Software Architecture

How do you avoid making your project a big ball of mud? How do you balance a wide range of design concerns and constraints? How do you map customer requirements to working software? This course provides you with the means and methods to face these challenges.

Architecture is often what separates a successful project from chaos. Modern systems place high demands on the architect and the developers.

They should be

  • persistent, and not lose information

  • available and clear load peaks

  • easy to integrate with other systems

  • distributed (sometimes)

  • secure

  • testable

  • easy to expand and manage

Everyone knows the problems, but the traditional solutions that are taught usually lead to big systems with big problems. This course teaches you alternative patterns, missing pieces of the puzzle, and that there are more ways to solve the problems.


We are often told that this course offers things that other courses do not have. This is because we have designed it based on many years of experience in large-scale projects in the industry.

Target audience

Developers and architects who design systems or assume the role of the architect in a project. 

Prerequisites

A couple of years of development. Preferably in an object oriented language (Java, C#, C++). The course, however, is language and platform independent.

My expectation was to get new tools to use and that was fulfilled! Tore is very knowledgeable and was easy to listen to. I liked him. My favourite parts was about the role of the architect, build and deployment and CQRS & Event sourcing.

PARTICIPANT

Even if you know what software architecture is, it is worth to participate in this course. It gives you a clearer picture about software architecture and even if you have experience in this area you will be more experienced, and you can just be better with repetition.

PARTICIPANT

Thorough coverage of different but symbiotic concepts and methods. Also, plenty of references to additional course material. Participating online was a smooth experience, Zoom worked well.
