…in introduction (#287) * Update Accelerating_Cloud_Native_in_Telco.md * Update Accelerating_Cloud_Native_in_Telco.md Fixing linux instead of Linus in the preamble + proposing a last sentence in the introduction to state that Kubernetes is the de facto runtime environment for hosting the CNF. Kubernetes as such is listed later on in the doc, but as mentioned in the thread with ildikov it may worth mentioning it.

+and relying on “rolling upgrades” to deploy changes. This paradigm is applied in both the lifecycle management of applications and 
+the cloud infrastructure. As a consequence, for example, Kubernetes cluster nodes can ordinarily have rather short uptime of several
+days to several weeks. This is in contrast with the traditional carrier-grade-driven focus on the uptime of individual system 
+elements. Although large parts of CNFs do not have problems with that cloud native lifecycle approach, we are experiencing that 


LCM is a separate topic , similarly Resilience (improve HA design) and Reliability . These all three should be placed as separate points for challenges .

+       human-readable open formats
+    1. The application must be isolated with Namespaces and not use the default namespace
+
+1. **Resilience.**  High-quality CNFs should be resilient to underlying infrastructure issues including complete failure,


Sugges to add one item on "Testing framework" i.e idea is all points above can be tested in an automated fashion and how we can achieve it

Add two more section on how to solve it

operational readiness
e.g in brownfield how we can integrate , co-exist it with existing tools and align with processess

Commercial models
do local tuning is a great way for Telco clouds but with Edge/RAN it is important that we test once and deploy in a scalable manner , even those deployments need to be tested . so defining what are those models of scale are key to success .
For procurement, right TCO and most important automation at scale is vital here
