AWS Lambda was the first serverless application service built by AWS. When developers build an application, the next thing they need is a server provisioned for them with some specifications for CPU, memory, and disk at least. Now, the system administrators and DevOps engineers are tasked with ensuring the infrastructure that has been provisioned is enough to keep the application running. If for any reason more resources are needed, then the onus is on AWS to provide that infrastructure to avoid any downtime on the application running within the server that has been provisioned.

This has made operations teams grow larger because the more customers and users the company acquires for the application, the more engineers will need to be employed to manage the scale of the application, both from the development and operations perspective. It requires operations engineers that understand how to design and plan for an application...
