    Study Notes

    Cloud Computing Basics

    • Cloud computing uses hosted services (data storage, servers, databases, networking, and software) over the internet.
    • Data is stored on physical servers maintained by a cloud service provider.
    • Computer system resources (data storage, computing power) are available on-demand, without direct user management.

    Cloud Computing Architecture

    • Cloud computing involves a front-end layer (user interaction) and a back-end layer (software and hardware components).
    • The back-end layer includes servers, central servers, and databases.

    Cloud Computing Models

    • Infrastructure as a Service (IaaS): The cloud service provider offers infrastructure components like servers, networking, and storage, allowing users to manage the virtualization layer.
    • Platform as a Service (PaaS): Vendor offers infrastructure and services for many functions, commonly used in software development. Services and products are often utilized to perform software development processes.
    • Software as a Service (SaaS): A wide range of business technologies (HRM, CRM) are offered and hosted online by the vendor.

    Cloud Deployment Models

    • Public Cloud: Accessible to the public, ideal for fluctuating demands and low-security concerns.
    • Private Cloud: Hosted and managed within an organization's data center or by a third-party vendor. Offers greater control over data and resources compared to public clouds.
    • Community Cloud: Shared by a group of organizations that have common objectives and use cases.
    • Hybrid Cloud: Combines public and private cloud environments, used for storing sensitive data in the private cloud and non-critical data in the public cloud.

    Cloud Service Providers

    • Deliver cloud services to end-users/consumers.

    Key Cloud Actors (NIST Model)

    • Cloud Provider: Delivers cloud services.
    • Cloud Carrier: Mediates connectivity between cloud providers and consumers.
    • Cloud Broker: Enhances services and manages performance for consumers.
    • Cloud Auditor: Assesses security, performance, and operation of cloud services.
    • Cloud Consumer: End-user who utilizes cloud services.

    Cloud Cube Model

    • Internal/External: Data location affects accessibility.
    • Proprietary/Open: Ownership and data sharing (proprietary systems vs. open technologies).
    • Perimeterized/De-Perimeterized: Boundaries in cloud computing (traditional vs. innovative techniques).
    • Insourced/Outsourced: In-house vs. third-party service providers.

    Identity as a Service (IDaaS)

    • Definition: Cloud service offering identity and access management.
    • Core Components: Authentication, Single Sign-On, Access Management, Directory Services, and Lifecycle Management.

    Compliance as a Service (CaaS)

    • Definition: A cloud-based service for managing compliance requirements.
    • Core Components: Regulatory Compliance Management, Policy Management, and Risk Management, including audit/reporting, training, and awareness.
