Definition
Cloud networking refers to the design, implementation, and management of network infrastructure within a cloud computing environment. It involves configuring virtual networks, subnets, routing, firewalls, and load balancing to enable secure and efficient communication between cloud resources and on-premises systems. This is crucial for ensuring data flow, application accessibility, and overall system performance in the cloud. For instance, setting up a virtual private cloud (VPC) with specific security groups allows an organization to isolate its cloud resources from the public internet. Unlike traditional on-premises networking, cloud networking abstracts much of the physical hardware, offering greater flexibility and scalability. Understanding cloud networking is essential for AWS and CompTIA cloud certifications.
