Study Notes
Types of Virtualizations
- Server Virtualization: Splits a physical server into multiple virtual servers, each with its own operating system. Enhances resource utilization, lowers hardware costs, and simplifies management.
- Storage Virtualization: Merges several physical storage devices into a single virtual unit. Improves data management, availability, and streamlines backup and recovery.
- Network Virtualization: Abstracts physical network resources into virtual networks, boosting efficiency, scalability, and security.
- Data Virtualization: Offers a unified view of data from various sources without relocating it, simplifying access and improving integration and management.
- Desktop Virtualization: Hosts desktop environments on a central server for end-users, easing management, enhancing security, and reducing hardware expenditures.
- Application Virtualization: Executes applications in a virtual context that is separate from the operating system, simplifying deployment, minimizing conflicts, and strengthening security.
- GPU Virtualization: Allocates GPU resources among multiple virtual machines, optimizing performance for graphics-intensive applications.
- Memory Virtualization: Converts physical memory into a virtual memory pool to enhance utilization and application performance.
Innovative Characteristics and Benefits of Cloud Computing
- On-Demand Self-Service: Users can independently provision resources as required, eliminating the need for human intervention.
- Broad Network Access: Resources can be accessed via standard mechanisms over the network.
- Resource Pooling: Providers consolidate resources to serve multiple clients using a multi-tenant approach.
- Rapid Elasticity: Resources can be quickly scaled up or down in response to demand fluctuations.
- Measured Service: Resource usage is tracked and reported, ensuring transparency for users and providers.
- Cost Efficiency: Minimizes upfront capital costs associated with hardware and software investments.
- Scalability: Resources can easily adjust to varying demand levels.
- Accessibility: Users can access resources from anywhere with internet connectivity.
- Collaboration: Facilitates teamwork by enabling multiple users to simultaneously work on projects.
- Disaster Recovery: Provides comprehensive backup and disaster recovery solutions.
- Automatic Updates: Keeps users up-to-date with the latest technology without requiring manual updates.
Applying Cloud Computing Architecture to Implement Infrastructure as a Service (IaaS)
-
Architecture Components:
- Virtual Machines (VMs): Deliver virtualized computing capabilities.
- Storage: Provides scalable storage options tailored to needs.
- Networking: Incorporates virtual networks, load balancers, and firewalls for connectivity and security.
- Management Tools: Facilitate resource management and monitoring.
-
Implementation Steps:
- Provisioning: Establish virtual machines, storage, and networking resources.
- Configuration: Set up the virtual environment according to specific requirements.
- Deployment: Launch applications and services on the virtual infrastructure.
- Management: Utilize management tools for ongoing monitoring and resource optimization.
Concept of Public Cloud with Suitable Cloud Service Providers
- Public Cloud: A cloud computing model that allows multiple users or organizations to share resources while being managed by a third-party service provider, facilitating cost-effectiveness and reduced management overhead.
