The adoption of IaaS and cloud computing pushed innovation and churned out a paradigm called PaaS, or Platform as a Service. Leveraging the foundation set by IaaS, cloud providers started to abstract away services like load balancing, continuous integration and deployment, edge and traffic engineering, HA, and failover, into opinionated turnkey offerings. PaaS further reduced the responsibility spectrum of a company producing code to the following responsibilities:
- Architecting and designing systems
- Authoring code
- Maintenance and patch management
