CLOUD

Made by : Abhijeet Singh

 A way of computing, via the Internet.

 Shares computer resources instead of using software or
storage on a local PC.

 No need to install documents, software, Operating system.

 A physical storage center is no longer needed.

 A way to access Applications hosted on the web through
your web browser.

 Consist of Virtual Platform (OS) , Software and
infrastructures.

 Only need is High-Speed Internet.

 SaaS  Software-as-a-Service

 PaaS  Platform-as-a-Service

 IaaS Infrastructure-as-a-Service


 It's all On Demand
 Rich Internet application web sites
 Application as Web Sites
 Collaboration and email
 Office Productivity
 Client apps that connect to services in the cloud

• Eg: Flikr, Salesforce.com, Cisco WebEx office, Gmail, IBM

 Virtual Development-platform-as-a-service

 Database

 Message Queue

 App Servicer

 Reduce cost of buying & managing S/w & H/w

Example : Google App Engine, Microsoft SQL Server Data
Services, Engine Yard, Salesforce.com’s Force.com

 Backbone of Entire system

 Virtual servers

 Physical storage space

 Processing capabilities

 Logical disks

 VLAN networks

 Systems Management

Eg: Akamai, Amazon EC2, CohesiveFT, Mosso, Joyent Accelerators

1) Cost
 Greatly reduced Cost on purchasing diff kinds of Software , operating
system etc.
 No need to be purchased for one-time or infrequent computing tasks.
 Pricing of any services is compute on usage-based options
 Fewer IT skills are required for implementation (in-house)

2) Device
 Location independence enable to access systems using web browser
 Regardless of their location or device they are using (e.g PC, mobile).
 Accessed via the Internet, users can connect from anywhere.


3) Security
 Improve due to centralization of data
 More Focus on resources, etc.
 Security is greatly increased when data is distributed over a no.
of devices & Area.

4) Reliability
 Utilization and efficiency improvements for systems that are
often only 10–20% utilized.
 Suitable for Business continuity and disaster recovery.
 IT and business managers can at times do little when they are affected.

5) Maintenance
Applications are easier to maintain, since they don't have to be
installed on each user's computer.
Easier to support and to improve since the changes reach the
clients instantly.

( Online Operating System )

Note : Services is avail Free till its Developing Stage. Once completed become Chargeable.

1) Grid Computing
Collection of servers that are clustered together to attack a single problem.

 Form of distributed/ parallel computing is composed of a cluster of networked

loosely coupled computers acting in concert to perform very large tasks.

 If one piece of software on a node Fails, other pieces of s/w on other nodes may fail.

Example : Scientific Research

2) Cloud computing

A narrower form of client-server, between service providers (servers) and service
requesters (clients) where the details of the server are abstracted .

For example:- one may not connect to a specific server. However, due to the
popularity of the cloud metaphor, "cloud computing" may be used to refer to any form
of client-server computing.

1) Public cloud
 Public / External cloud describes cloud computing in the traditional
mainstream sense.
 Resources are dynamically provide on a self-service basis over the
Internet, via web applications/web services
 an off-site third-party provider who shares resources and bills.

2) Private cloud
 Private / Internal cloud are being used by some organization or group
of people on private networks.
 Deliver some benefits of cloud computing without the pitfalls
 Data security, corporate governance, and reliability concerns.
 Users have to buy, build, and manage them.
Example : PNB, HDFC, SBI Bank Cloud.

3) Community cloud
 Established by several organizations to have Similar Requirements
 To share Infrastructure of the cloud computing.
 Collaborate together to perform bigger tasks/ operations.
 More expensive
 Higher level of privacy, security or policy compliance.
Examples: Google's "Gov Cloud".

4) Hybrid cloud

 Environment consisting of multiple internal or external providers.

 Users may be able to ease the transition to Public services.


 Your data is not directly in your hands,
but in the hands of a third party.

 Total Dependence on the Internet Connection.

If your cloud Host disappears, where does
your information go?


Mobile Cloud Computing

 Network-as-a-Service

 Platform-as-a-Service
