemarkitekter.

Veldig kompetente kursledere, mange gode «real life» eksempler på hvordan man drar nyte av arkitektursprinsippene som var presentert.

Kursholderne var flinke til å relatere det teoretiske innholdet til praktiske eksempler og tilpasse dette til vårt forventningsnivå.

Veldig bra kurs, vil absolutt anbefale det for andre

The course had a good pace and covered almost only interesting themes

An extremely helpful and informative course, especially in conjunction with appropriately prepared material.
