Study Notes
Importance of Hardware Level Virtualization
- Hardware-level virtualization creates virtual versions of physical hardware (CPUs, memory, storage, network resources).
- Resource efficiency is achieved by allowing multiple virtual machines (VMs) to run on a single physical machine, optimizing hardware utilization.
- Reduces hardware needs, leading to lower operational costs and reduced power consumption.
- Each VM operates in an isolated environment, enhancing security and preventing a single VM's failures from impacting others.
- Flexibility in resource allocation allows users to easily scale resources for VMs without physical modifications, accommodating changing workloads.
- Facilitates disaster recovery through simple backup and restoration processes for virtual machines, essential for business continuity.
- Supports development and testing processes by enabling the creation of multiple test environments on the same hardware.
Importance of the Machine Reference Model
- The Machine Reference Model (MRM) provides a standardized description of computer systems, promoting better communication among stakeholders.
- A clear blueprint of machine functioning aids in the design and analysis of computer architectures, predicting impacts of changes.
- Helps identify bottlenecks and inefficiencies in systems, enabling targeted optimizations for better performance.
- Serves as an educational tool, simplifying complex computer architecture concepts for students.
- Allows valid comparisons between different computer architectures using a common framework, facilitating evaluations of their advantages and disadvantages.
Types of Services Provided by Cloud Computing
-
Infrastructure as a Service (IaaS): Virtualized computing resources provided over the internet.
- Example: Amazon Web Services (AWS), which enables businesses to rent VMs and storage.
- Case Study: Netflix uses AWS IaaS to manage its content delivery network, scaling infrastructure based on demand.
-
Platform as a Service (PaaS): Offers a platform for developing, running, and managing applications without infrastructure complexities.
- Example: Google App Engine, which supports developers in building applications.
- Case Study: Coca-Cola utilizes Google Cloud Platform (GCP) to develop its loyalty program application.
-
Software as a Service (SaaS): Delivers software applications on a subscription basis over the internet.
- Example: Microsoft 365, providing cloud-hosted Office applications to businesses.
- Case Study: Slack acts as a SaaS platform widely adopted for team collaboration and communication.
-
Function as a Service (FaaS): Allows developers to execute code in response to events without managing servers.
-
