Standard clusters are ideal for processing large amounts of data with Apache Spark. We recommand to use standard cluster for a single user because it meant to be handle less load compare to high con cluster.
High Concurrency clusters are ideal for groups of users who need to share resources or run ad-hoc jobs. Administrators usually create High Concurrency clusters.The key benefits of High Concurrency clusters are that they provide Apache Spark-native fine-grained sharing for maximum resource utilization and minimum query latencies.
