In this post you will learn frequently asked Amazon web Services(AWS) Interview Questions and Answers.The following are the best AWS interview Questions.
1. What is AWS?
Ans: AWS (Amazon Web Services) is a platform to provide secure cloud services, database storage, offerings to compute power, content delivery, and other services to help business level and develop.
2. What are the Key Components of AWS?
Ans:
The fundamental elements of AWS are:
Route 53: A DNS web service
Easy E-mail Service: It permits addressing e-mail utilizing RESTFUL API request or through normal SMTP
Identity and Access Management: It gives heightened protection and identity control for your AWS account
Simple Storage Device or (S3): It is warehouse equipment and the well-known widely utilized AWS service
Elastic Compute Cloud (EC2): It affords on-demand computing sources for hosting purposes. It is extremely valuable in trouble of variable workloads
Elastic Block Store (EBS): It presents persistent storage masses that connect to EC2 to enable you to endure data beyond the lifespan of a particular EC2
Cloud Watch: To observe AWS sources, It permits managers to inspect and obtain key Additionally, one can produce a notification alert in the state of crisis.
3. Explain how the buffer is used in Amazon web services?
Ans: The buffer is used to make the system more robust to manage traffic or load by synchronizing different component. Usually, components receive and process the requests in an unbalanced way, With the help of buffer, the components will be balanced and will work at the same speed to provide faster services.
4. What Are The Components Involved In Amazon Web Services?
Ans:
here are 4 components involved and are as below.
Amazon S3: with this, one can retrieve the key information which are occupied in creating cloud structural design and amount of produced information also can be stored in this component that is the consequence of the key specified.
Amazon EC2 instance: helpful to run a large distributed system on the Hadoop cluster. Automatic parallelization and job scheduling can be achieved by this component.
Amazon SQS: this component acts as a mediator between different controllers. Also worn for cushioning requirements those are obtained by the manager of Amazon.
Amazon SimpleDB: helps in storing the transitional position log and the errands executed by the consumers
5. What Is An Ami ? How Do I Build One?
Answer :
AMI holds for Amazon Machine Image. It is efficiently a snap of the source filesystem. Products appliance servers have a bio that shows the master drive report of the initial slice on a disk. A disk form though can lie anyplace physically on a disc, so Linux can boot from an absolute position on the EBS warehouse interface.
Create a unique AMI at beginning rotating up and instance from a granted AMI. Later uniting combinations and components as needed. Comprise wary of setting delicate data over an AMI (learn salesforce online). For instance, your way credentials should be joined to an instance later spinup. Among a database, mount an external volume that carries your MySQL data next spinup actually enough.
6. Distinguish between scalability and flexibility?
Answers:
Scalability:The ability of any scheme to intensify the tasks on its hardware resources to hold the inconsistency in command is called as scalability.
Flexibility:The aptitude of a schema that augments the task on the hardware property is known as flexibility.
AWS provides several configuration solutions for the AWS flexibility, scalability, availability and management.
7.List the features of Amazon cloud search?
Answer:
The Amazon cloud search features:
Range searches
Prefix Searches
Boolean Searches
Entire text search with language specific text processing
Highlighting
AutoComplete advice
Faceting term boosting
8.What Is S3? What Is It Used For? Should Encryption Be Used?
Answer :
S3 stands for Simple Storage Service. You can think of it like FTP storage, where you can move files to and from there, but not mount it like a filesystem. AWS automatically puts your snapshots there, as well as AMIs there. Encryption should be considered for sensitive data, as S3 is a proprietary technology developed by Amazon themselves, and as yet unproven vis-a-vis a security standpoint.
9. What Is Auto-scaling? How Does It Work?
Answer :
Autoscaling is a feature of AWS which allows you to configure and automatically provision and spin up new instances without the need for your intervention.
You do this by setting thresholds and metrics to monitor. When those thresholds are crossed, a new instance of your choosing will be spun up, configured, and rolled into the load balancer pool. Voila, you’ve scaled horizontally without any operator intervention!
10. What Automation Tools Can I Use To Spin Up Servers?
Answer :
The most obvious way is to roll-your-own scripts, and use the AWS API tools. Such scripts could be written in bash, Perl or another language or your choice.
The next option is to use a configuration management and provisioning tools like puppet or better it’s successor Opscode Chef.You might also look towards a tool like Scalr. Lastly, you can go with a managed solution such as Rightscale.
