    Study Notes

    Introduction to Cloud Computing

    • Cloud computing involves accessing servers, software, and databases over the internet.
    • Cloud servers are located in data centers globally.
    • Users and businesses don't need to manage physical servers or software locally.
    • Cloud computing relies on sharing resources (e.g., data storage, computing power).
    • The "pay-as-you-go" model common in cloud computing can reduce capital expenses but might increase operational costs.

    Evolution of Cloud Computing

    • Cloud computing's roots trace back to the 1950s.
    • Core technologies include distributed systems, virtualization, web 2.0, service orientation, and utility computing.
    • Mainframe computing (1950s): Powerful, reliable machines handling large data (e.g., transactions).
    • Distributed computing: Multiple independent systems sharing resources.
    • Cluster computing (1980s): Cheaper alternative to mainframes, with interconnected machines.
    • Grid computing (1990s): Distributed globally, leveraging network connections.
    • Virtualization: Allows running multiple instances simultaneously on a single hardware layer.
    • Web 2.0: Modern interface for cloud computing services, enabling user interaction.
    • Service orientation: Model for cloud services' provisioning.
    • Utility computing: Computing services provided on a pay-per-use basis.
    • Cloud computing is considered the successor to grid computing

    Cloud Computing Characteristics

    • On-demand self-service: Users can access resources, configure applications, and monitor their usage automatically.
    • Broad network access: Cloud resources are available over standard mechanisms such as mobile phones, laptop, desktops and tablets. Resources can be accessed virtually anywhere globally without any limitations.
    • Resource pooling: Computing resources are pooled to serve multiple consumers using a multi-tenant model. Resources are allocated and re-allocated in response to demand.
    • Rapid elasticity: Resources can be scaled up or down automatically to respond to fluctuating demands.
    • Measured Service: Resource usage is monitored and managed by the provider. Users are charged only for consumed resources.

    Types of Cloud Computing

    • Public Cloud: Resources are made available to the general public, managed by a third-party provider, and are 'pay-per-use'.
    • Private Cloud: Resources are dedicated to a single organization, either on-premises or managed by a third-party.
    • Hybrid Cloud: Combines resources from public and private clouds, offering flexibility and scalability.
    • Community Cloud: Infrastructure shared by a group of organizations with common concerns, typically managed internally or externally.

    Cloud Services (Reference Model)

    • Infrastructure-as-a-Service (IaaS): Provides servers, networking, and storage to run arbitrary software (operating systems and applications).
    • Platform-as-a-Service (PaaS): Provides the platform for developing and deploying applications using programming languages and tools provided by the provider.
    • Software-as-a-Service (SaaS): Provides access to software applications over the internet, allowing users to use applications supplied by the provider or with minimal control of the infrastructure.

    Cloud Storage

    • A cloud computing model storing data via the internet.
    • Data storage that can be accessed anytime, anywhere, with global scale, and durability.
    • Types of cloud storage include object storage (for general applications and large files), file storage (for files and documents), and block storage (for databases and applications).

    Cloud Adoption Challenges

    • Making the right choice: Determining suitability for organization needs and potential risks.
    • Loss of Control: Issues over data security, management of data, and third-party involvement.
    • Vendor Lock-in: Inability to easily switch vendors without data migration issues.
    • Security and Compliance: Meeting data security and regulatory requirements.
    • Availability and Reliability: Ensuring continuous access and performance of cloud services.
    • Lack of skills and expertise: Understanding cloud technologies and managing resources efficiently.
    • Performance and bandwidth costs: Matching bandwidth speed to application needs.
    • Integration with existing infrastructure: Challenges adapting cloud services to current systems.

    Cloud Adoption Strategies

    • Organizations adapt to cloud computing differently based on their needs and resources.
    • The strategies include: public versus private cloud solutions, managing privileged data, and compliance with security standards.

    Cloud Storage Requirements

    • Data needs to be durable (redundant facilities and devices) and available for use.
    • Data access should be secure, and compliant with industry or regulatory standards.
