Here's an outline of the approach I would adopt for each of the mentioned areas:
- Assessment: Understand the current system architecture, identify pain points, and forecast growth projections.
- Scalability Plan: Develop a roadmap outlining short-term and long-term scalability goals.
- Technology Stack Evaluation: Assess existing technologies and evaluate alternatives that can better support scalability requirements.
- Architecture Refactoring: Implement changes to the architecture to introduce scalability patterns like microservices, horizontal scaling, caching strategies, etc.
- Monitoring and Optimization: Implement robust monitoring tools to track system performance and continuously optimize for scalability.
