3. Trends in Computing
 Distributed Computing
 Cluster Computing
 Utility Computing
 Cloud Computing

4. Distributed Computing

5. Common properties of
Distributed Computing
 Each node play partial role • Each computer has only a limited,
incomplete view of the system. • Each computer may know only one part
of the input.
 Resource sharing • Each user can share the computing power and storage
resource in the system with other users – Load Sharing • Dispatching
several tasks to each nodes can help share loading to the whole system.
 Easy to expand • We expect to use few time when adding nodes. Hope to
spend no time if possible.
 Performance • Parallel computing can be considered a subset of
distributed computing

6. Cluster Computing
 A cluster is a type of parallel or
distributed computer system, which
consists of a collection of inter-
connected stand-alone computers
working together as a single
integrated computing resource .
 Key components of a cluster include
multiple standalone computers (PCs,
Workstations, or SMPs), operating
systems, high-performance interconnects,
middleware, parallel programming
environments, and applications

7. Utility Computing
 Utility Computing is purely a concept which cloud computing
practically implements.
 Utility computing is a service provisioning model in which a service
provider makes computing resources and infrastructure management
available to the customer as needed, and charges them for specific
usage rather than a flat rate.
 This model has the advantage of a low or no initial cost to acquire
computer resources; instead, computational resources are essentially
rented.

8. Introduction Cloud computing:
 With traditional desktop computing, we run copies of software programs
on our own computer. The documents we create are stored on our own pc.
 Although documents can be accessed from other computers on the
network, they can’t be accessed by computers outside the network. This is
PC-centric.
 With cloud computing, the software programs one use aren’t run from
one’s pc
 If a computer crashes, the software is still available for others to use. Same
goes for the documents one create; they’re stored on a collection of servers
accessed via the Internet.
 Anyone with permission can not only access the documents, but can also
edit and collaborate on those documents in real time.

9. History
1961 - The father of this idea is considered to be John McCarthy
- example sharing electricity
1999 - Salesforce.com
- delivering enterprise applications via a simple website.
2002 - Amazon Web Services
- provided a suite of cloud‐based services including
storage, computation and even human intelligence
2009 - Google
- services such as Google Apps

10. Cloud Architecture

11. Types of Cloud (Deployment Models)
 Public cloud.
 Private cloud.
 Hybrid cloud .

12. Public Cloud
 The Public Cloud allows systems and services to be easily accessible
to the general public. Public cloud may be less secure because of its
openness, e.g., e-mail
 Public cloud storage, or external storage clouds, enterprises and
small businesses offload their data storage and archival / backup
needs to a third-party cloud storage service provider, freeing them
from the expensive costs of having to purchase, manage and
maintain on-premises storage hardware and software resources

13. Private Cloud
 The Private Cloud allows systems and services to be accessible
within an organization. It offers increased security because of its
private nature
 A private cloud is designed to offer the same features and benefits
of public cloud systems, but removes a number of objections to the
cloud computing model including control over enterprise and
customer data, worries about security, and issues connected to
regulatory compliance

14. Hybrid Cloud
 The Hybrid Cloud is mixture of public and private cloud. However, the
critical activities are performed using private cloud while the non-
critical activities are performed using public cloud
 Hybrid cloud storage combines the advantages of scalability, reliability,
rapid deployment and potential cost savings of public cloud storage
with the security and full control of private cloud storage.

16. Some Cloud Service Providers

17. How to Create Cloud Storage
 Create an Account User
name and password.
 Content lives with the
account in the cloud.
 Log onto any computer
with Wi-Fi to find your
content

18. How to Download Storage
 Download a cloud based app to on your computer
 The app lives on your Computer
 Save files to the app
 When connected to the Internet it will sync with the cloud
 The Cloud can be accessed from any Internet connection

19. Real Life Example
EX: DROPBOX, GMAIL, FACEBOOK
The number of cloud storage providers online seems to grow every day.
Each competing over the amount of storage they can provide to clients.
Google’s email service provider Gmail, on the other hand, provides
unlimited storage on the cloud. Gmail has revolutionized the way we send
emails and largely responsible for the increased usage of email worldwide.
Facebook is a mix of the two, in that it can store an infinite amount of
information, images, and videos on your profile. They can then be easily
accessed on multiple devices. Facebook goes a step further with their
Messenger app, which allows for profiles to exchange data.

20. Example ….
 Right now, Dropbox is the clear leader in streamlined cloud storage
allowing users to access files on any device through its application or
website with up to 1 terabyte of free storage.
 Facebook is a mix of the two, in that it can store an infinite amount of
information, images, and videos on your profile. They can then be
easily accessed on multiple devices. Facebook goes a step further with
their Messenger app, which allows for profiles to exchange data

21. Architecture of Gmail:

22. Advantages of Cloud Computing
 Lower computer costs.
 Improved performance.
 Reduced software costs.
 Instant software updates.
 Improved document format compatibility.
 Unlimited storage capacity.
 Increased data reliability.
 Universal document access.
 Latest version availability.
 Device independence

23. Disadvantages of Cloud
Computing
 Requires a constant Internet connection.
 Does not work well with low-speed connections.
 Features might be limited.
 Stored data might not be secure.
 Stored data can be lost.

24. Conclusion
 Thus cloud computing provide a super-computing power .
 This cloud of computers extends beyond a single company or
enterprise.
 The applications and data served by the cloud are available to
broad group of users, cross-enterprise and crossplatform.
