There is no consistent architecture pattern, security configurations vary by account, and operational procedures exist only in the heads of the engineers who built each component. When the original architect left, institutional knowledge walked out the door. You need a documented, repeatable architecture pattern that new team members can understand and extend.\u003c\/p\u003e\n\n\u003cp\u003eThis blueprint is based on enterprise AWS architectures I have deployed across Fortune 500 environments — standardizing design patterns that reduce onboarding time from weeks to days and operational incidents by 40% through consistent, well-documented infrastructure.\u003c\/p\u003e\n\n\u003ch3\u003eWhat You Get\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArchitecture diagrams\u003c\/strong\u003e — Complete system topology, data flow paths, security boundaries, scaling triggers, and failure modes (Draw.io and Visio)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerraform modules\u003c\/strong\u003e — Production-ready infrastructure code with security hardening, monitoring, and operational automation built in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperational runbook\u003c\/strong\u003e — Day-1 deployment guide, day-2 operations procedures, scaling playbook, and incident response steps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCost model\u003c\/strong\u003e — Detailed cost breakdown by component, optimization recommendations, and reserved capacity analysis\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Architecture Decisions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-AZ by default\u003c\/strong\u003e — Every stateful component (RDS, ElastiCache, EFS) deploys across at least 2 Availability Zones.

Deploy the networking Terraform module (VPC, subnets, route tables, VPC endpoints) into a sandbox account. On day two, deploy one compute workload using the provided ECS or EC2 module and verify it can reach AWS services through VPC endpoints without internet access. This validates the foundational networking layer that all other components depend on.\u003c\/p\u003e\n\n\u003ch3\u003eLimitations and Trade-offs\u003c\/h3\u003e\n\u003cp\u003eVPC endpoints cost $7-22\/month each; a fully private VPC typically requires 8-12 endpoints adding $100-250\/month. NAT Gateway costs $32\/month plus $0.045\/GB processed — high-egress workloads should consider NAT instances for cost savings at the expense of managed availability. The Terraform modules target AWS provider v5.x — older provider versions require modifications. Multi-AZ deployments incur cross-AZ data transfer charges ($0.01\/GB) that can be significant for chatty inter-service communication.\u003c\/p\u003e","brand":"Citadel Cloud Management","offers":[{"title":"Default Title","offer_id":54890409066787,"sku":"CCM-ARC-030","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/8539\/7027\/files\/citadel-architecture-product_80b8c682-de19-4e7c-ab2b-6f61ae0174ed.jpg?v=1775138182","url":"https:\/\/www.citadelcloudmanagement.com\/products\/mobile-backend-architecture-firebase-aws","provider":"Citadel Cloud Management","version":"1.0","type":"link"}
