Presentation Description

oud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams. A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.

What is Cloud and Cloud Computing?: 

What is Cloud and Cloud C omputing? It is the 5 th Generation Computing Cloud computing is Internet -based computing , whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid . Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services.

Objective : 

Core objectives and principles that cloud computing must meet to be successful: Security, Scalability, Availability, Performance, Cost-effective, Acquire resources on demand, Release resources when no longer needed, Pay for what you use, Leverage others’ core competencies, Turn fixed cost into variable cost. Objective

Levels of Cloud’s Service

Slide 7: 

Software as a Service. No hardware or software to manage. Service delivered through a browser. Customers use the service on demand. Instant Scalability. SaaS

PaaS: 

Platform as a Service Platforms are built upon Infrastructure, which is expensive. Estimating demand is not a science! Platform management is not fun! P aaS

IaaS: 

Infrastructure as a Service A platform virtualization environment. Computing resources, such as storing and processing capacity. Virtualization taken a step further. I aaS

5 Essence of cloud: 

On-demand self-service. Broad network access(Internet). Resource Pooling - Location Independence. Rapid Elasticity. Measured Service. 5 Essence of cloud

Additional Cloud Characteristics: 

Massive and Rapid scalability, Homogeneity, Virtualization, Resilient computing, Low cost software, Geographic distribution (many datacenters), Service orientation, Advanced security technologies. Additional Cloud Characteristics

Types of Cloud Computing models: 

There are four types of Cloud Computing deployment models: Public Cloud, Community Cloud, Private Cloud, Hybrid Cloud. Types of Cloud Computing models

Advantages: 

Customer’s perspective: In one word: economics. Faster, simpler, cheaper to use cloud apps. No upfront capital required for servers and storage. No ongoing operational expenses for running datacenter. Applications can be accessed from anywhere, anytime. Advantages

Advantages: 

Vendor’s Perspective : Easier for application vendors to reach new customers. Lowest cost way of delivering and supporting applications. Ability to use commodity server and storage hardware. Ability to drive down data center operational costs. In one word: economics. Advantages

Disadvantages:: 

Customer’s perspective Data Security: - Many customers don’t wish to trust their data to “the cloud”. - Data must be locally retained for regulatory reasons. Latency: - The cloud can be many milliseconds away. - Not suitable for real-time applications. Application Availability: - Cannot switch from existing legacy applications. - Equivalent cloud applications do not exist. Disadvantages:

Disadvantages:: 

Vendor’s Perspective Service Level Agreements: - What if something goes wrong? - What is the true cost of providing SLAs? Business Models: - SaaS / PaaS models are challenging. - Much lower upfront revenue. Customer Lock-in: - Customers want open/standard APIs. - Need to continuously add value. Disadvantages:

Conclusion: 

Cloud Computing is the fastest growing part of IT. Tremendous benefits to customers of all sizes. Cloud services are simpler to acquire and scale up or down. Key opportunity for application and infrastructure vendors. Public clouds work great for some but not all applications. Private clouds offer many benefits for internal applications. Public and private clouds can be used in combination Economic environment is accelerating adoption of cloud solutions. Conclusion
