IDC Forecasts Carrier VNF/CNF and NFVI Markets to Grow from $7.5 Billion in 2020 to More Than $29 Billion in 2025 as Telco Cloud Rollouts Rapidly Increase

NEEDHAM, Mass., May 26, 2021 – International Data Corporation (IDC) forecasts worldwide revenue for telecommunications network functions virtualization (NFV) software, including virtual network functions (VNFs), network functions virtualization infrastructure (NFVI), and cloud-native network functions (CNFs), will grow from a combined $7.5 billion in 2020 to just over $29 billion in 2025. This represents a compound annual growth rate (CAGR) of 30.9% over the 2020-2025 forecast period.

Despite the sustained headwinds from COVID-19 in 2020, communications service providers (SPs) continued to deploy VNFs as an adjunct to legacy physical network functions. Additionally, the broader industry witnessed early instances of CNFs deployed in containers, primarily tied to the standalone 5G core as part of mobile network upgrades, giving rise to telco cloud infrastructure. However, IDC does not expect material uptake for CNFs across comms SPs (wireless and wireline) until the latter part of the forecast.

While the VNF/CNF and NFVI markets have generally underperformed against expectations thus far, we expect 5G network rollouts to positively impact uptake, particularly across the latter portion of the forecast. Additionally, virtualization is incrementally seeing uptake across the core transport network, mobile backhaul, access network (cable and PON) and virtual CPE markets, particularly as multi-access edge computing (MEC) initiatives take hold.

"Communications SPs globally continue to gradually embrace network virtualization technologies driven by the lower cost of ownership and elastic scaling of the network," said Ajeet Das, research director, Carrier Network Infrastructure research at IDC. "Cloud-native network functions are now slowly being deployed alongside virtual network functions across cloud-based digital infrastructure so that the customer-centric services can be scaled, updated, and orchestrated easily, not only at the core but also at the edge of the network."

The IDC report, Worldwide Telecom Network Functions Virtualization Software (VNF and NFVI) Forecast, 2021–2025 (IDC # US47662821), presents the worldwide market forecast for telecom network functions virtualization software (VNF and NFVI) for the 2021–2025 period. As part of the forecast, IDC breaks out VNF/CNF spending across the core transport, mobile, mobile backhaul, access, and CPE domains, with further breakouts in each segment. (e.g. vRAN). For NFVI, IDC breaks out spending across key segments such as the faster-growing virtual infrastructure management (VIM) and orchestration domains, as well as traditional infrastructure segments (e.g., software-defined infrastructure). The report also provides a market overview, including drivers and challenges for communications service providers and advice for technology suppliers.
