Monitoring & incident response
An outage becomes expensive when it is first noticed through a customer call. This category covers monitoring and response: availability checks from several networks, monitoring critical flows such as cart and checkout, certificate and domain expiry, error rates and response times, disk space and queues. We show how to set thresholds so alerts are taken seriously instead of drowning in noise, and what an on-call procedure with clear responsibilities looks like. Added to this are recovery plans: which backups exist, how long a restore actually takes, who informs customers and service providers. Post-incident review and root cause analysis are part of it as well. We also cover communication: which information customers and service providers need during an incident and who approves it.
