Overview
ArchivesSpace is an open-source archival information management application for managing archives, manuscripts, and digital objects, and providing web access.
I had the opportunity to set up ArchivesSpace on Amazon Lightsail, so this is a memo of the process.
Installation instructions are described on the following page.
https://archivesspace.github.io/tech-docs/readme_implement.html
Instance
I selected Ubuntu 20.04 LTS.

The documentation states the following, but since performance was sluggish with 2GB of memory, I selected 4GB.
At least 1024 MB RAM allocated to the application; at least 2 GB for optimal performance.

cd /home/ubuntu/
sudo apt-get -y update

quit;
cd /home/ubuntu/archivesspace
vi config/config.rb

cd /home/ubuntu/archivesspace/
scripts/setup-database.sh
Starting
Start ArchivesSpace with the following command:
cd /home/ubuntu/archivesspace/
./archivesspace.sh
Networking
Configure the firewall in the Amazon Lightsail management console. Open ports 8080-8082 and 8089-8090.

Summary
You can confirm ArchivesSpace is running on port 8080 as shown below.

I hope this serves as a helpful reference for setting up ArchivesSpace.
