Guide to Amazon S3 Replication
What is Amazon S3 Replication?
Amazon S3 Replication is a feature in AWS that automatically replicates (copies) objects across multiple S3 buckets for data redundancy or quicker access to data in diverse geographical regions. It increases business efficiency by ensuring data availability and durability.
Why is it important?
The importance of S3 Replication lies in its capacity to:
1. Safeguard against accidental deletions, or failures.
2. Comply with regulatory standards by maintaining copies of data in different locations.
3. Enhance performance by serving data closer to the users' location.
How does it work?
S3 Replication works by setting up rules in the S3 management console or through AWS SDKs to specify the source and destination buckets. AWS then takes care of replicating newly uploaded objects automatically.
Exam Tips: Answering Questions on S3 Replication
For successful answers in an S3 Replication exam, remember the key points:
1. S3 Replication is asynchronous and only replicates new objects by default.
2. Its cost includes data transfer and storage cost of the replicated data.
3. S3 Replication does not replicate existing objects unless the replication configuration is changed to replicate existing objects.
4. Versioning must be enabled on both the source and destination buckets for replication to happen.
How to set up S3 Replication:
1. Enable versioning on both source and destination buckets.
2. Create a replication rule on the source bucket, specifying the destination bucket and IAM role to grant Amazon S3 the permissions.
3. Optionally, you can select filters to replicate specific objects.
4. Amazon S3 now automatically replicates new objects to the destination bucket.

S3 Replication practice test
S3 Replication allows automatic, asynchronous copying of objects across buckets. This can provide redundancy, improve access latency for geographically distributed applications, and meet compliance requirements. Amazon S3 supports several types of replication, including Same-Region Replication, Cross-Region Replication, and Multi-Destination Replication. Replication can be configured at the bucket or object level, with optional filtering based on prefixes or object tags.
