Summary and Quiz

Get a refresher on the Analytics section, and take a short quiz to test your knowledge.

We'll cover the following

In this lesson, we’ll summarize what we have learned about the analytics services provided by AWS. Also, we’ll test our knowledge through a quiz.

Summary

Here is a summary of key takeaways from the Analytics section:

  • AWS EMR: Amazon Elastic Map Reduce is a fully managed service that helps us process and analyze large amounts of data. It simplifies running big data frameworks like Hadoop and Spark on AWS for data processing and analysis. Each EMR cluster has a primary, task, and core node.

  • Amazon Redshift: It is a fully managed data warehousing service. It supports a multi-query engine with a massively parallel architecture, which allows us to perform complex queries on large amounts of data in less time. Each Redshift cluster consists of a leader node responsible for managing the queries and results and multiple compute nodes to perform parallel queries on the data.

  • AWS Glue: AWS Glue is a serverless data integration service facilitating easy discovery, preparation, movement, and integration of data from multiple sources, aiding analytics, machine learning, and application development. AWS Glue automates data discovery through a data crawler, organizes data on a data catalog, and creates ETL jobs to extract, transform, and load data.

  • AWS Lake Formation: AWS Lake Formation helps organize the data for easier analysis. It gathers data from various sources like databases and file storage into the data lake. It is built on AWS Glue and utilizes features like data catalog, crawlers, and jobs.

  • Amazon Athena: Amazon Athena is a serverless, interactive service that allows us to query data in Amazon S3 using standard SQL queries. Athena can work with various data formats stored in an S3 bucket, including CSV, JSON, ORC, Parquet, and more.

  • Amazon QuickSight: Through QuickSight, we can create interactive dashboards to visualize key data metrics and for ad-hoc analysis. It enables us to create customized interactive sheets and paginated reports, which can easily be shared to gain quick visual data insights. It also supports natural language queries using QuickSight Q.

  • AWS Kinesis: Amazon Kinesis provides a powerful and scalable platform for processing and analyzing real-time streaming data. It provides a suite of services, including:

    • Amazon Kinesis Data Streams that allows to ingest, buffer, and process large volumes of data continuously in real-time

    • Amazon Data Firehose to deliver real-time data streams to other AWS services for storage, transformation, or further analysis. It bridges the processing stage, often handled by Kinesis Data Streams, and the destination where we want the data to reside.

    • Amazon Kinesis Video Streams to securely capture, store, and analyze video streams from multiple sources.

    • Amazon Kinesis Data Analytics to process and analyze continuously streaming data using standard SQL. It allows us to create and run powerful SQL code against streaming sources for time series analytics, real-time dashboards, and custom metrics.

  • AWS MSK: Amazon Managed Streaming for Apache Kafka enables us to build and run applications to handle real-time data streams. Each MSK cluster consists of the following main components:

    • Topics: Topics aggregate and classify different types of data streams.

    • Producers and consumers: The data producers publish their data streams to these topics to be consumed by the consumers.

    • Broker nodes: The broker nodes connect the data producers, consumers, and topics and are responsible for receiving, managing, and forwarding data.

    • Zookeepers: Zookeepers are responsible for managing the coordination and state of the Kafka cluster. They maintain metadata about brokers, topics, partitions, and consumer groups, ensuring the overall stability and reliability of the Kafka cluster.

  • AWS Data Exchange: AWS Data Exchange is a marketplace for data. It allows data producers to upload their data for sale and data consumers to buy the data in an organized manner. It supports two main data exchange mechanisms: Data Grants and AWS Marketplace Data Products.

  • AWS Data Pipeline: AWS Data Pipeline helps us move and transform data across various sources. It provides a way to define data processing workflows (like a recipe) and schedule, monitor, and manage data pipelines efficiently. It offers features like pipeline definitions to specify data processing steps and task runners to execute tasks on provisioned resources.

  • Amazon OpenSearch: The OpenSearch service is a RESTful analytical engine that creates a cluster to process large amounts of data and allows us to interact with the cluster through an OpenSerch domain. It offers dashboards for visualization and data preppers to prepare data for ingestion.
