Nest Seekers web and background processing servers have been on Rackspace for many years, but now it's time to move. AWS offers Docker hosting and managed database services that will reduce costs, improve scalability and resilience, while decreasing maintenance and complexity for future developers.
Previous deployments have been done manually, with Puppet and lately with Ansible. Kubernetes still requires substantial expertise (and full-time devops). Terraform was chosen for its clean declarative syntax and large library of reusable modules.
AWS offers high-availability managed databases with continual backups, built in monitoring, and automated software patches. In case of disaster, data can be quickly restored to any point in time.
The new infrastructure reduces configuration complexity while increasing security and scalability.
