Components for migrating VMs and physical servers to Compute Engine. Remote work solutions for desktops and applications (VDI & DaaS). One optimization that can be done is to combine multiple photos in a single file and maintain an in-memory HashMap of photo_id to (location, offset). Cloud Storage utilisation - As we are sending modified chunks only to the server in case of update instead of the entire file again, it will decrease the cloud storage consumption. From database scalability point of view, database partitioning comes into picture to ensure scalability. But there are steps we can take collectively to make technology work better for everyone.
