Dragon1 defines Application Architecture as 1) the total concept of an application landscape and 2) the total application concept of an organization or chain or network of organizations.
Go to the demo to create an Applications Architecture landscape.
Types of Application Architectures
As with building architecture, an application architecture consists of a specific type or style when there is a certain concept, principle, or element dominant.
Suppose a hospital has many Windows applications, and all these applications are monolithic (meaning they don't consist of replaceable modules), and these two aspects dominate everything and every change. One would say that the type of application architecture for that hospital is a Monolithic Win32 Application Architecture.
Dragon1 suggests that every organization should be familiar with the reference architectures in its industry or branch, as well as the type of application architectures that best fit its size and ambitions.

Overview of Common Application Concepts and Principles
Of course, any organization is unique. That said, every organization utilizes various application concepts, such as Windows 32-bit and monolithic applications.
Below is a summarization of common application concepts.
Many organizations have these concepts as part of their current state application architecture because the IT solution they bought had them embedded.
Common Application Concepts:
- Windows 32 Application
- Monolithic Application
- Three-tier application
Application Architecture Example
Below is an example of application architecture with domains, concepts, and principles. You can, of course, add other elements to it, like building blocks, standards, etc...
Application Architecture: Who is providing the applications?
Applications Landscape with AA Principles Projects
The proof of the pudding is in the eating.
With Application Architecture Principles, we want to support decision-making and guide innovation projects. Therefore, everything that is not compliant with the principles (required by the strategy) blocks the realization of business goals.
Visualizations showing this (as an issue and with a solution) will support decision-making and guide work in projects.
