3. Cloud computing is a form of internet based
computing that provides shared computer processing
resources and data to computers and other devices on
demand.
*Introduction

4. *Public Cloud
* It allows accessibility of systems and services to Public.
*Eg: Amazon, IBM, Microsoft, Google, etc.,
*Private Cloud
*It allows accessibility of systems and services with in the
organization.
*Hybrid Cloud
*It is mixture of public and private cloud.
*Types of Cloud

5. *Advantages of Cloud
*Scalable
*Reliable
*Inexpensive
*Location
Independent

*Scalable
*Secure
*Flexible

6. *Agility
* High availability and reliability
* High Scalability
* Multi Sharing
* Device and Location Independence
*Maintenance
* Low Cost
* Services in pay-per-use mode
*Cloud Characteristics

7. *Cloud Computing Architecture
Cloud computing architecture comprise of many
cloud components, Which are loosely coupled.
PARTS:
* Front End
* Back End
Each of the end is connected through a network,
usually internet.

8. Client Infrastructure
Application
Management
Cloud Runtime
Service
Infrastructure
Storage
Security
Front End
Back End

9. *Front End Platform
The front end refers to the client part of cloud
computing system.
It consist of interfaces and applications that are
required to access the cloud computing platforms.
Eg: Web Browser.

10. *Back End Platform
The back end refers to the cloud itself.
It consist of all the resources required to provide
cloud computing services.
It comprise of huge data storage, virtual machines,
security mechanism, services, deployment models,
servers, etc.

11. * Clients
* Datacenter
* Distributed Server
*Cloud Components

12. *Clients
Clients are the device that the end user interact to
manage their information on cloud.

13. *Categories of Clients
Mobile:
Mobile device include (PDA SMARTPHONE
or IPHONE). Now these device are portable and work on
wireless access of network, through internet.
Thin Clients:
Thin computers are that do not have internal
hard drives, but rather let the server do all the work and
then display the information.
Thick Clients:
These are regular computer that do contain
internal hard disk and use web browser.

14. * Datacenter is collection of server where application to
which you subscribe is housed.
* It could be a large room in a basement, or room full of
server which you access through internet.
*Datacenter

15. *Distributed Clients
*Now the server don’t have to be housed in same
location often server are in dispersed geographically
location but to you the cloud subscriber, these server acts
if they are humming right away next to each other.

16. *Cloud Service Models
Infrastructure as a Service | IaaS
*Customer access the resources such as servers,
networking, processing, storage, virtual machines and
other resources on a pay-per-use model.
*IaaS also known as Hardware as a Service (HaaS)

17. *Cloud Service Models
Platform as a Service (PaaS)
It offers the runtime environment for applications.
It also offers development and deployment tools
required to develop applications.
It has a feature of point-and-click tools that enables
non developers to create web applications.
Eg: App Engine of google

18. *Cloud Service Models
Software as a Service | SaaS
*SaaS is a software distribution model in which
applications are hosted by a cloud service provider and
made available to customers over internet.
*SaaS is also known as "On-Demand Software".

19. *Virtualization
Virtualization is the creation of virtual version of
something such as a server, a desktop, a storage device,
an operating system or network resources.
It is a technique which allows to share a single
physical instance of a resource or an application among
multiple customers and organizations.
It does by assigning a logical name to a physical
storage and providing a pointer to that physical resource
when demanded.

20. Hardware
Dividing a part of hardware and sharing resources
through virtual machine.
Desktop:
Cloud computing and server virtualization.
Software:
Application sharing.
Data:
Database sharing.
Network:
creation of virtualized network addressing space
within or across network subnets. .
*Types of Virtualization

21. *Cloud Platforms in Industry

22. *Top Cloud Computing
Companies
*Amazon Web Services
*Microsoft Azure
*Google Cloud Platform
*Adobe
*VMware
*IBM Cloud
*Rackspace
*Red Hat
*Salesforce
*Oracle Cloud
*SAP
*Verizon Cloud
*Navisite
*Dropbox
*Egnyte

23. *Amazon Web Service(AWS)
AWS is the safest and protected platform of
cloud service which offers a wide set of infrastructure
services like database storage, computing power,
networking etc.
Using this AWS one can host the static websites.
By using such services, users are able to build
complicated applications that are trustworthy, scalable
and flexible.
AWS is popular for Iaas and primarily for its
compute service EC2.

24. *Elastic Compute Cloud (EC2)
https://aws.amazon.com/ec2/pricing/
It provides secure, resizable compute capacity in
the cloud. It is designed to make web-scale cloud
computing easier for developers.

25. *Tools to support EC2
*Amazon Simple Queue Service (S3).
*Amazon Simple Notification service.

26. *Other Amazon Web Services
*Amazon simple storage system.
*Amazon Elastic Block Store.
*Amazon Simple DB.
*Amazon Relational DB service.
*Amazon cloudfront

27. Google App Engine is PaaS.
It bring language runtimes, frameworks, and
third party libraries for users.
Ex: Java, PHP, Python.
*Google App Engine.

28. This service created by Microsoft for building,
testing, deploying, and managing applications and
services through a global network of Microsoft-
managed datacenters.
It provide Saas, PaaS and IaaS and supports
many different programming languages, tools and
frameworks, including both Microsoft-specific and
third-party software and systems.
*Microsoft Azure
