Question : It is always best way to use AWS root account credentials to access AWS and create new user

: It is always best way to use AWS root account credentials to access AWS and create new user
1. True
2. False

Correct Answer : Get Lastest Questions and Answer :

Exp: Dont use your AWS root account credentials to access AWS, and dont give your credentials to anyone else. Instead, create individual users (using the IAM console, the APIs, or the command line interface) for anyone who needs access to your AWS account. Create an IAM user for yourself as well, give that IAM user administrative privileges, and use that IAM user for all your work.

By creating individual IAM users for people accessing your account, you can give each IAM user a unique set of security credentials. You can also grant different permissions to each IAM user. If necessary, you can change or revoke an IAM users permissions any time. (If you give out your AWS root credentials, it can be difficult to revoke them.)

Exp : Using ElastiCache Redis as an In-Memory Key-Value Store

Note
This topic is based on a Linux stack, but Windows stacks can also use Amazon ElastiCache (ElastiCache). For an example of how of how to use ElastiCache with a Windows instance, see ElastiCache as an ASP.NET Session Store.
You can often improve application server performance by using a caching server to provide an in-memory key-value store for small items of data such as strings. Amazon ElastiCache is an AWS service that makes it easy to provide caching support for your application server, using either the Memcached or Redis caching engines. AWS OpsWorks provides built-in support for Memcached. However, if Redis better suits your requirements, you can customize your stack so that your application servers use ElastiCache Redis.

This topic walks you through basic process of providing ElastiCache Redis caching support for Linux stacks, using a Rails application server as an example. It assumes that you already have an appropriate Ruby on Rails application. For more information on ElastiCache, see What Is Amazon ElastiCache?.

Q: How is Amazon S3 data organized?

Amazon S3 is a simple key-based object store. When you store data, you assign a unique object key that can later be used to retrieve the data. Keys can be any string, and can be constructed to mimic hierarchical attributes.

: When should I use Amazon DynamoDB vs Amazon S3?

Amazon DynamoDB stores structured data, indexed by primary key, and allows low latency read and write access to items ranging from 1 byte up to 400KB. Amazon S3 stores unstructured blobs and suited for storing large objects up to 5 TB. In order to optimize your costs across AWS services, large objects or infrequently accessed data sets should be stored in Amazon S3, while smaller data elements or file pointers (possibly to Amazon S3 objects) are best saved in Amazon DynamoDB.

Q: What types of data structures does DynamoDB support?
DynamoDB supports key-value and document data structures.
Q: What is a key-value store?
A key-value store is a database service that provides support for storing, querying and updating collections of objects that are identified using a key and values that contain the actual content being stored.
