Answer Key and Explanations:
What is cloud computing? Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Think of it as accessing computing resources over the internet, like electricity from a power grid.
Name three major cloud service models. Briefly describe each. The three major cloud service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides virtualized computing resources (servers, storage, networking); PaaS provides a platform for developing and deploying applications; SaaS provides software applications over the internet.
What is the difference between IaaS, PaaS, and SaaS? Give an example of each. IaaS: You manage the operating system and applications (e.g., Amazon EC2). PaaS: You manage the applications, the provider manages the operating system and underlying infrastructure (e.g., Google App Engine). SaaS: You only use the application; the provider manages everything (e.g., Salesforce).
Explain the concept of virtualization in relation to cloud computing. Virtualization allows a single physical server to run multiple virtual machines (VMs), each acting like a separate computer. This is crucial for cloud computing's scalability and efficiency.
What are some benefits of using cloud computing? Cost savings, scalability, increased efficiency, improved collaboration, enhanced security (in some cases), and data backup and disaster recovery.
What are some drawbacks or challenges associated with cloud computing? Vendor lock-in, security concerns (data breaches, vulnerabilities), internet dependency, compliance issues, and potential for downtime.
Describe the difference between public, private, and hybrid cloud deployments. Public cloud: shared resources, accessible via the internet (e.g., AWS). Private cloud: dedicated resources for a single organization. Hybrid cloud: a combination of public and private cloud resources.
What is cloud storage, and what are its advantages? Cloud storage is the storage of data on servers accessible via the internet. Advantages include accessibility from anywhere, scalability, cost-effectiveness, and data backup/recovery.
Explain the concept of serverless computing. Serverless computing is a cloud computing execution model where the cloud provider dynamically manages the allocation of computing resources. You pay only for the compute time consumed by your code.
What is a virtual machine (VM)? A virtual machine is a software emulation of a physical computer system. It allows multiple operating systems to run on a single physical server.
What are some key security considerations when using cloud computing? Data encryption, access control, identity and access management (IAM), regular security audits, and compliance with relevant regulations (e.g., GDPR, HIPAA).
What is cloud bursting? Cloud bursting is a technique where applications running on a private cloud can seamlessly scale up to a public cloud during peak demand.
What is a container (e.g., Docker)? How does it relate to cloud computing? A container is a standardized unit of software that packages code and its dependencies. Containers make it easier to deploy and manage applications in cloud environments.
Explain the concept of microservices architecture in relation to cloud computing. Microservices is an architectural style where an application is structured as a collection of small, independent services. This is well-suited for cloud deployments due to its scalability and flexibility.
What is a cloud provider? Name three major cloud providers. A cloud provider is a company that offers cloud computing services. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Scoring: Give yourself one point for each correctly answered question. A score of 10 or more indicates a strong understanding of cloud computing. A score of 5-9 indicates a moderate understanding, and a score below 5 suggests a need for further study.

This quiz provides a foundation for understanding cloud computing. Remember that cloud technology is constantly evolving, so continuous learning is essential to stay current with the latest advancements and best practices.
