Building SaaS is just one part of the challenge. Operating a SaaS is another major challenge. We will need fleet-wide observability on what tenant-level activity is happening in the fleet including any operational issues, assistance with debugging active issues like metrics and logging, ability to hot patch tenants, rollout security fixes in <24 hours. In addition, we will need reliable monitoring, recovery mechanisms to common issues with full auditing of events on what happened. In case, things are not recoverable for any reason, we will need a reliable alerting mechanism so that you can stay ahead of your customers and address the issues quickly.
