Software design is responsible for the code level design such as, what each module is doing, the classes scope, and the functions purposes, etc. Or do you need something like a microservice architecture where the different features/tasks are split into separate respective modules/codebases?Ĭhoosing an architecture will determine how you deal with performance, fault tolerance, scalability, and reliability. For example, do you need serverless architecture which splits the application into two components: BaaS ( backend-as-a-service) and FaaS (functions-as-a-service)? Software architecture is used to define the skeleton and the high-level components of a system, and how they will all work together. There is often confusion between software design and architecture so we’ll break this down. The difference between software architecture and software design Still, this can’t be an excuse for not doing our homework. Though software development is an iterative and evolutionary process, we don’t always get things perfect at the first go. So, before we even touch the code and get our hands dirty, we have to make the underlying architecture right. It also depends on what stage of the development process we hit an impasse due to the hasty decisions taken during the initial design phases. It has the potential to push your shipping date further down the calendar by months, if not longer.Īnd that’s not even bringing up the wastage of engineering and financial resources which is caused due to this. Many engineers will tell you that you don’t want to delve into re-designing stuff. The architecture is its base and has to be carefully thought out to avoid any major design changes & code refactoring at a later point in time. If we don’t get the base right, we have to start over there is no other way around.īuilding a web application is no different. Now whether it is constructing a building or making a pizza. The key element in successfully creating anything is getting the base right. So with that said, let’s move on to why software architecture is important. It’s the decisions you wish you could get right early in a project. One of my favorite definitions of software architecture came from Ralph Johnson, co-author of Design Patterns: Elements of Reusable Object-Oriented Software. Each decision can have a considerable impact on quality, maintainability, performance, etc.
