What are the Deployment Models in cloud computing?
Public cloud, Private cloud , Hybrid cloud, Community cloud
How does the pay-as-you-go pricing model in cloud computing help startups save money compared to buying physical servers?
The pay-as-you-go pricing model in cloud computing helps startups save money because they only pay for the cloud resources they actually use, instead of purchasing and maintaining expensive physical servers. It helps startups save money:
1. No Initial Investment
2. Pay for resource Usage
3. Reduced Maintenance Costs
4. Easy Scalability
5. Lower Operational Costs

Can you give two examples of popular hypervisor software used to create virtual machines?
VMware ESXi , KVM (kernel based Virtual machine)-Powers major cloud platforms like AWS, Google cloud
What is a hypervisor, and what role does it play in virtualization?
A hypervisor is software or firmware that creates, runs, and manages multiple virtual machines (VMs) on a single physical computer.
Role of a hypervisor in virtualization:
1. Creates Virtual Machines
2. Allocates Resources
3. Isolation
4. Resource Management
5. Runs Multiple Operating Systems

Why is physical hardware maintenance (such as cooling, cabling, and part replacement) eliminated in cloud computing?
Physical hardware maintenance is eliminated in cloud computing because the cloud service provider like Amazon, Microsoft or Google (CSP) owns and manages their own physical infrastructure, including servers, storage devices, networking equipment, cooling systems, and cabling. The cloud provider is responsible for:
- Cooling: Maintaining data centre temperatures.
- Cabling: Managing physical network connections.
- Part replacement: Repairing or replacing faulty hardware.
- Hardware maintenance: Monitoring and maintaining servers and storage devices.
