    Study Notes

    Cloud Computing Definition

    • Cloud computing is defined by NIST within three main parts:
      • Five Essential Characteristics:
        • On-demand self-service
        • Broad network access
        • Resource pooling
        • Rapid elasticity
        • Measured service
      • Four Cloud Deployment Models: Public, Private, Community, Hybrid
      • Three Cloud Service Models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS)

    History of Cloud Computing

    • Cloud computing origins trace back to the 1950s with the rise of large-scale mainframe computers in corporations.
    • Time-sharing emerged as a way to efficiently utilize expensive mainframes by allowing multiple users to share access and CPU time.
    • In the 1990s, telecommunications companies began offering VPN services, using the "cloud" symbol to represent the boundary between provider and user responsibilities.
    • The term "Dynamic Web" emerged to describe the shift from document-centric to more service-oriented uses of the internet.
    • Cloud computing witnessed rapid growth due to advancements in high-speed networks, affordable computing & storage, hardware virtualization, and service-oriented architecture.
    • Amazon pioneered cloud computing by modernizing its data centers and launching Amazon Web Services (AWS) in 2006.

    Similar Systems and Concepts

    • Cloud computing builds upon existing technologies and paradigms, offering a way to benefit from these technologies without needing advanced expertise.
    • Virtualization is a key enabling technology, allowing for cost reduction by shifting capital expenditures to operational expenditures.
    • Cost reduction is further achieved through utility storage and computing, which are typically cheaper than specialized components.
    • Device and location independence enable users to access systems via web browsers from any location and device.
    • Multitenancy promotes resource sharing and cost reduction by centralizing infrastructure, increasing peak-load capacity, and improving system utilization.
    • Metered by Use allows for flexible payment models based on usage, including "pay-as-you-go," subscriptions, fixed plans, and free plans.
    • Services are delivered using Internet technologies and protocols like URLs, HTTP, and IP, as exemplified by services like Gmail, Amazon book buying, eBay auctions, and Lolcats.

    Cloud Deployment Models

    • Public Clouds: All systems and resources are located at an external service provider, accessible via the internet.
    • Private Clouds: Systems and resources are located internally within a company or organization, accessed via local LAN/WAN or remote access with controlled security.
    • Community Clouds: Semi-public clouds shared by organizations with a common purpose, offering more privacy than public clouds while sharing responsibility for maintenance.
    • Hybrid Clouds: Combine two or more cloud models, enabling greater flexibility and complexity to meet organizational goals.

    Cloud Service Models

    • Infrastructure as a Service (IaaS): Provides basic infrastructure services such as physical machines, virtual machines, networking, and storage, allowing users to build their own infrastructure.
    • Platform as a Service (PaaS): Offers an operating system, development platform, and database platform, enabling organizations to develop applications without managing infrastructure.
    • Software as a Service (SaaS): Provides complete applications and data services, including the necessary platforms and infrastructure, for services like CRM and ERP.

    Benefits of Cloud Computing

    • Elasticity: Pay-as-you-go pricing, allowing applications to expand and contract on demand across all tiers, ensuring scalability and financial efficiency.
    • User Self-Provisioning (Cloud Self-Service): Enables users to set up and launch applications and services without direct IT help, promoting user autonomy.
    • Business Expansion: Facilitates rapid scaling of infrastructure to accommodate growth, minimizing capital expenditure and maximizing flexibility.
    • Global Expansion: Enables deployment of data centers in a pay-per-use fashion in global markets, facilitating international expansion.
    • Core Competency - Flexibility: Allows organizations to focus their efforts on core business operations by outsourcing IT hosting and infrastructure management.
    • Security: Cloud hosts specialize in security monitoring, offering improved security and compliance compared to in-house solutions.
    • Mobility: Provides mobile access to corporate data via smartphones and devices, enhancing flexibility and collaboration.
    • Insight and Data Analysis: Many cloud-based storage solutions integrate data analytics for comprehensive data insights.
