Answers
(MySQL/PostgreSQL-compatible): high perf/availability; Serverless option for
infrequent/variable usage
Aurora
managed NoSQL (supports key-value or document); global tables; DAX cache;
SINGLE-DIGIT millisecond latency; unstructured data; millions of requests per second
DynamoDB
GRAPH DB (fraud finding/relationship queries); highly connected data
Neptune
managed data warehouse (petabyte-scale)
Redshift
serverless SQL searches on S3
Athena
use natural language searching to multiple data repos; uses machine learning
Kendra
discover PII in S3, alert on data exposure
Macie
Responsibilities: data, IAM, OS/apps on EC2, S3 bucket policies, security
groups/NACLs, client-side encryption choices
Customer
, Responsibilities: physical security; Regions/AZ infra; hypervisor; managed-service
underlying infra patching
AWS
CDN for global low latency; integrates with WAF/Shield
Cloudfront
static anycast IPs; improves TCP/UDP app availability/latency.
Global Accelerator
ALB (HTTP/HTTPS), NLB (TCP/UDP), GWLB (appliance)
Elastic Load Balancing
serverless containers for ECS/EKS; measured in $/hour; 1 or 3 year term
Fargate
deploy and scale web apps that use Java/.NET/Node/etc. → auto capacity, LB, scaling,
health
Elastic Beanstalk
serverless functions (event-driven); AWS manages everything except business logic; you
are charged based on length of execution of functions aka compute time
Lambda
managed virtual/cloud desktops; remote windows desktop anywhere
