What is Software Architecture?

• History• The comparison between software design and (civil) architecture was first

drawn in the late 1960s• Software architecture as a concept has its origins in the research of Edsger

Dijkstra in 1968 and David Parnas in the early 1970s• The term software architecture became prevalent only in the 1990s

Systems should be designed with consideration for the user, the system (the IT infrastructure), and the business goals

Design

The Goals of Architecture• The primary goal of the architecture is to identify requirements that

affect the structure of the application• Consider the following high level concerns when thinking about

software architecture:• How will the users be using the application?• How will the application be deployed into production and managed?• What are the quality attribute requirements for the application, such as

security, performance, concurrency, internationalization, and configuration?• How can the application be designed to be flexible and maintainable over time?• What are the architectural trends that might impact your application now or

after it has been deployed?

Who is a Software Architect?

“Gateway between stakeholder and developer team”

“Not a must but could become technical dictator”

“Obviously it’s technical lead”

Architecture vs Design• All architecture is design, but not all design is architecture

Software Architecture Patterns• Architecture patterns help define the basic characteristics and

behavior of an application• As an architect, you must always justify your architecture decisions,

particularly when it comes to choosing a particular architecture pattern or approach.• Choosing the right architecture pattern is critical, because once an

architecture is in place, it is very hard (and expensive) to change

Software Architecture Trend

From Developer to ArchitectDeveloper• More into coding and converned about best way

to solve a particular problem• Usually no need to sell his way of working (which

is often down to coding)• No involvement in strategic decisions• Tend to recommend a tool/language he is most

familiar with• Goes for best technical solution• Less scope for delegation• Responsible for implementation• Heavily involved in coding• Finds a solution to a problem according to design• Soft skill less important• Often works in single project

Architect• See big picture of the system before it is built• Need to convince (or sell) stakeholders about vision,

ideas and recommendation• Often recommends and selects tools for strategic

implementation• Evaluates and compares all available options and

selects one which is best for business• Goes for best fit solution for the organization• More scope for delegation• Defines general layout of the system• Not heavily involved in coding• Finds the definition of actual problem and suggest

design to solve it• Soft skill is more important• Often works in multiple projects across the

organization
