Top Cloud Computing Interview Questions and Answer for Beginners

Let’s discuss some basic Cloud Computing Interview Questions and Answers for beginners or freshers:

Q.1 Explain Cloud.

Ans. A cloud is a collaboration of networks, hardware, services, storage, and interfaces that help in delivering computing as a service. It has three users:

  • End users
  • Business management users
  • Cloud service provider

Q.2 What is cloud computing?

Ans. A pay-as-you-go method of accessing and using computer resources, including servers, storage, databases, software, and networking, through the internet is known as cloud computing. In other words, it makes computer resources available to people and organisations without requiring them to buy and maintain physical infrastructure.

With the ability to use scalable and flexible computing resources, lower infrastructure costs, and concentrate on their core strengths without having to worry about managing real servers and hardware, cloud computing has emerged as a game-changing technology. Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and others are significant cloud service providers.

Q.3 Explain the key benefits of cloud computing?

Ans. The key benefits of cloud computing are:

  • Data backup and storage of data.
  • Powerful server capabilities.
  • Incremented productivity.
  • Very cost effective and time-saving.
  • Software as Service known as SaaS.

Q.4 Which are the different layers that define cloud architecture?

Ans. Below mentioned are the different layers that are used by cloud architecture:

  • Cluster Controller
  • SC or Storage Controller
  • NC or Node Controller
  • CLC or Cloud Controller
  • Walrus

Q.5 Explain Cloud Service Models?

Ans. The various tiers of cloud computing services offered by cloud service providers are referred to as cloud service models. These models provide various levels of administration, control, and accountability for the supporting systems and applications. The three primary models for cloud services are:

IAAS: The most fundamental cloud service architecture, infrastructure as a service (IaaS), makes virtualized computer resources available via the internet. It provides the basic building blocks of the IT infrastructure, including networking, storage, and virtual computers. Users may install and manage their apps and data on the cloud infrastructure in an IaaS environment, where they have more control over the underlying infrastructure.

Platform as a Service (PaaS): PaaS provides an environment and platform for developers to create, launch, and maintain applications without having to worry about the underlying infrastructure. The hardware, operating system, and software components required for the creation and use of applications are handled by PaaS providers. Developers may now concentrate on writing code and creating useful applications rather than managing the infrastructure.

Software as a Service (SaaS): SaaS is a subscription-based method of delivering software applications via the internet. Users no longer require local installs or maintenance because they may access these programmes using a web browser. All facets of the software, including infrastructure, upkeep, upgrades, and security, are managed by SaaS providers.

Q.6 What are the different data types used in cloud computing?

Ans. There is an ample amount of data type in cloud computing. They are emails, contracts, images, blogs etc. As we know that data is increasing day by day so it is needed for new data types to store these new data. For an instance, if a person wants to store video then you need a new data type.

Q.7 What are the common storage of PaaS architecture?

Ans. Cloud Controller:

  • Automatically creates the virtual machines and containers.
  • Deploys applications
  • Connects to services
  • Automatically scales ups and downs

Storage Services:

  • Object
  • NoSQL
  • Relational
  • Block Storage

Applications store state in storage services:

  • Simple to scale applications
  • Easier recovery from failure.

Q.8 What is a Private cloud?

Ans. Private cloud is limited to only a few users and provides maximum security. It is fully operational and can be owned, utilized, operated, and restricted to an only limited organization. Many organizations are preferring private cloud as the security is enhanced in it.

Q.9 What is a Public cloud?

Ans. The public cloud is used among many people and it can be used for deployment. The major focus of the public cloud is the application, infrastructure, and providing platforms to various markets.

Q.10 What are Hybrid clouds?

Ans. Hybrid clouds are made up of both public clouds and private clouds. It is preferred over both the clouds because it applies the most robust approach to implement cloud architecture. The hybrid cloud has features and performance of both private and public cloud.

It has an important feature where the cloud can be created by an organization and the control of it can be given to some other organization.

Ans. It is also a layer in cloud architecture. Platform as a Service is responsible to provide complete virtualization of the infrastructure layer, make it look like a single server and invisible for the outside world.

Q.15 What is the difference in cloud computing and Mobile Cloud computing?

Ans. Mobile cloud computing and cloud computing has the same concept. The cloud computing becomes active when switched from the mobile.

Moreover, most of the tasks can be performed with the help of mobile. These applications run on the mobile server and provide rights to the user to access and manage storage.

Q.16 What are the security aspects provided with the cloud?

Ans. There are 3 types of Cloud Computing Security:

  • Identity Management: It authorizes the application services.
  • Access Control: The user needs permission so that they can control the access of another user who is entering into the cloud environment.
  • Authentication and Authorization: Allows only the authorized and authenticated the user only to access the data and applications

Q.17  What are system integrators in Cloud Computing?

Ans. The system integrator provides the strategy of the complicated process used to design a cloud platform. The integrator provides information about the data centre creation.

Integrator allows creating more accurate hybrid and private cloud network, as integrators have all the knowledge about the data centre creation.

Q.18 What is “EUCALYPTUS” stands for?

Ans. “EUCALYPTUS” is Elastic Utility Computing Architecture which is used for linking the Programs to Useful Systems”

Q.19 Explain what is the use of “EUCALYPTUS” in cloud computing?

Ans. EUCALYPTUS has an open source software infrastructure in cloud computing. It is used to add clusters in cloud computing platform.

With the help of EUCALYPTUS public, private, and hybrid cloud can be built. It can produce it’s own data centres. Moreover, it can allow you to use its functionality to many other organizations.
