Large scale storage architecture is mostly 2 tier client server (Direct access = faster access). Three tier distributed system architecture consists of a server, middleware and multiple clients. As storage can […]
The challenges of Object storage with Ceph is that it needs to deal with huge files and directories, coordinate the activity of thousands of disks, provide parallel access to metadata on a massive scale, handle both scientific and general-purpose workloads, authenticate and encrypt at large scale, and
