Hardware requirements. Before the advent of large-scare services, an application might just exposes or references remote service by using RMI or Hessian, the call is done by configuring service URL, and load balance is done through hardwares, like F5. However, the size of the cluster and the data that we used are large enough to make conclusions about physical data modeling. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly available service on top of a cluster of computers, each of which may be prone to failures. However, I would like to get advantage of using HBase, HDFS, Impala, YARN, ZooKeeper, Spark.
