AWS S3 복제를 사용하면 데이터 중복, 규정 준수 및 재해 복구와 같은 다양한 목적을 위해 동일하거나 다른 AWS 리전에 있는 버킷 간에 객체를 복제할 수 있습니다. AWS S3에서 사용할 수 있는 복제 유형에는 CRR(Cross-Region Replication)과 SRR(Same-Region Replication)의 두 가지 유형이 있습니다.

CRR(Cross-Region Replication)은 서로 다른 AWS 리전의 버킷 간에 객체를 복제하는 데 사용됩니다. CRR은 버킷의 모든 객체 또는 접두사 또는 태그를 기반으로 객체의 하위 집합을 복제할 수 있습니다. CRR은 여러 대상 버킷에 대한 복제를 지원하며 재해 복구 및 데이터 지역성에 사용할 수 있습니다.

동일 리전 복제(SRR)는 동일한 AWS 리전의 버킷 간에 객체를 복제하는 데 사용됩니다. SRR은 버킷의 모든 객체 또는 접두사 또는 태그를 기반으로 객체의 하위 집합을 복제할 수 있습니다. SRR은 데이터 중복, 규정 준수 및 고가용성을 위해 사용할 수 있습니다.

CRR과 SRR의 주요 차이점은 복제 대상입니다. CRR은 서로 다른 AWS 지역의 버킷에 객체를 복제하고 SRR은 동일한 AWS 지역의 버킷에 객체를 복제합니다. 이 차이는 각 복제 유형의 사용 사례에 영향을 미칩니다.

CRR은 재해 복구 및 데이터 지역성이 필요한 조직에 적합합니다. 개체를 다른 지역의 버킷에 복제함으로써 조직은 지역 중단이 발생한 경우에도 데이터를 사용할 수 있도록 보장할 수 있습니다. CRR은 데이터를 특정 지역에 저장해야 한다는 규정 요구 사항을 준수하는 데에도 사용할 수 있습니다.

반면 SRR은 데이터 중복성과 규정 준수가 필요한 조직에 적합합니다. 개체를 동일한 지역의 버킷에 복제함으로써 조직은 서비스 중단이 있거나 버킷을 사용할 수 없게 되더라도 데이터를 사용할 수 있도록 보장할 수 있습니다. SRR은 또한 데이터를 여러 위치에 저장해야 한다는 규정 요구 사항을 준수하는 데 사용할 수 있습니다.

요약하면 CRR과 SRR은 모두 AWS S3에서 데이터 관리를 위한 중요한 도구입니다. CRR은 재해 복구 및 데이터 지역성에 사용되는 반면 SRR은 데이터 중복 및 규정 준수에 사용됩니다. CRR과 SRR 사이의 선택은 조직의 특정 요구 사항과 요구 사항에 따라 다릅니다.

 

AWS S3 replication allows you to replicate objects between buckets in the same or different AWS regions for various purposes, such as data redundancy, compliance, and disaster recovery. There are two types of replication available in AWS S3: Cross-Region Replication (CRR) and Same-Region Replication (SRR).

CrossRegion Replication (CRR) is used to replicate objects between buckets in different AWS regions. CRR can replicate all objects in a bucket or just a subset of objects based on prefix or tags. CRR supports replication to multiple destination buckets and can be used for disaster recovery and data locality.

SameRegion Replication (SRR) is used to replicate objects between buckets in the same AWS region. SRR can replicate all objects in a bucket or just a subset of objects based on prefix or tags. SRR can be used for data redundancy, compliance, and high availability.

The main difference between CRR and SRR is the destination of replication. CRR replicates objects to buckets in different AWS regions, while SRR replicates objects to buckets in the same AWS region. This difference affects the use cases of each replication type.

CRR is suitable for organizations that require disaster recovery and data locality. By replicating objects to buckets in different regions, organizations can ensure that their data is available even in the event of a regional outage. CRR can also be used to comply with regulatory requirements that mandate data must be stored in specific geographic regions.

SRR, on the other hand, is suitable for organizations that require data redundancy and compliance. By replicating objects to buckets in the same region, organizations can ensure that their data is available even if there is a service disruption or if a bucket becomes unavailable. SRR can also be used to comply with regulatory requirements that mandate data must be stored in multiple locations.

In summary, CRR and SRR are both important tools for data management in AWS S3. CRR is used for disaster recovery and data locality, while SRR is used for data redundancy and compliance. The choice between CRR and SRR depends on the organization's specific needs and requirements.
