What are the types of enterprise computer networks?

Depending on the organization's size and requirements, there are three common types of enterprise private networks:

Local area network (LAN)

A LAN is an interconnected system limited in size and geography. It typically connects computers and devices within a single office or building. It is used by small companies or as a test network for small-scale prototyping.

Wide area networks (WAN)

An enterprise network spanning buildings, cities, and even countries, is called a wide area network (WAN). While local area networks are used to transmit data at higher speeds within close proximity, WANs are set up for long-distance communication that is secure and dependable.

SD-WAN or software-defined WAN is virtual WAN architecture controlled by software technologies. An SD-WAN offers more flexible and dependable connectivity services that can be controlled at the application level without sacrificing security and quality of service.

Service provider networks

Service provider networks allow customers to lease network capacity and functionality from the provider. Network service providers may consist of telecommunications companies, data carriers, wireless communications providers, Internet service providers, and cable television operators offering high-speed Internet access.

Cloud networks

Conceptually, a cloud network can be seen as a WAN with its infrastructure delivered by a cloud-based service. Some or all of an organization’s network capabilities and resources are hosted in a public or private cloud platform and made available on demand. These network resources can include virtual routers, firewalls, bandwidth, and network management software,with other tools and functions available as required.

Businesses today use cloud networks to accelerate time-to-market, increase scale, and manage costs effectively. The cloud network model has become the standard approach for building and delivering applications for modern enterprises.
