TRANSCRIPT
What is Cloud Computing?
• The national survey was conducted in August 2012 by Wakefield Research
• Survey question – ‘What is Cloud Computing?’ was asked to 1,000 American adults.
• Survey result showed that 51% of the Americans are confused by the term “cloud”.
What is Cloud Computing Cont’d
• It is a Internet-based computing with shared resources, software, and information are provided to computers and other devices on demand.
‘Cloud’
• “Cloud” is simply a metaphor for the Internet.
• People don’t care what is in the ‘cloud’ but they depend on reliably sending data (rain) to and receiving data from it.
Key Characteristics
• Data stored on the cloud (Internet)
• Software and services available on the cloud
• Broad network access.
Cloud Computing Models
• Cloud Software as a Service (SaaS): The vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. Services can be anything from Web-based email to inventory control and database processing.– Example: Google Docs, Gmail, etc
Cloud Computing Models
• Cloud Platform as a Service (PaaS): A set of software and product development tools hosted on the provider’s infrastructure. Developers create applications on the provider’s platform over the Internet.– Example: Windows Azure
Cloud Computing Models
• Cloud Infrastructure as Service(IaaS): Delivers computer infrastructure as a service. Rather than purchasing servers, software, data center space or network equipment.
Cloud Computing Models
• Cloud Hardware as a Service(HaaS): • Hardware as a Service (Haas), in a grid-
computing context, is a pay-as-you-go model for accessing a provider's infrastructure and CPU power.
• Example: Amazon’s Elastic Compute Cloud
4 Types of Clouds
• Public Cloud: The services are delivered to the client via the Internet from a third party service provider.
4 Types of Clouds
• Private Cloud: These services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud.
4 Types of Clouds
– Organization having similar requirement. – Concerns related to privacy, security and
policy compliance
• Client: A cloud client consists of computer hardware and computer software which relies on the cloud for application delivery.
• Application: Runs over Internet, no need to install and maintain, complete customizable applications
• Platform: A cloud platform such as platform as a service, the delivery of a computing platform and for solution stack as a service, facilitates deployment of application.
• Infrastructure: Network of servers, Cloud infrastructure such as infrastructure as a service is the delivery of computer infrastructure typically a platform virtualization environment as a service.
• Server: Consists of computer hardware and software products that are specifically designed for the delivery of cloud services.
Microsoft
• Azure:– Internet-scale cloud computing and
services platform hosted in Microsoft data Centers.
– Provides a range of functionality to build applications that span from consumer web to enterprise scenarios.
The Future of Cloud Computing
• For now, companies don’t fully trust Cloud Computing and only uses it for small projects.
• Details such as licensing, privacy, security, compliance and network monitoring need to be finalized for the trust to be realized.
• A single hard drive for the rest of a person’s life, accessible anywhere with internet.
