1 Describe the IaaS, PaaS, and SaaS models?
IaaS: Infrastructure-as-a-Service or IaaS lets you create
cloud-based infrastructure (servers, networks, and so on) in
the cloud. Like on-premises, but without the complexity of
data centers or infrastructure.
2 What are the main characteristics of cloud
computing?
The key characteristics of cloud computing are as follows:
Interview Questions
PaaS: Platform-as-a-Service or PaaS allows you to develop
software on a cloud-based platform without worrying about
infrastructure deployment. Less stress regarding OS/Hardware,
but the greater power is given to the vendor.
1
SaaS: Software-as-a-Service or SaaS is a concept where the
provider manages practically everything, and you only use
the service, such as Office 365 or DropBox.

to meet increasing or decreasing demand is referred to as
scalability in cloud computing. It is one of the cloud’s defining
features and the key driver of its growing popularity among
enterprises.
7 What are the various levels that make up
cloud architecture?
Cloud architecture is divided into five layers, as follows:
Cloud Controller (CLC)
1
Storage Controller (SC)
2
Node Controller (NC)
3
Walrus
5
Cluster Controller

8 How can you keep your data safe when
transferred to the cloud?
The data must be encrypted, and it should be ensured that
data is not leaked while moving to the cloud to safeguard
data while migrating to the cloud.
9 What exactly is ‘EUCALYPTUS’?
EUCALYPTUS is the abbreviation for Elastic Utility Computing
Architecture for Linking Your Programs. It is commonly used
in the cloud computing platform to implement clusters to
establish public, hybrid, and private clouds.
10 What role does API play in cloud services?
API stands for Application Programming Interface. It is a critical
component of cloud platforms. It is employed in the following
contexts:
It specifies how one or more programs should communicate
with one another.
1
It enables us to use cloud services.
2
It also reduces the need to write entire programs.
4
It facilitates the building of applications and the integration
of cloud services with other platforms.

11 What role does the performance cloud play
in cloud computing?
The performance cloud enables the fastest possible data
transfer. It is commonly used by experts involved in high-
performance computing development.
13 What role does buffer play in Amazon Web
Services (AWS)?
A buffer is used to improve system efficiency in traffic or load.
It assists in the coordination of several components. The buffer
maintains the harmony between those components while also
causing them to work at the same speed to complete the
operation faster.
12 What is Amazon SQS?
Amazon SQS messages are utilized between Amazon
components to connect with various connectors. As a result,
Amazon SQS can be described as a communicator.
14 What exactly is a systems integrator?
A systems integrator in cloud computing is a person or firm
who specializes in compacting component subsystems and
ensuring that they work together.

15 Define geo-targeting in CloudFront?
Geo-targeting is a framework that enables organizations to
show personalized information to their audiences based on
their geographical location without changing the URL. This
allows you to produce customized content for a particular
geographical area’s audience while keeping their demands
in mind.
16 What stages are involved in implementing a
CloudFormation Solution?
Following are the steps:
Build a different CloudFormation framework or reuse an
existing one in JSON or YAML format.
1
Save the code to an S3 bucket that will be a storage for the
code.
2
CloudFormation examines the file, identifies the resources that
are called, their order, and the relationships between them,
and then provisions the services one by one.
4
To access the container and build a layer on your framework,
use AWS CloudFormation.

17 What are the benefits of Azure Autoscaling?
Autoscaling is a feature of Azure that allows automatic scaling.
Autoscaling assists in managing changing market conditions
in cloud services, mobile services, Virtual Machines (VMs),
and websites. Here are a few of its benefits:
18 In Azure SQL, what is Federation?
SQL Azure Federation is a set of tools that allow programmers
to access and share datasets in SQL Azure. For scalability,
Azure SQL has implemented Federation. It aids administrators
by facilitating data division and redistribution and data scaling.
It also assists developers with the routing layer and data
clustering and facilitates routing without causing application
downtime.
Improves application performance
In response to demand, scale up or down
Exceptionally cost-effective
1 It allows users to access information hosted in the cloud.
2 Users can create their databases or exchange databases with one another.
3 It minimizes the probability of a single point of failure.
