Cloud Networking Basics
Cloud Networking basics refer to the core principles and components required to establish and manage network resources in a cloud environment. These include:
- **Virtualization: Creating virtual networks, subnets, and interfaces for flexible resource allocation and isolation.
- **Software-Defined Networking (SDN): Centralized control and automation of network configurations to improve agility and scalability.
- **Virtual Private Clouds (VPCs): Isolated network environments with custom IP ranges, subnets, and route tables for enhanced security and control.
- **Monitoring and Optimization: Using tools to track traffic, detect bottlenecks, and optimize performance and resource utilization.
- **Load Balancing: Distributing traffic across multiple servers to ensure performance, scalability, and fault tolerance.
Types Of Cloud Networking
The following are the types of cloud networking:
1. Single Cloud Networking
Cloud Networking comes with utilizes virtualized networking technologies to manage network resources within a cloud environment, providing scalability and centralized management.
- **Virtualized Infrastructure: It involves utilization of virtualized networking technologies for creating and managing the network resources over the cloud.
