![]() What AWS region should you use for the S3 bucket? Question 4: What AWS region should you use for the S3 bucket? Use case In general, the price is lower the longer the recovery time is.įor production files, use Intelligent Tiering.įor logs, use S3 Standard for up to 7 days, and then let a lifecycle rule transition the logs to S3 One Zone – Infrequent Access or Glacier Flexible Retrieval. The choice depends on how quickly you require the files to be restored. Use S3 Intelligent Tiering for optimizing the storage costs. Question 3: What S3 storage class should you use? Use caseĭata lakes have usually unpredictable access patterns. Set up AWS CloudFront to serve the static files from S3. Whenever possible use compression and do not archive duplicate files. Use compression and do not backup duplicate files. Whenever possible use incremental backup. Use compressed binary files, rather than csv files whenever possible – we recommend using compressed Parquet files. Question 2: What data should you store in AWS S3? Use case The logs for cloud-native applications should expire (deleted) after a certain number of months. If you use incremental backups, ensure you expire all files in the one incremental backup series. Set up an S3 lifecycle rule to expire (delete) all backups / archives older than the required number of years. Very rarely you need to access old backups or archives, though Compliance may require keeping these for a certain number of years. Identify those datasets which are no longer useful after a certain number of years and either S3 tag them or set up an S3 lifecycle rule to expire (delete) such datasets identified by a prefix or tag after a certain number of years. While machine learning / artificial intelligence models are better calibrated with larger data sets, for some models older data sets are no longer useful since the underlying patterns have changed. Question 1: How long do you need to keep old data? Use case To make the most of the AWS S3 service, be aware of the following questions. In general, AWS S3 is used for these use cases: does not provide a hierarchical (tree) object storage – one can emulate directories with prefixes – data in S3 is organized in S3 buckets with a single level of hierarchy.does not allow appending additional data to an object – each object has to be updated in full. ![]() Amazon S3 is an object storage managed service designed for storing an unlimited amount of data.
