Software architecture is crucial for several reasons, and its importance stems from its role in guiding the design, development, and maintenance of software systems. Here are some key reasons why software architecture is important:
System organization and structure: Software architecture defines the overall structure and organization of a software system. It provides a blueprint that outlines how different components and modules will interact, communicate, and work together to achieve the desired functionality. Without a well-defined architecture, the software might become chaotic and difficult to manage.
Scalability: A well-designed software architecture enables the system to scale efficiently. It allows for the addition of new features, modules, or users without requiring a complete overhaul of the entire system. This adaptability is crucial as software needs to grow and evolve to meet changing requirements and user demands.
Maintainability and Modifiability: A clear and well-documented software architecture makes it easier to maintain and modify the system over time. When the structure is well-organized and understood, developers can more effectively identify issues, fix bugs, and make enhancements without causing unintended side effects.
Reusability: Software architecture promotes the creation of reusable components and modules. When certain parts of the architecture are designed to be modular and independent, they can be used in multiple projects, reducing development time and costs while increasing overall consistency and reliability.
Collaboration and Communication: A shared software architecture serves as a common language for developers, stakeholders, and team members. It facilitates communication among different teams, ensuring that everyone has a clear understanding of the system's design, functionality, and constraints.
Risk Reduction: An established architecture helps identify potential risks and challenges early in the development process. By addressing architectural concerns proactively, the development team can reduce the likelihood of costly and time-consuming issues arising later in the project.
Performance and Efficiency: Software architecture plays a role in determining how efficiently a system operates. A well-optimized architecture can lead to improved performance and resource utilization, making the software more responsive and resource-friendly.
Security and Reliability: Security is a critical aspect of any software system. A well-thought-out architecture can incorporate security best practices, reducing vulnerabilities and improving the overall reliability and robustness of the software.
Decision Making: Software architecture guides various design decisions, such as technology selection, platform choices, and integration strategies. It helps stakeholders make informed decisions based on a systematic understanding of the software's structure and requirements.
Long-term Vision: Software architecture embodies the long-term vision of the software product. It ensures that the system's design aligns with the business goals and strategic objectives, providing a roadmap for future enhancements and expansions.
In summary, software architecture is essential because it provides a solid foundation for building complex software systems. It enables efficient development, facilitates collaboration, and ensures that the final product meets the desired functional and non-functional requirements while being adaptable to future changes.
One of the important aspect of SystemArchitecture is that this also does a lot of cost improvements for you. Since every use case does not require a huge system comprising of many machines and many people do not want to pay upfront for the services they have not used or are not going to use solutions proposed are different.
For example , lets say you are going to build a Notes application , this application lets your users keep a note of anything and many more features.
Now you have built the app, but you only have a few number of users testing it and you know it will take some time, lets say at-least an year for you to get to the user base of 10,000 + . That is still a small number to begin with but a good number.
Now, you do not need to invest huge in your application stack and application development since you are going to have a lot of learning along the way and change is constant .
You could go either ways, have the complete setup ready and event if you pay on the go for the services you use, it depends on the type of service you are using. Lets see that in the following pictures.
Solution 1: Fixed Cost (Pay as you go, billed for the hours your backend was running )
Solution 2: Use Cost ( Pay as you use the system)
Yes you read the titles right, while both the apps in production would have a backend and a database, in
Solution 1, you are going to pay in full for the running backend even if you did not have any traffic.
Solution 2 , you are only going to pay for the time your backend is consumed.
If you sit and do the math , you will find lambda was 10 times cost effective during the same phase and even more during you were scaling up. Once you have a customer base and you know you are going to have a million hits always , you can still sit again and refactor the architecture.
Serverless might still win .
