BL0-220: Nokia Bell Labs Distributed Cloud Networks

It is not possible to run a cloud solution in a Single Node.A cloud solution requires a minimum of three nodes to provide high availability, scalability, and fault tolerance1.A Single Node is a standalone server that does not have any redundancy or load balancing features2. A Single Node can be used for testing or development purposes, but not for production or deployment of cloud applications.

Habana and EyeQ are two examples of AI hardware solutions that are designed to accelerate deep learning and computer vision applications.Habana is a company that produces AI processors for both training and inference workloads1.EyeQ is a family of system-on-chips (SoCs) developed by Mobileye for advanced driver-assistance systems (ADAS) and autonomous driving2. DataLake and Sparks are not AI hardware solutions.DataLake is a term that refers to a large-scale data storage architecture that can store structured, semi-structured, and unstructured data from various sources3.Sparks is a misspelling of Spark, which is an open-source distributed computing framework for large-scale data processing and machine learning4.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: AI/ML in Cloud Networks, Section 4.2: AI Hardware2: Nokia Bell Labs Distributed Cloud Networks, Unit 4: AI/ML in Cloud Networks, Section 4.2: AI Hardware3: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.4: Cloud Storage4: Nokia Bell Labs Distributed Cloud Networks, Unit 4: AI/ML in Cloud Networks, Section 4.3: AI Software

The properties related to a public cloud arefor users, there is no cloud infrastructure operationandeasy scaling.A public cloud is a cloud service that is offered by a third-party provider over the public internet, and is available to anyone who wants to use or purchase it1.Users of public cloud do not need to operate or maintain the cloud infrastructure, as it is the responsibility of the cloud provider2.Public cloud also offers easy scaling, as users can quickly and dynamically provision or release resources according to their needs2.Public cloud is suitable for applications that have unpredictable or variable demand, or that do not require a high level of security or customization3.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.1: Cloud Types2:Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.1: Cloud Computing3:Nokia and DISH to deploy first 5G standalone core network in the public cloud with AWS, Press Release

The 5G Core control plane is responsible for managing the network functions, services, and resources, such as authentication, authorization, session management, policy control, mobility management, etc.1.The 5G Core control plane can be deployed in a distributed cloud architecture, which consists of different cloud layers that have different characteristics and roles2.The Metro Edge Cloud is a cloud layer that is located near the access network, and provides low latency, high bandwidth, and local processing for the control plane functions3.The Core/Central Cloud is a cloud layer that is located in the core network, and provides high availability, scalability, and security for the control plane functions4.The distributed cloud architecture enables the 5G Core control plane to optimize the network performance, efficiency, and flexibility, and to support various use cases and applications.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.2: Cloud Architecture2:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Distributed Cloud3:Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.2: Cloud Resource Planning for Distributed Cloud4:Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.3: Cloud Resource Planning for Central Cloud :Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.1: Distributed Cloud Services Automation

On-premise Edge Cloud and Metro Edge Cloud are the cloud deployments that provide the lowest latency.Latency is the time it takes for data to travel from the source to the destination1.On-premise Edge Cloud is a cloud deployment that is located within the premises of the end-user, such as a factory, a hospital, or a campus2.Metro Edge Cloud is a cloud deployment that is located within the same metropolitan area as the end-user, such as a city or a suburb3.Both On-premise Edge Cloud and Metro Edge Cloud reduce the distance and the number of hops that data has to travel, resulting in lower latency and higher performance4. Far Edge Cloud and Central Cloud are not the cloud deployments that provide the lowest latency.Far Edge Cloud is a cloud deployment that is located at the edge of the operator's network, such as a regional data center or a base station3.Central Cloud is a cloud deployment that is located at the core of the operator's network, such as a national data center or a cloud provider3.Both Far Edge Cloud and Central Cloud increase the distance and the number of hops that data has to travel, resulting in higher latency and lower performance4.

Hyperscale computing relies on scalable server architecture.This is true because hyperscale computing is a type of cloud computing that aims to provide massive scalability, performance, and efficiency for large-scale applications and data processing1.Hyperscale computing requires a scalable server architecture that can support thousands or millions of servers that are interconnected by high-speed networks2.Scalable server architecture enables hyperscale computing to handle increasing workloads, optimize resource utilization, and reduce operational costs3.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.1: Industry Trends in Data Center Hardware2: How Nokia Bell Labs' new serverless computing design will take cloud computing to the next level43: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks1
