CLOUD
Made by : Abhijeet Singh
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
Made by : Abhijeet Singh
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
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)
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.
1) Cost
2) Device
Made by : Abhijeet Singh
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.
3) Security
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.
5) Maintenance
Made by : Abhijeet Singh
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.

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.
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
1) Grid Computing
2) Cloud computing

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.
1) Public cloud
Made by : Abhijeet Singh
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.
2) Private 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".
3) Community cloud
Made by : Abhijeet Singh
Environment consisting of multiple internal or external providers. Users may be able to ease the transition to Public services.
4) Hybrid cloud
Your data is not directly in your hands,
but in the hands of a third party.
Made by : Abhijeet Singh
Total Dependence on the Internet Connection.
If your cloud Host disappears, where does
your information go?
