Why is solution architecture important?

Solution architecture is the building block for an overall enterprise software solution that addresses specific problems and requirements. As the project size increases, the team becomes distributed globally. It is required to have a solution architecture in place for long-term sustainability and a solid foundation.

Solution architecture addresses various solution needs, keeping the business context intact. It specifies and documents technology platforms, application components, data requirements, resource requirements, and many important non-functional requirements such as scalability, reliability, performance, throughput, availability, security, and maintainability.

Solution architecture is vital for any industry and its solution. In the absence of solution architecture, there is a chance that software development could fail; projects can get delayed, get over budget, and not deliver enough functionalities. This scenario can be drastically improved by creating a solution architecture and applying experience and knowledge; all of which are provided by a solution architect. It helps to keep stakeholders from all areas – from non-technical business functions to technical development – on the same page, which avoids confusion, keeps the project on track within schedule and time, and helps to derive maximum return on investment(ROI).

Often, the solution architect requires customer collaboration in order to understand specifications. In a solution architect's role, the architect needs multiple skillsets from technical leaders and experts, to business analysts and project management. We will learn more about the solution architect's role in Chapter 2, Solution Architects in an Organization.

A good solution architecture puts specifications in place with a well-defined solution, which helps us to deliver and accomplish the final product, along with smooth product operability after launch. A single problem can have multiple solutions, and each solution has its constraints. Solution architecture considers all the solutions, and finds the best way, by creating a hands-on proof of concept that accommodates all of the business and technical limitations.
