Considerations when hosting

Considerations when hosting the CHT

Some important questions to consider when setting up hosting for the CHT:

• Alerting - How will alerts be sent in the case of downtime or degraded service? While Watchdog can be set up to monitor CHT Core instances - which monitoring system will be used to alert on OS level warnings?
• Power failures and unplanned restarts - Will the server cleanly restart such that the CHT resumes service correctly?
• Backups - What happens to the CHT data if there’s a hard drive failure? Are there provisions for a 3-2-1 backup strategy? See the backup docs for more information.
• Disaster Recovery - What happens if there is a flood at the facility and on-site active and backup data are destroyed?
• Scale - What happens when the hardware deployed needs to be upgraded to increase capacity?
• Updates - CHT Core updates happen many times throughout the year - do you have a maintenance schedule for these and staff who are trained to do the upgrade?
• Renewals - Services such as TLS certificates and domains name registration expire periodically and will make the server inaccessible - do you have a schedule for monitoring and renewing these in a timely manner?
• Security - While the TLS certificate will protect data on the Internet, is the server hard drive encrypted in the event of property theft? Is there a sufficient policy in place when generating and handling passwords for CHWs? Have you considered Token Login to further reduce risk?
• Privacy - The CHT inherently carries sensitive patient medical information in the database. Are there sufficient measures in place to protect this sensitive data?
