Building Scalable Web Applications with Modern Frameworks

Building scalable web applications requires careful planning, the right technology choices, and adherence to proven architectural patterns. This comprehensive guide explores the essential considerations and best practices for creating web applications that can grow with your business needs.

Understanding Scalability

Scalability refers to a system's ability to handle increased load without compromising performance. There are two main types of scalability:

Vertical Scaling (Scaling Up)

Adding more power to existing machines - more CPU, RAM, or storage. While simpler to implement, vertical scaling has physical limits and can be costly.

Horizontal Scaling (Scaling Out)

Adding more machines to the pool of resources. This approach offers better fault tolerance and cost-effectiveness but requires applications to be designed with distribution in mind.
