Copy object or file to S3 bucket.
aws s3 cp filename.ext s3://bucketname/ --profile your-profile |
aws s3 cp filename.ext s3://bucketname/ --profile your-profile
To make it publicly available, run this command.
aws s3api put-object-acl \ --bucket bucket-name \ --key filename.ext \ --acl public-read \ --profile your-profile |
aws s3api put-object-acl \ --bucket bucket-name \ --key filename.ext \ --acl public-read \ --profile your-profile
When changing machine types, you may be asked to enable the latest ENA driver for Enhanced Network Support on an Amazon EC2 instance. There are several instructions depending on the Linux OS flavor. Here are the instructions to enable. In some cases, you may need to rebuild the kernel module. To verify that the ena module is installed, use the modinfo command as shown in the following example.
modinfo ena |
modinfo ena
You also may have to enable the enhanced networking attribute on the instance.
aws ec2 modify-instance-attribute --instance-id instance_id --ena-support |
aws ec2 modify-instance-attribute --instance-id instance_id --ena-support
Just like in S3, you can have to up to 92% in savings if you use Infrequent Access or IA with AWS EFS (Elastic File Storage). You can create a lifecycle policy to move data from standard storage to infrequent access. Files that are not being used after x number of days are then moved to Infrequent Access. The downside is, the data in IA do not count towards gaining burst credits. You will need to keep a certain amount of standard storage to prevent depleting your burst credits.
aws efs put-lifecycle-configuration \ --file-system-id fs-xxxxxxxx \ --lifecycle-policies TransitionToIA=AFTER_30_DAYS \ --region us-east-1 |
aws efs put-lifecycle-configuration \ --file-system-id fs-xxxxxxxx \ --lifecycle-policies TransitionToIA=AFTER_30_DAYS \ --region us-east-1
