Explanation

Infrastructure as a Service (IaaS) provides on-demand virtual computing resources that can be dynamically created and destroyed. According to cloud computing documentation, IaaS instances are designed to be ephemeral, allowing users to launch instances when needed and terminate them when no longer required. This makes statement A correct. Additionally, IaaS platforms expose APIs and service interfaces that enable full automation of instance lifecycle management. Instances can be created, modified, and deleted programmatically using scripts, orchestration tools, or cloud SDKs, making statement B correct.
