4. Cloud Lifecycle Model
The Cloud Life Cycle (CDLC) is the repeated life cycle
model for growth deployment and delivery of cloud.
 Requirement and Analysis
 Architect
 Implementation and Integration
 Quality Assurance and Verification
 Deploy, Testing and Improvement
 Monitor, Migrate and Audit

7. Role of Cloud Modeling and
Architecture
Service Models
 Cloud Software as a Services
 Cloud Platform as a services
 Cloud Infrastructure as a Services
Deployment Model
 Private Cloud
 Community Cloud
 Public Cloud
 Hybrid Cloud

8. Cloud Computing Architecture
• Cloud Computing is an Internet-based
technique using shared resources available
remotely.
• Eg. Gmail and Yahoo
Cloud Computing Type
 Public Cloud
 Private Cloud
 Hybrid Cloud

9. Cloud Computing Reference Model
• Cloud Enablement Model
• Cloud Deployment Model

• Cloud Ecosystem Model
Cloud System Architecture
• Single Cloud Site Architecture
• Redundant 3-tier Architecture
• Multi-datacentre Architecture

10. Cloud Deployment Model
• Private Cloud
• Public Cloud
• Hybrid Cloud
• Community Cloud
• Combined Cloud
• Inter Cloud (Cloud of Clouds)

11. Cloud Ecosystem Model
• Cloud ecosystem is a term, which defines
the complexity of the system in terms of its
interdependent components that work
together to enable cloud services.

14. REASON FOR THE USAGE OF
LOW CLOUD COMPUTING
Cloud Availability
Cloud security
Erosion of data integrity
Data replication and consistency issues
Potential loss of privacy
Lack of auditing and logging visibility
Potential for regulatory violations.

15. Definition of Virtualization
• ‘Virtualization’ is a methodology for
dividing the computer resources to more
one execution environment by applying
more concepts like partitioning, time-
sharing, machine simulation and
emulation.

16. Types of Virtualization

17. Server Virtualization: It is a kind of virtualization ,
used for masking of server resources , which
includes number of physical servers , processors and
operating Systems.
Network Virtualization: It is a method where
network resources are combine based on available
bandwidth.
Storage Virtualization: In this Virtualization , where
a pool of physical storage from different network of
storage devices appear as single storage device

18. Desktop Virtualization:
It supports various computing such as utility and
dynamic , testing development and security.
Hardware Virtualization:
It is the abstraction of computing resources from
the software that uses cloud resources. It
involves embedding virtual software into server
hardware components

19. CLOUD VS VIRTUALIZATION

21. Virtualization In Grid
• The main focal point in grid computing
lies in secure resource sharing in
accessing computers, software and data in
a dynamic atmosphere, sharing of those
resources has to be fine-tuned and
handled in a highly controlled manner.

22. Virtualization In Cloud
• Virtualization is a tool for system
administrators, which has many technical
uses than a cloud. Virtualization allows
IT organization to perform multiple
operations using a single physical
hardware.

23. Virtual infrastructures
• The internet provides services such as
research, mining, e-mail and maps.
• Provides an environment where non-
trusted application can be run.
• Adopts isolation techniques.
• Allows dynamics deployment of
application.
• Applied optimization in os.
• Manages as a single services.
