Software Architecture Types
Software architecture types differ because software architecture differs. Software architecture helps to describe and reach the requirements and expectations of software on both the operation and technical levels. Designers choose from the software architecture types because they need to change and mold to fit into rapidly changing models and businesses that change their business models quickly.
Software architecture needs to be extendable and maintainable, and it makes sense that the same type or style won’t work for every business. While software architecture needs to focus on performance and reliability, it also needs to focus on the type that is necessary.
While using the wrong software architecture type isn’t always devastating, it can create more work of the lifespan of your software.
Software Architecture Styles
When people talk about software architecture, they sometimes divide it into software architecture styles. Many people have heard of something called “Microservices,” which are one of many software architecture styles.
Microservices is one of the most popular ones, and it is the one that has been used by some of the biggest companies. Still, there are other software architecture styles that are important to know about especially when determinizing which ones to use:
Serverless architecture is a software architecture style that depends on third-party services for the management of servers and the backend. Typically, this is used in more complex systems. Serverless architecture has two different categories: “Backend as a service (BaaS)” and “Functions as a Service (FaaS).”
With this type of software architecture, development teams save a lot of time in regard to taking care of bugs and eliminating problems in deployment and the regular tasks delegated to servers.
This software architecture type is based on events. In general, event-drive architecture decouples a system’s parts and defines them individually, ensuring that each part will be triggered properly. This is great for businesses and software that has to do two tasks that are similar but have distinct differences that need to be tracked as such. However, until the software is smart enough to differentiate these events, they need to trigger different things that lead to the same results.
As mentioned, microservices architecture is one of the most popular types of software architecture within the last few years. This type of architecture focuses on developing small, independent modular services where each piece solves a specific problem OR carries out a unique task.
Layered Software Architecture
The most common software architecture pattern for today’s developers is the layered software architecture pattern, sometimes called or known as the “n-tier architecture pattern.” This pattern is the go-to practice for many Java EE applications and, therefore, is probably the most well-known by trained software architects, software designers, and software developers. The layered software architecture pattern isn’t a large jump from conventional practices. In fact, it closely matches the traditional IT communication and organizational structures found in most companies for the last many years, making it a natural choice for most business application development efforts as they move forward or start to design new systems and software architecture.
Still, there are problems with layered software architecture and it can be difficult to spot them without the proper tools.
Software Architecture For Developers
The primary goal of software architecture for developers is to identify requirements that will impact all the structures of the application. When software architecture is designed properly, it reduces the business risks associated with technical solutions. It can also serve as a tool to set, gauge, and meet business and technical goals within a business.
Some of the software architecture goals for developers include:
- Expose the architecture of said system but also conceal its implementation details.
- Realize use-cases and scenarios.
- Address the requirements of many stakeholders.
- Reach both functional and quality requirements.
- Advance market position.
- Improve quality and functionality.
- Improve external confidence in the organization or system.
Not asking the right questions about your software architecture can lead to serious decay over time not to mention outages and performance issues, including:
- Stop critical single points of failure.
- SOA repositories are typically built on a wide range of technologies.
- Give your architects and developers practical guidance.
- Make service reuse a reality.
- Deploy a system that automates the enforcement of these guidelines.
To prevent application decay, delivery teams must put in place a software intelligence platform. CAST structural analysis engine, the Application Intelligence Platform, look at how software components interact then creates a visual representation to provides insight to developers or new team members that help them better understand, support, and continue to develop the application.
- Interactive exploration - An end-user application to graphically display and explore the structure of an application and its code interdependencies, according to the information gathered during code analysis and stored in the AIP Knowledgebase
- Change Simulation - Impact analysis capabilities to simulate the impact of a modification to an object
- Automated Documentation - HTML report feature to create technical documentation
- Highlight database model and ensure adherence between back-end and database layers
- Search any component and position it on a current graphical view, on a transaction
- View source code and all details about any application component
- Extract high-level software architectures showing all the technologies, frameworks, and databases in the application
