What is software architecture? Tools, patterns and design

Much of what you do daily, from using your cell phone to sending email, depends on your system's software architecture. We often take software architecture for granted, and many people don't even know what it is or how it can be used.


Much of what we know and use is impossible without software architecture, but what is it?


Software architecture enables innovation within an organization. The architecture used within the software must be of high quality, capable of performing a large amount of work, ready to use when needed, and cost-effective.



1. Definition of software architecture 

Software Architecture & Design Introduction


Software architecture is simply the organization of the system. This organization contains all the components, how they interact, the environment in which they operate, and the principles used to design the software. In many cases, it may also include the evolution of software into the future.


The software architecture is designed with one or more specific missions in mind. That mission must be accomplished without interfering with the mission of other tools and devices. The behavior and structure of the software influence essential decisions and must be properly rendered and built for the best results.



2. Why is software architecture so important?

The key to success when building something is to understand the basics correctly. Whether you're building a house or making pizza, if the original part doesn't work, you'll have to start over. There is no other way.


The same is true for building web applications. The architecture is basic and should be carefully considered later to avoid major design changes and code refactorings. Many engineers will say that there is no need to redesign. It will corrode time like a black hole, delay release by a full month, and even waste human and financial resources.


At some stage of the development process, decisions made during the early design phase can cause deadlocks. Therefore, it's best to get the basics right before you start coding.


Software development is an iterative and improved process, but it doesn't have to be perfect from the beginning. But that is not a justification for suspicious building design.



3. Software architecture in software engineering

Software engineering software architecture helps expose the structure of a system while hiding implementation details. Architecture, like software engineering, focuses on relationships and how elements and components interact.


In fact, software architecture and software engineering often overlap. These are combined because many of the same rules govern both practices. When decision-making focuses on software engineering and software architecture follows, different things sometimes happen.


It is important to note that all software architectures are engineering, but not all engineering is software architectures. Software architects can distinguish between the details of software engineering and what is important to its internal structure.



4. Software architecture design tool

Software architecture design tools are used to build software architectures without major flaws or problems. With the right tools, you can reduce the possibility of bugs in your software implementation and design flaws that affect you late in development or when your software is used frequently.


Software architecture design tools help you build software that is free of security issues. This is important because there are software risks in all areas of the software development process. When your team avoids software flaws and bugs, you can move forward with confidence.


However, this is not always possible, so software architecture design tools also need the ability to find and fix flaws efficiently while creating software. With software architecture design tools that can identify flaws, you can analyze basic software design, assess potential attacks, identify potential threat elements, and identify existing security weaknesses and gaps.

Tools like CAST are cost-effective because they can identify and fix design flaws throughout the software architecture design process, including the best time to find and fix problems. Alternatively, the tool can perform an architectural risk analysis, threat modeling, etc., to help you find, modify and redesign your software architecture.


Organizations that do not have access to the right software architecture design tools can be surprised by problems that may arise later. It can be fatal in some cases. Software architecture has obstacles that may go unnoticed for some time, but eventually, they do occur. The question is how much risk and how much work was done before it was noticed. This can affect your bottom line and compromise your company's security and reputation.


To prevent application decline, delivery teams need to deploy a software intelligence platform. The CAST Structural Analysis Engine, the Application Intelligence Platform, explores how software components interact, create visual representations, and help developers or new team members understand, support, and provide insights to help continue development.


  • Interactive Exploration of end-user applications that graphically display and explore the structure of an application and its code interdependencies according to the information collected during code analysis and stored in the AIP Knowledge Base.
  • Change Simulation-An impact analysis feature that simulates the impact of changes on an object.
  • Automatic Documents-HTML reporting capabilities for creating technical documents
  • Highlight the database model to see compliance between the backend layer and the database layer.
  • Finds the component and places it in the current graphical view of the transaction.
  • View all details about the source code and application components.
  • Extract high-level software architectures that represent all the technologies, frameworks, and databases in your application.



5. Software architecture pattern

  • Client-server

The architecture that works is based on the request/response model. The client sends a request to the server to get the information, and the server returns the data.


All websites you visit, including blogs, Facebook, and Twitter, are built on a client-server architecture.


  • Peer-to-peer

A P2P network is a network that is treated as a node for each computer to communicate with each other without the need for a centralized server. Since there is no centralized server, the single point of failure problem is eliminated. All computers on the network have the same permissions. Each node acts as a seeder and a reacher at the same time, so the system will continue to run even if some computers (nodes) are idle.


  • Model-View-Controller (MVC)

MVC architecture is a software architecture pattern in which application logic is divided into three components based on their functionality. The component is called as follows:


  1. Model: Represents how data is stored in the database.
  2. View: Displays information to the user.
  3. Controller: The component acts as an interface between the model and the view.


The MVC architecture is used not only on desktops but also on the web and mobile software.


  • Microservices

In a microservices architecture, various functions are divided into separate modules, which are linked to form a large-scale service.


This special architecture makes it easier to maintain, develop, test, and deploy than a monolithic architecture.


  • Event-driven

Event-driven architectures are very popular in modern application development.


It can handle many simultaneous connections with minimal resource consumption. Modern applications require a completely asynchronous model for scaling.


  • Layer

This pattern is used to structure a program that can be decomposed into subgroups, each with a different level of abstraction. Each layer serves the higher-level layers.


Typical layers are:

  1. Presentation layer
  2. Application layer
  3. Business logic layer
  4. Data access layer


  • Hexagon

This architecture consists of three components:

  1. port
  2. adapter
  3. domain


The focus of this architecture is to make the various components of the application-independent, loosely coupled, and easy to test.


This pattern uses the domain as the core of business logic. The outer layers are ports and adapters. The port acts as an API and interface. All input must go through the interface.
