4. What is Cloud Computing?
Distributed computing on internet Or delivery
of computing service over the internet.

6. • Concept evolved in 1950(IBM) called RJE
(Remote Job Entry Process).
• In 2006 Amazon provided First public
cloud AWS(Amazon Web Service).
• In 2008-2009 launches of Google app
engine/ windows.
History

7. Traditional Software Cloud computingVs

8. Cloud Components
It has three components
1.) Client computers
2.) Datacenters
3.) Distributed Servers

9. Clients are the device that the end user
interact with cloud.
Three types of clients:
1.) Mobile
2.) Thick
3.) Thin (Most Popular)
Clients

10. It is collection of
servers where
application is placed
and is accessed via
internet.
Datacenter

11. Distributed servers
Often servers are in geographically
different places, but server acts as if they
are working next to each other.

12. Cloud Service Models

13. SaaS(Software as a service): Required software,
Operating system & network is provided.
In the SaaS model, cloud providers install and operate
application software in the cloud and cloud users access the
software from cloud clients. Cloud users do not manage the
cloud infrastructure and platform where the application runs.
This eliminates the need to install and run the application on
the cloud user's own computers, which simplifies
maintenance and support.
Examples of SaaS include: Google Apps, Microsoft
Office 365, Onlive, GT Nexus, Marketo and TradeCard.

14. PaaS(Platform as service): Operating system and
network is provided.
In the PaaS model, cloud providers deliver a computing
platform typically including operating system, programming
language execution environment, database, and web server.
Application developers can develop and run their software
solutions on a cloud platform without the cost and complexity
of buying and managing the underlying hardware and software
layers.
Examples of PaaS include: AWS Elastic Beanstalk, Cloud
Foundry, Heroku, Force.com, EngineYard, Mendix,
OpenShift, Google App Engine, Windows Azure Cloud
Services and OrangeScape

15. IaaS(Infrastructure as aservice): just Network is
provided.
In the most basic cloud-service model, providers of IaaS offer
computers physical or (more often) virtual machines and other
resources. IaaS clouds often offer additional resources such as a
virtual-machine disk image library, raw (block) and file-based
storage, firewalls, load balancers, IP addresses, virtual local area
networks (VLANs), and software bundles.[49] IaaS-cloud providers
supply these resources on-demand from their large pools installed
in data centers.
Examples of IaaS providers include: Amazon EC2, Azure Services
Platform, DynDNS, Google Compute Engine, HP Cloud, iland,
Joyent, LeaseWeb, and Oracal

• Microsoft windows Azure
• Savvis
• Google App Engine
• Vmware cloud
• Rack space
• Go grid

17. Typesof Cloud

18. Public Cloud: The services are delivered to the
client via the Internet from a third party service
provider.
Example: Amazon

19. 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.
Example: HP Data Centers

20. Hybrid cloud: It is a combination of services provided by
the Private and public cloud
Example:
–ERP in private cloud
–Sales & Email in public

21. Advantages
1. Lower computer costs.
2. Improved performance.
3. Reduced software costs.
4. Instant software updates.
5. Unlimited storage capacity.
6. Increased data reliability.
7. Universal document access.
8. Latest version availability.
9. Device independence.

22. Disadvantages
1. Requires a constant Internet connection.
2. Does not work well with low-speed
connections.
3. Features might be limited.
4. Can be slow.
5. Stored data might not be secure.
6. Stored data can be lost.

23. Application
• Social Networking sites.
• E-mail sites.
• Search Engines.
• Many more services OVER THE
INTERNET.
