Overview

The Fusion Edge Server is designed to be deployed across multiple servers and positioned behind a load balancer to achieve high availability. Strategies can be put in place with regards to rolling deploys for software upgrade, and different techniques can be used to support data and metadata updates.

For simple deployments, including testing, installing the Fusion Edge server can be a very fast, painless experience. Simply install Apache Tomcat, and Java, and put the Fusion Edge Server application (war file) into tomcat/webapps and launch Tomcat.

This guide provides information on how to deploy and load Fusion Edge Server with a single Tomcat instance.

Quick Start with Apache Tomcat

Deploy Application and Launch Web Server

The Fusion Edge Server consists of a single .war file called FusionEdgeServer.war.

  1. Copy FusionEdgeServer.war into the directory: <TOMCAT_HOME>/webapps
  2. Start the Tomcat Server
  3. Check the Tomcat <TOMCAT_HOME>/logs to ensure there are no errors in the log files

During the Tomcat start-up process, the war file will be unpacked into a directory of the same name, for example:

<TOMCAT_HOME>/webapps/FusionEdgeServer

On successful launch the Fusion Edge Server product information service can be queried from the following URL:

http://[server]:[port]/FusionEdgeServer/ws/fusion/info/product

The values for server and port must be replaced with the IP address and port number that the web application server is running on. For example, if the web browser is running on the same machine as the web application server and the Apache Tomcat has not had its default port settings modified, then the following address can be used:

http://localhost:8080/FusionEdgeServer

The Fusion Edge Server is now deployed and running in a web container, the URL will result in an empty (white page) - remeber the purpose of the FusionEdgeServer is to host a READ ONLY REST API to your SDMX Structural Metadata, Data, and Reference Metadata. The Fusion Edge server has no User Interface, so the white empty page is a good thing. The REST API of the Fusion Edge Server can be used to browse your content, which should be currently empty.

Deploy Content to the Fusion Edge Server

In order to deploy content to the Fusion Edge server, a single file named node.zip should be placed in the sweep Fusion Edge Server Directory.

The node.zip file is copied into the sweep folder, this folder is scanned by the Fusion Edge Server every few seconds, and when a new node.zip file is detected the Fusion Edge Server moves it into the processing directory while it builds the new environment. When the environment is built, the file is mored into the processed directory and all content will be queryable via the Fusion Edge Server's web services.

If the Tomcat server is shut down and relaunched, it will reload the environment from the processed folder as part of the startup process. The Tomcat server will only come into service once the environment is loaded.

Test Web Service

The structural metadata, data, and reference metadata held in the Fusion Edge Server is made available via SDMX compliant web services. The web service entry point for the Node is available at:

http(s)://[server]:[port]/FusionEdgeServer/ws/public/sdmxapi/rest

A test query can be issued, for example:

https://localhost:8080/FusionEdgeServer/ws/public/sdmxapi/rest/dataflow
