The term Network as a service (NaaS) is often used alongside other marketing terms such as cloud computing. It is related to concepts like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Software-Defined Networking (SDN), and internet exchange points. [1]
"Network-as-a-Service" (NaaS) is often used alongside other marketing terms such as cloud computing. It is related to terms like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Software-Defined Networking (SDN).
Historic definitions focused on fundamental concepts of NaaS, including describing services for network transport connectivity. [2] NaaS also involves the optimization of resource allocations by considering network and computing resources as a unified whole. [3]
The term network-as-a-service (NaaS) is often used alongside other marketing terms like cloud computing, along with terms such as infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and software-defined networking. [2] [4]
With the emergence of cloud computing, NaaS has become the transport not only between dynamic collaborators outside of the cloud (an update to the classic enterprise WAN architecture), but also between enterprise resources in private (often multi-tenant) data center facilities (MTDCs) and in the public Cloud Service Providers (CSPs), including the interconnection between all of these in a growing "cloud first" enterprise architecture.
Before the new WAN connectivity patterns, enterprise WAN architectures and consumption models resulting from the adoption of cloud computing and the network programmability focus introduced by SDN, NaaS was sometimes used to describe more traditional network resource-sharing concepts like the provision of a virtual network service by the owners of the network infrastructure to a third party. [5]
Some service models include: [2] [6]
Software as a service is a form of cloud computing in which the provider offers the use of application software to a client and manages all the physical and software resources used by the application. The distinguishing feature of SaaS compared to other software delivery models is that it separates "the possession and ownership of software from its use". SaaS began around the turn of the twenty-first century and became the main form of software application deployment by 2023.
A virtual appliance is a pre-configured virtual machine image, ready to run on a hypervisor; virtual appliances are a subset of the broader class of software appliances. Installation of a software appliance on a virtual machine and packaging that into an image creates a virtual appliance. Like software appliances, virtual appliances are intended to eliminate the installation, configuration and maintenance costs associated with running complex stacks of software.
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s), and to allow developers to create, develop, and package such software bundles.
Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users.
Hewlett Packard Enterprise Networking is the Networking Products division of Hewlett Packard Enterprise. HPE Networking and its predecessor entities have developed and sold networking products since 1979. Currently, it offers networking and switching products for small and medium sized businesses through its wholly owned subsidiary Aruba Networks. Prior to 2015, the entity within HP which offered networking products was called HP Networking.
FUJITSU Cloud IaaS Trusted Public S5 is a Fujitsu cloud computing platform that aims to deliver standardized enterprise-class public cloud services globally. It offers Infrastructure-as-a-Service (IaaS) from Fujitsu's data centres to provide computing resources that can be employed on-demand and suited to customers needs.
Software-defined networking (SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. SDN is meant to improve the static architecture of traditional networks and may be employed to centralize network intelligence in one network component by disassociating the forwarding process of network packets from the routing process. The control plane consists of one or more controllers, which are considered the brains of the SDN network, where the whole intelligence is incorporated. However, centralization has certain drawbacks related to security, scalability and elasticity.
IT as a service (ITaaS) is an operational model where the information technology (IT) service provider delivers an information technology service to a business. The IT service provider can be an internal IT organization or an external IT services company. The recipients of ITaaS can be a line of business (LOB) organization within an enterprise or a small and medium business (SMB). The information technology is typically delivered as a managed service with a clear IT services catalog and pricing associated with each of the catalog items. At its core, ITaaS is a competitive business model where businesses have many options for IT services and the internal IT organization has to compete against those other external options in order to be the selected IT service provider to the business. Options for providers other than the internal IT organization may include IT outsourcing companies and public cloud providers.
Cloud computing architecture refers to the components and subcomponents required for cloud computing. These components typically consist of a front end platform, back end platforms, a cloud based delivery, and a network. Combined, these components make up cloud computing architecture.
openQRM is a free and open-source cloud-computing management platform for managing heterogeneous data centre infrastructures.
HP Cloud was a set of cloud computing services available from Hewlett-Packard. It was the combination of the previous HP Converged Cloud business unit and HP Cloud Services, an OpenStack-based public cloud. It was marketed to enterprise organizations to combine public cloud services with internal IT resources to create hybrid clouds, or a mix of private and public cloud environments, from around 2011 to 2016.
Cloud-based integration is a form of systems integration business delivered as a cloud computing service that addresses data, process, service-oriented architecture (SOA) and application integration.
Network functions virtualization (NFV) is a network architecture concept that leverages IT virtualization technologies to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create and deliver communication services.

PaaSage is a notable example of European research efforts in the field of Infrastructure as a Service (IaaS).
Computation offloading is the transfer of resource intensive computational tasks to a separate processor, such as a hardware accelerator, or an external platform, such as a cluster, grid, or a cloud. Offloading to a coprocessor can be used to accelerate applications including: image rendering and mathematical calculations. Offloading computing to an external platform over a network can provide computing power and overcome hardware limitations of a device, such as limited computational power, storage, and energy.

"X as a service" is a phrasal template for any business model in which a product use is offered as a subscription-based service rather than as an artifact owned and maintained by the customer. Originating from the software as a service concept that appeared in the 2010s with the advent of cloud computing, the template has expanded to numerous offerings in the field of information technology and beyond it. The term XaaS can mean "anything as a service".

A secure access service edge (SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection rather than a data center. It uses cloud and edge computing technologies to reduce the latency that results from backhauling all WAN traffic over long distances to one or a few corporate data centers, due to the increased movement off-premises of dispersed users and their applications. This also helps organizations support dispersed users and their devices with digital transformation and application modernization initiatives.
