AWS Service Comparisons & Migration Guides
Objective, detailed comparisons to help you choose the right AWS services — plus step-by-step migration guides for teams moving to AWS from competing platforms.
AWS Service Comparisons
Compare AWS services side-by-side to choose the right architecture for your workload.
A technical comparison of Amazon Q Business and ChatGPT Enterprise covering data residency, enterprise system integration, IAM-based permissions, HIPAA eligibility, and compliance certifications for regulated industries.
A technical comparison of Aurora Serverless v2 and Aurora Provisioned — covering ACU pricing, cold start behavior, scaling characteristics, production readiness, and when serverless genuinely saves money.
A technical comparison of Amazon Bedrock Agents and AWS Step Functions covering AI reasoning vs deterministic execution, dynamic tool use, error handling, hybrid architectures, cost, and when to use each for workflow orchestration on AWS.
A practical comparison of AWS Bedrock and SageMaker for CTOs and ML architects — covering the build-vs-use model decision, cost structures, fine-tuning capabilities, and when each service is the clear choice.
A technical comparison of AWS CodePipeline and GitHub Actions covering IAM integration, pricing at different pipeline volumes, AWS-native deployment advantages, and when each platform is the better choice.
A first-principles comparison of AWS EC2 and Lambda covering cost crossover points, architectural trade-offs, Lambda limitations, and a practical decision framework for CTOs and cloud architects.
A practical comparison of Amazon ECS and EKS for cloud architects — covering control plane costs, operational complexity, Kubernetes ecosystem benefits, and when each service wins.
A detailed technical comparison of AWS Lambda and ECS Fargate — covering execution models, cold starts, timeout limits, cost at scale, and when to choose each for your architecture.
A technical comparison of Amazon RDS and Aurora — covering architecture differences, hidden I/O costs, high-availability features, and the actual cost crossover point for different workload sizes.
A technical comparison of AWS Step Functions and EventBridge covering orchestration vs choreography patterns, error handling, execution guarantees, cost at scale, and when to combine both services.
A technical comparison of Amazon DynamoDB and RDS for AWS architects — covering data models, access pattern rigidity, hot partition risks, cost models, and the workloads where each clearly wins.
Cloud Platform Comparisons
AWS vs major cloud competitors — which platform fits your use case, compliance needs, and budget.
A technical comparison of AWS CloudFront and Cloudflare covering WAF pricing models, edge compute capabilities, free tier differences, DDoS protection, and integration depth with the AWS ecosystem.
An objective comparison of AWS and Microsoft Azure for enterprise workloads — covering services, pricing, security, compliance, and decision criteria to help CTOs choose the right platform.
A practical comparison of AWS and Google Cloud Platform for startups — covering free tiers, startup credits, pricing, developer experience, and the services that matter most at each growth stage.
Cloud Migration Guides
Moving to AWS from another platform? Step-by-step guides for a smooth, low-risk migration.
A practical guide to migrating from DigitalOcean to AWS — covering service equivalents, cost comparison, migration approach, and when AWS is (and is not) the right move.
A practical guide to migrating from Google Cloud Platform to AWS — service equivalents, cost model differences, the BigQuery decision, and a phased migration approach for DevOps and engineering teams.
A practical guide to migrating from Heroku to AWS — covering Postgres to RDS migration steps, Dyno-to-EC2/Fargate decisions, buildpack-to-Docker conversion, CI/CD re-plumbing, and cost comparison.
An honest comparison of MongoDB Atlas and Amazon DocumentDB — covering compatibility gaps, when DocumentDB makes sense, when to stay on Atlas, migration steps, and cost breakdown.
Email Platform Migration Guides
Migrate from SendGrid, Mailgun, Postmark, or SparkPost to Amazon SES — with full deliverability setup.
A technical migration guide for engineers moving from Mailgun to AWS SES — covering pricing differences, routing rule migration, EU data residency, webhook event mapping, and suppression list portability.
A practical guide for engineering teams evaluating the move from Postmark to AWS SES — covering the cost difference, message stream equivalents, template migration, and the deliverability trade-offs you need to understand first.
A practical migration guide for engineers moving from SendGrid to AWS SES — covering pricing math, API differences, template migration, bounce handling, and IP warming strategy.
A migration guide for engineers moving off SparkPost (now Bird) to AWS SES — covering the acquisition context, pricing comparison, Transmission API mapping, Signals analytics alternatives, and step-by-step migration instructions.
