What it is

AWS (Amazon Web Services) is the world’s largest cloud platform — over 200 services covering compute, storage, databases, networking, security, AI / ML, IoT, analytics, developer tools, content delivery, and more. It’s a separate division of Amazon (the e-commerce parent) and far larger than the e-commerce business in terms of profit.

AWS effectively defined the modern cloud-services category starting in 2006 with EC2 (rentable compute), S3 (storage), SQS (message queues). It has dominated the cloud market ever since, with ~30-33% global cloud market share as of mid-2026.

For AI specifically, AWS provides:

  • AWS Bedrock — managed access to Claude, Llama, Mistral, Cohere, Amazon Nova models (see aws-bedrock.md)
  • Amazon Q — Business (enterprise AI assistant) + Developer (coding AI)
  • Amazon SageMaker — ML platform for training / deploying your own models
  • Amazon Nova — Amazon’s own foundation model family
  • AWS Trainium / Inferentia — custom AI chips
  • Cloud GPUs via EC2 P-series, G-series (Nvidia hardware)

For Australian customers specifically, AWS has unique strengths:

  • Two AUS regions: Sydney (ap-southeast-2, established 2012) and Melbourne (ap-southeast-4, established 2023) — strong for data sovereignty + low latency
  • IRAP Protected assessment — assessed at PROTECTED level by ASD for AUS government use
  • Strong AUS partner ecosystem — many AUS-based AWS consulting partners
  • AUD billing native via AWS Australia Pty Ltd
  • Used by: Atlassian, Canva, REA Group, Carsales, Telstra (many workloads), Westpac, ANZ, NAB (specific workloads), AUS government departments

What you’d use it for

Infrastructure

  • Host web apps (EC2 / ECS / Fargate / Lambda)
  • Store data (S3 for files, RDS for SQL, DynamoDB for NoSQL, OpenSearch, etc.)
  • Network (VPC, Route 53 DNS, CloudFront CDN)
  • Email (SES — Simple Email Service)

AI / ML

  • Run inference on Bedrock (Claude / Llama / Nova / etc.)
  • Train custom models (SageMaker)
  • Add AI features to apps (Comprehend NLP, Rekognition vision, Polly TTS, Transcribe STT)
  • Cloud GPUs for model training / fine-tuning

Data

  • BigQuery-style analytics (Athena, Redshift)
  • Data lakes (S3 + Glue + Lake Formation)
  • Real-time streaming (Kinesis)

Developer tools

  • Source control + CI/CD (CodeCommit, CodeBuild, CodePipeline, CodeCatalyst)
  • Container registry + orchestration (ECR, EKS, Fargate)
  • Observability (CloudWatch, X-Ray)

For Bible Quest-scale projects, AWS is overkill — Vercel + Supabase covers similar ground at much lower complexity. AWS shines for larger / enterprise / heavy infrastructure.

How to sign up + first 5 minutes from Australia

  1. Go to aws.amazon.com. Click Create Free Account.
  2. Enter email, account name; verify
  3. Credit card required (AUS Visa / Mastercard / Amex accepted); won’t be charged for Free Tier usage
  4. Identity verification (phone + maybe ID for some accounts)
  5. Pick support plan — start with Basic (free)
  6. Sign in to AWS Console (console.aws.amazon.com)
  7. Set up MFA immediately on root account
  8. Create an IAM user for day-to-day work (don’t use root after initial setup)
  9. Pick AUS region — ap-southeast-2 (Sydney) is the default for AUS customers
  10. Try Free Tier services: spin up a t2.micro EC2 instance, S3 bucket, Lambda function

What it costs

Free Tier (12-month free, always-free, trials)

  • EC2 t2.micro/t3.micro: 750 hours/month (~1 always-on instance)
  • S3: 5GB storage, limited requests
  • RDS: 750 hours of small instance + 20GB storage
  • Lambda: 1M requests/month always-free
  • DynamoDB: 25GB storage always-free
  • Bedrock: some free quota for development
  • Many smaller services: always-free at low usage

Pay-as-you-go (most customers)

  • Per-second / per-hour / per-GB / per-request pricing
  • Pricing varies massively by service + region + tier
  • AUD billing via AWS Australia
  • Sydney region is typically slightly more expensive than US-East (us-east-1) — pay for AUS data residency

Enterprise discounts

  • Reserved Instances (commit to 1- or 3-year usage for ~30-70% off)
  • Savings Plans (flexible commitments)
  • Enterprise Discount Program (negotiated discounts for large customers)
  • AWS Marketplace Private Offers (vendor-discounted bundles)

Hidden costs to know about

  • Data egress (data leaving AWS) is the most common surprise — can be ~AUD $0.15/GB; large outflows add up
  • NAT Gateway, Load Balancer, RDS can accumulate at low-medium usage
  • Forgotten resources — leaving EC2 / RDS / NAT Gateway running unintentionally
  • Cross-region replication has both data-egress + storage costs
  • AWS Bills tab + Cost Explorer + Budgets — set alerts to catch surprises early

For most AUS organisations starting fresh: AWS if AI-heavy / multi-vendor; Azure if M365-heavy; GCP if Workspace-heavy / Google AI-heavy; Cloudflare if edge-AI-heavy or developer-velocity-focused.

Privacy / data handling

  • Customer data is yours — AWS doesn’t access without explicit permission
  • No training on customer data in Bedrock, SageMaker, Q (contractually)
  • AUS data residency via Sydney / Melbourne regions
  • IRAP Protected assessment for AUS government workloads
  • HIPAA, GDPR, SOC 2 Type II, ISO 27001, ISO 27017, ISO 27018 all compliant
  • Tenant-isolated by AWS account structure
  • Encryption at rest + in transit by default for most services
  • Audit logs via CloudTrail
  • Customer-managed encryption keys (CMK) via KMS

Recent changes

  • 2026: Nova family expanded; Amazon Q matured; new Sydney + Melbourne edge zones
  • 2025: AWS Trainium 2 launched; expanded Bedrock model catalogue
  • 2023: Melbourne region (ap-southeast-4) launched
  • 2012: Sydney region (ap-southeast-2) launched
  • 2006: S3, EC2, SQS launched

Gotchas

  • AWS is huge — 200+ services is genuinely overwhelming; start small
  • Pricing complexity is the #1 surprise — use Calculator (calculator.aws) before committing
  • Egress costs trap many users — modelling them is essential
  • Console UI is dense — the AWS Console is functional but not friendly; CLI / SDK / Terraform often easier for repeated tasks
  • For small projects, Vercel + Supabase / Cloudflare offer simpler experience
  • AWS Certified certifications are valuable for AUS IT careers — Solutions Architect Associate is the common starting point
  • IAM (Identity and Access Management) is genuinely hard — most AWS security incidents trace to IAM misconfiguration
  • Save your AWS Free Tier email — billing surprises if you exceed Free Tier without realising
  • Australian Privacy Act: AWS publishes APP-compliant Data Processing Addendum; valid for AUS personal-information handling
  • For tax-invoice handling (Australian businesses), enable AWS Australia billing entity properly
