 Scalability and Openness are the focus of an agile data center. Scalability refers to the ability of a data center to adapt to changing demands and workloads by adding or removing resources dynamically. Openness refers to the use of open standards and interfaces that enable interoperability and integration of different technologies and vendors in a data center. An agile data center can provide flexible, efficient, and cost-effective services to customers and applications, while reducing operational complexity and overhead. Fixed Architecture and Closed Cloud System are not the focus of an agile data center. Fixed Architecture means a rigid and predefined structure of a data center that cannot be easily modified or customized. Closed Cloud System means a proprietary and isolated cloud platform that does not support compatibility or collaboration with other cloud platforms or services. A fixed architecture and a closed cloud system can limit the performance, functionality, and innovation of a data center, and increase the dependency and lock-in of customers and applications. References: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Cloud Agility.

Containers as a Service (CaaS) is the same as the E2E Orchestrator for VMs for containers. CaaS is a cloud service model that allows users to deploy and manage containerized applications on a cloud platform. CaaS provides the necessary infrastructure, orchestration, networking, and security for running containers. The E2E Orchestrator for VMs is a Nokia solution that provides similar capabilities for virtual machines (VMs). The E2E Orchestrator for VMs enables the creation, deployment, and management of VMs on a distributed cloud platform. It also supports network slicing, security, and automation features.

Network Service Orchestration is the process of managing the lifecycle of network services across multiple domains and technologies. It automates NFV service bydeploying, configuring, and scaling virtual network functions (VNFs) on demand. It is part of the 5G key enablers because it supports the dynamic and flexible provisioning of network slices and edge cloud applications. It does not increase operational complexity, but rather simplifies and optimizes it by using AI/ML and closed loop automation.

 Security is crucial for data centers and their users because data centers store, process, and transmit large amounts of sensitive and valuable data for various organizations and individuals. Data centers face various security threats such as cyberattacks, natural disasters, human errors, power outages, etc. that can compromise the confidentiality, integrity, and availability of the data and the services1. Therefore, data centers need to implement various security measures such as encryption, authentication, authorization, backup, firewall, antivirus, physical security, etc. to protect the data and the users from unauthorized access, data loss, data corruption, service disruption, etc2. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.3: Cloud Networking Features 2: Data Center Security: What You Need to Know
