Application architecture is the organizational design of an entire software application, including all sub-components and external applications interchanges. There are several design patterns that are used to define this type of architecture, and these patterns help to communicate how an application will complete the necessary business processes as defined in the system requirements.
Application architecture is a challenging topic, as evidenced by the wide variety of books, articles, and white papers on the subject. It is still too hard for developers and architects to understand architecture and design best practices for the.NET platform.

A software application is a system designed to automate specific tasks in a logical manner to satisfy a set of requirements. It relies on underlying operating systems and databases to store and perform tasks within the application. The application architecture is the blueprint that defines how the program will interact with servers and components within the domains of application layers.
With the expansion of interoperability within software, modular components have been created that specialize in specific areas of business processes within an application. The architecture defines all of the components within the design and how they will communicate within the application. This definition includes all layers of an application.
There are three main areas of control within all applications: the presentation layer, the business layer, and the data access layer. Each domain within an application has a specific responsibility that, when joined with the other layers, satisfy the underlying business requirements of an application.
In information systems, applications architecture or application architecture is one of several architecture domains that form the pillars of an enterprise architecture (EA).[1][2]
An applications architecture describes the behavior of applications used in a business, focused on how they interact with each other and with users. It is focused on the data consumed and produced by applications rather than their internal structure. In application portfolio management, the applications are usually mapped to business functions and to application.

The applications architecture is specified on the basis of business and functional requirements. This involves defining the interaction between application packages, databases, and middleware systems in terms of functional coverage. This helps identify any integration problems or gaps in functional coverage. A migration plan can then be drawn up for systems which are at the end of the software life cycle or which have inherent technological risks.
Applications architecture tries to ensure the suite of applications being used by an organization to create the composite architecture is scalable, reliable, available and manageable.
Applications architecture means managing how multiple applications are poised to work together. It is different from software architecture, which deals with technical designs of how a system is built.[citation needed]
One not only needs to understand and manage the dynamics of the functionalities the composite architecture is implementing but also help formulate the deployment strategy and keep an eye out for technological risks that could jeopardize the growth and/or operations of the organization.[citation needed]
Strategy[edit]
Applications architecture strategy involves ensuring the applications and the integrations 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.
Hadoop Application Architecture PdfPatterns[edit]
Applications can be classified in various types depending on the applications architecture pattern they follow.

A 'pattern' has been defined as: 'an idea that has been useful in one practical context and will probably be useful in othersâ.
To create patterns, one needs building blocks. Building blocks are components of software, mostly reusable, which can be utilized to create certain functions. Patterns are a way of putting building blocks into context and describe how to use the building blocks to address one or multiple architectural concerns.
An application is a compilation of various functionalities, all typically following the same pattern. This pattern defines the application's pattern.
Applications typically follow one of the following industry-standard applications architecture patterns:
The right applications pattern depends on the organization's industry and use of the component applications.An organization could have a mix of multiple patterns if it has grown both organically and through acquisitions.
Application architect[edit]
The Application architect is a lead or technical manager in the computer programming team who is specialized in the application built and the technologies used.
Knowledge domains[edit]
Tasks[edit]
An applications architect is a master of everything application-specific in an organization.An applications architect provides strategic guidelines to the applications maintenance teams by understanding all the applications from the following perspectives:
The above analysis will point out applications that need a range of changes â from change in deployment strategy for fragmented applications to a total replacement for applications at the end of their technology or functionality lifecycle.
Functionality footprint[edit]
Understand the system process flow of the primary business processes. It gives a clear picture of the functionality map and the applications footprint of various applications across the map.
Many organizations do not have documentation discipline and hence lack detailed business process flows and system process flows. One may have to start an initiative to put those in place first.
Create solution architecture guidelines[edit]
Every organization has a core set of applications that are used across multiple divisions either as a single instance or a different instance per division. Create a solution architecture template for all the core applications so that all the projects have a common starting ground for designing implementations.
Basic Application Architecture
The standards in architecture world are defined in TOGAF, The Open Group Architecture Framework which covers all components of EA, including application as well as technology architecture.
Types Of Application Architecture
There are also other standards to consider, depending on the level of complexity of the organization:
