Applying Cloud native principles to all layers of network infrastructure, applications and services as put forth from the NGMN:
...
"For the new model to work, vendors and CSPs must provide mutual SLAs: the CSP must guarantee a certain level of quality at the platform layer, while CNF vendors need to guarantee that the application will perform on the platform with SLAs that meet defined KPIs.Challenges in Cloud Native Telco Transformation Today (source: Accelerating Cloud Native in Telco whitepaper *)"https://github.com/cncf/cnf-wg/blob/main/doc/whitepaper/Accelerating_Cloud_Native_in_Telco.md
"We also use the term cloud-native infrastructure in broader context for the infrastructure that abstracts Infrastructure-as-a-Service (IaaS) layer, that has Kubernetes in its core with useful API abstractions on top of it as as well as auxiliary systems all as a framework that makes managing applications easier and promotes doing so in a cloud native way. This is important because you are free to use Kubernetes (and other "cloud native" technologies) in a very uncloud-native way. Our longer-term goal, underlying this whitepaper, is for all layers of the environment to encompass the cloud native principles from infrastructure allocation + management, through the application workloads"

Fragmentation of all layers and a need for change in the deployment model
This is a list of modified challenges based on a Sylva article. This Cloud Native Telecom program can be part of solving these solutions.
- Sharing CaaS and physical resources among different applications to reduce wasted compute power with CAPEX and energy impacts
- Complexity for vendors trying to provide multiple cloud platform support
- Operational burdens on Telcos as the different “islands” will need different skills and will evolve at different speeds
- Solutions that can evolve with the necessary speed of cloud native
"if the Telco industry continues with its traditional deployment model then fragmentation is inevitable for the deployment of applications that mandate the use of proprietary CaaS (Container as a Service) and even specific physical compute." https://the-mobile-network.com/2022/11/why-the-eu-big-five-are-launching-sylva/
