Capacity Planning in System Design

In our previous post, we discussed the fundamentals of System Design and introduced a 5-step framework. In this post, we will focus on the second step: Capacity Planning.

Capacity Planning is a critical aspect of System Design that involves doing these estimations -

1. User Growth
2. Traffic and Throughput
3. Storage and Data Growth
4. Compute and Memory Requirements
5. Network and Bandwidth
6. Latency and Concurrency

I have tried to break down these step by step here - Capacity Planning.

By the end of this post, you should have a solid understanding of how to perform each of these estimations and how they fit into the overall system design process.
