Mid-Term Exam
1) Tom and Jerry are two friends with 10 and 2 toys each. If more friends come to visit Jerry, he may have to buy more toys, while Tom is not using his toys. So, Children keep all their toys in one big box and use them. This common big box is cloud computing.
2) I believe that “Maintenance Costs will be lower with cloud computing”. While moving from a private network to a cloud based network, the initial setup costs will be high. The cost required for setting up IT can never be reduced. But once the setup is completed, the cloud based company will be responsible for providing computational capabilities along with infrastructure which will helps in maximum resource availability like backup, resource availability, etc. The company purchasing a cloud based service can …show more content…
Each of the OS will be able to access the hardware independent of the other.
The only drawback would be the unavailability of a UI to manage these OSs. 4)
a) Consensus is the process of getting all the systems in the network to agree on a single value and this value must be proposed by one of the systems in the network. Any algorithm that requires multiple systems to agree on one solution will have to resolve the problem of consensus. An increase in the number open source distributed processing and storage systems have led to an increase in the need for consensus algorithms. A consensus may not be achieved due to number of issues like:
• Faulty communication lines.
• Faulty systems in the network.
• Inconsistencies in System time shared in the network.
b) Paxos algorithm is a consensus algorithm. It helps to ensure that multiple systems in a cluster agree upon a single value for the log. Any system in the cluster can act as a Proposer: sends a request to all the other systems in the cluster, Leader: Updates the log based on the most widely accepted value or Acceptor: Accepts the highest value for the
