How to design a system for scale

Scalability is essential for software engineers as applications grow. Three key techniques for scaling systems are adding server clones, functional partitioning, and data partitioning. Adding server clones involves creating interchangeable copies of existing servers to distribute loads. Functional partitioning breaks down the system into smaller, independent components each handling specific tasks. Data partitioning divides datasets across multiple machines to speed up processing and storage. Each technique has its pros and cons and requires careful consideration for effective implementation.
