Q1. How can you deploy cloud computing with different models?
Ans. Various models are used for deployment in cloud computing. They are as follows: Private Cloud, Public Cloud, Hybrid Cloud, and Community Cloud.Q2. Can you name some open source cloud computing platform databases?
Ans. The three main open-source cloud computing platform databases are Couch DB, Lucid DB, and Mongo DB. (DB stands for the database)

This is one of the frequently asked cloud security interview questions that you may probably come across during the interview. You should name the cloud computing platform databases that you have worked upon as the interviewer may ask some more questions on those databases.

Q3. Can you differentiate between computing for mobiles and cloud computing?
Ans. Although, both of these use the same concept, yet they differ in some instances. In the case of cloud computing, it is activated via the internet instead of the individual device. This facilitates the user to retrieve data on demand. On the other hand, the mobile runs applications on the remote server and therefore lets the user access the storage and manage accordingly.

Q4. What can a user gain from utility computing?
Ans. The main advantage of utility computing is that a user pays for only what he uses. It is like a plug-in that is managed by the organization which decides on the type of services to be deployed from the cloud.

Q5. Do you know the security laws that are implemented to secure data in the cloud?
Ans. There are a total of five main security laws that are generally implemented. They are:

• Validation of input: The input data is controlled.
• Backup and security: The data is secured and stored and thus controls data breaches.
• Output reconciliation: The data is controlled which is to be reconciled from input to output.
• Processing: The data which is processed correctly and completely I an application, is controlled.

Q6. How is cloud different from traditional data centres?
Ans. The traditional data centres are expensive owing to the factor that the heating of hardware or software. And most of the expenses are spent on the maintenance of the data centres, but this is not the case in cloud computing. In the case of the cloud, the data can be stored easily and does not require as much expense with their maintenance.

Q7. How do you secure your data while transferring to the cloud?
Ans. In order to secure the data while transferring on the cloud, it is to be checked that there is no leakage as such, and therefore encryption key must be implemented with the data that is being sent.

Q8. List the components needed in cloud architecture?
Ans. There are five main components of cloud architecture. They are:

• Cloud storage services
• The speed of the Processor
• Intracloud communications
• Cloud storage services
• Cloud ingress

Q9. What do system integrators do in cloud computing?
Ans. The system integrators of cloud computing provide the strategy of complicated processes that are used in designing a cloud platform. Owing to the fact that integrators have the knowledge of data centre creation, they are likely to help in developing both public and private cloud networks even more accurately.

Q10. Why is a virtualization platform needed in implementing the cloud?
Ans. Virtualization is required in the implementation of the cloud due to the following reasons:

• Cloud operating system
• In order to manage the service policies
• In order to keep the backend level and user level concepts different from each other.

Q11. How is a buffer used in Amazon Web Services?
Ans. A buffer is used to make systems more efficient against the traffic or load. It helps in the synchronization of different components. The buffer helps in maintaining the balance between those components and also makes them work at the same speed in order to get the work done faster.

Q12. What is the Hypervisor in cloud computing?
Ans. A hypervisor is a virtual machine monitor. It helps in the management of virtual machines. Generally, there are two types of hypervisors. They are:

Type 1 – in this case, the guest VM directly runs over the host hardware.

Type 2 – in this case, the guest VM runs over the hardware through a host operating system.

Q13. What are the native AWS Security logging capabilities?
Ans. Most of the AWS services have their logging options. Also, some of them have account level logging, like in AWS CloudTrail, AWS Config, and others. Let’s take a look at two services in specific:

AWS CloudTrail
This is a service that provides a history of the AWS API calls for every account. It lets you perform security analysis, resource change tracking, and compliance auditing of your AWS environment as well. The best part about this service is that it enables you to configure it to send notifications via AWS SNS when new logs are delivered.

AWS Config
This helps you understand the configuration changes that happen in your environment. This service provides an AWS inventory that includes configuration history, configuration change notification, and relationships between AWS resources. It can also be configured to send information via AWS SNS when new logs are delivered.

Q14. What is a DDoS attack, and what services can minimize them?
Ans. DDoS is a cyber-attack in which the perpetrator accesses a website and creates multiple sessions so that the other legitimate users cannot access the service. The native tools that can help you deny the DDoS attacks on your AWS services are:

• AWS Shield
• AWS WAF
• Amazon Route53
• Amazon CloudFront
• ELB
• VPC

Q15. How do you connect multiple sites to a VPC?
Ans. If you have multiple VPN connections, you can provide secure communication between sites using the AWS VPN CloudHub. Here’s a diagram that will show you how to connect various sites to a VPC:

Q16. How can you use AWS WAF in monitoring your AWS applications?
Ans. AWS WAF or AWS Web Application Firewall protects your web applications from web exploitations. It helps you control the traffic flow to your applications. With WAF, you can also create custom rules that block common attack patterns. It can be used for three cases: allow all requests, prevent all requests, and count all requests for a new policy.

Q17. What are the different AWS IAM categories that you can control?
Ans. Using AWS IAM, you can do the following:

• Create and manage IAM users
• Create and manage IAM groups
• Manage the security credentials of the users
• Create and manage policies to grant access to AWS services and resources

Q18. Can you give an example of an IAM policy and a policy summary?
Ans. Here’s an example of an IAM policy.

Q19.What is the difference between Latency Based Routing and Geo DNS?
Ans. The Geo Based DNS routing takes decisions based on the geographic location of the request. Whereas, Latency Based Routing utilizes latency measurements between networks and AWS data centres. Latency Based Routing is used when you want to give your customers the lowest latency possible. On the other hand, Geo Based routing is used when you want to direct the customer to different websites based on the country or region they are browsing from.

Q20. What is the difference between a Domain and a Hosted Zone?
Ans.
Domain
A domain is a collection of data describing a self-contained administrative and technical unit.

Hosted zone
A hosted zone is a container that holds information about how you want to route traffic on the internet for a specific domain.

Q21. How does Amazon Route 53 provide high availability and low latency?
Ans. Here’s how Amazon Route 53 provides the resources in question:

Globally Distributed Servers
Amazon is a global service and consequently has DNS services globally. Any customer creating a query from any part of the world gets to reach a DNS server local to them that provides low latency.

Dependency
Route 53 provides a high level of dependability required by critical applications

Optimal Locations
Route 53 uses a global anycast network to answer queries from the optimal position automatically.

Q22. Can AWS Config aggregate data across different AWS accounts?
Ans. Yes, you can set up AWS Config to deliver configuration updates from different accounts to one S3 bucket, once the appropriate IAM policies are applied to the S3 bucket.

Q23. What happens when one of the resources in a stack cannot be created successfully?
Ans. If the resource in the stack cannot be created, then the CloudFormation automatically rolls back and terminates all the resources that were created in the CloudFormation template. This is a handy feature when you accidentally exceed your limit of Elastic IP addresses or don’t have access to an EC2 AMI.

Q24. What is the use of lifecycle hooks in Autoscaling?
Ans. Lifecycle hooks are used for Auto-scaling to put an additional wait time to a scale-in or a scale-out event.
