Basic Concepts

Tip: The detailed Concepts & Terminology of the Jelastic PaaS can be viewed in the dedicated document.
A cluster is a group of servers and other resources that act as a single system for providing the ability to install, run, and maintain hosted applications. A Jelastic Cluster includes Hosts and a Cluster Orchestrator.

Cluster Orchestrator is a set of internal components for managing, processing, analyzing, and supporting the Jelastic PaaS.

Hosts are the physical servers which store all the isolated containers installed by end-users.

An environment is a collection of isolated nodes (software stacks), which are required for running particular application services.

Node (Container) is an isolated virtual instance, which provision particular software stack.

IP Pool contains a list of the internal (for usage inside the сluster only) and external (both IPv4 and IPv6, for access from anywhere over the Internet) IP addresses, which are available on the platform.

Migration is the operation of navigating containers between different hosts without interruption of the running processes. It is required to locate nodes on hosts during the creation and to balance platform load during the lifecycle.
