Question 1

Define Cloud Computing.

Accepted Answer

Cloud Computing is the mathematical and architectural abstraction of physical hardware, delivering on-demand computing resources (servers, storage, databases) over the internet with pay-as-you-go pricing.

Question 2

What are the essential characteristics of Cloud Computing?

Accepted Answer

The NIST mathematically defined essential characteristics are On-demand self-service, Broad network access, Massive resource pooling, Rapid elasticity, and strict Measured service.

Question 3

What is Platform as a Service (PaaS)?

Accepted Answer

PaaS is a cloud service architecture that provides software developers with a complete, pre-configured development and deployment environment, abstracting away underlying OS and server management.

Question 4

Differentiate between public and private clouds.

Accepted Answer

Public clouds mathematically share massive physical hardware across millions of distinct corporate tenants, whereas Private clouds rigidly dedicate absolute physical hardware to one single corporation.

Question 5

What is a hypervisor?

Accepted Answer

A hypervisor (Virtual Machine Monitor) is the absolute core software architecture that mathematically slices a single physical server into multiple isolated Virtual Machines (VMs).

Question 6

Define Grid Computing.

Accepted Answer

Grid Computing is a decentralized mathematical architecture that violently aggregates geographically distributed, heterogeneous computers into a single massive supercomputer to solve horrific computational problems.

Question 7

What is MapReduce?

Accepted Answer

MapReduce is a highly aggressive distributed programming model that mathematically splits massive datasets, processes them in parallel (Map), and aggregates the outputs (Reduce).

Question 8

Mention any two security challenges in Cloud Computing.

Accepted Answer

Two absolute catastrophic security challenges in Cloud Computing are Data Breach vulnerabilities due to hypervisor failure and massive Distributed Denial of Service (DDoS) resource exhaustion.

Question 9

What is Service Level Agreement (SLA) in Cloud Computing?

Accepted Answer

An SLA is a strict, legally binding mathematical contract between a cloud provider and a client that dictates absolute uptime guarantees and financial penalties.

Question 10

Name any two open-source cloud computing platforms.

Accepted Answer

Two dominant open-source cloud architectures are OpenStack (used for massive IaaS deployments) and Apache CloudStack.
