CONCEPT AND DEFINITION
Cloud networking is a public or private cloud
platform that hosts an organization's
networks and resources. It hosts the network
and capabilities partially or completely and
makes them available on demand when an
internet connection is available. It refers to
the cloud infrastructure that is used to
support resource connectivity and is based on
cloud computing.
WHAT IS CLOUD
NETWORKING

5. NEED OF CLOUD NETWORKING
Cloud networking is becoming more and more popular among
businesses as a way to gain access to stronger resources and
greater connectivity.
Virtual cloud networking is unquestionably the better option
due to the continuous advancements in technology. It is safer,
more user-friendly, more resilient, and ultimately more
economical in terms of both resources and expenses.

8. HOW DOES CLOUD COMPUTING
WORK?
Cloud computing is a
software structure to
keep data on remote
servers and can be
accessed via the
internet, it is divided
into front-end and back-
end components for
easy understanding.
Using an internet browser
or cloud computing
software, the front end
allows a user to access
data stored in the cloud,
while the backend acts as
the primary component of
cloud computing and is
responsible for securely
storing data and
information.
The central server follows
a set of regulations also
known as protocols to
enable the operations
more flexible. It employs
middleware software to
provide seamless
connectivity between
cloud-connected
devices/computers.

Cloud computing service
providers typically keep
numerous copies of data
to prevent security issues,
data loss, data breaches,
and so on.

11. PHYSICAL LAYER
Foundation layer of the cloud infrastructure.
Specifies entities that operate at this layer : Compute systems, network devices and storage devices. Operating environment, protocol, tools
and processes.
Functions of physical layer : Executes requests generated by the virtualization and control layer.
11CLOUD COMPUTING LAYERS
VIRTUAL LAYER
Deployed on the physical layer.
Specifies entities that operate at this layer : Virtualization software, resource pools, virtual resources.
Functions of virtual layer : Abstracts physical resources and makes them appear as virtual resources (enables multitenant environment).
Executes the requests generated by control layer.
CONTROL LAYER
Deployed either on virtual layer or on physical layer
Specifies entities that operate at this layer : control software
Functions of control layer : Enables resource configuration, resource pool configuration and resource provisioning. Executes requests generated
by service layer. Exposes resources to and supports the service layer. Collaborates with the virtualization software and enables resource pooling
and creating virtual resources, dynamic allocation and optimizing utilization of resources.

12. SERVICE ORCHESTRATION LAYER
Specifies the entites that operate at this layer : Orchestration software.
Functions of orchestration layer : Provides workflows for executing automated tasks. Interacts with various entities to invoke provisionning
tasks.
12CLOUD COMPUTING LAYERS
SERVICE LAYER
Consumers interact and consume cloud resources via thos layer.
Specifies the entities that operate at this layer : Service catalog and self-service portal.
Functions of service layer : Store information about cloud services in service catalog and presents them to the consumers. Enables consumers
to access and manage cloud services via a self-service portal.

13. BUSINESS CONTINUITY
Specifies adoption of proactive and reactive measures to mitigate the impact of downtime.
Enables ensuring the availability of services in line with SLA.
Supports all the layers to provide uninterrupted services.
13CROSS-LAYER FUNCTION
SECURITY
Specifies the adoption of : Administrative mechanisms (security and personnel policies, standard procedures to direct safe execution of
operations) and technical mechanisms (firewall, intrusion detection and prevention systems, antivirus).
Deploys security mechanisms to meet GRC requirements.
Supports all the layers to provide secure services.
SERVICE MANAGEMENT
Specifies adoption of activities related to service portfolio management and service operation management.
Service portfolio management :
• Define the service roadmap, service features, and service levels, and establish budgeting and pricing
• Assess and prioritize where investments across the service portfolio are most needed
• Deal with consumers in supporting activities such as taking orders, processing bills, and collecting payments
Service operation management :
Enables infrastructure configuration and resource provisioning
Enables capacity and availability management and helps to monitoring cloud services and their constituent elements

14. CEN INSTANCES:
CEN instances are the basic resources that are used to create and manage cloud
networks.
CEN ARCHITECTURE CONSISTS OF FOLLOWING
COMPONENTS:

ARCHITECTURE OF CEN
BANDWIDTH PACKAGES
There is always a source of medium for communication. Bandwidth package is one
such medium which is required for a communication to take place.
NETWORK SERVICES
Network services such as domain name system (DNS) servers, content delivery
networks (CDNs), and intrusion detection systems (IDS) are also an important part.

15. CEN ARCHITECTURE CONSISTS OF FOLLOWING
COMPONENTS:
GATEWAYS:
15
ARCHITECTURE OF CEN
Gateways are used to connect virtual networks to the public internet or to other
networks.
FIREWALLS:
Firewalls are used to protect cloud resources from unauthorized access and to
prevent network attacks.
VIRTUAL NETWORKS
These networks are created using software-defined networking (SDN) technology,
which allows network administrators to configure virtual networks and network
resources from a central location.

16. COMPARING TRADITIONAL NETWORKING TO CLOUD
NETWORKING
TRADITIONAL NETWORKING
Limited Scalability.
High cost.
Relies on local backup and disaster recovery plans.
Limited Flexibility
Relies on physical hardware and on-premises servers.
CLOUD NETWORKING
Highly Scalable.
Lower Upfront cost.
Built-in disaster recovery and data redundancy.
Highly flexible, allows rapid deployment.
Relies on virtualized resources and remote servers

17. COMPARING CLOUD COMPUTING TO CLOUD
NETWORKING
CLOUD COMPUTING
Cloud computing is a general term for centralized
computing resources shared by many consumers.
It includes all of the cloud's services that are
required to keep applications functioning.
Includes servers, storage, databases, applications
Use cases: Hosting applications, data storage,
processing tasks
CLOUD NETWORKING
Cloud networking refers to the hosting of network
resources and capabilities in the public, private, or
hybrid cloud.
Cloud networking refers to the cloud infrastructure
that is used to support resource connectivity and is
based on cloud computing.
Includes virtualized network resources, routing,
security
Use cases: Facilitating connectivity, data transfer,
and security

18. INFRASTRUCTURE AS A
SERVICE (IAAS):
