Cloud Computing Interview Questions and Answers

Someone has rightly said that interviews are more stressful than the job is. Many times we just wish that we do not have to do that entire one on one session. Do not worry, we are here to scoop you out of the stress that you might be going through for your interview related to Cloud Computing. We have compiled an article for you that will help you nail your interview like a pro.

In the easiest way to explain, cloud computing is nothing but the delivery of computing services such as servers, databases, storage, software, analytics, networking and more over the Internet cloud (“the Cloud”). Companies that offer these computing services are known as cloud providers and usually, charge for these cloud computing services based on the criteria of using just the way how you as an individual is charged for water or electricity at their premises.

Most of the cloud computing services are classified into three broad categories namely:

• Infrastructure As A Service (Iaas),
• Platform As A Service (Paas), And
• Software As A Service (Saas).
• These services are sometimes called the “cloud computing stack”, for the reason that they are built on top of one another.

Cloud Computing Interview Questions And Answers

For the professionals who are looking to attend Cloud Computing interview recently, here are some of the most popular interview questions and answers that will help you in the right way. Over here, we have included the top frequently asked questions with answers to help the freshers as well as the experienced professionals in the field.

Cloud Computing Interview Questions And Answers For Freshers

Q1). What is cloud computing?

Cloud computing is a new age computer technology that is internet based. It is the next generation technology that utilizes the web-based clouds to provide the services whenever and wherever the users need it.

Q2). What are the benefits of cloud computing?

The major advantages of cloud computing are:

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

Q3). What is a cloud?

A cloud is an amalgamation of hardware, network, services, storage, and interfaces that aid in delivering computing as a service. It has three users :

• End users
• Business management users
• cloud service provider

Q4). Mention platforms which are used for large-scale cloud computing?

Apache Hadoop – Apache Hadoop is known to be an open source software platform for dispersed storage and distributed dispensation of huge data sets on computer bundles built from the product hardware.  Hadoop services supply for data storage, data access, data processing, data governance, operations and security.

MapReduce – Google has definitely revolutionized analysis of large-scale datasets with this great platform. It enables the processing of massive datasets using cloud sources and other commodity hardware. It provides for fault forbearance and clear sociability at the software level.

Q5). What is PaaS?

PaaS is one of the categories of cloud computing that provides a platform and environment to let the developers build apps and services over the internet. PaaS services are hosted in the cloud and are accessed by users simply through their web browsers.

Q6). What is Saas?

Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them accessible to customers over the Internet.

Q7). What is Iaas?

Infrastructure as a service (IaaS) is a form of cloud computing that provides for virtualized computing resources over the internet itself. 

Q8). What is Caas?

Communications as a Service (CaaS) is an outsourced scheme interactions solution that can be leased from a single vendor over the web.

Q9). What are the basic characteristics of cloud computing? 

• There are four basic characteristics of cloud computing: Self-service provisioning and automatic de-provisioning.
• Elasticity and scalability.
• Billing self-service based usage model. Standardized interfaces.

Q10). What are the essential things that must be followed before going to cloud computing platform

The essential things that must be followed are-

• Compliance issues
• Data storage types
• Maintaining data integrity in the cloud
• Ensuring availability and access
• Protection from loss of data
• Business continuity
• Uptime – reduction of downtime 

Cloud Computing Interview Questions And Answers For Experienced

Q11). What are the different layers that define cloud architecture?

The different layers used by cloud architecture are

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

Q12). Mention About Applications Now A Days?

Topmost cloud computing apps include google docs which are very fast and secure. There is also an extended mobile version of google docs app so that you can have access to your data from your smartphone. Pixlr and Phoenix, jaycut also are some of the apps used for cloud computing.

Q13). What are the types of data used in cloud computing?

There are many different data types used in cloud computing like emails, images, contracts, blogs etc. As it is a known fact that data is increasing day by day so it is essential for the new data types to securely store these new data types. For an instance, if you wish to store video then you need a new data type.

Q14). How can a company benefit from cloud computing?

A company can benefit from cloud computing in the following ways-

• More secure data backup and data storage
• Software as a service (SaaS)
• Take advantage of powerful server capabilities without hardware investment
• Platform and OS agnostic
• Better positioning for growth and scale
• Increased productivity
• Sandboxing and virtualization capabilities
• Cost-effectivenes 

Q15). How can you best secure data for transportation to the cloud?

First of all make sure that your data cannot be blocked as it moves into the cloud storage by making sure that there are absolutely no data leaks —malevolent or not, from its cloud storage. This can be easily accomplished by using a secure key.

Q16). What is the Security management in terms of Cloud Computing?

Here are the popular security management processes in terms of cloud computing-

• Identity management- It provides access to the authorization of application services.
• Access control permission- It provides users to have complete controlling access of another user too who is entering into the same cloud environment.
• Authentication and Authorization- It provides access to only the authorized and authenticated personnel to securely access the data and applications.

Q17). Mention what is the difference between elasticity and scalability in cloud computing?

Scalability is a typical characteristic of cloud computing which is used to handle the escalating workload by escalating in proportion amount of resource capacity. By the use of scalability, the architecture provides resources on requirement BA is resources as and when the requirement is being raised by the traffic. On the other hand, Elasticity is a characteristic that provides for the concept of commissioning and decommissioning of thehuge amount of resource capacity dynamically. It is usually measured by the speed by which the resources are coming on demand and the usage of those resources.

Q18). What are Hybrid clouds?

Hybrid clouds are nothing but a combination of public clouds as well as private clouds. It is usually preferred over both the clouds because it applies the most healthy approach to implementation of the cloud architecture. It includes the functionalities as well as the features of both the worlds at the same time. It allows the organizations to design their own cloud and permit them to give the control over to someone else as well.

Q19). What is "EUCALYPTUS" in cloud computing?

EUCALYPTUS is an acronym that stands for Elastic Utility Computing Architecture For Linking Your Program To Useful Systems. It is used to execute clusters in cloud computing platform.

Q20). What is the difference between cloud computing and mobile computing?

Mobile computing and cloud computing are slightly a similar concept. Mobile computing uses the concept of cloud computing. Cloud computing, on the other hand,provides its users with the data which they required while migrating or working in mobile computing for the apps running on the remote server systems and gives the user the access for storage and management of data.
