6. Apache Hadoop
Apache Hadoop is an open-source software framework designed for distributed storage and processing of large-scale datasets. It consists of two main components: the Hadoop Distributed File System (HDFS) and the MapReduce processing engine.
While HDFS is a distributed file system that allows data to be stored across multiple machines in a cluster, MapReduce is a programming model used for parallel processing and analysis of large datasets stored in Hadoop.
Apache Hadoop can scale horizontally by adding more machines to the cluster, allowing it to handle petabytes or even exabytes of data.
It can run on commodity hardware, which is relatively inexpensive compared to specialized hardware solutions.
With data replication in HDFS, if a node fails, data can be retrieved from other replicas. Similarly, if a computation fails, it can be automatically restarted on another node, ensuring job completion.
It handles structured, semi-structured, and unstructured data, allowing organizations to analyze diverse sources such as text, log files, social media, and sensor data.
7. Apache Spark
Apache Spark is an open-source distributed computing system designed for processing and analyzing large-scale data sets. It provides a high-level programming interface and a unified engine that enables users to perform various data processing tasks, including batch processing, real-time streaming, machine learning, and graph processing.
Known for its exceptional speed due to its in-memory computing capabilities, it can cache data in memory, allowing iterative and interactive data analysis tasks to be performed much faster than traditional disk-based systems.
Its distributed computing model enables it to scale horizontally by distributing data across multiple nodes in a cluster.
It provides a versatile programming model that supports multiple languages such as Scala, Java, Python, and R.
It provides built-in fault tolerance mechanisms, allowing it to recover from failures and continue processing without losing data.
Data Storage Integration
Spark integrates well with various data storage systems, including Hadoop Distributed File System (HDFS), Apache Cassandra, and Apache HBase.
It offers Spark SQL for querying structured data, MLlib for scalable machine learning, GraphX for graph processing, and Spark Streaming for real-time data processing.
SAS, or Statistical Analysis System, is a software suite used for advanced analytics, business intelligence, and data management. It offers a wide range of data analysis, statistical modeling, and data visualization tools.
