As cloud adoption turns into more and more mandatory for multinational enterprises, backend networks have gotten extra advanced.
The introduction of X-as-a-Service merchandise and the necessity for multi-cloud environments have pushed WAN managers to make modifications to their present ecosystems and undertake new applied sciences.
Let’s take a look at how community professionals are integrating the cloud and Networking-as-a-Service (NaaS) into their enterprise networks.
We’ll analyze survey outcomes on Infrastructure-as-a-Service (IaaS) adoption, IaaS associate decisions, information heart landscapes, the place corporations are connecting to their cloud service suppliers (CSPs), and NaaS adoption.
Infrastructure-as-a-Service
This yr, once we requested about IaaS suppliers, all survey members responded that they used no less than one IaaS supplier.
WAN managers have a plethora of IaaS suppliers to select from, together with Amazon Net Providers, Azure, Google, and others. AWS had the first-to-market benefit in IaaS companies. This yr, nonetheless, we discovered that WAN managers most often selected Microsoft Azure as an IaaS supplier (97%).

IaaS Connection Strategies
Whereas the general public web is commonly thought-about the default technique for reaching the cloud, corporations have many choices relying on their capability, efficiency, or safety necessities.
We requested WAN managers to pick all of the ways in which they linked to cloud service suppliers. We took our definitions for varied cloud connectivity companies from TeleGeography’s Cloud and WAN Infrastructure report.
The place are your information facilities positioned? (2022)

-
Virtually half of our respondents mentioned their information facilities have been positioned at a mixture of on-premises, impartial services, and personal or digital non-public cloud environments.
-
Respondents who reported utilizing all on-premise information facilities jumped from 11% in 2019 to 18% in 2022.
-
Almost a 3rd of respondents have been utilizing both non-public or off-premise cloud servers with some mixture of on-premise servers.
Networking-as-a-Service
That is the primary yr we requested about enterprises’ familiarity and method to NaaS. NaaS permits enterprises to eat community infrastructure by means of a subscription mannequin like cloud companies to satisfy enterprise wants and optimize community efficiency on an on-demand foundation.
The central thought of NaaS is that enterprises can eat community companies as wanted moderately than by means of a long-term contractual settlement. Key to this are portals the place enterprises can go browsing and allocate community connections right down to even an hourly foundation in some circumstances. Reasonably than weeks or months to spin up this service, it’s typically accessible instantly upon ordering.
That is inherently restricted to the core community and information heart visitors, as bandwidth-on-demand would not often be accessible right down to an area company website. Spine networks are over-provisioned sufficiently to accommodate just-in-time networks, however that is very not often going to be the case for final mile connections.
So NaaS is usually a service to attach issues like information facilities, massive name facilities, catastrophe restoration websites, and different sources positioned the place fiber property are extensively accessible–to not spin up service to everlasting department workplaces or native company websites.
Nonetheless, as final mile options like FTTx and 5G service turn into extra accessible, there are potential use circumstances for NaaS at places akin to pop-up occasions and even short-term websites.
This yr, we discovered that whereas NaaS merchandise can be found in the marketplace, few enterprises have bought them.
This yr, we discovered that whereas NaaS merchandise can be found in the marketplace, few enterprises have bought them. Whereas some are within the analysis section, most are nonetheless finally unfamiliar with these merchandise.
NaaS Stage of Adoption (2022)
Notes: Every bar demonstrates the proportion of all legitimate respondents in 2022 who’re in every stage NaaS/center mile options adoption. Supply: © 2023 TeleGeography
-
A minority of respondents–solely 5%–have bought and are actively utilizing NaaS options.
-
Three in ten respondents have heard of NaaS/center mile however have but to analysis them, whereas virtually 40% of respondents weren’t conversant in these options in any respect.
-
One in ten respondents has researched NaaS/center mile and determined to not use them.
Within the coming years, we anticipate to see an uptick within the adoption of NaaS as the subsequent main growth within the WAN market. That is very true as enterprises proceed to maneuver away from on-prem information facilities and put extra enterprise and workloads within the cloud.
With the ability to shift round sources on an as-needed foundation—moderately than vastly over-provisioning for uneven workloads—is vital to digital transformation.
This evaluation was pulled from our newest WAN Supervisor Survey—which now consists of information collected all through 2022.
