2. Is there any computer in clouds ?
Why Cloud
??
• Structure similar to ‘Cloud’.
NO
Does performance get affected by rain ?

3. How ?
 No fix structure.
 Keep changing. Not stationary also.
 Creation and Dispersion both occur simultaneously.
• No fix structure.
• Keep changing.
• No. of users & network as part of tech.
• Sometimes may be present & sometimes may not be present.
• Creation and Dispersion both occur simultaneously.
That’s why named as “Cloud”.
Similarly In this technology also -

4. Applications - we use this technology in 2 ways:
 Cloud Storage
Storing data.
 Cloud Computing
Running Applications.
Sometimes only ‘Cloud’ is used for ‘Cloud Computing’.

5. Cloud Storage
 Is simply storing data & files And Performing
backups to an external location (offsite).
 This data is stored in a virtual server not in the
user’s actual device.
 Online file storage centre.
 Examples:
 Apple iCloud
 Dropbox
 Google Drive
 Amazon Cloud Drive
 Microsoft SkyDrive

6. Advantage
Easy to scale up & scale down.
 physically it’s not easy & also not economically favourable.
No worry to lose data
 Multiple backups are kept in different parts of the world.
Data Security
 It’s cloud provider’s responsibility to secure your data.

7. Cloud Computing
 Is running Applications through a virtual desktop over a secure internet
connection.
Examples
 Playing High End games
 You don’t need a high end computer , just need a good
internet connection.
 Online video editing
 Online photoshop
 Online file converter
 Running any application online
without having the whole application in your system.

8. Cloud Computing
 Provides on demand service.
 Use it when you need it.
 Shared Resources.
 Are used by multiple clients.
 Scalability
 Upscaling & down scaling is very easy.
In other words..
A model for managing, storing and processing data online via the internet.

9. Cloud Architecture
9
• 3 Delivery models
 SAAS
 PAAS
 IAAS
• Services are offered based
on these 3 delivery models.

10. Software as a Service (SaaS)
 Independent Platform
 Don’t need to install software on your PC(Generally).
 Accessible from Web browser or
lightweight client applications.
 Computing resources are managed by vendors.
 network, servers, operating systems, storage.. etc
 Available for multiple end users.
 End Customers uses SAAS regularly.
 Examples- Gmail , Google Doc, Google Drive, MS office 365 ..etc.

11. Software as a Service (SaaS)
Advantage
 Universally accessible from any platform.
 You can work from anywhere.
 Excellent for collaborative working.
Disadvantages
 Browser Issues.
 Internet performance may affect overall performance.

12. Platform as a Service (PaaS)
 Made up of a Programming language execution environment, An
operating system, A Web browser and A Database.
 These encapsulate the environment where users can build their
programs without worrying of underlying in infrastructure.
 Data & Applications are managed by users.
 All others resources are managed by the vendor.
 Developers are Regular users of PAAS.
 Examples- Google app engine, Windows Azure, Amazon Web Services
…etc.

13. Platform as a Service (PaaS)
Advantage
 Cost effective & Rapid Development.
 Faster market for Developers.
 Easy deployment of web applications.
 Private & public deployment is possible.
Disadvantages
 Developers are limited to the provider’s language & tools.
 Migration issues –Such as the risk of vendor lock-in.

14. Infrastructure as a Service (IaaS)
 offers the computing architecture, infrastructure, all computing resources
but in a virtual environment . So that multiple users can access them.
 Data storage, virtualization, servers & networking are managed by vendors.
 Users are responsible for handling other resources like Data, Runtime &
Middleware.
 Sys Admins Uses IAAS.
 Examples- Amazon EC2, Go Grid, Rackspace Cloud Servers... Etc.

15. Infrastructure as a Service (IaaS)
Advantage
 The Cloud provide the infrastructure.
 Enhanced scalability– Dynamic workloads are supported.
Disadvantages
 Security Issues.
 Network & Delays.

16. Future of Cloud Technology & It’s effect
 The software will be separated from the hardware.
 Clouds will make people richer.
 Data security field will grow with it.
 Many changes that we can’t imagine now…

17. Thank you
