    Study Notes

    Virtualization Platform Overview

    • Essential for creating a Virtual Resource Pool composed of multiple Virtual Machines (VMs).
    • Hypervisor enables direct management of physical machine CPU and memory resources.

    Components of the Virtual Resource Pool

    • Comprises hardware resources (CPUs, memory, and network connectivity) on physical servers.
    • Hypervisor software facilitates the operating system environment for VMs and dynamic resource allocation.

    Hypervisor and Virtual OS

    • VMware vSphere is the preferred hypervisor for accessing physical computing and memory resources.
    • Supports the deployment of IoT Cloud services on VMs, ensuring high performance at reduced costs.

    Data Storage in IoT Applications

    • Data from IoT applications can be stored in either SQL (relational) or NoSQL (non-relational) databases.
    • NoSQL databases are favored for real-time IoT applications due to their suitability for complex data types and scalability.

    Importance of Load-Balancing Servers

    • Process requests systematically to enhance performance.
    • Distribute workloads across application and database servers effectively.
    • Prevent congestion, maximizing productivity and resource utilization.

    Application Domains of IoT Cloud Platform

    • Encompasses various domains including:
      • Application development
      • Device management
      • Virtualization
      • Research and analytics
      • Deployment management
      • Data management
      • Monitoring management
      • Heterogeneity management
      • System management
