Explanation: Customers may use four mechanisms for controlling access to Amazon S3 resources: Identity and Access Management (IAM) policies, bucket policies, Access Control Lists (ACLs) and
query string authentication. IAM enables organizations with multiple employees to create and manage multiple users under a single AWS account. With IAM policies, companies can grant
IAM users fine-grained control to their Amazon S3 bucket or objects while also retaining full control over everything the users do. With bucket policies, companies can define rules
which apply broadly across all requests to their Amazon S3 resources, such as granting write privileges to a subset of Amazon S3 resources. Customers can also restrict access based
on an aspect of the request, such as HTTP referrer and IP address. With ACLs, customers can grant specific permissions (i.e. READ, WRITE, FULL_CONTROL) to specific users for an
individual bucket or object. With query string authentication, customers can create a URL to an Amazon S3 object which is only valid for a limited time
Amazon S3 provides a simple web services interface that you can use to store and retrieve any amount of data, at any time, from anywhere on the web. Using this web service,
developers can easily build applications that make use of Internet storage. Since Amazon S3 is highly scalable and you only pay for what you use, developers can start small and grow
their application as they wish, with no compromise on performance or reliability. It is designed to be highly flexible: Store any type and amount of data that you want; read the same
piece of data a million times or only for emergency disaster recovery; build a simple FTP application, or a sophisticated web application such as the Amazon.com retail web site.
Amazon S3 frees developers to focus on innovation, not figuring out how to store their data.






Question : You receive a frantic call from a new DBA who accidentally dropped a table containing all your
customers.

when the mistake was made?

Correct Answer : Get Lastest Questions and Answer :
Explanation: Amazon RDS can automatically back up all of your DB instances. You can set the backup retention period when you create a DB instance. If you don't set the
backup retention period, Amazon RDS uses a default period retention period of one day. You can modify the backup retention period; valid values are 0 (for no backup retention) to a
maximum of 35 days. Manual snapshot limits (50 per region) do not apply to automated backups.
Point-In-Time Recovery

In addition to the daily automated backup, Amazon RDS archives database change logs. This enables you to recover your database to any point in time during the backup retention
period, up to the last five minutes of database usage.
Amazon RDS provides two different methods for backing up and restoring your Amazon DB instances: automated backups and DB snapshots. Automated backups automatically back up your DB
instance during a specific, user-definable backup window, and keeps the backups for a limited, user-specified period of time (called the backup retention period); you can later
recover your database to any point in time during that retention period. DB snapshots are user-initiated backups that enable you to back up your DB instance to a known state, and
restore to that specific state at any time. Amazon RDS keeps all DB snapshots until you delete them.







Question : A media company produces new video files on-premises every day with a total size of around
100GBS after compression All files have a size of 1 -2 GB and need to be uploaded to Amazon S3
every night in a fixed time window between 3am and 5am Current upload takes almost 3 hours,
although less than half of the available bandwidth is used.
What step(s) would ensure that the file uploads are able to complete in the allotted time window?
: A media company produces new video files on-premises every day with a total size of around
1. Increase your network bandwidth to provide faster throughput to S3
2. Upload the files in parallel to S3

Correct Answer : Get Lastest Questions and Answer :
Explanation: Amazon S3 is clustered storage service of Amazon. It is designed to make web-scale computing easier. Amazon S3 provides a simple web services interface that
can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast,
inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
For using Amazon services, you'll need your AWS access key identifiers, which AWS assigned you when you created your AWS account. The following are the AWS access key identifiers:
AWS Import/Export should be use as a one time upload not on a regular basis.
