NBN Atlas production environment - AtlasOfLivingAustralia/documentation Wiki
The NBN Atlas is managed and developed by the National Biodiversity Network (NBN), a UK charity whose priority is to grow national commitment to sharing biological data and information. The NBN Atlas can be found here: https://nbnatlas.org/ and it is the base for three country hubs: NBN Atlas Isle of Man, NBN Atlas Scotland and NBN Atlas Wales.
The objectives of the NBN Atlas concern education, promotion of biodiversity and providing a trusted portal for UK biodiversity data.
NBN Atlas development
The NBN Trust employs one full-time developer to manage, support and develop the NBN Atlas and country hubs.
NBN Atlas architecture
The NBN Atlas uses the following user-facing ALA components:
- bie (hub specific)
- biocache-hubs (hub specific)
- regions (hub specific)
- spatial-portal (hub specific)
These are supported by the following components which are shared among all hubs:
(Not so) current production environment diagram:
The NBN Atlas is currently running on AWS EC2 and Microsoft Azure and comprises more than 40 virtual machine instances. The Cassandra biocache occurrence database is sharded across 4 servers, as is the main biocache SOLR index. The hub-specific front-end components are hosted on EC2 t2.micro instances, except for the spatial portals which are t2.medium instances. Other components (e.g. bie-index, layers-service) require larger servers.
NBN Atlas species dictionary
The NBN Atlas uses the UK Species Inventory as the species dictionary for the name indexer.
