Question

What are two forms of storage that you can use to persist data for your EC2?

1) EBS (Elastic Block Store)
2) Instance Store
3) S3 (Simple Storage Service)
4) RDS (Relational Database Service)

Answer 1

EBS (Elastic Block Store) and Instance Store are two storage options for persisting data on EC2 instances. EBS is a network-attached storage with high availability, while Instance Store provides temporary, high-performance storage.

Step-by-step explanation:

There are multiple storage options available for persisting data on Amazon EC2 instances. Two forms of storage are:

• EBS (Elastic Block Store): EBS provides block-level storage volumes for use with EC2 instances. Volumes are network-attached and persist independently from the life of an instance. They offer high-availability and durability, and they can be attached or detached from EC2 instances as needed. Additionally, EBS volumes offer features like snapshot backups and the ability to provision IOPS for performance needs.
• Instance Store: Instance Store provides temporary block-level storage directly attached to the host computer for an EC2 instance. The data on an instance store volume is lost if the instance is stopped, terminated, or if the underlying host fails. Instance store volumes can be ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other transient content.

While S3 (Simple Storage Service) and RDS (Relational Database Service) are also utilized within AWS to persist data, they are not considered direct storage options for EC2 instances in the same way as EBS and Instance Store.
