Choosing the right AWS services for a web application

How to select a restrained AWS architecture for compute, databases, storage, queues and delivery. This guide explains the practical decisions behind it and what those decisions mean for the people using and operating the product.

Start from workload responsibilities

Identify web traffic, background jobs, scheduled work, storage, databases and integrations. Map services only after availability, scale and team constraints are understood.

Choose compute the team can operate

Virtual machines offer control, containers improve packaging and managed or serverless options remove some infrastructure work. Each route changes debugging, deployment and cost behaviour.

Use managed data services purposefully

RDS can reduce database administration, ElastiCache can support Redis workloads and S3 provides durable object storage. Managed services still require access controls, monitoring and tested recovery.

Avoid service sprawl

Every additional product adds permissions, billing, logs and skills. A modest architecture with clear boundaries is usually easier to secure and evolve.

Document why each service exists

A decision record should state the requirement, alternatives and owner. This makes later simplification possible when assumptions change.
