Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.[1][2]

The architecture of a software system is a metaphor, analogous to the architecture of a building.[3] It functions as the blueprints for the system and the development project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved.

Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. There are two fundamental laws in software architecture:[4][5]

  1. Everything is a trade-off
  2. "Why is more important than how"

"Architectural Kata" is a teamwork which can be used to produce an architectural solution that fits the needs. Each team extracts and prioritizes architectural characteristics (aka non functional requirements) then models the components accordingly. The team can use C4 Model which is a flexible method to model the architecture just enough.[6]

Documenting software architecture facilitates communication between stakeholders, captures early decisions about the high-level design, and allows the reuse of design components between projects.[7]: 29–35 

Software architecture design is commonly juxtaposed with software application design. Whilst application design focuses on the design of the processes and data supporting the required functionality (the services offered by the system), software architecture design focuses on designing the infrastructure within which application functionality can be realized and executed such that the functionality is provided in a way which meets the system's non-functional requirements.

Software architectures can be categorized into two main types: monolith and distributed architecture, each has its own subcategories.[5]

Software architecture tends to become more complex over time. Software architects should use "fitness functions" to continuously keep the architecture in check.[5]

Software architecture activities


Opinions vary as to the scope of software architectures:[8]

There is no sharp distinction between software architecture versus design and requirements engineering (see Related fields below). They are all part of a "chain of intentionality" from high-level intentions to low-level details.[14]: 18 


Software architecture exhibits the following:

Multitude of stakeholders: software systems have to cater to a variety of stakeholders such as business managers, owners, users, and operators. These stakeholders all have their own concerns with respect to the system. Balancing these concerns and demonstrating that they are addressed is part of designing the system.[7]: 29–31  This implies that architecture involves dealing with a broad variety of concerns and stakeholders, and has a multidisciplinary nature.

Separation of concerns: the established way for architects to reduce complexity is to separate the concerns that drive the design. Architecture documentation shows that all stakeholder concerns are addressed by modeling and describing the architecture from separate points of view associated with the various stakeholder concerns.[15] These separate descriptions are called architectural views (see for example the 4+1 architectural view model).

Quality-driven: classic software design approaches (e.g. Jackson Structured Programming) were driven by required functionality and the flow of data through the system, but the current insight[7]: 26–28  is that the architecture of a software system is more closely related to its quality attributes such as fault-tolerance, backward compatibility, extensibility, reliability, maintainability, availability, security, usability, and other such –ilities. Stakeholder concerns often translate into requirements on these quality attributes, which are variously called non-functional requirements, extra-functional requirements, behavioral requirements, or quality attribute requirements.

Recurring styles: like building architecture, the software architecture discipline has developed standard ways to address recurring concerns. These "standard ways" are called by various names at various levels of abstraction. Common terms for recurring solutions are architectural style,[14]: 273–277  tactic,[7]: 70–72  reference architecture and architectural pattern.[16][17][7]: 203–205 

Conceptual integrity: a term introduced by Fred Brooks in his 1975 book The Mythical Man-Month to denote the idea that the architecture of a software system represents an overall vision of what it should do and how it should do it. This vision should be separated from its implementation. The architect assumes the role of "keeper of the vision", making sure that additions to the system are in line with the architecture, hence preserving conceptual integrity.[18]: 41–50 

Cognitive constraints: An observation first made in a 1967 paper by computer programmer Melvin Conway that organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations.[19] Fred Brooks introduced it to a wider audience when he cited the paper and the idea in The Mythical Man-Month, calling it Conway's Law.


Software architecture is an "intellectually graspable" abstraction of a complex system.[7]: 5–6  This abstraction provides a number of benefits:


The comparison between software design and (civil) architecture was first drawn in the late 1960s,[22] but the term "software architecture" did not see widespread usage until the 1990s.[23] The field of computer science had encountered problems associated with complexity since its formation.[24] Earlier problems of complexity were solved by developers by choosing the right data structures, developing algorithms, and by applying the concept of separation of concerns. Although the term "software architecture" is relatively new to the industry, the fundamental principles of the field have been applied sporadically by software engineering pioneers since the mid-1980s. Early attempts to capture and explain software architecture of a system were imprecise and disorganized, often characterized by a set of box-and-line diagrams.[25]

Software architecture as a concept has its origins in the research of Edsger Dijkstra in 1968 and David Parnas in the early 1970s. These scientists emphasized that the structure of a software system matters and getting the structure right is critical. During the 1990s there was a concerted effort to define and codify fundamental aspects of the discipline, with research work concentrating on architectural styles (patterns), architecture description languages, architecture documentation, and formal methods.[26]

Research institutions have played a prominent role in furthering software architecture as a discipline. Mary Shaw and David Garlan of Carnegie Mellon wrote a book titled Software Architecture: Perspectives on an Emerging Discipline in 1996, which promoted software architecture concepts such as components, connectors, and styles. The University of California, Irvine's Institute for Software Research's efforts in software architecture research is directed primarily in architectural styles, architecture description languages, and dynamic architectures.

