Jelastic Cluster Overview
Cluster is a group of servers and other resources, that act like a single system by providing the ability to develop, debug, deploy, test, run and maintain hosted applications. Jelastic Cluster includes Hardware Nodes (or VMs) and a Cluster Orchestrator.
Cluster Orchestrator (Infrastructure node) is a set of internal components for managing resources, processing requests, analyzing users' behaviors and supporting Jelastic system maintenance.
Hardware nodes are physical servers (or VMs), which store the isolated virtual containers, provisioned for users' environments.
Jelastic environment is a collection of isolated virtual containers, that provides all the facilities necessary for a particular application.
Node is a virtual isolated container, provisioned for the environment and stored on a particular hardware node.
General Cluster Overview
Jelastic PaaS is an isolated cluster with a group of servers and other resources that act like a single system for providing the ability to develop, debug, deploy, test, run and maintain hosted applications.
Jelastic Cluster includes Hardware Nodes where virtual isolated containers provisioned for environment are located and Cluster Orchestrator (Infrastructure Node) for internal components processing.
