AWS SAA-C02 시험용 간단 정리

• TCP + milliseconds => NLB
• Concurrency => EFS, S3
• DB/App server SMB/NFS => File Gateway
• SMB => File Gateway or FSx
• Common query/reads => caching
• Request/Response message pattern => temporary queue client SQS
• Static front end => S3
• Decouple => SQS
• static dynamic caching / video streaming => CloudFront
• highly accessible storage => S3
• Gateway endpoints + S3 => Free of Charge, reduce load off of DB for read instances workloads
• Save credentials / Database credentials => Secret Manager
• EC2 CPI util at or near => target tracking
• EC2 predictable => scheduled
• WAF + ALB 짝궁
• similar / identical => ElastiCache
• No change + caching => DAX
• Nitro + io1/io2 => 64,000IOPS
• Amazon Inspector => EC2
• NFS file system => EFS
• S3 cross region => new object 부터 적용됨
• Migration, JSON => DataSync
• integration => Storage Gateway
• at rest & in transit encryption => client side encryption
• at rest encryption => server side encryption
• Mamcache => simple, no high availability, no back and restore
• Redis => replication, keep cache, game leaderboard, backup and restore
• Constantly current = EFS
• No changes =/= S3
• No cost between S3 & EC2 in same region
• node to node => cluster placement group
• aging for messages => SLA
• milliseconds response => DynamoDB
• clickstream analysis => Kinesis data firehose / Redshift
• HTTP => CloudFront
• HTTP + non HTTP(TCP/UDP) => Global Accelerator
• Big data processing => EMR
• Layer4 => NLB
• API Gateway + Lambda + DynamoDB 짝궁
• HPC + Linux => FSx for Lustre
• Patching database => Aurora
• 1sec RPO, 1min RTP => Aurora Global DB
• 99% availability => S3
• VPC flow log target => S3 / CloudWatch
• NAT =/= IPv6
• Secure/private connection between AWS services => VPC endpoints
• Gateway endpoints => S3, DynamoDB
• VPC interface => S3
• a static content + accessed by global => CloudFront
• Complicated analytical queries and joins => Redshift
• Direct Connect + VPN(backup) = low latency + low cost(backup)
• Query historical data => Athena
• Near real time streaming data => Kinesis data analytics
• API Gateway + Lambda 짝궁
• Gateway endpoints for S3 => low cost
• AWS accounts => IAM role 필요 없음
• Low latency from on-premises + s3 => File gateway
• Backup / migration => Volume gateway
• ALB + NAT => public subnet
• EC2 application servers => private subnet
• ECS =/= resource based policy
• EC2 + big data analysis => Spot Fleet(spot + on-demand)
• no traversing the www => endpoints
• HPC => FSx Lustre
