101 Guide For Software Architecture & How To Choose The Right One?

5 min read Jun 25, 2020

The evolution of recent technologies has directed us to the virtual sphere of software operating hand-in-hand with real lives. Software isn't confined only to carrying out complex business operations, but can even be seen assisting us in our routine life.

However, have you ever given a thought to what all it takes to develop software? How does software operate? Well, there are plenty of operations going on in the backend of software that is left unnoticed by us.

Developing a software accompanies numerous stages and demands a strong foundation in order to turn out as a product-market fit.

In this post, we are going to understand the nitty-gritty of software architecture and its patterns that lead businesses to make wise decisions and deliver remarkable user experiences.

Understanding Software Architecture

The software architecture of a system illustrates the system's structure and describes how it behaves. The software architecture offers a robust foundation over which the software is built. The software system architecture is a blend of technical decisions and scalable architecture patterns.

A wide segment of architecture decisions improve the performance, quality, maintainability, and, ultimately the success of the software. So, ignoring the software architecture role is just inevitable in today's digital age as it might put your system at risk and throw you out of the industrial race.

Significance of Software Architecture in 2020

The seamless software architecture can assist businesses in maintaining the internal quality that uplifts the software in the long run. No matter if the software is released late in the market, if it has an organized code, customers will simply love the software, unlike in the case of software that was launched earlier but had messy code. And since the competition is very stiff in today's time, you simply can't compromise on quality and risk your potential customers by delivering a messy and complex software.

While businesses plan to invest in a software architect, they can expect scalable solutions in the result while the software architect makes wise architectural decisions, conceptualizes and analyzes the architecture, keeps an eye on the recent software development trends, and meeting not only the present expectations but of the future as well.

While the software architecture is designed, prominent factors are considered that impact the deployment, development, and the entire maintenance cycle. Emphasizing on all these factors assists in avoiding schedule and budget outruns.

Prior to developing a software, the software architecture comprehensively scrutinizes the behavior of the software system. This analysis helps the developers to inform the stakeholders regarding the output expectancy while mitigating the probable risks. Thereby, you can even save a lot of costs that otherwise would be spent on making changes and fixing issues.

The software architecture will identify the reusable elements which can be utilized to develop the solution. The reusable components will enhance the software development lifecycle and can be seamlessly utilized across numerous systems whose stakeholders are looking for similar attributes.

Characteristics of an Ideal Software Architecture

An ideal software architecture holds the following characteristics that are accountable for developing perfect and flawless software:

• An ideal software architecture representing the structural details of the system.
• Picking up the core set of elements needed to develop the core functionality of the system.
• Capturing the early design decisions.
• Managing the stakeholder requirements and balancing the requirements thoroughly.
• Having a direct impact on the organizational structure.
• Conforms to a definite range of styles that have a lot of success in practice.

Understanding Software Architecture Patterns

We all have heard of design patterns that provide solutions to the probable problems. Well, the same patterns exist at a broader level too- patterns of software architecture. Software architecture patterns are the overall layout of the software and have their own set of benefits. So, let's explore the common software architecture patterns.

Layered Architecture

Layered architecture is the commonly used pattern as it is developed around the database and is similar to a self-fulfilling prophecy. The popular software frameworks, including Drupal, Java EE, and Express, are built over the layered architecture. The major benefit of a layered architecture is the separation of concerns that makes it easy to maintain, test, assign separate roles, and easy to update and uplift the layers independently.

The layered architecture is best suited for new apps that need to be built rapidly, business apps that reflect traditional IT processes, apps that need strict testability and maintainability standards, and for the newbies who don't have knowledge of any other architecture.

Event-driven Architecture

In the scenario where data needs processing and event-driven architecture can help in managing it by creating a central unit that accepts all data and further gives it to the separate modules. The event-driven architecture is easily scalable, easily adapt to complex environments, and is easily extendable in case new event types appear.

The event-driven architecture is best suited for user interfaces, asynchronous systems with asynchronous data flow, and apps where individual data blocks only interact with limited modules.

Microkernel Architecture

Various apps have wide operations that are used repeatedly in different patterns based on the data and task at hand. In that scenario, the basic routines to display and edit a file are a part of the microkernel. The microkernel architecture is best suited for apps with a clear division amongst basic routines and higher-order rules.

Microservices Architecture

The microservices architecture emphasizes assisting developers and creating multiple tiny programs and keep on doing that whenever someone request to add a new feature. It is quite similar to microkernel and event-driven architecture but is utilized when different tasks are easily separated.

Microservices architecture is best suited for websites with small components, swiftly growing new businesses and web apps, corporate data centers with well-defined boundaries, and development teams that are expanded globally.

Space-based Architecture

There are many websites that are built around a database and operate well until the database is able to cope up with the load. As the usage peaks, the database fails to manage the load during peak time. This is where space-based architecture comes in. The space-based architecture is built to get rid of functional collapse during high load by splitting processing and storage amongst multiple servers. So, it helps the businesses during unpredictable spikes and keeps them on the safer side.

The space-based architecture is best suited for high-volume data, including user logs and click streams, social networks, and low-value data that gets lost sometimes without major consequences.

After going through all the above software architecture patterns, businesses can get a clear idea of which pattern suits the best to them from which they can expect profitable results and business success. So, you need to invest a good time while analyzing your business strategy and then figure out that which of the above pattern suits your business perfectly.

A Win-Win Situation!

Picking the suitable software architecture for a business app is a decisive task which decides the utmost success of your business in the long run. The right software architecture will define the model of the software, it's functioning, and outlining the issues that might occur during the implementation process.

As software architecture progresses with time, we can expect a lot out of it and experience robust workflows in the years ahead. It will ensure consistent and superior quality throughout the software lifetime while making management effortless and accurate enough. Developers can save a lot of time and effort and impress the end customers in the long run, so it eventually turns out as a win-win idea.
