What factors would you consider when estimating the capacity needs for a cloud-based service as usage scales over time?

During my final year project, I was part of a team developing a web application for student collaboration. We anticipated varying user loads based on project milestones. To estimate capacity needs, we conducted surveys to gauge potential user interest, analyzed similar applications, and created usage scenarios. By estimating peak usage during exam periods, we ensured our application could handle simultaneous logins without crashing. This experience taught me the importance of user feedback and data analysis in capacity planning.

As a volunteer for a local charity event, I was tasked with managing online registrations. We expected a surge in sign-ups as the event date approached, so I estimated our server capacity based on previous events and the marketing strategy we employed. By anticipating high traffic days, we upgraded our hosting plan temporarily to ensure smooth registration. This experience highlighted the need for flexibility in capacity planning and the value of reviewing past data to inform future decisions.

During my internship at an e-commerce startup, I assisted in estimating capacity needs for our website. We analyzed traffic trends during sales events and identified peak times based on historical data. I collaborated with the technical team to develop a scaling strategy, including using cloud services that automatically adjusted resources based on traffic. This taught me about the importance of real-time monitoring and the ability to pivot quickly to meet user demand while ensuring a seamless shopping experience.
