Q1. What is auto-scaling?

Ans. Auto-scaling is a feature of AWS which allows you to configure and automatically provision and spin-up new instances without the need for your intervention.

Q2. What are the different types of cloud services?

Q3. What is Amazon S3?

Ans. Amazon S3 (Simple Storage Service) is an object storage with a simple web service interface to store and retrieve any amount of data from anywhere on the web.

Q4. What is SimpleDB?

Ans. It is a structured data store that supports indexing and data queries to both EC2 and S3.

Q5. What is an AMI?

Ans. AMI (Amazon Machine Image) is a snapshot of the root filesystem.

Q6. What is the type of architecture, where half of the workload is on the public load while at the same time half of it is on the local storage?

Ans. Hybrid cloud architecture.

Q7. Can I vertically scale an Amazon instance? How do you do it?

Ans. Yes. Spin up a new larger instance than the one you are running, then pause that instance to detach the root EBS volume from this server and discard. After that, stop the live instance and detach its root volume. Note the unique device ID and attach that root volume to the new server, and start again. This way you will have scaled vertically.

Q8. How can you send a request to Amazon S3?

Ans. You can send a request by using the REST API or the AWS SDK wrapper libraries that wrap the underlying Amazon S3 REST API.

Q9. How many buckets can be created in AWS by default?

Ans. By default, 100 buckets can be created.

Q10. Should encryption be used for S3?

Ans. Encryption should be considered for sensitive data as S3 is a proprietary technology.
