2022 Global Networking Trends Report Summary

Core Content

The 2022 Global Networking Trends Report focuses on the rise of Network as a Service (NaaS) and its implications for modern network operations. The report outlines the challenges, benefits, and adoption trends associated with NaaS, emphasizing its role in enabling agility, innovation, and efficient management in a distributed computing landscape.

Main Points

1. NaaS Overview

• NaaS is a cloud-enabled, usage-based model that allows organizations to acquire and orchestrate network capabilities without owning or maintaining infrastructure.
• It supports a wide range of network elements, including LANs, WANs, VPNs, and hybrid cloud environments.
• NaaS can enable new network models such as SASE (Secure Access Service Edge), which provides secure, on-demand access to cloud-based applications.

2. Key Findings

• Challenge 1: Network Resilience and Agility

  • 45% of IT professionals cite responding to disruptions as the top network challenge.
  • NaaS is seen as a solution for improving agility and resilience.

• Challenge 2: Technology Evolution

  • 35% of respondents view the need to deploy the latest networking technologies (Wi-Fi 6, SD-WAN, SASE, 5G, AI, etc.) as the top driver for NaaS adoption.

• Challenge 3: Service-Level Agreements (SLAs)

  • 48% of respondents consider network lifecycle management as the most important service from NaaS providers.
  • Other top services include network resiliency (42%) and monitoring and troubleshooting (38%).

• Concern 1: Loss of Control

  • 30% of IT professionals express concern about NaaS's ability to meet future demands.
  • 26% worry about security control, and 20% about performance control.

• Concern 2: Cost and Disruption

  • 28% of respondents cite cost and disruption as inhibitors to NaaS adoption.
  • Legacy systems and a preference for direct control over infrastructure are also factors.

• Benefit 1: Business Value and Innovation

  • 46% of IT professionals see NaaS as freeing up teams to focus on innovation and business value.
  • 45% of network practitioners and 40% of primary decision makers value improved response to disruptions.

• Benefit 2: Ecological Sustainability

  • 25% of network practitioners and 33% of primary decision makers see improved ecological sustainability as a key benefit of NaaS.

• Role Shift

  • 75% of organizations believe NaaS will give their teams opportunities to upskill and deliver more value.
  • IT teams are expected to shift from infrastructure management to defining and monitoring network outcomes, such as access policies and performance levels.

3. Adoption Trends

• Best Timing for Adoption

  • 49% of IT leaders and 57% of network practitioners believe the best time for NaaS adoption is during a network refresh or upgrade.
  • 34% prefer adapting an existing (brownfield) site, while only 26% see a greenfield site as ideal.

• Preferred Deployment Approach

  • 23% of respondents favor a phased approach, upgrading domains one by one.

4. Choosing a NaaS Provider

• IT professionals are more likely to trust systems integrators or managed service providers over NaaS vendors.
• Key factors in choosing a provider include:
  • Global cloud footprint (31%)
  • Machine learning and AI capabilities (30%)
  • Consistent platform across domains (41%)
  • APIs, automation, and integrated security are also important.

5. SASE and NaaS

• SASE is seen as a likely entry point to NaaS, especially for multicloud access and security.
• 40% of organizations view multicloud access as the top priority for NaaS.
• 34% prioritize security-focused NaaS solutions, such as SIEM, secure web gateways, and IPS/IDS.

Key Information

• NaaS adoption is expected to grow at a 40.7% CAGR from 2021 to 2027.
• IT teams are shifting from "flying the plane" (infrastructure management) to "calling the shots" (strategic policy and design).
• Control and trust remain central concerns for IT leaders, with many preferring to work with trusted partners rather than relinquish full control.
• Financial benefits of NaaS are less emphasized compared to agility, innovation, and operational efficiency.
• Transitioning to NaaS is often seen as a way to reduce infrastructure management burdens and focus on strategic initiatives.

Conclusion

NaaS is transforming how organizations consume and manage network services, offering flexibility, scalability, and the ability to respond quickly to disruptions. While concerns about control, cost, and disruption persist, the trend is moving toward adoption, particularly in the context of SASE and multicloud environments. Organizations are increasingly looking for trusted partners who can provide the necessary expertise, integration, and support to ensure successful NaaS implementation.
