The Commons runs on Amazon Web Services (AWS) infrastructure, using EC2 instances running Ubuntu Linux. Our databases run on RDS, and we use various other AWS services including S3, VPC, EBS backup, OpenSearch, CloudFront, CloudWatch, and Route 53. We have development, staging, and production servers running on AWS.
Our WordPress servers run Ubuntu Linux with the NGINX web server, PHP-FPM, and Amazon RDS. All instances and databases are backed-up regularly.
The CORE repository is hosted on servers managed by the Michigan State University Libraries.
