In today’s data-driven landscape, efficient database scaling is crucial to maintaining performance and cost-effectiveness. Uday Kumar Manne, an authority in database architecture, explores the strategic choices between horizontal and vertical scaling, offering insights into their benefits, limitations, and future implications. His analysis provides essential guidance for architects seeking optimal scaling approaches tailored to specific application needs.
Vertical Scaling: Enhancing Power on a Single Server Vertical scaling, or scale-up, focuses on improving the performance of a single database server by upgrading its resources—such as CPU, RAM, and storage. Traditional relational databases benefit from this approach, where boosting a server’s capacity directly improves query response times and throughput, particularly for CPU-bound and memory-intensive tasks.
However, vertical scaling has limitations. Hardware improvements eventually reach a point of diminishing returns, where further upgrades provide minimal benefits. Additionally, this approach relies on a single server, which can lead to a single point of failure, increasing the risks to reliability. Despite these downsides, vertical scaling remains advantageous for applications …
