Top Trending 2022

The WAN edge infrastructure choices made by infrastructure and operations leaders in charge of networking are influenced by digital transformation, remote work, and cloud adoption. To connect company sites and applications, they ought to choose SD-WAN solutions and SASE deployments.

Strategic Planning Assumptions
> Compared to 2021, when just 40% of software-defined wide-area network (SD-WAN) clients had adopted a secure access service edge (SASE) architecture, that number will rise to over 70% by 2024.
> In comparison to less than 5% in 2021, 40% of organisations with SD-WAN deployments will leverage AI functions to automate Day 2 operations by 2025.
> By 2025, compared to 15% in 2021, 40% of company locations would only have internet WAN access in order to give flexible, cost-effective scalable capacity.

Definition/Description of the Market
The wide-area network (WAN) edge infrastructure market, consists of goods and related services that offer network connectivity over WANs. This allows remote employees and scattered corporate locations (headquarters, hubs, branches, and remote workers) to access resources in private data centres as well as infrastructure as a service (IaaS) and software as a service (SaaS). The most well-known goods connected with this sector are routers and SD-WAN equipment (both physical and virtual).

The old branch routers (commonly referred to as "customer edge routers" in an MPLS implementation) used to connect branch locations to the data centre are still being phased out in favour of SD-WAN, which has a more decentralised design and supports cloud applications. Edge routers are frequently being replaced with SD-WAN, which also adds native security, centralised orchestration, application-aware path selection across multiple networks, and other services for improving application performance (such as WAN optimization). As a result, it contains established and up-and-coming suppliers from related industries (such as routing, security, WAN optimization, and SD-WAN), each with unique strengths and weaknesses. As part of SASE, which integrates SD-WAN and cloud security into an integrated, orchestrated architecture, it also incorporates zero trust network access (ZTNA) functionality for remote workers in place of conventional virtual private network (VPN) solutions.

On-premises or off-premises WAN edge infrastructure capability can be provided by hardware or software equipment. It is typically obtained via network service providers (NSPs), managed network service (MNS) providers, and network equipment providers (and their channels). Senior networking leaders and senior security leaders in the infrastructure and operations (I&O) group are often those who make the purchase.

The following are typical features of SD-WAN solutions:
> Core Functions
> Approved software
  > Routing (e.g., Border Gateway Protocol [BGP])
  > Path Choice (e.g., Layer 7 traffic steering)
  > VPN
  > Basic firewall

> Formal elements:
  > Software and/ or physical
  > Clients working remotely, branches, headends, and clouds

> (On-premises or in the cloud) Orchestrator:
  > Configuration (zero touch configuration)
  > Management
  > Visibility
  > Reporting
  > API adherence

An Optional Functionality
> Advanced protection (e.g., network firewalls, secure web gateways [SWGs], cloud access security brokers [CASB] and data loss prevention [DLP])
> Ability to chain services
> Cloud gateways for streamlined cloud connectivity and service insertion
> Performance capabilities for applications (e.g., WAN optimization and SaaS optimization)
> SD-Branch is created by the integration and orchestration of WLAN, LAN, security, and SD-WAN.
