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
