AWS SAA(C02) - "Ring the bell" keywords

Hello friends, this post is about the important keywords and the associated AWS services which should ring the bell? 

Although after sufficient practice you may not need it, however, If you feel overwhelmed by the number of services AWS provides you can use this list before the exam (to help eliminate some options given for the question).

Here you go:

Keyword	AWS Service
DDoS	AWS Shield is the right service(Select if AWS WAF if AWS Shield is not there as an option)
Security service to build “High visibility” websites	AWS Shield, DDoS are most common, AWS Shield can help prevent
Most stringent RPO/RTO	MultiAZ RDS
Missed transactions	Think of SQS
Improve Database performance	Think of elastic cache service, Redis, Memcached. Select Redis if the question is expecting many features to be available
Improve Database “read” performance	Read replicas (you will practice this enough 😊)
IAM role	Remember role is for an AWS service to access another AWS service
Personally, Identifiable Information (PII)	If there is an option with S3 select Macie service
Redshift with S3	Redshift spectrum
Leader board game	Redis(with sorter sets feature)
One webpage(domain#1) trying to access another origin	S3 CORS(Cross-Origin resource sharing)
Serverless + SQL analytics on S3	AWS Athena
Decoupling services and architecture	Think of SQS
Duplicate message	SQS message visibility timeout
Realtime data	Think of Kinesis
Improving Dynamo DB performance	Think if DAX (Dynamo DB accelerator)
Tasks more than 15min	Lamda cannot help here, the max time for a lambda service is 15min
Login using Google, Facebook Ids	Think of AWS Cognito
Search, Indexing, Partial search	Elastic Search
Analytics/BI/Datawarehouse	AWS Redshift
Low latency between EC2	Think of placement groups
ETL, Metadata catalog	AWS Glue
Usage Data, Forecast Usage	CostExplorer service
Workflow+ state machine + Orchestration function	AWS StepFunction
Automation using stacks	AWS CloudFormation
Chef, Puppet	AWS OpsWorks
Automatic password rotation	AWS Secret Manager
