Elastic Apache Mesos vs Gardener: What are the differences?
Elastic Apache Mesos: Automated creation of Apache Mesos clusters on Amazon EC2. Elastic Apache Mesos is a web service that automates the creation of Apache Mesos clusters on Amazon Elastic Compute Cloud (EC2). It provisions EC2 instances, installs dependencies including Apache ZooKeeper and HDFS, and delivers you a cluster with all the services running; Gardener: Manage Kubernetes clusters across multiple cloud providers. Many Open Source tools exist which help in creating and updating single Kubernetes clusters. However, the more clusters you need the harder it becomes to operate, monitor, manage and keep all of them alive and up-to-date. And that is exactly what project Gardener focuses on.
Elastic Apache Mesos and Gardener belong to "Cluster Management" category of the tech stack.
