VNFs on public cloud: Opportunity, not threat

VNF deployments on the hyperscale cloud are just beginning

Numerous collaboration agreements between hyperscalers and leading telcos, but few live VNF deployments to date

The past three years have seen many major telcos concluding collaboration agreements with the leading hyperscalers. These have involved one or more of five business models for the telco-hyperscaler relationship that we discussed in a previous report, and which are illustrated below:

In this report, we focus more narrowly on the deployment, delivery and operation by and to telcos of virtualised and cloud-native network functions (VNFs / CNFs) over the hyperscale public cloud. To date, there have been few instances of telcos delivering live, commercial services on the public network via VNFs hosted on the public cloud. STL Partners’ Telco Cloud Deployment Tracker contains eight examples of this, as illustrated below:

Telcos are looking to generate returns from their telco cloud investments and maintain control over their ‘core business’

The telcos in the above table are all of comparable stature and ambition to the likes of AT&T and DISH in the realm of telco cloud but have a diametrically opposite stance when it comes to VNF deployment on public cloud. They have decided against large-scale public cloud deployments for a variety of reasons, including:

  • They have invested a considerable amount of money, time and human resources on their private clouddeployments, and they want and need to utilise the asset and generate the RoI.
  • Related to this, they have generated a large amount of intellectual property (IP) as a result of their DIY cloud– and VNF-development work. Clearly, they wish to realise the business benefits they sought to achieve through these efforts, such as cost and resource efficiencies, automation gains, enhanced flexibility and agility, and opportunities for both connectivityand edge compute service innovation. Apart from the opportunity cost of not realising these gains, it is demoralising for some CTO departments to contemplate surrendering the fruit of this effort in favour of a hyperscaler’s comparable cloud infrastructure, orchestration and management tools.
  • In addition, telcos have an opportunity to monetise that IP by marketing it to other telcos. The Rakuten Communications Platform (RCP) marketed by Rakuten Symphony is an example of this: effectively, a telco providing a telco cloud platform on an NFaaS basis to third-party operators or enterprises – in competition to similar offerings that might be developed by hyperscalers. Accordingly, RCP will be hosted over private cloud facilities, not public cloud. But in theory, there is no reason why RCP could not in future be delivered over public cloud. In this case, Rakuten would be acting like any other vendor adapting its solutions to the hyperscale cloud.
  • In theory also, telcos could also offer their private telcoclouds as a platform, or wholesale or on-demand service, for third parties to source and run their own network functions (i.e. these would be hosted on the wholesale provider’s facilities, in contrast to the RCP, which is hosted on the client telco’s facilities). This would be a logical fit for telcos such as BT or Deutsche Telekom, which still operate as their respective countries’ communications backbone provider and primary wholesale provider

BT and Deutsche Telekom have also been among the telcos that have been most visibly hostile to the idea of running NFs powering their own public, mass-market services on the public and hyperscale cloud. And for most operators, this is the main concern making them cautious about deploying VNFs on the public cloud, let alone sourcing them from the cloud on an NFaaS basis: that this would be making the ‘core’ telco business and asset – the network – dependent on the technology roadmaps, operational competence and business priorities of the hyperscalers.

Fixed wireless access growth: To 20% homes by 2025

Fixed wireless access growth forecast

Fixed Wireless Access (FWA) networks use a wireless “last mile” link for the final connection of a broadband service to homes and businesses, rather than a copper, fibre or coaxial cable into the building. Provided mostly by WISPs (Wireless Internet Service Providers) or mobile network operators (MNOs), these services come in a wide range of speeds, prices and technology architectures.

Some FWA services are just a short “drop” from a nearby pole or fibre-fed hub, while others can work over distances of several kilometres or more in rural and remote areas, sometimes with base station sites backhauled by additional wireless links. WISPs can either be independent specialists, or traditional fixed/cable operators extending reach into areas they cannot economically cover with wired broadband.

There is a fair amount of definitional vagueness about FWA. The most expansive definitions include cheap mobile hotspots (“Mi-Fi” devices) used in homes, or various types of enterprise IoT gateway, both of which could easily be classified in other market segments. Most service providers don’t give separate breakouts of deployments, while regulators and other industry bodies report patchy and largely inconsistent data.

Our view is that FWA is firstly about providing permanent broadband access to a specific location or premises. Primarily, this is for residential wireless access to the Internet and sometimes typical telco-provided services such as IPTV and voice telephony. In a business context, there may be a mix of wireless Internet access and connectivity to corporate networks such as VPNs, again provided to a specific location or building.

A subset of FWA relates to M2M usage, for instance private networks run by utility companies for controlling grid assets in the field. These are typically not Internet-connected at all, and so don’t fit most observers’ general definition of “broadband access”.

Usually, FWA will be marketed as a specific service and package by some sort of network provider, usually including the terminal equipment (“CPE” – customer premise equipment), rather than allowing the user to “bring their own” device. That said, lower-end (especially 4G) offers may be SIM-only deals intended to be used with generic (and unmanaged) portable hotspots.
There are some examples of private network FWA, such as a large caravan or trailer park with wireless access provided from a central point, and perhaps in future municipal or enterprise cellular networks giving fixed access to particular tenant structures on-site – for instance to hangars at an airport.

FWA today

Today, fixed-wireless access (FWA) is used for perhaps 8-9% of broadband connections globally, although this varies significantly by definition, country and region. There are various use cases (see below), but generally FWA is deployed in areas without good fixed broadband options, or by mobile-only operators trying to add an additional fixed revenue stream, where they have spare capacity.

Fixed wireless internet access fits specific sectors and uses, rather than the overall market

FWA Use Cases

Source: STL Partners

FWA has traditionally been used in sparsely populated rural areas, where the economics of fixed broadband are untenable, especially in developing markets without existing fibre transport to towns and villages, or even copper in residential areas. Such networks have typically used unlicensed frequency bands, as there is limited interference – and little financial justification for expensive spectrum purchases. In most cases, such deployments use proprietary variants of Wi-Fi, or its ill-fated 2010-era sibling WiMAX.

Increasingly however, FWA is being used in more urban settings, and in more developed market scenarios – for example during the phase-out of older xDSL broadband, or in places with limited or no competition between fixed-network providers. Some cellular networks primarily intended for mobile broadband (MBB) have been used for fixed usage as well, especially if spare capacity has been available. 4G has already catalysed rapid growth of FWA in numerous markets, such as South Africa, Japan, Sri Lanka, Italy and the Philippines – and 5G is likely to make a further big difference in coming years. These mostly rely on licensed spectrum, typically the national bands owned by major MNOs. In some cases, specific bands are used for FWA use, rather than sharing with normal mobile broadband. This allows appropriate “dimensioning” of network elements, and clearer cost-accounting for management.

Historically, most FWA has required an external antenna and professional installation on each individual house, although it also gets deployed for multi-dwelling units (MDUs, i.e. apartment blocks) as well as some non-residential premises like shops and schools. More recently, self-installed indoor CPE with varying levels of price and sophistication has helped broaden the market, enabling customers to get terminals at retail stores or delivered direct to their home for immediate use.

Looking forward, the arrival of 5G mass-market equipment and larger swathes of mmWave and new mid-band spectrum – both licensed and unlicensed – is changing the landscape again, with the potential for fibre-rivalling speeds, sometimes at gigabit-grade.
