One of the unique values for telecom multicloud solutions is that it should scale to 100,000’s of sites in an automated manner. Automation must be enabled on each layer and delivered in a distributed manner. For automation to work we should align the solution with a telco’s architecture which is distributed across Core, Regional and RAN data centers. See Figure 8.
At the heart of Dell Telecom MultiCloud Foundation are NDC components. These components include all management and automation software, including standard API interfaces to integrate with customer orchestration and inventory systems. It includes:
Dell BMO and its API plug-in are vital parts of the solution as they enable full automation of infrastructure discovery and LCM, and provide seamless integration to the cloud platform. This solution is unique for telcos accelerating fully distributed cloud deployments that include tens of thousands of sites. BMO is a vendor-agnostic orchestrator, so it can be used to manage not only Dell infrastructure but also any third-party infrastructure using standard APIs.
The Wind River Studio Conductor is deployed in the National Data Center (NDC) as an orchestrator and infrastructure automation manager. It integrates with Dell BMO to provide complete end-to-end automation for the full hardware and software stack. Also, it provides a centralized point of control for managing and automating application deployment in an environment that is large-scale and distributed.
Studio Conductor receives information from Bare Metal Orchestrator as new cell sites come online. Studio Conductor instructs the system controller (CaaS manager) to install, bootstrap, and deploy Studio Cloud Platform at the cell sites. It supports Topology and Orchestration Specification for Cloud Application (TOSCA) based blueprint modeling. Blueprints are policies that enable orchestration modeling. Studio Conductor uses blueprints to map services to all distributed clouds and determine the right place to deploy. It also includes integrated secret storage to securely store password keys internally, reducing threat opportunities. Studio Conductor can adapt and integrate with existing orchestration solutions. The plug-in architecture allows it to accommodate new and old technologies, so it can easily be extended to accommodate evolving requirements.
The Dell Telecom MultiCloud Foundation solution delivers full automation by distributing cloud deployment with distributed site controller to be deployed in the (Regional Data Center (RDC) sites. The solution provides orchestration and synchronization services for up to 1000 distributed subclouds or cell sites. The solution is responsible for cell sites management and deployment in a scalable manner if customer plan to roll out thousands of sites. The RDC can scale out to give you this capability as well. In the RDC, the solution deploys three R750 servers that include:
Site controllers include Wind River Studio Cloud Platform, Wind River Studio Conductor, and Wind River Studio Analytics factory installed. Wind River Studio Analytics is an integrated data collection, monitoring, analysis, and reporting tool used to optimize distributed network operations. Studio Analytics solves a unique use case for the distributed Edge. It provides visibility and operational insights into the Studio Cloud Platform from a Kubernetes and application workload perspective.
Studio Analytics has an integrated alerting system with the ability to integrate with several third-party monitoring systems. Studio Analytics uses technology from Elastic.co as a foundation to take data reliably and securely from any source and format, and then search, analyze, and visualize it in real time. Studio Analytics also uses the Kibana product from Elastic as an open user interface to visually display the data in a dashboard.
The cell site that hosts the containerized RAN applications includes XR11 servers with the Wind River cloud platform’s Kubernetes cluster (leader and worker nodes) on every cell site. The site controller in the RDC manages the cloud deployment, which is orchestrated and operated through the central clouds that are deployed in the NDCs.
The federated and automated cloud infrastructure is shown in Figure 9.
