Final answer:
In an IaaS environment, the customer has additional responsibilities including application deployment, network configuration, and data backup.
Step-by-step explanation:
In an IaaS (Infrastructure as a Service) environment, there are additional responsibilities that lie with the customer apart from the three core ones. These additional responsibilities include:
- Application Deployment: The customer is responsible for deploying and managing their own applications on the infrastructure provided by the IaaS provider.
- Network Configuration: The customer needs to configure and manage their networking setup, including configuring virtual networks, firewalls, and load balancers.
- Data Backup: The customer is responsible for backing up their data hosted on the IaaS infrastructure to ensure data protection and availability.
These responsibilities are crucial for the customer to effectively utilize the IaaS environment and ensure their applications and data are properly deployed, managed, and protected.
