Finally, serverless code requires very little active management. An application running on a shared server will usually require a significant amount of monitoring and management, for both the server itself and its resource allocation at any given moment. Containerized code, or code running on virtual machines, is better, but still requires either container management software or a person to monitor the usage and then scale down or scale up appropriately, even if the server itself no longer requires active management. Serverless code has no server visible to the developer and will scale according to demand, meaning that it requires monitoring only for exceptions or security issues, with no real active management to keep a normal service running.
