17. Cloud Definition
• Definition from NIST(National Institute of Standards and Technology)
▪ Cloud computing is a model for enabling convenient, on-demand
network access to a shared pool of configurable computing
resources (e.g., networks, servers, storage, applications, and
services) that can be rapidly provisioned and released with
minimal management effort or service provider interaction.
▪ This cloud model promotes availability and is composed of five
essential characteristics, three service models, and four
deployment models.

18. In Our Humble Opinion
• Cloud computing is a paradigm of computing, a new way of thinking about IT
industry but not any specific technology.
• Central ideas
• Utility Computing
• SOA - Service Oriented Architecture
• SLA - Service Level Agreement
• Properties and characteristics
• High scalability and elasticity
• High availability and reliability
• High manageability and interoperability
• High accessibility and portability
• High performance and optimization
• Enabling techniques
• Hardware virtualization
• Parallelized and distributed computing
• Web service

20. Scalability & Elasticity
• What is scalability ?
• A desirable property of a system, a network, or a process, which
indicates its ability to either handle growing amounts of work in
a graceful manner or to be readily enlarged.
• What is elasticity ?
• The ability to apply a quantifiable methodology that allows for
the basis of an adaptive introspection with in a real time
infrastructure.
• But how to achieve these properties ?
• Dynamic provisioning
• Multi-tenant design

21. Availability & Reliability
• What is availability ?
• The degree to which a system, subsystem, or equipment is in a
specified operable and committable state at the start of a
mission, when the mission is called for at an unknown time.
• Cloud system usually require high availability
• Ex. “Five Nines” system would statistically provide 99.999% availability
• What is reliability ?
• The ability of a system or component to perform its required
functions under stated conditions for a specified period of time.
• But how to achieve these properties ?
• Fault tolerance system
• Require system resilience
• Reliable system security

22. Fault Tolerance
• What is fault tolerant system ?
• Fault-tolerance is the property that enables a system to continue
operating properly in the event of the failure of some of its
components.
• If its operating quality decreases at all, the decrease is
proportional to the severity of the failure, as compared to a
naively-designed system in which even a small failure can cause
total breakdown.
• Four basic characteristics :
• No single point of failure
• Fault detection and isolation to the failing component
• Fault containment to prevent propagation of the failure
• Availability of reversion modes

23. Parallel Processing
• Parallel Processing
• Parallel processing is a form of computation in which many
calculations are carried out simultaneously, operating on
the principle that large problems can often be divided into
smaller ones, which are then solved concurrently.
• Parallelism in different levels :
• Bit level parallelism
• Instruction level parallelism
• Data level parallelism
• Task level parallelism

24. Benefits From Cloud
• Cloud computing brings many benefits :
• For the market and enterprises
• Reduce initial investment
• Reduce capital expenditure
• Improve industrial specialization
• Improve resource utilization
• For the end user and individuals
• Reduce local computing power
• Reduce local storage power
• Variety of thin client devices in daily life
