GLU.Engine

The only 3rd party product used by GLU are 

– Java Version 1.8 

– A server to host the Java virtual machine (Docker/VM/server)

The GLU.Engine Server hosts the executable generated by the GLU.Console to provide integration. It takes the form of a .JAR file (i.e. Springboot Container). Each ‘Application’ equates to one GLU.Engine and each GLU.Engine can be deployed on its own Hardware as outlined below and depending on port values. 

This Hardware recommendation is provided as a baseline specification to be considered in parallel with the performance expectations. 

If there is an expectation of high or system performance, CPU & memory should be increased. 

To provide scale a GLU.engines can be scaled horizontally utilising a load balancer as part of the solution or a GLU.Engine setup as a Decision Maker to send transactions to a set of GLU.Engines running parallel. Please contact GLU support for more details on setting up these architectures.

Deploying and running a GLU.Engine

A GLU.Engine can be deploy in the following ways 

• A GLU.Engine deployed on a server.
• A GLU.Engine deployed in docker container manager such as SwarmPit, Kubernetes docker desktop.

The diagram below describes how the GLU.Engines can be set up with 3rd party monitoring and logging analytic capabilities as well as an internal web page generated to show swagger definition for the APIs in the GLU.Engine. 

GLU recommends the use of Grafana on a separate server to monitor and provide alerts on data coming from the data produced by the GLU.Engine. 

Prometheus and node exporter can be used on the GLU.Engine server to gather and send the monitoring data to Grafana. 

• Node Exporter : nodeexporter.json
• Prometheus : https://prometheus.io/docs/visualization/grafana/
• Grafana : https://grafana.com

For Logging GLU recommends Elastic Search and provides a configuration of filebeats to facilitate either pushing the GLU.Engine logs to ElasticSearch or to Logstash. 

• filebeats : https://www.elastic.co/guide/en/beats/libbeat/7.8/index.html
• Logstash : https://www.elastic.co/guide/en/logstash/current/index.html
• ElasticSearch : https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html
• Kibana : https://www.elastic.co/guide/en/kibana/current/index.html

Direct to ElasticSearch
