    What is cloud computing?

    Enables on-demand access to shared computing resources.

    What are the benefits of cloud computing?

    Reduces initial costs and allows flexible resource access.

    How does a public cloud differ from a private cloud?

    Public clouds are shared among multiple users; private clouds are dedicated to a single organization.

    What is a hybrid cloud?

    Combines public and private clouds for greater flexibility.

    What does IaaS stand for?

    Infrastructure as a Service, providing virtualized computing resources.

    What is the role of a hypervisor?

    Manages multiple virtual machines on a single hardware host.

    What is multi-tenancy in cloud computing?

    Allows multiple customers to share the same application instance.

    What are the main security concerns in cloud computing?

    Data privacy, access control, and identity management.

    What is the purpose of Trusted Third Party (TTP) in cloud security?

    Facilitates trust and ensures data integrity and confidentiality.

    How does SaaS differ from IaaS?

    SaaS delivers software applications; IaaS provides hardware resources.

    What is the significance of cryptography in cloud security?

    Ensures data confidentiality and integrity during transmission.

    What is the impact of virtualization on cloud security?

    Introduces complexity and new attack vectors for securing resources.

    What happens if data integrity is compromised in the cloud?

    Data may be modified or lost, affecting trust and reliability.

    What is the role of Public Key Infrastructure (PKI)?

    Provides a framework for secure data exchange and authentication.

    What are the challenges of cloud storage security?

    Data leakage, unauthorized access, and management of encryption keys.

    What does the term 'availability' mean in cloud computing?

    Ensures authorized users can access services at all times.

    How does a community cloud operate?

    Shared infrastructure among organizations with common concerns.

    What is the difference between PaaS and SaaS?

    PaaS provides a platform for application development; SaaS delivers ready-to-use applications.

    What is the significance of Service Level Agreements (SLA)?

    Defines the expected service performance and responsibilities of providers.

    What are the implications of data remanence in cloud computing?

    Residual data may be recoverable, posing privacy risks.
