Cisco Ultra Cloud Core At-a-Glance

Cisco Ultra Cloud Core provides a common execution environment and a Continuous-Integration-and-Continuous Delivery (CIDC) framework for Cisco’s container-based 5G applications.

Using the Cisco® Ultra Cloud Core, 5G applications are enabled with:

  • Advanced analytics and advanced infrastructure health checks
  • Simplified and low-risk methods to introduce new 5G services, new configurations, and upgrades
  • Automated deployment and automated testing as part of a CI/ CD workflow
  • Consistent technology and software components across all Cisco 5G applications


Increased efficiencies

Cisco’s cloud-native packet core (cnCore) is the latest generation of the virtual packet core. Launched in 2016, it delivers on the promise of 5G with high throughput at the edge and ultra-low latency required for advanced use cases in video, Augmented Reality and Virtual Reality (AR/VR), Artificial Intelligence (AI), and robotics. Cisco Ultra is the control point in the 5G architecture where the radio network is turned into useful IP packets to meet the needs of both the consumer and Enterprise markets.

The Cisco Ultra Cloud Core provides an intelligent service mesh that connects all services in the platform. This service mesh allows granular control of traffic flows within the Cisco Ultra Cloud Core based on message attributes or subscriber details. New or upgraded services can run concurrently in the platform alongside existing services, and the service mesh controls which messages are directed to the new service. Per-service telemetry is available to compare and evaluate the success of the new service. As a result, rollouts and upgrades are low risk and can be entirely automated—removing the human element.


Benefits for the service providers

  • Offers a cloud-native, multi-tenant software platform for creation of new use cases tailored for enterprise
  • Includes operator-specific differentiation
  • Provides an open API to offer enterprises a different set of capabilities for Networking as a Service (NaaS)
  • Enables greater operator control: time to market and feature differentiations
  • Minimum or no impact to standard functions
  • Protection of Mobile Network Operator (MNO) functions by verification of changes by enterprises
  • Creates valuable information by filtering and processing generic data
  • Takes advantage of existing 4G as well as future 5G functions
  • Includes charging and auditing functions for monetization and support

Why you want a cloud-native platform

Cisco’s cloud-native Mobile Core provides benefits in three key areas:

  • CI/CD workflows. Implementation of services can be reduced to four minutes versus four hours, resulting in an 80 percent or greater improvement in OpEx. For example, VNFs are deployed 18 times faster with containers.
  • Micro-service architectures. Micro-services enable agility in the release of new features, and when combined with a CI/CD workflow, they can reduce availability of releases with new services in four days rather than four months, for a more than 90-percent improvement in time to market. For example, a cloud-native “canary” process can enable zero downtime for feature deployment, versus the 5-10 seconds per containers for a greater than 85-percent reduction in costs alone.
  • Performance. The efficiency of cloud-native technology means that performance of the user plane using Cisco’s Vector Packet Processing technology means that performance jumps from approximately 20 Gbps per server to approximately 400 Gbps per server, for a 20-times improvement.


  • Simplicity and automation
  • A cloud-native packet core provides for a new level of automation and simplicity with an API-driven approach to provision and operate Virtual Network Functions (VNF)
  • Performance and modularization - built for multi-cloud to run anywhere
