Description

Introduction

Network Virtualization and Software-Defined Networking (SDN) are the core enablers of Network as a Service (NaaS). They allow organizations to decouple network services from underlying physical hardware, creating programmable, flexible, and scalable network environments. This training is designed to provide IT professionals, network engineers, and architects with a deep understanding of virtualization concepts, SDN principles, and how these technologies form the foundation for NaaS deployments.

Participants will learn how to implement virtual networks, manage SDN controllers, and leverage automation to provision and optimize network services. The course also covers security, management, and operational aspects to ensure that NaaS solutions are efficient, resilient, and secure.

Prerequisites

• Basic networking knowledge (TCP/IP, routing, switching, LAN/WAN)

• Familiarity with cloud computing concepts (IaaS, PaaS, SaaS)

• Understanding of virtualization technologies (VMware, Hyper-V, Containers)

• Basic knowledge of cybersecurity principles
