The document discusses the architecture and lifecycle of cloud computing, detailing key concepts such as cloud technology, deployment models (private, public, hybrid), and various service models (SaaS, PaaS, IaaS). It also covers virtualization methodologies and types, emphasizing their roles in cloud systems, and highlights the complexities and interdependent components of cloud ecosystems. Additionally, it addresses concerns related to cloud computing, such as availability, security, and data integrity.

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 Governance and Operations 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.
