Making Sense of the Telco Cloud

In recent years the cloudification of communication networks, or “telco cloud” has become a byword for telecom modernisation. This Telecoms.com Intelligence Monthly Briefing aims to analyse what telcos’ transition to cloud means to the stakeholders in the telecom and cloud ecosystems. Before exploring the nooks and crannies of telco cloud, however, it is worthwhile first taking an elevated view of cloud native in general. On one hand, telco cloud is a subset of the overall cloud native landscape, on the other, telco cloud almost sounds an oxymoron. Telecom operator’s monolithic networks and cloud architecture are often seen as two different species, but such impressions are wrong.

(Here we are sharing the opening section of this Telecoms.com Intelligence special briefing to look into how telco cloud has changing both the industry landscape and operator strategies.

What cloud native is, and why we need it

“Cloud native” have been buzz words for a couple of years though often, like with many other buzz words, different people mean many different things when they use the same term. As the authors of a recently published Microsoft ebook quipped, ask ten colleagues to define cloud native, and there’s good chance you’ll get eight different answers. (Rob Vettor, Steve “ardalis” Smith: Architecting Cloud Native .NET Applications for Azure, preview edition, April 2020)

Here are a couple of “cloud native” definitions that more or less agree with each other, though with different stresses.

The Cloud Native Computing Foundation (CNCF), an industry organisation with over 500 member organisations from different sectors of the industry, defines cloud native as “computing (that) uses an open source software stack to deploy applications as microservices, packaging each part into its own container, and dynamically orchestrating those containers to optimize resource utilization.”

Gabriel Brown, an analyst from Heavy Reading, has a largely similar definition for cloud native, though he puts it more succinctly. For him, cloud native means “containerized micro-services deployed on bare metal and managed by Kubernetes”, the de facto standard of container management.

Although cloud native has a strong inclination towards containers, or containerised services, it is not just about containers. An important element of cloud native computing is in its deployment mode using DevOps. This is duly stressed by Omdia, a research firm, which prescribes cloud native as “the first foundation is to use agile methodologies in development, building on this with DevOps adoption across IT and, ideally, in the organization as well, and using microservices software architecture, with deployment on the cloud (wherever it is, on-premises or public).”

Some would argue the continuous nature of DevOps is as important to cloud native as the infrastructure and containerised services. Red Hat, an IBM subsidiary and one of the leading cloud native vendors and champions for DevOps practices, sees cloud native in a number of common themes including “heavily virtualized, software-defined, highly resilient infrastructure, allowing telcos to add services more quickly and centrally manage their resources.”

These themes are aligned with the understanding of cloud native by Telecoms.com Intelligence, and this report will discuss cloud native and telco cloud along this line. (A full Q&A with Azhar Sayeed, Chief Architect, Service Provider at Red Hat can be found at the end of this report).

The main benefits of cloud native computing are speed, agility, and scalability. As CNCF spells it out, “cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.”

To adapt such thinking to the telecom industry, the gains from migrating to cloud native are primarily a reflection of, and driven by, the increasing convergence between network and IT domains. The first candidate domain that cloud technology can vastly improve on, and to a certain degree replace the heavy infrastructure, is the support for the telcos’ own IT systems, including the network facing Operational Support Systems and customer facing Business Support System (OSS and BSS).

But IT cloud alone is far from what telcos can benefit from the migration to cloud native. The rest of this report will discuss how telcos can and do embark on the journey to cloud native, as a means to deliver true business benefits through improved speed, agility, and scalability to their own networks and their customers.
