Eyal Shaked gives his view on how 5G takes hyperscaler and telco cooperation to the next level.

5G, Telcos, and the Cloud

Telcos are no strangers to cloud. Major telcos around the globe operate proprietary clouds that provide the network functions virtualization infrastructure (NFVI) for software-defined networking (SDN) and virtual network functions (VNFs)—all of which allow telcos to deliver agile, flexible, and reliable network services. The emergence of cloud-native network functions (CNFs) that run inside containers (versus VNFs that run on VMs) is yet another important milestone on the telco journey toward cloud-native architectures. 

Recently, the rolling out of their 5G Cores has made it compellingly clear to telcos that strategic partnerships with public cloud hyperscalers can accelerate their time-to-value. The stakes are high, considering the wide range of 5G use cases to be fulfilled, from content delivery and augmented/virtual reality to IoT-based smart vertical solutions and driverless cars. But telcos are also wary of the dangerous impact this kind of strategic cooperation can have on their place in the value chain—reducing them to a “dumb pipe” while hyperscalers provide all the value-added services. 

This blog post describes the 5G rollout challenges and brings real-life examples that demonstrate the benefits to telcos (and hyperscalers) of these 5G core-to-edge partnerships. It also describes the Amdocs’ network and service orchestration platform, which is already integrated with both AWS and Azure. 

5G rollout challenges

R&D on 5G started in earnest a little less than 10 years ago, just as 4G LTE network rollouts were being completed. Forward-looking CSPs, network appliance vendors, mobile and IoT device OEMs, cloud-native application vendors, and hyperscalers began working together to make 5G a reality, with its promise of:

  • Ubiquitous and super-fast internet access
  • Huge bandwidth to handle the endless two-way flow of big data
  • Multi-access Edge Computing (MEC) to support high-performance edge computing at scale
  • Network slicing from core to edge to facilitate use-case-based SLAs
  • Ultra-Reliable Low-Latency Communication (URLLC) for mission-critical applications
  • The agility and flexibility of a cloud-native microservice-based architecture

However, as the CSPs progress along the path to full-fledged, standalone, high-band 5G networks, they find themselves facing the following challenges:

  • Complexity: Telcos and CSPs need to operate and maintain complex networks that encompass 3G, 4G, and 5G. This complexity creates infrastructure, software, and operational bottlenecks that constrain new initiatives.
  • Lack of agility: For the most part, telcos and CSPs still use legacy maintenance processes that cannot keep up with the speed and flexibility of a 5G network.
  • Growing strength of over-the-top (OTT) players: 5G network capabilities further strengthen the OTT players, who have already disrupted traditional telco (and broadcast) business models by decoupling content, messaging, and voice/video services from the infrastructure over which they are delivered.
  • Emergence of private mobile networks and innovative startups: The unprecedented move to open up 5G spectrums—such as the Citizens Broadband Radio Service (CBRS) "innovation band" in the U.S. or the industrial spectrums in Germany and Japan—encourages the launch of innovative 5G apps and services that run on their own 5G network. It also allows enterprises to create dedicated 5G networks.

CSPs can address many of these challenges by partnering with hyperscalers to leverage their scalable and reliable core-to-edge infrastructures, cost-effective on-demand business models, fully managed platforms, and rich partner ecosystems. However, these partnerships are a double-edged sword because value propositions become blurred as hyperscalers and telcos start to offer overlapping and competing services. A classic example is AWS’ recent announcement of their own fully managed AWS Private 5G network.

The multi-billion-dollar question becomes, how can CSPs cooperate with hyperscalers without undermining their own position in the value chain?

Examples of CSP/Hyperscaler 5G Partnerships

Below, we present two case studies that illustrate how leading CSPs such as AT&T and DISH are forging strategic partnerships with cloud hyperscalers in order to accelerate and enrich their 5G deployments. With these partnerships, everybody wins: The CSP leverages proven hyperscaler infrastructure resources and managed services, the hyperscaler becomes a part of the 5G value chain, and third parties get a powerful end-to-end platform for bringing innovative 5G applications to market.

AT&T and Azure

To date, AT&T has virtualized 75% of its network functions, making it an industry leader in software-defined networking (SDN). It has also been a major contributor to pivotal and innovative open-source projects such as ONAP (Open Network Automation Platform), DANOS (Disaggregated Network Operation System), and Akraino (open blueprints for edge computing systems and applications).

In July 2021, AT&T announced that it will be hosting its 5G mobile network on the Microsoft Azure for Operators cloud. According to the terms of the agreement, Microsoft and AT&T personnel will work closely together, leveraging AT&T’s considerable SDN-related IP. Microsoft will be responsible for delivering a high-performance network cloud on which AT&T will directly manage its subscriber data as well as its network and application deployments—including the rollout of its 5G services.

The key benefits of this hyperscaler/telco partnership are:

  • AT&T’s expertise and experience will accelerate the evolution of Microsoft Azure for Operators, for the benefit of all CSPs making the transition to 5G.
  • AT&T can concentrate on building out its cloud-native 5G network at scale.
  • Each side brings a rich partner network and substantial enterprise customer base to the table, for best-of-breed synergies and new business opportunities.


DISH Network Corporation (NASDAQ: DISH) was established in 1980 as a connectivity company with a focus on satellite television. Since 2020, it has been a U.S.-wide wireless carrier, starting with its acquisition of Sprint’s prepaid business division.

In April 2021, DISH and AWS announced a strategic collaboration whereby AWS will host DISH’s standalone, cloud-based 5G O-RAN (Open Radio Access Network) in the U.S. Leveraging AWS Local Zones (enabling the deployment of AWS services on infrastructure that is close to end users) and AWS Outposts (fully managed AWS infrastructure, services, and APIs deployed on-premises or at the edge), DISH will deploy its 5G Core at the edge for reliable and consistent low-latency performance. The first city to go live will be Las Vegas, in early 2022.

The key benefits of this hyperscaler/CSP partnership are:

  • DISH can leverage AWS’ compute, container, IoT, machine learning, and security capabilities to cost-effectively run its 5G Core and its business and operations systems (BSS/OSS) at scale.
  • DISH can cooperate with AWS Professional Services and AWS’ telco partners to achieve high levels of automation in deploying 5G network slices to meet tailored SLAs and use cases.
  • Developers can take advantage of the combined DISH/AWS capabilities to quickly bring innovative 5G applications to market.

Given the cloud-native architecture of 5G Core and the data-intensive, cloud-to-edge use cases it is designed to support, it is not surprising that strategic partnerships are being forged between public cloud hyperscalers and telcos as 5G networks are rolled out around the globe. 5G is forcing telcos out of their private cloud comfort zones as they seek to accelerate the ROI on their huge investments in 5G networking infrastructure and operational services.

However, these partnerships are a double-edged sword. On the one hand, they help the telcos overcome the complexity of operating multi-generational networks; embrace more agile and flexible provisioning and maintenance processes; and stay competitive in the face of 5G-empowered OTT players, private mobile networks, and innovative startups. On the other hand, the partnerships could obscure the unique role of the telcos in 5G value creation and constrain their positioning in the new 5G economy.
