What are the advantages of using Apache spark over Hadoop?

Apache Spark is potentially 100 times faster than Hadoop MapReduce. Apache Spark utilizes RAM and isn’t tied to Hadoop’s two-stage paradigm. Apache Spark works well for smaller data sets that can all fit into a server’s RAM. Hadoop is more cost-effective for processing massive data sets.

What is Apache spark in layman’s terms?

Apache Spark is a powerful open-source processing engine built around speed, ease of use, and sophisticated analytics, with APIs in Java, Scala, Python, R, and SQL. Spark runs programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.

Does AWS use Spark?

Apache Spark is a unified analytics engine for large scale, distributed data processing. Typically, businesses with Spark-based workloads on AWS use their own stack built on top of Amazon Elastic Compute Cloud (Amazon EC2), or Amazon EMR to run and scale Apache Spark, Hive, Presto, and other big data frameworks.
