I always recommended or alerted for 5G aspirant.
1. 5G is about End to End vision
2. Though 5G arhitecture is flat but it is complex and convoluted.
3. For jumping into 5G create your team of consultants.
This is corroborated here below too....
Found a nice read from Ericsson, good to go through.....
5G is expected to deliver unprecedented performance in terms of transmission capacity and packet transit delays, enabling new applications and services in areas as diverse as the Internet of Things, augmented reality and the Industrial Internet. To dynamically define the features supported by the infrastructure and the ways in which these features are managed.
DevOps can be used to optimize a software delivery cycle, including everything from feature development to operations across disciplines (development, customer engagement and operations) through to continuous delivery (CD) practices. Focusing on automation and lean management practices enables flow control and transparency across the cycle. The organizational and administrative interfaces between the different actors within the 5G ecosystem must be easy to traverse, with appropriate software to secure continuous automation flows.
In a 5G context, the word software refers to both the actual code of virtual network functions (VNFs) and models describing the infrastructure and execution environments hosting this code. While software flows clockwise through the cycle, each stage provides feedback to the previous one (counterclockwise) to allow for software quality improvement and process optimization.
The architecture plays a significant role in building, deploying and operating complex systems. In NFV, it describes how high-level functions typically developed by different teams or open source projects can be interconnected and packaged together to provide a service. Capabilities defined by the NFV MANO architecture  allow for dynamic configuration of parameters, dimensioning and scaling a service to reach a wanted set of performance indicators or policies.
Experiences and insights from implementing the automation, optimizing the software delivery cycle and operations are then used to drive the architecture management and improve development and testing of individual functions in a DevOps deployment.
DevOps and continuous everything
DevOps is an interactive approach to product management, development, deployment and operation that stresses communication, collaboration, integration and automation. Working together with the customer every step of the way, the DevOps approach begins with requirement setting and continues through development and operations.
Continuous integration – Automated process of secure and frequent integration of source code into source baselines, and binaries into system baselines.
Continuous delivery – Automated process of secure and frequent internal provisioning of ready-to-install software product versions of integrated software.
Continuous release – Automated process of secure and frequent provisioning of delivered software product to external customers and clients.
Continuous deployment – Automated process of secure and frequent production, testing and/or monitoring, and deployment of software products to customer equipment in a live environment.

The stringent requirements of 5G networks are driving the need for further adaptation of existing DevOps practices and toolchains to the telecom industry. Our work with the open source and academic communities demonstrates how to address the 5G challenges related to the evolution of classic telecom fulfillment and assurance processes toward DevOps-powered cycles. Doing so requires an architecture that supports automated deployment and operations, using powerful description languages tailored to different system dimensions that can capture constraints and feature specifications. Transparency of state changes and transitions throughout the architecture enables efficient operations. Our experience in the OPNFV community shows that CD practices including feedback loops throughout the technology stack and across organizations are key to a successful DevOps implementation.
