ALA production environment - AtlasOfLivingAustralia/documentation GitHub Wiki

Introduction

The Atlas of Living Australia has been running since 2008, with its first system going live in 2010. The key stakeholders for the Atlas are the zoological collections and herbaria of Australia. The Atlas is a single infrastructure that supports a number of front end (and separately branded) portals.

Architecture

This is a previous illustration of the production environment for ALA for a subset of the ALA components. The main differences are that the hosts have changed, and there is now use of AWS load balancers and AWS virtual machines, and there are near future changes to switch Cassandra to a cluster version rather than a single node:

Mains local points to this portal

• The ALA deployment is using a clustered deployment of Cassandra 3 and SOLR.
• ALA is currently using Amazon EC2 for its deployment, with some services running on CSIRO virtual machines
• ALA uses some load balancing for biocache web services
