Q&A

• Q1) Are there any computing power limitations for Amazon Athena?

  • Athena

    • Serverless data query engine

    • Open Source

  • No computing power limitations

  • Best practices are in AWS Blog

    • ex) Compression etc.

• Q2) We're planning to build a web service for UK and German users soon. EC2 should obviously be in those regions, but should we also put RDS that was originally managed in US region into UK and German regions? It seems right to separate them, but there's internal opinion to just use US region RDS for management reasons.

  • Basically, it's common to place server and DB server in the same region

  • For European services, there may be personal information storage issues (GDPR), so it's recommended to place RDS in European regions

  • Amazon Aurora has added global database features to address problems, but it's good to choose considering latency issues and security concerns.

• Q3) We're using DocumentDB in Seoul region - can we expand to other regions because of global service?

  • DocumentDB snapshots cannot yet be copied to other regions

  • Amazon DynamoDB provides global table cross and regional replication

  • Amazon Aurora also provides global data service

  • Other DBs have difficulty supporting global services, so keep this in mind