IEEE 1471-2000, "Recommended Practice for Architecture Description of Software-Intensive Systems", was the first formal standard in the area of software architecture. It was adopted in 2007 by ISO as ISO/IEC 42010:2007. In November 2011, IEEE 1471–2000 was superseded by ISO/IEC/IEEE 42010:2011, "Systems and software engineering – Architecture description" (jointly published by IEEE and ISO).[15]

While in IEEE 1471, software architecture was about the architecture of "software-intensive systems", defined as "any system where software contributes essential influences to the design, construction, deployment, and evolution of the system as a whole", the 2011 edition goes a step further by including the ISO/IEC 15288 and ISO/IEC 12207 definitions of a system, which embrace not only hardware and software, but also "humans, processes, procedures, facilities, materials and naturally occurring entities". This reflects the relationship between software architecture, enterprise architecture and solution architecture.

Architecture activities

There are many activities that a software architect performs. A software architect typically works with project managers, discusses architecturally significant requirements with stakeholders, designs a software architecture, evaluates a design, communicates with designers and stakeholders, documents the architectural design and more.[27]

It's software architect's responsibility to match architectural characteristics (aka non-functional requirements) with business requirements. For example: [5]

There are four core activities in software architecture design.[28] These core architecture activities are performed iteratively and at different stages of the initial software development life-cycle, as well as over the evolution of a system.

Architectural analysis is the process of understanding the environment in which a proposed system will operate and determining the requirements for the system. The input or requirements to the analysis activity can come from any number of stakeholders and include items such as:

The outputs of the analysis activity are those requirements that have a measurable impact on a software system's architecture, called architecturally significant requirements.[31]

Architectural synthesis or design is the process of creating an architecture. Given the architecturally significant requirements determined by the analysis, the current state of the design and the results of any evaluation activities, the design is created and improved.[28][7]: 311–326 

Architecture evaluation is the process of determining how well the current design or a portion of it satisfies the requirements derived during analysis. An evaluation can occur whenever an architect is considering a design decision, it can occur after some portion of the design has been completed, it can occur after the final design has been completed or it can occur after the system has been constructed. Some of the available software architecture evaluation techniques include Architecture Tradeoff Analysis Method (ATAM) and TARA.[32] Frameworks for comparing the techniques are discussed in frameworks such as SARA Report[20] and Architecture Reviews: Practice and Experience.[33]

Architecture evolution is the process of maintaining and adapting an existing software architecture to meet changes in requirements and environment. As software architecture provides a fundamental structure of a software system, its evolution and maintenance would necessarily impact its fundamental structure. As such, architecture evolution is concerned with adding new functionality as well as maintaining existing functionality and system behavior.

Architecture requires critical supporting activities. These supporting activities take place throughout the core software architecture process. They include knowledge management and communication, design reasoning and decision-making, and documentation.

Architecture supporting activities

Software architecture supporting activities are carried out during core software architecture activities. These supporting activities assist a software architect to carry out analysis, synthesis, evaluation, and evolution. For instance, an architect has to gather knowledge, make decisions, and document during the analysis phase.

Software architecture topics

Software architecture description

Main article: Software architecture description

Software architecture description involves the principles and practices of modeling and representing architectures, using mechanisms such as architecture description languages, architecture viewpoints, and architecture frameworks.

Architecture description languages

Main article: Architecture description language

An architecture description language (ADL) is any means of expression used to describe a software architecture (ISO/IEC/IEEE 42010). Many special-purpose ADLs have been developed since the 1990s, including AADL (SAE standard), Wright (developed by Carnegie Mellon), Acme (developed by Carnegie Mellon), xADL (developed by UCI), Darwin (developed by Imperial College London), DAOP-ADL (developed by University of Málaga), SBC-ADL (developed by National Sun Yat-Sen University), and ByADL (University of L'Aquila, Italy).

Architecture viewpoints

Main article: View model

4+1 architectural view model.

Software architecture descriptions are commonly organized into views, which are analogous to the different types of blueprints made in building architecture. Each view addresses a set of system concerns, following the conventions of its viewpoint, where a viewpoint is a specification that describes the notations, modeling, and analysis techniques to use in a view that expresses the architecture in question from the perspective of a given set of stakeholders and their concerns (ISO/IEC/IEEE 42010). The viewpoint specifies not only the concerns framed (i.e., to be addressed) but the presentation, model kinds used, conventions used and any consistency (correspondence) rules to keep a view consistent with other views.

Architecture frameworks

Main article: Architecture framework

An architecture framework captures the "conventions, principles and practices for the description of architectures established within a specific domain of application and/or community of stakeholders" (ISO/IEC/IEEE 42010). A framework is usually implemented in terms of one or more viewpoints or ADLs.

Architectural styles and patterns

An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. Architectural patterns are often documented as software design patterns.

Following traditional building architecture, a 'software architectural style' is a specific method of construction, characterized by the features that make it notable" (architectural style).

An architectural style defines: a family of systems in terms of a pattern of structural organization; a vocabulary of components and connectors, with constraints on how they can be combined.[37]

Architectural styles are reusable 'packages' of design decisions and constraints that are applied to an architecture to induce chosen desirable qualities.[38]

There are many recognized architectural patterns and styles, among them:

Some treat architectural patterns and architectural styles as the same,[39] some treat styles as specializations of patterns. What they have in common is both patterns and styles are idioms for architects to use, they "provide a common language"[39] or "vocabulary"[37] with which to describe classes of systems.

