Apache Mesos
Apache Mesos is an open-source cluster manager that provides efficient resource isolation and sharing across distributed applications or frameworks. It abstracts CPU, memory, storage, and other compute resources away from machines (physical or virtual), enabling fault-tolerant and elastic distributed systems. It acts as a kernel for data centers, allowing multiple frameworks like Hadoop, Spark, and Kafka to run on the same cluster.
Developers should learn Apache Mesos when building or managing large-scale, heterogeneous distributed systems that require high resource utilization and multi-framework support, such as in data centers or cloud environments. It is particularly useful for organizations running mixed workloads (e.g., batch processing and real-time analytics) on shared infrastructure, as it simplifies cluster management and improves efficiency through fine-grained resource allocation.
