Understanding the Basics of Cloud Networking

Cloud networking is a model where networking functions and services are hosted in the cloud rather than on-premises.

This approach allows organizations to manage and scale their networks through cloud providers.

Cloud networking shifts traditional networking services like routing, switching, and firewalls to virtualized environments in the cloud.

Definition of Cloud Networking

Cloud networking refers to the use of cloud services to handle network functions and resources.

It involves delivering network services over the internet or private cloud infrastructure.

This model provides network flexibility and efficiency by utilizing cloud-based resources rather than traditional hardware.

Types of Cloud Networks (Public, Private, Hybrid)

Cloud networks come in three main types: public, private, and hybrid.

Public Cloud Networks are hosted by third-party cloud providers like AWS, Google Cloud, and Microsoft Azure.

These networks offer shared resources and services over the internet.

They provide scalability and cost savings but may pose security concerns due to shared infrastructure.

Private Cloud Networks are dedicated to a single organization.

They can be hosted on-premises or by a third-party provider.

Private clouds offer enhanced security and control since the network is not shared with other organizations.

They are ideal for businesses with sensitive data or specific compliance requirements.

Hybrid Cloud Networks combine public and private cloud networks.

They allow organizations to leverage the benefits of both types.

This model provides flexibility, allowing businesses to keep sensitive data on a private cloud while using public cloud resources for scalability and cost-efficiency.

Benefits of Cloud Networking (Scalability, Flexibility, Cost-Efficiency)

Cloud networking offers several key benefits.
