Question
What does the System Orchestrator role in the NIST Big Data reference architecture primarily focus on?
A. Storing data in distributed systems
B. Managing workflows and operations across roles
C. Visualizing analytical outcomes
D. Designing predictive models
Answer
B. Managing workflows and operations across roles
Explanation
The System Orchestrator is a critical role within the NIST Big Data Reference Architecture (NBDRA). It acts as the central command center responsible for managing and coordinating the various components of a Big Data system. Its primary focus is on ensuring that all elements of the architecture—such as data providers, application providers, framework providers, and data consumers—work together seamlessly to achieve the system’s objectives. Below is a detailed breakdown of its responsibilities:
Core Responsibilities of the System Orchestrator
Workflow Management
The System Orchestrator defines and integrates data application activities into operational workflows. It ensures that these workflows are executed efficiently by coordinating interactions between different roles in the architecture.
Orchestration of Operations
It configures, deploys, and manages workloads across physical or virtual resources. This includes assigning tasks to specific nodes and monitoring their execution to meet performance and quality-of-service requirements.
Integration Across Roles
The orchestrator links together multiple applications, services, and components within the Big Data ecosystem. It facilitates interoperability by leveraging standardized interfaces and automation tools46.
System Monitoring and Adaptation
Through the Management Fabric, it monitors system performance and dynamically adjusts resources to handle changes in data volume or user demand. This ensures that operational goals are consistently met.
Policy and Governance Oversight
The System Orchestrator establishes policies, governance frameworks, and business requirements for the system, ensuring compliance with organizational objectives.
Why Other Options Are Incorrect
A. Storing data in distributed systems: This is primarily a responsibility of the Big Data Framework Provider, which manages infrastructure like storage and processing platforms.
C. Visualizing analytical outcomes: Visualization is handled by the Big Data Application Provider or Data Consumer roles, which focus on presenting insights derived from analytics.
D. Designing predictive models: This task falls under the domain of data scientists or analytics teams working within the Big Data Application Provider role.
In summary, the System Orchestrator plays a pivotal role in managing workflows and operations across all roles in a Big Data system, ensuring smooth coordination and execution of tasks while meeting organizational goals.
