s3 storage class

• storage class will based on file accessing and pricing
• to manage storage class with s3 lifecycle

1. Standard :

• general purpose used for frequently access file
• millisecond to access the file
• webapp, mobile apps, daily used files and automation scrpits …etc

2. s3 Intelligent-Tiering:

• automatically change storage class based on access the file.
• millisecond to access the file

1. Standard-IA

• access the once in a month
• replicas >= 3
• after 30 days only you can change storage class

1. One Zone-IA

• access the once in a month
• back will be one zone
• after 30 days only you can change storage class

1. Glacier Instant Retrieval

• Long-lived archive data accessed once a quarter with instant retrieval in milliseconds
• replicas will >=3
• used for once in a 90 days
• archevied
• after 90 days only you can change storage class

1. Glacier Flexible Retrieval (formerly Glacier)

• Long-lived archive data accessed once a year with retrieval of minutes to hours
• after 90 days only you can change storage class

1. Glacier Deep Archive

• Long-lived archive data accessed less than once a year with retrieval of hours
• cost of storage is very less compare with other storage class
• retrieval will up to 12 hours to access file based on file sizes
• after 180 days only you can change storage class

}

Task:

1. create s3 bucket and enable versioning
2. create lifecycle rule change object store class
   1. after 30 days Standard-IA
   2. after 60 days Glacier Instant
   3. ater 180 days Glacier Deep Archive
