 What is Cloud Computing

Cloud computing is an umbrella term used to refer to Internet based development and services. 

Page 5: Cloud computing

   

Used in Online tools for email,productivity software, business applications, and data storage

Eliminates costs related to on-site installations of hardware, software, and IT support staff

Available from any location and device with an internet connection

Who are all in the Cloud?

Online email accounts (Gmail, Yahoo) Social networking sites (Facebook, Twitter) Photo sharing sites (Flickr, Picasa) Search engines (Google, Bing) Productivity software (Google Docs) Personal finance software (Quicken, online banking and bill paying tools)

Page 7: Cloud computing

   

CHARACTERISTICS: A number of characteristics define cloud data, applications services and infrastructure:

Remotely hosted: Services or data are hosted on remote infrastructure.

Ubiquitous: Services or data are available from anywhere.

Commodified: The result is a traditional utilities, like electricity - you pay for what you would want!

Page 8: Cloud computing

   

Economics:

 Cloud computing users avoid Capital                      Expenditure (CapEx) on hardware, software, and   services when they pay a provider only for what     they use.

  Shared infrastructure and costs, low                        management  overhead, and immediate access to    a broad range of applications.

   Layers:

(i) Client :

 A cloud client             consists of                 computer hardware    and/or computer software that is        specifically designed for delivery of cloud services

Page 10: Cloud computing

   

(ii) Application : Cloud application services or "Software          as a Service (SaaS)" deliver software as a     service over the Internet. 

 eliminating the need to install and run the       application on the customer's own                  computers and simplifying maintenance         and support.

Page 11: Cloud computing

   

(iii) Platform :

 Cloud platform services or "Platform as a      Service (PaaS)" deliver a computing              platform and/or solution stack as a              service.

 It facilitates deployment of applications        without the cost and complexity of buying   and managing the hardware and software   layers.

Page 12: Cloud computing

   

(iv) Cloud Infrastructure as Service:  "Infrastructure as a Service (IaaS)" delivers computer infrastructure, typically a platform virtualization environment as a service

Rather than purchasing servers, software,network equipment, clients instead buy those resources as a fully outsourced service

The service is typically billed on a utility computing basis and amount of resources consumed

Page 13: Cloud computing

   

(V) Server : 

The servers layer consists of computer                hardware and/or software  products  that are specifically designed for the                    delivery of cloud services

 It including multi­core processors, cloud­             specific operating systems and                            combined offerings

Deployment Models :

Page 15: Cloud computing

   

Public vs Private cloud :

Page 16: Cloud computing

   

 By integrating multiple cloud services users          may be able to ease the transition to public          cloud services while avoiding issues such as     PCI compliance.

 A hybrid cloud environment consisting of              multiple internal and/or external providers "will     be typical for most enterprises".

Hybrid Cloud :

Page 17: Cloud computing

   

Cloud storage :

 Cloud Storage is a model of  networked Computer data                  storage.

 Data is stored on multiple virtual servers, generally hosted by third parties, rather than being hosted on dedicated servers.

Page 18: Cloud computing

   

The Intercloud :

 The Intercloud is an interconnected global "cloud of clouds" and an extension of the Internet "network of networks" on which it is based.

Page 19: Cloud computing

   

Issues : 

(i) Security ­ data storage and transmission encryption, user authentication, and authorization (data access) practices.

­worry about the vulnerability of remote data to such criminals as hackers, thieves...etc

(ii)Reliability –  To avoid the loss of data using redundant storage techniques, but it is still possible that a service could crash.

Page 20: Cloud computing

   

(iii) Ownership – In  cloud, some people worry          that they could lose some or all      of their rights or be unable to protect the              rights of   their customers.

(iv) Data Backup – Cloud providers employ              redundant servers and routine data backup            processes. ­   some people worry about being able to                 control their own backups .

Page 21: Cloud computing

   

Data Portability and Conversion – Porting and converting data is highly dependent on the nature of the cloud provider’s data retrieval format.

Multiplatform Support – An issue for IT departments using managed services is how the cloud­based service integrates across different platforms and operating systems.

Page 22: Cloud computing

   

Intellectual Property ­  A company invents something new and it uses cloud services as part of the invention. Not secured in cloud.

Page 23: Cloud computing

   

Future of cloud Computing:

 Cloud computing is still in its infancy, and the future is still being defined.Made possible due to high-speed Internet.

No matter the country, anyone can compete in this market and define its the future.

Page 24: Cloud computing

   

 Technology will evolve from services into full-fledged operating systems.

Google, Microsoft, and Apple are three likely contenders in the future of the industry.
