Cloud Interview Questions and Answers
Question - 31 : - What is the Public Cloud?
Answer - 31 : -
Be it a public or private cloud, the primary objective is to deliver internet services. Unlike a private cloud, public cloud services are third-party applications that can be used by anybody who wants to access them. The service may be free or be sold on demand.
Public clouds are open to people for use and deployment. For example, Google and Amazon, etc. The public clouds focus on a few layers like cloud application, providing infrastructure, and providing platform markets.
Question - 32 : - What are Hybrid Clouds?
Answer - 32 : -
A hybrid cloud is a cloud computing environment where we can use the services available to us locally and use third-party private services and public services to meet the demand. By allowing workloads to move between private and public clouds as computing needs and costs change, a hybrid cloud gives businesses greater flexibility and more data deployment options.
Hybrid clouds are a combination of public clouds and private clouds. It is preferred over both clouds because it applies the most robust approach to implementing cloud architecture. It includes the functionalities and features of both worlds. It allows organizations to create their cloud and give control over someone else as well.
Question - 33 : - What is the difference between cloud computing and mobile computing?
Answer - 33 : -
Cloud Computing is when you store your files and folders in a “cloud” on the Internet. This will allow you to access all your files and folders wherever you are in the world– but you do need a physical device with Internet access.
Mobile computing is taking a physical device with you, and this could be a laptop or mobile phone, or some device. Mobile computing and cloud computing are somewhat analogous, and mobile computing uses the concept of cloud computing. Cloud computing provides the users with the data they require. In contrast, applications run on the remote server in mobile computing and give the user access to storage and managing the data.
Question - 34 : - What is the difference between Scalability and Elasticity?
Answer - 34 : -
Scalability is a characteristic of cloud computing that is used to handle the increasing workload by increasing the proportion of resource capacity. By using scalability, the architecture provides on-demand resources if the traffic is raising the requirement.
Whereas, Elasticity is a characteristic that dynamically provides the concept of commissioning and decommissioning a large amount of resource capacity. It is measured by the speed at which the resources are on demand and the usage of the resources.
Question - 35 : - What are the security benefits of cloud computing?
Answer - 35 : -
Complete protection against DDoS: Distributed Denial of Service attacks have become very common and are attacking the cloud data of companies. So the cloud computing security ensures restricting traffic to the server, and traffic that can threaten the company and its data is thus averted.
Data security: As data develops, data breaching becomes a significant issue, and the servers become soft targets. The security solution of cloud data helps protect sensitive information and helps the data stay secure against a third party.
Flexibility feature: Cloud offers flexibility, and this makes it popular. The user has the flexibility to avoid server crashing in case of excess traffic. When the high traffic is over, the user can scale back to reduce the cost.
Cloud computing authorizes the application server, which is used in identity management. It provides permissions to the users to control the access of another user who is entering the cloud environment.
Question - 36 : - What is the usage of utility computing?
Answer - 36 : -
Utility computing, or The Computer Utility, is a service provisioning model. A service provider makes computing resources and infrastructure management available to the customer and charges them for specific usage rather than a flat rate.
Utility computing is a plug-in managed by an organization that decides what type of cloud service has to be deployed. It facilitates users to pay only for what they use.
Question - 37 : - Explain Security management regarding Cloud Computing.
Answer - 37 : -
– Identity management access provides the authorization of application services
– Access control permission is given to the users to have complete controlling access to another user who is entering into the cloud environment
– Authentication and Authorization provide access to authorized and authenticated users only to access the data and applications
Question - 38 : - How would you secure data for transport in the cloud?
Answer - 38 : -
This is a frequently asked question. Don’t forget to dive in more in-depth on this topic.
When transporting data in a cloud computing environment, keep two things in mind: Make sure that no one can intercept your data as it moves from point A to point B in the cloud, and make sure that no data leaks (malicious or otherwise) from any storage in the cloud.
A virtual private network (VPN) is one way to secure data while transported in a cloud. A VPN converts the public network to a private network instead. A well-designed VPN will incorporate two things:
A firewall will be a barrier between the public and any private network.
Encryption protects your sensitive data from hackers; only the computer you send it to should have the key to decode the data.
Check that there is no data leak with the encryption key implemented with the data you send while moving from point A to point B in a cloud.
Question - 39 : - What do you mean by encapsulation in cloud computing?
Answer - 39 : -
A container is a packaged software code along with all of its dependencies so that it can run consistently across clouds and on-premises. This packaging up of code is often called encapsulation. Encapsulating code is important for developers as they don’t have to develop code based on each individual environment.
Question - 40 : - What do you mean by Rate Limiting?
Answer - 40 : -
Rate Limiting is a way to limit the network traffic. Rate limiting runs within the app rather than the server. It typically tracks the IP addresses and the time between each request.
It can eliminate certain suspicious and malicious activities. Bots that impact a website can also be stopped by Rate Limiting. This protects against API overuse which is important to prevent.
