#NoOps

Serverless computing or FaaS doesn't mean No Ops completely. Definitely, there is no system administration required to provision and manage infrastructure to run your applications. However, there are still some aspects of operations (Ops) involved in making sure your application is running the way it is supposed to run. You need to monitor your application using the monitoring data that FaaS offerings provide and ensure that they are running optimally. 

Ops doesn't just mean system administration. It also includes monitoring, deploying, securing, and production debugging.  With serverless apps, you still have to do all these and, in some cases, it may be harder to do Ops for serverless applications as the tool set is relatively new.