Software architecture and agile development

Main article: Agile development

There are also concerns that software architecture leads to too much big design up front, especially among proponents of agile software development. A number of methods have been developed to balance the trade-offs of up-front design and agility,[40] including the agile method DSDM which mandates a "Foundations" phase during which "just enough" architectural foundations are laid. IEEE Software devoted a special issue to the interaction between agility and architecture.

Software architecture erosion

Software architecture erosion refers to a gradual gap between the intended and implemented architecture of a software system over time.[41] The phenomenon of software architecture erosion was initially brought to light in 1992 by Perry and Wolf alongside their definition of software architecture.[3]

Software architecture erosion may occur in each stage of the software development life cycle and has varying impacts on the development speed and the cost of maintenance. Software architecture erosion occurs due to various reasons, such as architectural violations, the accumulation of technical debt, and knowledge vaporization.[42] A famous case of architecture erosion is the failure of Mozilla Web browser.[43] Mozilla is an application created by Netscape with a complex codebase that became harder to maintain due to continuous changes. Due to initial poor design and growing architecture erosion, Netscape spent two years redeveloping the Mozilla Web browser, showing how important it is to manage architecture erosion to avoid extensive repair efforts, time and cost losses.

Architecture erosion can decrease software performance, substantially increase evolutionary costs, and degrade software quality. Various approaches and tools have been proposed to detect architecture erosion. These approaches are primarily classified into four categories: consistency-based, evolution-based, and defect-based, and decision-based approach.[41] Besides, the measures used to address architecture erosion contains two main types: preventative and remedial measures.[41]

Software architecture recovery

Main article: Software architecture recovery

Software architecture recovery (or reconstruction, or reverse engineering) includes the methods, techniques, and processes to uncover a software system's architecture from available information, including its implementation and documentation. Architecture recovery is often necessary to make informed decisions in the face of obsolete or out-of-date documentation and architecture erosion: implementation and maintenance decisions diverging from the envisioned architecture.[44] Practices exist to recover software architecture as static program analysis. This is a part of the subjects covered by the software intelligence practice.

Related fields


Main article: Software design

Architecture is design but not all design is architectural.[1] In practice, the architect is the one who draws the line between software architecture (architectural design) and detailed design (non-architectural design). There are no rules or guidelines that fit all cases, although there have been attempts to formalize the distinction. According to the Intension/Locality Hypothesis,[45] the distinction between architectural and detailed design is defined by the Locality Criterion,[45] according to which a statement about software design is non-local (architectural) if and only if a program that satisfies it can be expanded into a program that does not. For example, the client–server style is architectural (strategic) because a program that is built on this principle can be expanded into a program that is not client–server—for example, by adding peer-to-peer nodes.

Requirements engineering

Main article: Requirements engineering

Requirements engineering and software architecture can be seen as complementary approaches: while software architecture targets the 'solution space' or the 'how', requirements engineering addresses the 'problem space' or the 'what'.[46] Requirements engineering entails the elicitation, negotiation, specification, validation, documentation, and management of requirements. Both requirements engineering and software architecture revolve around stakeholder concerns, needs, and wishes.

There is considerable overlap between requirements engineering and software architecture, as evidenced for example by a study into five industrial software architecture methods that concludes that "the inputs (goals, constraints, etc.) are usually ill-defined, and only get discovered or better understood as the architecture starts to emerge" and that while "most architectural concerns are expressed as requirements on the system, they can also include mandated design decisions".[28] In short, required behavior impacts solution architecture, which in turn may introduce new requirements.[47] Approaches such as the Twin Peaks model[48] aim to exploit the synergistic relation between requirements and architecture.

Other types of 'architecture'

Main articles: Computer architecture, Systems architecture, and Enterprise architecture

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. It essentially shifts server management responsibilities from developers to cloud service providers. This allows businesses to run their backend code on cloud infrastructure, eliminating the need for physical server management. The event-driven approach of serverless architecture relies on small, task-specific functions that are executed on-demand. These functions are known as Function as a Service (FaaS), and they offer cost-efficiency through a pay-as-you-go billing model and dynamic resource scaling based on application demand.[49][better source needed]
Systems architecture
The term systems architecture has originally been applied to the architecture of systems that consist of both hardware and software. The main concern addressed by the systems architecture is then the integration of software and hardware in a complete, correctly working device. In another common – much broader – meaning, the term applies to the architecture of any complex system which may be of a technical, sociotechnical or social nature.
Enterprise architecture
The goal of enterprise architecture is to "translate business vision and strategy into effective enterprise". Enterprise architecture frameworks, such as TOGAF and the Zachman Framework, usually distinguish between different enterprise architecture layers. Although terminology differs from framework to framework, many include at least a distinction between a business layer, an application (or information) layer, and a technology layer. Enterprise architecture addresses among others the alignment between these layers, usually in a top-down approach.
