Editor's Notes

  • Data Analytics: This layer includes high-level analytical applications similar to R or Tableau delivered over a cloud computing platform which can be used to analyze the underlying data. Users can access these technologies in this layer through a web interface where they can create queries and define reports that will be based on the underlying data in the storage layer. Technologies in the data analytics layer abstract complexities of the
    underlying BDaaS stack and enable better utilization of data within the system. The web interface of those technologies may have wizards and graphical tools that enable the user to perform complex statistical analysis.

    Data Management: In this layer, higher level applications such as Amazon Relational Database Service (RDS) and DynamoDB (see Chapter 6) are implemented to provide distributed data management and processing services. Technologies contained in this layer provide database management services over a cloud platform.

    Computation Layer: This layer is composed of technologies that provide computing services over a web platform. For example, using Amazon Elastic MapReduce (EMR), users can write programs to manipulate data and store the results in a cloud platform. This layer includes the processing framework as well as APIs and other programs to help the programs utilize it.

    Cloud Infrastructure: In this layer cloud platforms such as open stack or VMware ESX server provide the virtual cloud environment that forms the basis of the BDaaS stack.

    Data Infrastructure: This layer is composed of the actual data center hardware and the physical nodes of the system. Data centers are typically composed of thousands of servers connected to each other by a high-speed network line enabling transfer of data. The data centers also have routers, firewalls, and backup systems to insure protection against data loss.
