    Study Notes

    Cloud Computing Overview

    • Cloud computing allows users to access and use computing resources (e.g., servers, storage, databases) over the internet.
    • Cloud storage refers to saving data on remote servers, which can be accessed via the internet instead of being stored on local hard drives.

    Infrastructure as Software

    • Infrastructure as Software (IaaS) enables users to provision and manage IT infrastructure components without needing physical hardware, offering virtual machines, storage, and networks.

    Basic Cloud Service Models

    • Three primary cloud service models:
      • Infrastructure as a Service (IaaS)
      • Platform as a Service (PaaS)
      • Software as a Service (SaaS)

    Advantages of Cloud Computing

    • Reduces capital expenditure by allowing companies to pay for services as needed (variable expense).
    • Provides scalability and flexibility to adjust resources based on demand.
    • Enhances collaboration and accessibility of applications from anywhere.
    • Addresses issues related to server capacity management, improving efficiency.

    Challenges of Cloud Computing

    • Security concerns regarding data protection and privacy.
    • Reliability and potential service outages impacting access and performance.
    • Regulatory compliance challenges due to varying laws across regions.

    Policy and Organizational Challenges

    • Organizational resistance to change due to traditional IT practices.
    • Governance issues related to data ownership and access control.

    Technical Issues in Cloud Computing

    • Significant technical challenges include integration with on-premises systems.
    • Performance bottlenecks can occur if not properly managed.
    • Licensing and intellectual property rights are significant legal challenges.
    • Jurisdictional issues may arise due to data hosted in different regions.

    Cloud Service Providers

    • Amazon Web Services (AWS) has the most availability zones among cloud providers.
    • Microsoft Azure’s Intelligent Cloud segment focuses on providing cloud services and solutions for enterprise businesses.
    • Google Cloud Platform has the fewest regions available compared to other major providers.

    Performance and Resource Management

    • Cloud service providers that excel in offering high availability often have more regions and availability zones.
    • IaaS provides the highest level of flexibility and control over IT resources.
    • PaaS allows organizations to focus primarily on application development rather than underlying infrastructure management.

    Deployment Models

    • Fully cloud-based deployment utilizes resources entirely in the cloud.
    • Hybrid deployment connects cloud-based infrastructure with on-premises resources for optimal flexibility.

    Cost Management Advantage

    • The advantage of converting capital expenses to operational expenses helps manage financial resources effectively.

    SaaS and IaaS Descriptions

    • SaaS offers end-users applications accessed via the internet without local installation needs.
    • IaaS provides access to essential infrastructure components like virtual machines and storage.

    Hybrid Deployment Connection

    • PaaS enables seamless integration of application development across both cloud and on-premises platforms.

    On-Premises Deployment

    • While on-premises deployment lacks many cloud computing benefits, it still provides control over sensitive data and legacy systems.
