In developing a disaster recovery plan, which type of cloud service is preferred for secure file storage and backups?

1. IaaS

2. PaaS

3. SaaS

4. FaaS

The correct answer is: SaaS

The choice of Software as a Service (SaaS) for secure file storage and backups in a disaster recovery plan is favored due to its specific advantages in managing data securely and efficiently. SaaS applications typically provide built-in solutions for data handling, including encryption, access controls, and compliance with regulatory requirements, all of which are essential for secure storage and backup. SaaS also often includes automated backups, which are critical for disaster recovery, as they help ensure that the most current and relevant data is securely saved and can be easily restored when necessary. Additionally, the managed nature of SaaS means that the service provider is responsible for maintaining the infrastructure, which allows organizations to focus on their core competencies rather than IT management. In contrast, Infrastructure as a Service (IaaS) provides raw computing resources, requiring users to handle their own installation and management of storage solutions. Platform as a Service (PaaS) focuses on providing a platform for application development and may not be directly tailored for secure file storage. Function as a Service (FaaS), which emphasizes executing code in response to events, is more suited for event-driven architectures rather than for storage solutions. Overall, the functionality and support structures offered by SaaS make it particularly well-s
