Build a Flink Cluster for Computations Over Data Streams

This lab uses Alibaba Cloud Elastic Compute Service (ECS) resources. This lab describes how to build a Flink cluster and how to run stream tasks. Apache Flink is a framework and distributed processing engine for stateful computations over *unbounded and bounded* data streams. Flink is designed to run in *all common cluster environments*, perform computations at *in-memory speed* and at *any scale*.
