Problem
Answer the following questions:
I. Identify the milestones in the evolution of operating systems during the half century from 1960 to 2010 and comment on the statement: "Hypervisors give OS developers another opportunity to develop functionality no longer practical in today's complex and ossified operating systems, where innovation moves at a geologic pace."
II. Virtualization of the processor combined with virtual memory management pose multiple challenges; analyze the interaction of interrupt handling and paging.
III. Key issues for network design in [289] are: (i) algorithms to prevent lost packets from permanently disabling communications; (ii) host-to-host "pipelining" so that multiple packets could be en-route from source to destination, if intermediate networks allow it; (iii) end-end checksums, reassembly of packets from fragments, and detection of duplicates, if any; (iv) the need for global addressing; and (v) techniques for host-to-host flow control. Discuss how these issues were addressed by the TCP/IP network architecture.
IV. Analyze the challenges of transition to IPv6. What will be in your view the effect of this transition on cloud computing?
V. Analyze the advantages of memory-based checkpointing.
VI. Identify the main security threats for the SaaS cloud delivery model on a public cloud.
VII. Analyze Amazon privacy policies, and design a service level agreement you would sign if you were to process confidential data using AWS.
VIII. Compare the benefits and the potential problems due to virtualization on public, private, and hybrid clouds.
