AWS Services Overview
A structured catalogue of the major AWS services — organised by category so you can explore compute, storage, networking, databases, security, integration, analytics, management, AI/ML, and DevOps in one place.
Amazon Web Services offers 200+ managed services spanning infrastructure, application development, data analytics, machine learning, and operations. This page groups the most important services into 12 categories — each linking to a dedicated deep-dive page where you'll find architecture diagrams, configuration guides, and best practices.
Compute
On-demand processing power — from virtual machines and containers to serverless functions.
Amazon EC2
Resizable virtual machines with full OS control — instance types, AMIs, placement groups, and auto-scaling.
ECS & Fargate
Container orchestration — ECS task definitions, Fargate serverless containers, and service auto-scaling.
AWS Lambda
Event-driven serverless compute — triggers, runtimes, layers, concurrency, and cold-start optimisation.
Elastic Beanstalk
PaaS deployment for web apps — auto-provisioned EC2, load balancers, and managed platforms.
Other Compute
Lightsail, Batch, Outposts, Wavelength, and additional compute offerings.
Storage
Durable, scalable object, block, and file storage for every workload.
Amazon S3
Object storage with 11 9s durability — buckets, storage classes, lifecycle policies, versioning, and encryption.
Amazon EBS
Block storage volumes for EC2 — gp3, io2, throughput-optimised, and snapshot management.
Amazon EFS
Managed NFS file system — elastic capacity, throughput modes, and cross-AZ access.
Other Storage
FSx, Storage Gateway, Snow Family, and additional storage services.
Networking
Virtual networks, DNS, content delivery, load balancing, and API management.
Amazon VPC
Isolated virtual networks — subnets, route tables, NAT gateways, security groups, and NACLs.
Route 53
Scalable DNS and domain registration — routing policies, health checks, and hosted zones.
CloudFront
Global CDN — edge locations, caching behaviours, origin failover, and Lambda@Edge.
Elastic Load Balancing
ALB, NLB, and GLB — target groups, health checks, sticky sessions, and cross-zone balancing.
API Gateway
Managed REST & WebSocket APIs — stages, throttling, authorisers, and usage plans.
Other Networking
Direct Connect, Transit Gateway, Global Accelerator, PrivateLink, and more.
Database
Purpose-built managed databases — relational, key-value, in-memory, and more.
Amazon RDS
Managed relational databases — MySQL, PostgreSQL, Oracle, SQL Server, and Multi-AZ deployments.
Amazon Aurora
MySQL/PostgreSQL-compatible with 5× throughput — Serverless v2, Global Database, and read replicas.
DynamoDB
Serverless NoSQL — single-digit-ms latency, on-demand capacity, streams, and global tables.
ElastiCache
Managed Redis & Memcached — sub-millisecond caching, replication groups, and cluster mode.
Other Databases
Neptune, DocumentDB, Keyspaces, Timestream, and QLDB.
Security
Identity, encryption, secrets management, and compliance services.
AWS IAM
Users, groups, roles, and policies — fine-grained access control across your entire AWS estate.
AWS KMS
Managed encryption keys — symmetric/asymmetric, automatic rotation, and envelope encryption.
Secrets Manager
Rotate, manage, and retrieve database credentials, API keys, and other secrets at scale.
Other Security
WAF, Shield, GuardDuty, Inspector, Macie, Security Hub, and Certificate Manager.
Integration
Messaging, event routing, and application-integration services for decoupled architectures.
Amazon SNS
Pub/sub messaging — topics, fan-out, filtering, and push notifications.
Amazon SQS
Fully managed message queues — standard vs. FIFO, dead-letter queues, and visibility timeout.
EventBridge
Serverless event bus — rules, schema registry, cross-account events, and archive/replay.
Other Integration
Step Functions, AppSync, MQ, and additional integration services.
Analytics
Data lakes, ETL, streaming, and warehousing at cloud scale.
Athena
Serverless SQL queries directly against S3 data — Presto engine, partitions, and cost control.
AWS Glue
Managed ETL — crawlers, Data Catalog, Spark jobs, and schema evolution.
Kinesis
Real-time streaming — Data Streams, Firehose, and Analytics for high-throughput ingestion.
Redshift
Cloud data warehouse — columnar storage, Spectrum, concurrency scaling, and RA3 nodes.
Other Analytics
QuickSight, Lake Formation, EMR, MSK, and OpenSearch.
Management & Operations
Monitoring, auditing, configuration tracking, and operational tooling.
CloudWatch
Metrics, logs, alarms, and dashboards — unified observability across all AWS resources.
CloudTrail
API activity logging — governance, compliance auditing, and operational troubleshooting.
AWS Config
Resource inventory and configuration history — conformance packs and remediation rules.
Systems Manager
Operational hub — Session Manager, Parameter Store, Patch Manager, and Run Command.
Other Management
Trusted Advisor, Health Dashboard, Organizations, Control Tower, and Service Catalog.
AI & Machine Learning
