Users pay for EC2 instances by the hour or second, with no long-term commitments.

Users are charged based on data transfer only.

Users pay a flat monthly fee for EC2 instances.

Users must commit to a minimum usage period of one year.

EBS is used for managing EC2 instance security settings.

The purpose of Elastic Block Store (EBS) in EC2 is to provide persistent block storage for EC2 instances.

EBS is designed for load balancing across multiple EC2 instances.

EBS provides temporary storage for EC2 instances.

The lifecycle of an EC2 instance includes: initializing, active, pausing, paused, shutting-down, and decommissioned.

The lifecycle of an EC2 instance features: booting, operational, suspending, suspended, shutting-down, and removed.

The lifecycle of an EC2 instance consists of: starting, active, halting, halted, shutting-down, and deleted.

The lifecycle of an EC2 instance includes: pending, running, stopping, stopped, shutting-down, and terminated.

Reserved Instances offer cost savings for long-term commitments, while Spot Instances provide cheaper, flexible pricing for short-term use.

Reserved Instances are more flexible than Spot Instances.

Reserved Instances are only available for on-demand pricing.

Spot Instances guarantee availability for all users.

Ignore monitoring and scheduling

Use only on-demand instances

Data is stored on a single device with no backups.

Amazon S3 uses encryption to ensure data safety.

Data is only checked for integrity once a year.

Amazon S3 ensures data durability through data replication across multiple devices and facilities, regular integrity checks, and a distributed architecture.

To manage network traffic for the EC2 instance.

To provide information about the EC2 instance to applications running on it.

To monitor the CPU usage of the EC2 instance.

To store data persistently for the EC2 instance.

EBS snapshots require manual intervention for restoration.

EBS snapshots provide real-time data streaming.

Benefits of using EBS snapshots include data backup, cost efficiency, quick recovery, and incremental storage.

EBS snapshots enhance network security and performance.

Use the S3 Management Console, AWS CLI, or lifecycle policies to change storage classes.

Change storage classes only through AWS Lambda functions.

Use the S3 API to manually copy objects between classes.

Objects can only be transitioned using third-party tools.

IAM automates the deployment of EC2 instances and S3 buckets.

IAM manages access to EC2 and S3 by defining user permissions and roles.

IAM provides encryption for data stored in EC2 and S3.

IAM restricts access to EC2 and S3 by monitoring network traffic.

Select the instance, then click 'Detach Volume' from the options.

Right-click the instance and select 'Stop Instance'.

Select the instance, then choose 'Terminate Instance' from the 'Instance State' menu.

Choose the instance and click 'Reboot Instance' from the menu.

Instance store provides higher durability than EBS, which is temporary and less reliable.

EBS is tied to the lifecycle of the instance, while instance store can be detached and reattached.

Instance store is persistent and can be used across multiple instances, while EBS is ephemeral.

Instance store is ephemeral and tied to the lifecycle of the instance, while EBS is persistent and can be detached and reattached to different instances.
