Software application architecture is an interesting and broadly discussed topic. In this presentation, I am discussing N-Tier application architecture. Going to investigate: What is architecture? Kinds of N-Tier application architecture and its advantage and disadvantage.
There is also a very basic quiz at the end of the session.

    6. 6. Architecture?? Standard definition: Noun - The art or practice of designing and constructing buildings. - The style of a building with regard to a specific period, place, or culture. "Architecture is that great living creative spirit which from generation to generation, from age to age, proceeds, persists, creates, according to the nature of man, and his circumstances as they change. That is really architecture.“ - Frank Lloyd Wright on ArchitectureThe Trusted Technology Partner in Business InnovationProducts | Consulting Services | Managed Services
    7. 7. Software Architecture?? “Software architecture encompasses the set of significant decisions about the organization of a software system including the selection of the structural elements and their interfaces by which the system is composed; behavior as specified in collaboration among those elements; composition of these structural and behavioral elements into larger subsystems; and an architectural style that guides this organization. Software architecture also involves functionality, usability, resilience, performance, reuse, comprehensibility, economic and technology constraints, tradeoffs and aesthetic concerns.” - Philippe Kruchten, Grady Booch, Kurt Bittner, and Rich Reitman derived and refined a definition of architecture based on work by Mary Shaw and David Garlan (Shaw and Garlan 1996) What Software Architecture Is Not?  Lower-level design (e.g. design of component internals and algorithms) and implementation,  The information (or data) model,  Architecture of the physical system, including processors, networksThe Trusted Technology Partner in Business InnovationProducts | Consulting Services | Managed Services
    8. 8. What if we don’t care about Architecture?The Trusted Technology Partner in Business InnovationProducts | Consulting Services | Managed Services
    9. 9. Why is Architecture Important?  Like any other complex structure, software must be built on a solid foundation  Failing to consider key scenarios, design for common problems, or the long term consequences of key decisions can put application at risk  Modern tools and platforms help to simplify the task of building applications, but they do not replace the need to design your application carefully  The risks exposed by poor architecture includes:  Unstable application  Unable to support existing or future business requirements  Difficult to deploy or manage in a production environmentThe Trusted Technology Partner in Business InnovationProducts | Consulting Services | Managed Services
    10. 10. The Goals of Architecture 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?The Trusted Technology Partner in Business InnovationProducts | Consulting Services | Managed Services
