| Question | Answer |
| Bucket | Identify where an objects belons, Are a flat object store, All S3 objects must reside within a Bucket |
| Prefix | Name of characters before an objects name, Groups objects together with the same prefix in their key name. Example : bucketname/myprefix/objectname.png |
| Objects | often thought of as files,can contain any data usually bytes in specif order |
| key | Unique name and path to an object in S3,Excludes the bucket name |
| Value | Literal characters that correspond to a key example Key :Name Value: Tom |
| Version id | Stores multiplies copies of an objects using same object name, Each copy has a unique version ID, |
| Metadata | Default last modified date,Key-value pairs that describe an object,Custom metadata can be specified when object is stored |
| S3 storages classes | standard, intelligent-tiering, standard Infrequent Access, One zone infrequent access, Glacier, Glacier Deep Archive |
| S3 Standard | Original and most popular storage class, Scenarios where you will be accessing an object often, replicates three different physical Availability Zones. |
| S3 Intelligent Tiering | Automatically shifts object in and out of standard and stantard IA classes, Objects that are not request for 30+ days will transition into Standard IA |
| S3 standard-IA | Minimum storage time 30 days, Meant for infrequently accessed objects,128 KB per object size minimun |
| S3 one zone-IA | Stored in a single AZ chosen by S3,Minimum storage 30 days,As a durable as s3 standard but less resilient. |
| S3 Glacier | Uses backend storage provide by amazon S3 , object accessible via the S3 API,for cold workloads,object are not available for real time access. |
| S3 glacier deep archive | cold workloads not real time access, range of few minutes to 12 hours,Cheapest option for sotarage in the cloud,MSP 180 days |
| Versioning | keep a copy of the object using version id,once versioning is enabled every new object gets a version ID |
| Server access logging | Provides detailed records for the request made to a bucket, reviewing access log information for security and access audits |
| Static website hosting | allows website hosting on S3, not support server side scripting. |
| Object Level loggin | this allow AWS Cloudtrail to log data events for object, CloudTrail supports data events |
| Default encryption | Ensure that the customers data is encrypted at rest. |
| Object lock | lock object in place until a specific date |
| tags | uses tags to organize resource costs on the costs allocation report. |
| Transfer acceleration | Takes advantage of amazon cloudfront globally distributed edge location |
| Lifecycle | Automatically transition object into a less expensive storage class, no run in real time,delete and expire object after a number of days |
| Replication | Automatically replicate all new objects added to a bucket to another bucket, S3 Replication Time Control help costumers meet compliance requirements for data replication |
| Analyze storage access patterns | To help decide when to transition the right data to the right storage class |
| Metrics | Allow customers to see the size of their bucket and track the total numbers of objects in a bucket |
| Metrics | paid CloudWatch metrics to view how many request their buckets received in a given time period |
| inventory | Provides daily or weekly report of all objects in an S3 bucket, Inventory reports are not recommended for bucket with billions of objects because report generation will be delayed |
| S3 Batch Operations | set a job to execute batch operations on list of S3 objects contained in a manifest object, jobs must run within 30 days and are deleted 90 days after completion or failure |
| The manifiest Object | Can be an S3 inventory report or a list of objects you generate |
| Access Points | Simplify access control for large, shared, multi tenant bucket, |
| S3 Select | Can run SQL queries in place against CSV and JSON objects, its not necessary to download an object and then query.is possible to affload comnpute resources to S3 |
| Block Public Access | Public Access is granted through (ACLS,Bucket Policies,Acces Point or combination. |
| Comon Limits 1 | Do not have hard limmit for the numbers of request, not limmit to amount of data or object you can put into a Bucket.Bucket name 3 to 63 characters, number for default of bucket per account is 100 but the hard limmit is 1000. |
| Comon Limits 2 | 100 event Notification and 1000 lifecycle rules per bucket,Bucket policies are limmit to 20 KB, Maximum object size is 5TB, Maximun http put request zise is 5 GB |
