300 QUESTIONS AND ANSWERS
1. Q: What is cloud computing? A: Cloud computing is the delivery of
computing services including servers, storage, databases, networking, software,
analytics, and intelligence over the internet to offer faster innovation, flexible
resources, and economies of scale.
2. Q: What are the three main cloud service models? A: Infrastructure as a
Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
3. Q: What is IaaS? A: Infrastructure as a Service provides virtualized
computing resources over the internet, including virtual machines, storage, and
networking components.
4. Q: What is PaaS? A: Platform as a Service provides a platform allowing
customers to develop, run, and manage applications without dealing with the
complexity of building and maintaining infrastructure.
5. Q: What is SaaS? A: Software as a Service delivers software applications
over the internet, on a subscription basis, eliminating the need for installation
and maintenance.
6. Q: What are the four cloud deployment models? A: Public cloud, Private
cloud, Hybrid cloud, and Community cloud.
7. Q: What is a public cloud? A: A public cloud is owned and operated by
third-party cloud service providers, delivering computing resources over the
internet to multiple organizations.
8. Q: What is a private cloud? A: A private cloud is used exclusively by one
organization, providing greater control over data, security, and quality of
service.
,9. Q: What is a hybrid cloud? A: A hybrid cloud combines public and private
clouds, allowing data and applications to be shared between them for greater
flexibility and deployment options.
10. Q: What is cloud elasticity? A: Cloud elasticity is the ability to
automatically scale computing resources up or down based on demand, ensuring
optimal performance and cost efficiency.
11. Q: What is cloud scalability? A: Cloud scalability is the ability to increase
or decrease computing resources to accommodate changing workload demands.
12. Q: What is the difference between vertical and horizontal scaling? A:
Vertical scaling (scaling up) increases the power of existing machines, while
horizontal scaling (scaling out) adds more machines to the resource pool.
13. Q: What is multi-tenancy in cloud computing? A: Multi-tenancy is an
architecture where a single instance of software serves multiple customers, with
each tenant's data isolated and secure.
14. Q: What are the key benefits of cloud computing? A: Cost reduction,
scalability, flexibility, automatic updates, increased collaboration, work from
anywhere, document control, security, and competitiveness.
15. Q: What is cloud bursting? A: Cloud bursting is a configuration that
allows private cloud resources to "burst" into public cloud resources when
demand exceeds private cloud capacity.
16. Q: What is a Virtual Private Cloud (VPC)? A: A VPC is a secure,
isolated private cloud hosted within a public cloud, providing the benefits of
public cloud with added security and control.
17. Q: What is serverless computing? A: Serverless computing is a cloud
execution model where the cloud provider manages server infrastructure, and
applications are broken down into individual functions.
18. Q: What is edge computing? A: Edge computing brings computation and
data storage closer to the location where it's needed, reducing latency and
bandwidth usage.
19. Q: What is cloud orchestration? A: Cloud orchestration is the automated
arrangement, coordination, and management of cloud services, systems, and
software.
20. Q: What is cloud provisioning? A: Cloud provisioning is the allocation of
cloud provider resources and services to customers, either automatically or on-
demand.
, 21. Q: What is Infrastructure as Code (IaC)? A: IaC is the practice of
managing and provisioning computing infrastructure through machine-readable
definition files, rather than physical hardware configuration.
22. Q: What is a cloud service level agreement (SLA)? A: An SLA is a
contract between a cloud service provider and customer that defines the level of
service expected, including uptime guarantees and performance metrics.
23. Q: What is cloud migration? A: Cloud migration is the process of moving
data, applications, or other business elements from on-premises infrastructure to
cloud computing environments.
24. Q: What are the main cloud migration strategies? A: Rehost (lift and
shift), Refactor, Revise, Rebuild, Replace, and Retire.
25. Q: What is cloud governance? A: Cloud governance is the set of policies,
procedures, and controls that guide how cloud resources are used within an
organization.
26. Q: What is cloud compliance? A: Cloud compliance ensures that cloud
services meet specific regulatory, legal, and industry standards for data
protection and security.
27. Q: What is cloud vendor lock-in? A: Vendor lock-in occurs when
switching from one cloud provider to another becomes difficult due to
proprietary technologies, data formats, or APIs.
28. Q: What is cloud federation? A: Cloud federation is the practice of
interconnecting cloud computing environments from multiple providers to
create a unified resource pool.
29. Q: What is cloud automation? A: Cloud automation uses software tools
and methodologies to reduce manual effort in provisioning and managing cloud
computing workloads and services.
30. Q: What is a cloud broker? A: A cloud broker is an entity that manages
cloud services for organizations, including service integration, aggregation, and
customization.
31. Q: What is cloud monitoring? A: Cloud monitoring involves tracking and
analyzing the performance, availability, and security of cloud-based
applications and infrastructure.
32. Q: What is cloud backup? A: Cloud backup is the process of copying and
storing data in a remote, cloud-based server for protection against data loss.
