Questions
- The architecture of distributed OSs typically are some mix of peer-to-peer and hierarchies (e.g. master/slave) in the arrangement of servers. Give an example of each and explain why the choice was made (a hierarchy versus peer-to-peer).
- "UNIX compatibility is increasingly sacrificed in order to improve scalability." Argue for or against.
- Ceph is the solution to what problem? How does it solve that problem? (Choose at least one problem to discuss.)
- Describe three strategies used to increase scalability in distributed operating systems. Give and explain specific examples of each.
