Embracing the 3-Month Rule: A Practical Approach to Unscalable Solutions in Tech Development
In the ever-evolving landscape of technology, one piece of advice stands out: “Do things that don’t scale,” as famously articulated by Paul Graham. However, the challenge most developers face is translating this philosophy into actionable coding practices.
Having dedicated the past eight months to the development of my AI podcast platform, I’ve stumbled upon a guiding principle that I have dubbed the 3-Month Rule. The essence of my approach is simple: each unscalable solution is given a lifespan of three months. After this period, I evaluate whether it has shown its worth, warranting a robust framework, or whether it is time to phase it out.
Traditionally, as engineers, we are conditioned to design scalable solutions from day one, utilizing various sophisticated architectures that can handle vast user traffic. However, this is a mindset more suited to established corporations than to startups. In reality, premature optimization often leads to unnecessary complexity and inefficiencies. My 3-Month Rule compels me to embrace straightforward, albeit imperfect, code that can be deployed quickly, allowing me to best understand real user needs.
Current Infrastructure Strategies: Smart Choices for Rapid Learning
1. Unified Virtual Machine Deployment
All components, including the database, web server, and background processing, are hosted on a single virtual machine costing $40 a month. This setup lacks redundancy and requires manual backups.
Why does this configuration make sense? It provides invaluable insights into my system’s resource requirements. In just two months, I’ve gleaned that my resource demands peak at 4GB of RAM. Had I proceeded with complex Kubernetes setups, I would have been maintaining unnecessary infrastructure.
Moreover, when system failures occur (and they have twice), I gain empirical data on the origin of the disruption—often unexpected.
2. Simplified Hardcoded Configurations
Configuration parameters such as pricing tiers and user limits are hardcoded directly into the application rather than managed through configuration files or environment variables.
This seemingly outdated method holds an unexpected advantage. It allows for rapid searches of configuration values throughout the codebase. Each price or threshold change is easily tracked in version history, with minimal effort required to implement changes. In fact, the time spent redeploying for adjustments averages only 15 minutes, compared to the potential investment of many engineering hours for a configuration management service.
