The document provides an overview of cloud computing essentials from Alibaba Cloud. It defines cloud computing according to NIST as enabling on-demand access to a shared pool of configurable computing resources. The speaker then discusses key cloud properties like scalability, availability, and fault tolerance. The presentation also provides details on Alibaba Cloud's global infrastructure and popular products like Elastic Compute Service, Server Load Balancing, Auto Scaling, and Object Storage Service. It concludes with information on cloud certification opportunities from Alibaba Cloud.

- 6. 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. • 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.
- 7. 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
- 9. 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
- 10. 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
- 11. 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
- 12. 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
- 13. 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
