Standard DevOps principles and tooling are used to allow for increased feature velocity as well as consistent deployments.Improved business outcomes: Speed, scale, and agility lead to increased revenue.Efficiency: Reusable services across teams and business units translate into lower OpEx cost for developer and customer.Flexibility: Strong infrastructure offers allow one to focus on app layers, where they create value/differentiation versus recreating common infrastructure.Speed: Lego approach to app creation shortens time to market and lets customer control pace of innovation.Consistent lifecycle management across containersĬloud Native customer benefits are depicted in the figure below.Continuous deployment and automation principles.Built-in microservice discovery mechanisms.Managed by Kubernetes-style orchestration.Developed using microservices architecture (that is, 12-factor apps).Cloud-native applications in general have these characteristics:

However, there are limitations in that VNFs upgrades are slow, restarts take a long time, CLI is still the main interface, software was typically a lift and shift operation, hypervisors such as OpenStack were hard to install, there was little elasticity, and scaling was problematic.Ĭloud-native applications address these limitations. Virtualization, when done properly, offered software models with increased flexibility with hardware dependencies eliminated. Virtualization and VNFs helped us in getting started in moving toward cloud-native applications. CNFs cover all branches of the service provider market, including cable, mobile, video, security, and network infrastructure. These CNFs, when running inside telecommunications premises, form a private cloud, and the same public cloud principles can be effectively used. This new technology has been selected by Cisco and others in the industry to develop next-generation Virtual Network Functions (VNFs) called Cloud-Native Network Functions (CNFs). Cloud-native principles and technology have proven to be an effective acceleration technology in building and continuously operating the largest clouds in the world.
