Q

Which EBS volume dependent on the life of the EC2 instance for aws?

STOP EC2 KEEP VOLUME ROOT/WINDOWS

A

In Amazon Web Services (AWS), Elastic Block Store (EBS) volumes are used as block-level storage devices that you can attach to your Amazon Elastic Compute Cloud (EC2) instances. There are two types of EBS volumes in terms of their lifecycle dependency on EC2 instances:

Root EBS Volumes:

The root EBS volume is the primary storage device for your EC2 instance and contains the operating system.
By default, the root EBS volume is terminated when the associated EC2 instance is terminated.
If you stop an EC2 instance (as opposed to terminating it), the root EBS volume persists, and you can restart the instance later. However, you are still billed for the storage of the root EBS volume.

Q

Which EBS volume dependent on the life of the EC2 instance for aws? 2

NON ROUTE STAY DETACH WITHOUT TERMINATION OF VOLUME

A

Additional (Non-Root) EBS Volumes:
You can also attach additional EBS volumes to your EC2 instances to provide additional storage space.
Unlike the root EBS volume, additional EBS volumes are not automatically terminated when the associated EC2 instance is terminated. They persist as separate resources.
You can detach additional EBS volumes from an EC2 instance without terminating the instance. This allows you to preserve the data on the volume or attach it to another instance.

Bucket names are globally unique within Amazon S3, making them global identifiers.

29
Q

What are the 6 storage classes, and when might you select to use each one? S3

A

Standard:
Use Case: Frequently accessed data where low latency and high throughput are essential.
Benefits: Durability of 99.999999999% (11 9’s), designed for 99.99% availability.

Intelligent-Tiering:
Use Case: Data with unknown or changing access patterns.
Benefits: Automatically moves objects between two access tiers based on changing access patterns. It has the same durability and availability as Standard.

One Zone-Infrequent Access (One Zone-IA):
Use Case: Infrequently accessed data that can be recreated if lost.
Benefits: Lower cost compared to Standard and IA classes but stores data in a single availability zone.

Glacier:
Use Case: Long-term archival of data where retrieval times of several hours are acceptable.
Benefits: Very low cost, designed for data archiving with a retrieval time measured in hours.

Glacier Deep Archive:
Use Case: Long-term archival of data where retrieval times of 12 hours or more are acceptable.
Benefits: Lowest cost storage class, designed for archiving with infrequent access.

Reduced Redundancy Storage (RRS) - Deprecated:
Use Case: Non-critical, reproducible data.
Note: RRS has been deprecated, and AWS recommends using Standard or Intelligent-Tiering for similar durability but lower costs.

33
Q

How does Amazon S3 Standard-Infrequent Access differ from Amazon S3 One Zone-Infrequent Access? Why would you pick one over the other to use?

STIA MAZ 11 9’S / 1ZONE IA DECREASE COST DECREASE 119’S

A

Standard-IA stores data across multiple availability zones for high durability, while One Zone-IA stores data in a single availability zone, reducing cost but with lower durability. Use cases depend on redundancy requirements.

34

All 6 of the storage classes provide 11 nines of durability, but what is the availability of each storage class?

A

The availability varies across storage classes. Standard, IA, One Zone-IA, Glacier, and Glacier Deep Archive provide 99.99%, while Intelligent-Tiering offers 99.9% availability. Standard: Designed for frequently accessed data. It provides low latency and high throughput.

Intelligent-Tiering: Automatically moves objects between two access tiers (frequent and infrequent access) based on changing access patterns.

One Zone-Infrequent Access (One Zone-IA): Stores data in a single availability zone, providing a cost-effective solution for infrequently accessed data.

Glacier: Suitable for archiving data for long-term retention at a lower cost. Data retrieval times can be longer compared to other storage classes.

Glacier Deep Archive: The lowest-cost storage class, designed for archiving large amounts of data that rarely need to be retrieved.
