The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
The roofline model is an intuitive visual performance model used to provide performance estimates of a given compute kernel or application running on multi-core, many-core, or accelerator processor architectures, by showing inherent hardware limitations, and potential benefit and priority of optimizations.
Computer architecture Computer architecture targets the internal structure of a computer system, in terms of collaborating hardware components such as the CPU – or processor – the bus and the memory. Serverless architecture Serverless architecture is a cloud computing paradigm that is often misunderstood as being server-free.
For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2] In the case of an application program or a computer video game , the most relevant layer is the operating system, so it can be called a platform itself (hence the term cross-platform for software that can be ...
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
The Java Platform, Enterprise Edition architecture is a layered reference architecture which provides a template solution for many enterprise systems developed in Java. Examples of implementing frameworks include Glassfish and Wildfly. The IBM Insurance Application Architecture [3] is a reference architecture for the Insurance domain.
Applications are said to "run on" or "run on top of" the resulting platform. For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware, database, and applications. [2]
Applications architecture strategy involves ensuring the applications and the integration align with the growth strategy of the organization. If an organization is a manufacturing organization with fast growth plans through acquisitions, the applications architecture should be nimble enough to encompass inherited legacy systems as well as other large competing systems.
