Study Notes

Virtualization and Big Data

  • Virtualization: a technology that enables multiple virtual machines (VMs) to run on a single physical machine, maximizing resource utilization and scalability.
  • Benefits in Big Data:
    • Enables multiple big data nodes to run on a single physical machine, improving resource utilization and reducing hardware costs.
    • Allows for easy scalability and deployment of big data clusters.

Cloud and Big Data

  • Cloud Computing: a model for delivering computing services over the internet, providing on-demand access to a shared pool of resources.
  • Benefits in Big Data:
    • Enables scalable and on-demand access to computing resources, ideal for big data processing and analytics.
    • Reduces costs associated with hardware, maintenance, and personnel.
    • Supports collaboration and data sharing across organizations and locations.

Big Data Technology Components

Data Ingestion

  • Data Ingestion: the process of collecting and transporting data from various sources to a centralized location for processing and analysis.
  • Components:
    • Data Ingestion Tools: Flume, Sqoop, Kafka, and NiFi.
    • Data Transport: batch or real-time data transport from sources to targets.

Data Storage

  • Distributed File Systems: store and manage large amounts of data across a cluster of machines.
  • Components:
    • HDFS (Hadoop Distributed File System): a widely used distributed file system for big data storage.
    • NoSQL Databases: handle large amounts of unstructured or semi-structured data.

Data Processing

  • Data Processing: the process of transforming and analyzing data to extract insights and knowledge.
  • Components:
    • MapReduce: a programming model for processing large datasets in parallel across a cluster of nodes.
    • Spark: an in-memory processing engine for large-scale data processing.

Data Analytics

  • Data Analytics: the process of extracting insights and knowledge from processed data.
  • Components:
    • Data Warehousing: a centralized repository for storing and managing data for analytics.
    • Business Intelligence Tools: provide data visualization, reporting, and analytics capabilities.

Understand the basics of big data technology, including virtualization, cloud computing, data ingestion, storage, processing, and analytics. Learn about the components and benefits of each technology.
