Many people hear about software architecture but don’t really know what it means or why it can be helpful. But when working on a software project, it is primordial to dedicate time to get a good software architecture, because if you think about, it’s the base of all the projects. So why is having a good software architecture so important?
When we talk about the architecture of a software, we talk about a plan that describes a set of aspects and decisions that are important to a software. This implies taking into consideration all kinds of requirements (performance, security, etc.), the organization of the system, how do the system parts communicate between each other, if there are some external dependencies, what are the guidelines and implementation technologies, what are the risks to take into consideration, and many more.
Going back to what I said, the architecture of a Software includes decisions. If you would make a change to one of the software’s aspects or decisions, would there be a huge impact and would it be very hard to change it?
Most probably, the answer will be yes. So why is it that we talk so much about having a good software architecture?
Here are the three main reasons why a good software architecture is so important when it comes to development.
In other words, the architecture will define the problems you might encounter when it comes to implementation. It also shows the organizational structure and makes it much easier to take decisions and manage all sort of change. It also permits us to get a better estimate of the time & costs of a project.
It’s very difficult to determine what a good software architecture is and there is no real right answer to this question. What we can say is that it makes products cheaper to develop and to maintain. In general, the facets of a good architecture are all interrelated and depend on each other. Like what?
Many people believe that only by looking at the final product, you can know that you have a good software architecture. That is definitely not true. But looking at the product, you can find “signs” of a good one. Again, this does not mean that if the following points are seen in the software, it automatically implies that you’ve got a great software architecture! Now that we made this clear, what are those indicators that could show your software has a good architecture?
Hopefully this article helped you understand the importance of a good Software architecture and why we are so obsessed with having a good one! It’s always important to think on the long term, building a software to make it functional right now can do the same but will it really support any sort of growth & change?
