📈 Rethinking Scalability: Beyond Transactions Per Second

In the realm of building scalable systems and architectures, a common focus is often on increasing transactions per second. However, this narrow perspective can occasionally lead us into a corner, especially when other dimensions of scalability demand attention.

Consider this: scalability isn’t just about handling more transactions. It encompasses a range of dimensions which are likely to change over time, such as:

• Expansion and innovation in features
• Growing customer base and their diverse needs
• Team members’ capabilities and growth
• The evolution of services, modules, or other technical components
• Managing increasing complexity
• Navigating additional dependencies and third-party libraries
• Adhering to increasing regulatory requirements
• Business-specific expansions, like additional warehouses or fleet for transportation businesses

Each factor requires us to think differently about our system designs. Understanding the likely directions of change enables us to make more informed, strategic trade-offs.

The challenge is that sometimes, we can’t predict which areas will change. Or, we know that any area we focus on now will evolve in the future.

👉 In such scenarios, it’s even more crucial to explore the solution space thoroughly, avoiding expensive or irreversible changes.

Decisions we make today should not unnecessarily or unreasonably restrict our options tomorrow.
