1. What is cloud computing? Cloud computing is the delivery of computing
services including servers, storage, databases, networking, software, analytics,
and intelligence over the Internet ("the cloud") to offer faster innovation,
flexible resources, and economies of scale.
2. What are the three main cloud service models? The three main cloud
service models are IaaS (Infrastructure as a Service), PaaS (Platform as a
Service), and SaaS (Software as a Service).
3. What is IaaS? IaaS (Infrastructure as a Service) provides virtualized
computing resources over the internet, including virtual machines, storage, and
networking infrastructure.
4. What is PaaS? PaaS (Platform as a Service) provides a platform allowing
customers to develop, run, and manage applications without dealing with the
underlying infrastructure.
5. What is SaaS? SaaS (Software as a Service) delivers software applications
over the internet on a subscription basis, eliminating the need for local
installation and maintenance.
6. What are the four main cloud deployment models? The four main
deployment models are public cloud, private cloud, hybrid cloud, and multi-
cloud.
7. What is a public cloud? A public cloud is a cloud infrastructure owned and
operated by a third-party cloud service provider, where resources are shared
among multiple organizations.
8. What is a private cloud? A private cloud is cloud infrastructure exclusively
used by a single organization, either hosted on-premises or by a third party.
9. What is a hybrid cloud? A hybrid cloud combines public and private
clouds, allowing data and applications to be shared between them for greater
flexibility and optimization.
,10. What is multi-cloud? Multi-cloud refers to using cloud services from
multiple cloud providers to avoid vendor lock-in and optimize for specific
capabilities.
11. What are the main benefits of cloud computing? Key benefits include
cost savings, scalability, flexibility, disaster recovery, automatic updates,
collaboration capabilities, and reduced time to market.
12. What is elasticity in cloud computing? Elasticity is the ability to
automatically scale resources up or down based on demand, ensuring optimal
performance and cost efficiency.
13. What is scalability in cloud computing? Scalability is the capability to
increase or decrease IT resources as needed to meet changing demand, either
vertically (scaling up) or horizontally (scaling out).
14. What is vertical scaling? Vertical scaling (scaling up) involves adding
more power (CPU, RAM) to an existing machine to handle increased load.
15. What is horizontal scaling? Horizontal scaling (scaling out) involves
adding more machines or instances to distribute the workload across multiple
resources.
16. What is cloud bursting? Cloud bursting is a hybrid cloud deployment
model where an application runs in a private cloud but bursts into a public cloud
when demand spikes.
17. What is a virtual machine (VM)? A virtual machine is a software-based
emulation of a physical computer that runs an operating system and applications
as if it were a physical machine.
18. What is virtualization? Virtualization is the technology that allows
multiple virtual machines to run on a single physical machine, sharing hardware
resources.
19. What is a hypervisor? A hypervisor is software that creates and manages
virtual machines by separating the physical hardware from the virtual
environments.
20. What are the two types of hypervisors? Type 1 (bare-metal) hypervisors
run directly on hardware, while Type 2 (hosted) hypervisors run on top of an
operating system.
21. What is containerization? Containerization is a lightweight form of
virtualization that packages an application and its dependencies together to run
consistently across environments.
, 22. What is Docker? Docker is a popular platform for developing, shipping,
and running applications in containers.
23. What is Kubernetes? Kubernetes is an open-source container orchestration
platform that automates the deployment, scaling, and management of
containerized applications.
24. What is serverless computing? Serverless computing is a cloud execution
model where the cloud provider manages the infrastructure, and developers only
focus on writing code that runs in response to events.
25. What is Function as a Service (FaaS)? FaaS is a serverless computing
model where developers write and deploy individual functions that execute in
response to events without managing servers.
26. What is auto-scaling? Auto-scaling is the automatic adjustment of
computational resources based on current demand to maintain performance and
optimize costs.
27. What is load balancing? Load balancing distributes incoming network
traffic across multiple servers to ensure no single server becomes overwhelmed
and to improve availability.
28. What is a content delivery network (CDN)? A CDN is a distributed
network of servers that delivers web content to users based on their geographic
location, improving speed and reducing latency.
29. What is latency in cloud computing? Latency is the time delay between a
user's action and the response from the cloud service, typically measured in
milliseconds.
30. What is bandwidth? Bandwidth is the maximum rate of data transfer
across a network path, typically measured in bits per second (bps).
31. What is throughput? Throughput is the actual amount of data successfully
transferred from one point to another in a given time period.
32. What is a region in cloud computing? A region is a separate geographic
area where cloud providers have data centers, allowing customers to deploy
resources closer to users.
33. What is an availability zone? An availability zone is an isolated location
within a region that contains one or more data centers with redundant power,
networking, and connectivity.
