Network as a Service (NaaS) is a cloud computing service model that provides virtualized networking capabilities to businesses. In this chapter, we will explore NaaS and its significance in enabling flexible and scalable network infrastructure.
- Introduction to NaaS: We will introduce NaaS and its role in delivering networking services through the cloud. We will discuss how NaaS providers abstract the underlying network infrastructure and offer virtualized network resources as a service, providing businesses with flexibility and cost savings.
- Key Features: We will discuss the key features of NaaS, such as virtual private networks (VPNs), bandwidth allocation, and network monitoring. We will explain how NaaS allows businesses to dynamically provision and manage their network resources based on their requirements.
- Benefits of NaaS: This section will highlight the benefits of NaaS for businesses. We will discuss how NaaS enables businesses to scale their network infrastructure as needed, reduce capital expenditures (CapEx), and optimize network performance through advanced monitoring and management capabilities.
- Use Cases: We will explore various use cases where NaaS can be advantageous. This may include scenarios such as branch office connectivity, remote workforce support, software-defined wide area networks (SD-WAN), and network segmentation for improved security. We will discuss how NaaS addresses the specific networking needs of these use cases.
- Popular NaaS Providers: We will provide an overview of popular NaaS providers in the market, such as Cisco Meraki, Aryaka, and VMware NSX. We will highlight their key offerings, network management features, and integration capabilities, enabling businesses to make informed decisions when selecting a NaaS provider.
