Cisco Cloud Services Stack for Mobility is a complete mobile core solution
With the continued expansion of 5G, many service providers struggle to design and operationalize the complex solutions presented by new virtualized and cloud-based technologies. Both 5G and 4G technology rely on cloud-based solutions that carry the promise of more flexible service architectures.
But unlike the “single box” physical appliances of the past, Telco Cloud infrastructure is difficult to implement and carries many hidden costs, particularly when service providers are mixing and matching devices and building unique stacks of their own in Do It Yourself (DIY) fashion. This hodge-podge of individual products adds risk, slows down time to market, and increases both upfront costs and those accrued over time.
Service providers are under continuous pressure to increase network capacity as they seek to keep their 4G customers happy while making a successful transition to 5G. They want to know the best way to accomplish this both quickly and easily.
It’s one thing to do your research, order your products, and have seven or eight devices show up in your loading bay. But it’s quite another thing to design, integrate, and test all these components in order to achieve a working, carrier-grade packet core network.
In response, Cisco recently introduced a predesigned, pre-validated, and pre-characterized packet core solution for 4G and 5G mobile core implementations. Cisco Cloud Services Stack for Mobility is an exciting solution for service providers because it offers the building block to get to market quickly and easily without the struggle of integrating and testing many different products into a fully operational system. This solution is made specifically for service providers who are rethinking their custom stack, those who seek to expand capacity on their 4G network, and those looking to introduce cloud-native 5G services.
Estimates show today’s $53 billion 5G marketplace for service provider-delivered services more than doubling to $123 billion by 20251. Our technology stack solution is designed to address this massive expansion.
5G infrastructure development is enabled by Network Function Virtualizations (NFV) and Service Provider Private Cloud. This is also called Telco Cloud – a unified operational environment designed to achieve the benefits of a service provider infrastructure such that each new service and application can leverage the platform investment and simplified operational processes. It is the hardware and software infrastructure supporting flexible and efficient deployment of the applications that service providers use to manage and deliver those services.
Cisco Cloud Services Stack for Mobility utilizes key industry-standard capabilities, fully featured mobile packet core software, and our extensive experience designing, leveraging, and troubleshooting issues for a faster rollout of new services and improved long-term Total Cost of Ownership (TCO). Customers also benefit from Cisco Solution Support that centralizes technical support across all hardware and software, resolving issues 44 percent faster than product support2.
Our solution gives service providers best-in-class components (both hardware and software), a pre-validated Cisco design blueprint as a building block for 4G and 5G deployments, and the option to onboard and integrate third-party Virtual Network Functions (VNFs) into your service architecture. It also offers pod deployment automation, large scale “hyperconverged” and smaller scale “micro-pod” variants with functional/scalable performance, and system-level security penetration testing.
Some may wonder what’s new in this package, since Cisco has always offered these components and services. What makes it unique is how we have put this solution together. It is specifically designed to save service providers the time and extra costs of systems testing, integration, and support. In this paper we compare Telco Cloud to Cisco Cloud Services Stack for Mobility and discuss some of the benefits of letting us build the technology stack for you.
Over the past several years, the Management and Organization Working Group of the European Telecommunications Standard Institute (ETSI MANO) has defined a standard for building Network Functions Virtualization Infrastructure (NFVI) networks. It divides the architecture into three major blocks: Virtual Infrastructure Manager (VIM), VNF manager, and NFV orchestrator. The VIM is a specific part of the MANO framework that controls and manages the NFVI compute, storage, and network resources. The goal of the original ETSI NFVI standards was to make it easier for service providers to combine different components from various telecommunications equipment manufacturers into a functioning network.
Many service providers jumped in with both feet to develop NFVI-based networks using best-in-class (and often disparate) technology stacks. They were lured by the promise of plug-and-play simplicity offering ease of use, cost efficiency, and scalability. Unfortunately, these promises did not always deliver for vendors, often due to the sheer complexity of it. A full network requires dozens or hundreds of NFVs running on multiple hardware types and automated/orchestrated by a variety of software systems, and the permutations for all these components quickly grow astronomical. While some service providers successfully built Telco Clouds, the projects nevertheless required advanced skillsets and large budgets, and this bar proved too high for many providers.
Some providers also struggled to define, integrate, and regression test best-of-breed custom stacks which led to higher integration costs, interoperability issues, and increased security risk. For example, debugging becomes much more complicated and components must be both maintained and tested in the service providers’ dedicated labs. The results were delayed product introductions and some cancelations, and even with successfully deployed programs, the increased complexity resulted in escalated long-term costs. Cobbling together DIY stacks can also become a hinderance to your roadmap. Take a closer look at some of the costs and challenges in Figure 1 below.
Figure 1. Challenges of Telco Cloud that Cisco Cloud Services Stack for Mobility addresses
A less obvious detraction of Telco Cloud is the subsequent post-procurement costs that service providers are required to budget for. These range from design and integration costs to security, performance, and scale testing, which can be quite extensive. In a DIY custom stack, the service provider is required to either resource the tasks themselves or pay a third-party systems integrator to deliver on the tasks. Cisco performs these activities in Cloud Services Stack for Mobility as part of the overall solution development and includes them as “no cost” options in the overall solution, so the service provider does not need to budget in advance for these fundamental project tasks.

Since the NFV architecture was formalized by ETSI, service providers have been mixing and matching different components from different manufacturers to build their own custom technology stacks. Unfortunately, this creates integration lifecycle management problems, as we discussed earlier, in all stages of the design, deployment, and operations lifecycle as illustrated in the picture below.
Figure 5: How complexity and integration costs compound in the virtualized world
Looking across our global installed base of virtualized packet core deployments, we’ve found that the more standardized a set of hardware and software components, the greater the reduction in complexity and resulting problems. Combining the right solution engineering with Cisco methodology and automation capabilities enables us to validate and secure the stack for easier deployment and more predictable outcomes. We can also focus testing on a smaller set of permutations and combinations to deliver quicker, more reliable results.
We designed Cisco Cloud Services Stack for Mobility from our direct experience using a Cisco best practices design blueprint. We combined our market-leading Cisco UPC, CVIM, UCS, and Cisco Nexus data center fabric into a single, out-of-the-box solution which is automated using Cisco NSO. This solution has undergone extensive system-level testing of functionality, scale, performance, and security penetration. The focus on standardization and complexity reduction can deliver big benefits. We have engineered the solution to drive down costs by 20-40 percent compared to full custom-stack deployments.
We’ve also invested heavily in driving down both deployment costs and timeframes of our professional services offers. Our investment in pre-validation testing and deployment automation is central to achieving optimized professional services delivery – and our Cisco Customer Experience professional services organization stands ready across the globe to help your project delivery. The expertise and track record of our technology consultants and solutions architects, which Cisco has scaled globally, is coupled with the investment to simplify and drive cost out of deployment. These investments will reduce risk and help drive towards on-time project delivery for the most aggressive rollouts.
Finally, the Cisco Cloud Services Stack for Mobility includes Cisco Solution Support which offers a primary technical support point of contact across all components of the stack. This results in up to 44 percent faster resolution times3 for complex issues compared to single-product support – with no need to play the frustrating “vendor blame game” that is so common in current generation Telco Cloud deployments.
There are plenty of valid reasons why service providers designed unique technology stacks in the past. Some will no doubt continue to try. But we believe the future lies in standardization and simplification. Our solution is designed to address the fundamental challenges of building NFVI-based 4G and 5G networks, so service providers get to market faster, with lower risk and less cost. Cisco Cloud Services Stack for Mobility helps overcome the challenges of Telco Cloud design, testing, and operations in the race for 5G.
