Study Notes

Importance of Hardware Level Virtualization

Enables multiple operating systems to run simultaneously on a single host computer by abstracting hardware resources.
Enhances efficiency by allowing several virtual machines (VMs) to utilize one physical machine, minimizing hardware requirements.
Ensures strong isolation between VMs, improving security and stability.
Offers flexibility for managing diverse workloads through the ability to run different operating systems.
Facilitates scalability; new VMs can be created swiftly to address changing demands.
Promotes cost savings by consolidating multiple servers into fewer physical machines, reducing expenses for hardware, power, and cooling.

Importance of Machine Reference Model

Functions as a conceptual framework detailing the interactions among various layers of a computing system, essential for virtualization.
Features layered abstraction, simplifying management and implementation by distinguishing hardware, operating systems, and applications.
Ensures portability by defining standard interfaces, allowing applications and operating systems to operate on different hardware without modifications.
Enhances security through the isolation of different layers, reducing risks of unauthorized access.
Promotes interoperability between systems and components, ensuring efficient communication and operation.

Types of Services Provided by Cloud Computing

Infrastructure as a Service (IaaS):
- Offers virtualized computing resources via the internet, allowing users to rent VMs, storage, and networks.
- Case Study: Amazon Web Services (AWS) utilized by Netflix for dynamic scaling based on demand, ensuring robust availability and performance.
Platform as a Service (PaaS):
- Provides a platform for customers to develop, run, and manage applications without managing underlying infrastructure.
- Case Study: Google App Engine is employed by Snapchat for rapid application development and deployment, leveraging Google’s scalable infrastructure.
Software as a Service (SaaS):
- Delivers software applications over the internet on a subscription basis, eliminating the need for local installation.
- Case Study: Salesforce is widely utilized for customer relationship management (CRM), enabling efficient management of customer interactions and data.

Implementation of Community Clouds

Community clouds are collaborative infrastructures created for specific communities sharing common goals like security and compliance.
Implementation involves pooling resources from various organizations to serve the unique needs of the community, achieving a blend of public and private cloud benefits.
