Summary
In this chapter, you learned how to deploy and manage key big data technologies such as Apache Spark, Apache Airflow, and Apache Kafka on Kubernetes. Deploying these tools on Kubernetes provides several benefits, including simplified operations, better resource utilization, scaling, high availability, and unified cluster management.
You started by deploying the Spark operator on Kubernetes and running a Spark application to process data from Amazon S3. This allows you to leverage Kubernetes for running Spark jobs in a cloud-native way, taking advantage of dynamic resource allocation and scaling.
Next, you deployed Apache Airflow on Kubernetes using the official Helm chart. You configured Airflow to run with the Kubernetes executor, enabling it to dynamically launch tasks on Kubernetes. You also set up remote logging to Amazon S3 for easier monitoring and debugging. Running Airflow on Kubernetes improves reliability, scalability, and resource utilization for orchestrating...
