The Invisible Artistry of Backend Development

Architecture is often celebrated as a fine art, particularly when a building's aesthetic features stand out. Yet, a beautiful design alone does not guarantee functionality.

Architectural design requires a blend of technical precision and artistic vision. The form of a building should directly serve its intended function, illustrating the principle that form should follow function. For example, the Royal Ontario Museum in Toronto, despite its striking appearance, has been criticized as one of the 'worst examples of architecture during the 2000s' due to its impractical interior spaces characterized by awkward corners and slanted walls that compromise usability.

Similarly, in software development, while users may admire a well-designed interface, they often overlook the backend architecture that equally influences their experience. Software architects face myriad design decisions that affect an application's performance, scalability, and future adaptability. Their challenge isn't just to create something elegant but to design systems that are both effective and maintainable.

This article highlights the often 'invisible' artistry of backend software engineers, acknowledging that creating performant, scalable, and maintainable software architectures is an art form in its own right.

We Don’t Look at Software as a Creative Art

Software development is often perceived more as a functional craft than a creative art, likely because of its roots in engineering. This background has historically aligned software development more with manufacturing principles — predictable, efficient, and repeatable processes — rather than the nuances of creative design.

During the rapid expansion of computer usage in the 1960s and 1970s, businesses and governments needed reliable software quickly, leading to methodologies that mirrored factory assembly lines. This approach emphasized division of labor, where individual programmers focused on specific tasks, thereby limiting the scope for creativity in favor of functionality and bug-free code.

However, this view neglects the inherent creativity and dynamism in software engineering.

Consider the differences between manufacturing cars and developing software. In car manufacturing, processes are standardized with fixed objectives and requirements, focusing solely on output. You don’t see new requirements introduced mid-assembly line, new machinery being swapped in for the old during production, or users testing very early versions of the car directly on the factory floor.

In contrast, software development is dynamic, with requirements, tools, and even end goals shifting significantly during the project lifecycle. What starts as a car might evolve into a pirate ship due to changing business needs, technological advancements, or user feedback.

Creativity is essential in software development, influencing all aspects from user interface design to system architecture and complex problem-solving. Recent recognition of the creative aspects in fields like game development, web design, and user experience has begun to balance the narrative, showcasing that artistic design is as crucial as technical proficiency in developing software.

We May Recognize a Beautiful UI Design, but What About a Great API Design?

A design-oriented approach, which is prevalent in software development, centers around a user-centric problem-solving process. This methodology encourages developers to empathize with users, define problems, ideate solutions, prototype, and test, all of which require creativity.

While the influence of this approach is readily apparent in user interfaces (UIs) due to their direct interaction with users and visible aesthetic elements, its application extends beyond the front end to other crucial elements like system architecture and API design.

For example, APIs (Application Programming Interfaces) play a transformative role in enhancing internet user experiences by streamlining access to services and simplifying complex tasks. A well-crafted API enables seamless interactions between different systems, facilitating a more integrated and smooth user experience across various applications and services.

Here are a couple of examples:

• Stripe API: Revolutionizing online payments, Stripe provides developers with a flexible, customizable, and straightforward API. It allows even small startups to implement sophisticated payment systems that are both robust and secure, significantly improving the e-commerce experience.
• OpenAI's GPT API: As one of the most popular APIs in recent years, it offers advanced natural language processing capabilities. Developers can integrate features such as chatbots, automated content generation, and more into their applications. This not only enhances user interactions but also creates more intuitive and human-like experiences in customer service and interactive applications.

How Backend Design Decisions Shape the User Experience

Backend design decisions critically shape the user experience, directly influencing the application loading time, how fast you can search the data, how seamless the user experience is in any given location, etc. In summary, these choices affect everything from the application's responsiveness to its stability across different environments.

Key areas impacted by backend decisions include:

• Tech stack selection: The choice of technology—programming languages, databases, and server architecture—affects how quickly and efficiently data is processed and delivered to the user.
• Architectural style and patterns: Opting for specific architectural styles (e.g, microservices or serverless) impacts scalability and the ability to update features without disrupting user interactions.
• Third-party integrations: The integration of legacy systems and third-party services can enhance functionality but requires careful handling to maintain performance and ensure data consistency.
• Data structure design: How data is organized and managed (especially in distributed systems) directly impacts how quickly data can be accessed and manipulated, affecting everything from search functionality to transaction processing.

These backend choices are often invisible to the end-user until an issue arises, and then they become glaringly apparent. Things like slow load times, downtime, or data inconsistency highlight how important robust system design is to ensure continuous user satisfaction.

How Backend Design Decisions Shape the Org

Backend design decisions extend beyond user interaction, fundamentally shaping an organization's ability to scale its product, grow its user base, and be innovative.

The system design of software is not only a cornerstone for technical robustness but also crucial for economic sustainability over time. When designed poorly, systems accumulate architectural technical debt, which is often costlier and more complex to resolve than code-level technical debt, and can lead to severe operational disruptions.

Indeed, the major outages experienced by industry giants like AT&T, Meta, and AWS over the past 18 months illustrate the dire consequences of unchecked system complexity.

Furthermore, backend flexibility plays a vital role in an organization's agility—its capacity to swiftly adapt to market changes and seize new opportunities.

A great example of this is the explosive user growth experienced by the Cara app, a platform built by volunteers to allow artists to share their portfolios.

Cara's backend, designed with serverless architecture, scaled remarkably to support a jump from 40,000 to 650,000 users in just one week. While this rapid scalability enabled Cara to capitalize on a market opportunity, it also led to a substantial, unexpected cost— a $98,000 Vercel bill after a few days of peak usage.

This underscores that each architectural decision carries its own set of trade-offs and necessitates a delicate balance between addressing immediate needs and anticipating future demands. It highlights the creative challenge of aligning current requirements with potential future scenarios in a dynamic market landscape.

Conclusion: The Unseen Artistry of Backend Engineers

In software development, the artistry behind backend architecture is often invisible yet immensely impactful.

As we continue to demystify the backend, it becomes clear that these engineers are not just coders; they are the modern-day architects of the digital world, crafting foundational structures that empower businesses and enhance user experiences.

Embracing this perspective can transform how organizations value and execute their software initiatives, ensuring that both the visible and hidden elements of our digital solutions are crafted with artistry and foresight.
