To determine how much space is needed for a photo storage service, several factors must be considered. These include the number of users, the average number of photos per user, the resolution of the photos, and the desired retention period for the photos. Assuming an average of 500 photos per user, with each photo being 5 MB in size, and a retention period of 5 years, we can calculate the storage needed as follows: 500 photos/user * 5 MB/photo = 2500 MB/user 2500 MB/user * 1 GB/1024 MB = 2.44 GB/user 2.44 GB/user * 1,000,000 users = 2,440,000 GB or 2.44 petabytes (PB) This estimate assumes that all photos are stored at a high resolution, such as 4K or higher, which requires more storage space. If a lower resolution is used, such as 1080p, the storage needs would be lower. It is important to note that this estimate does not include additional storage needs for backups, redundancy, or other operational requirements. Therefore, we should add a buffer to the estimated storage needs to ensure the service can handle unexpected usage spikes and maintain data reliability. Overall, the exact amount of storage needed for a photo storage service will depend on the specific requirements of the service, but this estimate provides a baseline for planning and budgeting purposes.
